Block of Flats Insurance UK: Costs, Rules & RTM Guide
Why has UK block of flats insurance changed completely in 2026?
For decades, block of flats insurance ran on autopilot. The freeholder or managing agent renewed the policy each year, often with the same insurer, and recovered the premium from leaseholders through the service charge. Few leaseholders saw the policy document, fewer still understood the commission flowing back to the agent, and almost none knew they had the right to challenge any of it. That world is over.
Three regulatory transformations have converged in 2025-2026 to rewrite the rules. First, the Financial Conduct Authority redefined leaseholders as customers of multi-occupancy buildings insurance under ICOBS 6A.7, with effect from 31 December 2023 — meaning insurers and brokers must act in leaseholders' best interests, disclose all commission, and demonstrate fair value. Second, the Leasehold and Freehold Reform Act 2024 gives the government power to replace freeholder and managing agent commission with transparent "permitted insurance fees". Those provisions were targeted for April 2026 but, at the time of writing, still await commencement through secondary legislation. Third, the Building Safety Act 2022 remediation framework continues to reshape the rating of any block above 11 metres, with leaseholder protections under Schedule 8 fundamentally changing who pays for what.
The downstream effect on freeholders, Right to Manage (RTM) companies, Resident Management Companies (RMCs), and managing agents is profound. Buying block of flats insurance in 2026 isn't a transactional renewal — it's a regulated process where the wrong placement, the wrong commission structure, the wrong sum insured, or the wrong disclosure can trigger leaseholder challenge at the First-tier Tribunal, FCA scrutiny of the broker, or — in the event of a major claim — an underinsurance penalty that exposes the freeholder to direct personal liability.
This guide is the definitive 2026 UK block of flats insurance article — built around who actually needs to buy it, the regulatory transformation that's changed the rules, the dominant claim exposures (escape of water, fire, subsidence, cladding remediation), and the broker placement disciplines that produce defensible, fair-value cover. It complements our block of flats insurance page and our commercial property insurance page and sits alongside our property cluster including the high-value residential landlords guide and the overseas investors in UK property placement service.
Key facts at a glance
- FCA rules from 31 December 2023 treat leaseholders as customers of multi-occupancy buildings insurance — insurers and brokers must act in leaseholders' best interests, make sure remuneration does not drive the choice of policy, and disclose the commission paid to freeholders, managing agents and third parties.
- The Leasehold and Freehold Reform Act 2024 will replace commission with "permitted insurance fees" — sections 61 to 64 allow the government to limit what landlords and managing agents can recover for insurance work to defined, transparent fees. The provisions were targeted for April 2026 and still await commencement through secondary legislation.
- Escape of water is now the dominant block of flats claim category — ageing pipework, flexible hoses, and multi-storey water cascading mean a single leak can damage multiple flats simultaneously. Claim frequency in multi-unit blocks is materially higher than in single dwellings.
- The Building Safety Act 2022 protects qualifying leaseholders from cladding remediation costs — Schedule 8 protections apply to blocks above 11 metres or 5 storeys with relevant defects from 28 June 1992 to 27 June 2022. EWS1 forms have become a de facto requirement for insurers to underwrite blocks with cladding.
- Underinsurance is widespread across UK property — and blocks of flats are particularly exposed because rebuild values rarely keep pace with construction cost inflation. Average clause penalties reduce claim payments proportionally.
- Premiums vary widely by block — construction, height, cladding status, claims history and the accuracy of the rebuild value matter far more than the number of flats. Indicative per-flat ranges from our own placements are set out in the cost section below.
- Section 20 of the Landlord and Tenant Act 1985 requires consultation with leaseholders on long-term agreements (over 12 months) above the prescribed threshold. Failure to consult limits recovery to £100 per leaseholder per year. Most block insurance is placed annually — multi-year agreements offered for a premium reduction need careful handling.
1. Who actually buys block of flats insurance — freeholder, RTM, RMC or managing agent?
The first source of confusion in block of flats insurance is who is legally responsible for arranging it. The lease answers this — and there are four common structures.
Freeholder direct
In the most common arrangement, the freeholder owns the building, holds the freehold title, and is contractually required by the lease to insure the whole structure. They arrange the policy, pay the insurer, and recover the cost through the service charge. The freeholder remains the named policyholder and the insured party. Leaseholders are not the policyholder but are now defined by the FCA as policy stakeholders with rights of disclosure and challenge.
Right to Manage (RTM) company
Under the Commonhold and Leasehold Reform Act 2002, leaseholders in a qualifying block can take over management functions from the freeholder by forming a Right to Manage company. The RTM doesn't own the freehold but assumes the management functions including arranging buildings insurance. RTM directors are typically resident leaseholders, often unpaid, and they take on personal director-level responsibility for procurement decisions including insurance.
Resident Management Company (RMC)
Many newer developments are structured with a Resident Management Company built into the lease from the outset. The RMC has insurance arrangement as a contractual duty under the lease. RMCs sometimes also own the freehold (where leaseholders have collectively enfranchised) or operate under a tripartite lease with a separate freeholder. RMC directors face the same personal director-level responsibility as RTM directors.
Managing agent appointed by any of the above
Most freeholders, RTM companies, and RMCs appoint a professional managing agent to handle day-to-day management including procurement of insurance. The managing agent acts as agent for the principal — the freeholder remains the legal customer of the insurance, but the agent transacts on their behalf. Under the FCA rules from 2023, where the agent receives commission from the broker, that commission must now be disclosed to leaseholders, and once the LFRA 2024 permitted insurance fees regime is commenced it will be replaced by transparent, defined fees.

2. What are the 8 biggest block of flats insurance risks: summary table
The risks below are ranked by combined frequency, severity, and regulatory consequence under the 2026 framework. Some — escape of water, underinsurance — are everyday operational realities. Others — Section 20 consultation failure, leaseholder Tribunal challenge — are infrequent but consequential when they occur. The intelligent freeholder, RTM director, or managing agent manages all eight simultaneously.
| Risk | Frequency | Severity | Primary Cover Response |
|---|---|---|---|
| Escape of water — multi-flat cascade | Very common — the dominant claim | Medium-High — multi-flat cascades | Buildings (with EOW cover and sub-limit review) |
| Fire — communal or flat-origin | Occasional | Catastrophic — whole-building exposure | Buildings (with full reinstatement value) |
| Cladding / EWS1 / Building Safety Act exposure | Building-specific (high-rise only) | Catastrophic if uninsured remediation | Specialist placement, BSA leaseholder protections |
| Subsidence and structural movement | Postcode and soil dependent | High — underpinning and monitoring | Buildings (with subsidence scope) |
| Property owners' liability — communal areas | Common (slips, falls, falling debris) | Medium — serious injuries can be high value | Property Owners' Liability £5m-£10m |
| Underinsurance / average clause penalty | Widespread | Variable — proportional claim reduction | RICS-style Reinstatement Cost Assessment |
| Loss of rent / alternative accommodation | Triggered by major insured event | Medium-High (12-24 months × rents) | Loss of Rent extension on Buildings policy |
| Leaseholder Tribunal challenge / FCA non-compliance | Rising — under FCA rules and LFRA 2024 | Reputational + service charge limitation | Compliant placement, full commission disclosure |
3. How do the FCA leaseholder rules and the coming commission reforms change the broker relationship?
The block insurance broker market has been under unprecedented regulatory scrutiny since the FCA's September 2022 report on multi-occupancy buildings insurance. Its April 2023 follow-up review of broker remuneration was stark: remuneration had risen by nearly 40% between 2019 and 2022, and the 16 brokers in its sample paid over £80 million of commission to freeholders, property managing agents and other parties over the period. In many cases, brokers couldn't articulate what insurance-related work or value the commission recipients were actually providing.
The FCA reforms — already in force from December 2023
The FCA's response has unfolded in stages. From 31 December 2023, ICOBS 6A.7 of the FCA Handbook explicitly defined leaseholders as customers of multi-occupancy buildings insurance, with the following enforceable requirements on insurers and brokers:
- Act in leaseholders' best interests — not just the named policyholder's (the freeholder or managing agent).
- Remuneration must not drive the recommendation — conflicts of interest must be managed so the policy is selected on value to the customer, not broker or agent income.
- Mandatory disclosure of all commission — including amounts paid to freeholders, managing agents, and third parties, provided to leaseholders as soon as reasonably practicable after policy inception and at every renewal.
- Fair value assessment — under the Consumer Duty framework, brokers and insurers must be able to demonstrate the policy provides fair value to the leaseholder-customer.
The LFRA 2024 permitted insurance fees regime — awaiting commencement
The Leasehold and Freehold Reform Act 2024 goes further. Sections 61 to 64, once commenced through secondary legislation, will limit what landlords and managing agents can recover for insurance work to "permitted insurance fees" for defined activities, with full transparency to leaseholders. The government consulted on the detail in 2024 and set out its approach in 2025. Commencement was targeted for April 2026, but at the time of writing the regulations are still awaited.
What this means for freeholders, RTMs and managing agents in 2026
The combined effect of the FCA rules and the LFRA 2024 permitted insurance fees regime is that the historic block insurance economic model — where freeholders and managing agents derived material income from broker commission — is being dismantled. The replacement model is fee-based: a transparent fee for managing and arranging insurance, disclosed to leaseholders, with the broker's own remuneration also disclosed. Brokers who haven't restructured for this transition face FCA enforcement risk; freeholders and managing agents who continue to take commission post-commencement face Tribunal challenge and service charge recovery limitations.

4. How does the Building Safety Act 2022 affect block of flats insurance?
The Building Safety Act 2022 is the legislative response to the Grenfell Tower fire of 2017. It transformed the regulatory framework for buildings above 11 metres or 5 storeys ("relevant buildings"), introduced statutory duties on developers and building owners to remediate "relevant defects" from the 28 June 1992 — 27 June 2022 construction period, and created leaseholder protections under Schedule 8 that fundamentally changed who pays for what.
Qualifying leaseholders and Schedule 8 protections
A "qualifying leaseholder" under the Act is broadly a leaseholder who on 14 February 2022 used the property as their principal home, or owned no more than three UK residential properties. Qualifying leaseholders in relevant buildings cannot be charged for cladding remediation, and have capped contributions for non-cladding safety defects (capped over 10 years, with caps lower in lower-value properties). Building owners and developers are now legally required to fund the bulk of remediation, with government funding through the Building Safety Fund (18 metres and over) and the Cladding Safety Scheme (11 to 18 metres, which replaced the Medium Rise Scheme pilot) where developers cannot be pursued.
EWS1 and underwriting acceptance
The External Wall System certificate (EWS1) has become a de facto requirement for insurers underwriting blocks with any cladding above 11 metres. EWS1 is not a Building Safety Act requirement strictly — it's a RICS valuation-driven artefact that emerged from the post-Grenfell mortgage market — but insurers now routinely require it as part of their underwriting submission. EWS1 outcomes — A1 to A3 (no combustible materials of concern), B1 (combustible materials present but fire risk assessed as sufficiently low) and B2 (remedial works required) — determine whether mainstream insurers will quote, what loadings apply, and whether terrorism cover is freely available.
What this means for block of flats insurance placement
For blocks above 11 metres, the underwriting submission in 2026 typically requires: current EWS1 certificate; fire risk assessment (FRAEW for external walls where applicable); safety case report where the block is a higher-risk building under the BSA (18 metres or 7 storeys and over); details of any active remediation works; details of any government scheme application or contractual position with the developer. Blocks without EWS1 or with a B2 rating face restricted markets, heavy loadings, and sometimes refusal at standard markets — requiring specialist Lloyd's or MGA placement.
5. What does block of flats insurance actually cover in 2026?
A comprehensive 2026 block of flats policy covers the building structure, communal areas, and core liability exposures that a freeholder, RTM, or RMC carries by virtue of owning or managing the building. Individual flat contents are not covered — those remain the leaseholder's individual responsibility through their own contents policy.
Core covers — what should always be included
- Buildings — full reinstatement value: the building structure including roofs, external walls, floors, staircases, windows, doors, communal lifts, plant rooms, and all permanent fixtures. Reinstatement should be calculated by RICS-style Reinstatement Cost Assessment, not market value, and reviewed annually for construction cost inflation.
- Communal areas: hallways, stairwells, lifts, bin stores, gardens, parking areas, and any outbuildings demised under the freehold/lease.
- Standard perils: fire, lightning, explosion, aircraft, storm, flood, escape of water, escape of oil, theft (with forcible entry), malicious damage, impact (vehicles and falling objects), subsidence, accidental damage to building services.
- Property Owners' Liability: £5m typical, £10m where contracts require — covers injury claims from residents and visitors in communal areas, and third-party damage caused by the building (falling debris, lift incidents, escape of water onto neighbouring property).
- Loss of rent / alternative accommodation: typically 24-36 months of recoverable rent or actual reasonable cost of rehousing leaseholders where flats become uninhabitable after an insured event.
- Public Liability extension for the management entity's activities.
- Engineering inspection: statutory inspection of lifts, lifting equipment, pressure systems, and boilers under the Lifting Operations and Lifting Equipment Regulations 1998 (LOLER) and the Pressure Systems Safety Regulations 2000.
Important extensions to consider
- Terrorism cover: often required by leaseholder mortgage lenders, particularly in London and major cities. Pool Re backed where placed through the standard market; some specialist markets carry standalone terrorism.
- Directors and Officers cover for RTM/RMC directors: protects volunteer leaseholder directors against personal liability for management decisions including insurance procurement. Often overlooked but materially important.
- Communal contents: shared furniture in communal areas, gym equipment, communal entry systems, CCTV — usually a modest sub-limit but worth setting realistically.
- Legal Expenses: cover for property disputes, leaseholder disputes, and contract challenges including Tribunal proceedings.
- Engineering breakdown: lift breakdown, boiler breakdown, communal plant — separate from inspection, covers mechanical failure.
6. Risk 1: Escape of water — the dominant claim category
Escape of Water — The Dominant Multi-Flat Claim
Escape of water is consistently the single largest claim category for UK block of flats insurance — both in frequency and aggregate cost. The dynamics that make it dominant for blocks are structural: water from a burst pipe, failed appliance hose, or leaking radiator in a fifth-floor flat doesn't stay in that flat. It cascades through the floor structure to the fourth, third, second, and ground-floor flats below, and can spread laterally through party walls. A single £400 burst hose creates damage across multiple flats — plasterboard ceilings, decorations, flooring, sometimes electrical systems, and (worst case) structural timber and concrete drying-out costs. A severe multi-flat cascade can run well into six figures.
Communal water shut-off systems with annual testing; leak detection technology (now increasingly available as IoT installation) on communal risers; mandatory flexible hose replacement programme via lease covenant or service charge schedule; pipework inspection regime on ageing buildings (pre-1970 stock particularly); requirement in tenancy/lease terms for tenant notification of any leak; clear winter precautions for vacant flats including thermostat minimums; documented annual maintenance of communal heating systems and risers.
Escape of water is included as a standard peril on all credible block of flats policies — but the sub-limits, excess structure, and trace-and-access scope vary enormously. Specialist placement should secure: standard buildings limit applicable to EOW (not separately sub-limited); reasonable excess (£250-£500 typical; some insurers push £1,000+ on poor claims experience blocks); trace and access cover (the cost of finding the leak source through walls/floors); alternative accommodation cover. Claims experience of 2+ EOW claims in 5 years typically triggers loadings and excess uplift; 3+ claims triggers conditions (e.g. mandatory leak detection installation).
If repeated leaks have already loaded your renewal or led to a non-renewal, see block of flats insurance after a claim.
7. Risk 2: Fire, cladding and EWS1 exposure
Fire and Cladding — The Catastrophic Exposure
Fire is the catastrophic exposure for blocks of flats. A single fire in one flat can spread through cavity routes, common ducting, or compromised compartmentation to threaten the whole block. The post-Grenfell underwriting environment has materially tightened underwriting acceptance for any block above 11 metres, and EWS1 has become a routine submission requirement. Where cladding needs remediation (ACM, HPL with combustible insulation, or other systems graded B2), mainstream insurers either decline, sub-limit, or apply substantial loadings. Specialist Lloyd's and MGA markets fill the gap but at materially higher cost until remediation is completed.
Fire risk assessment under the Regulatory Reform (Fire Safety) Order 2005 — annual review for low-risk, more frequent for higher-risk; compliance with the Fire Safety (England) Regulations 2022 for blocks above 11 metres including external wall information to fire and rescue authorities; current EWS1 certificate where any external wall system is present; a current safety case report for higher-risk buildings under the BSA; sprinkler systems where present should be commissioned and tested; fire door inspection regime under the Fire Safety (England) Regulations 2022; clear escape route signage and emergency lighting compliance; engagement with developer or government scheme for cladding remediation funding where applicable.
Buildings cover with full reinstatement value is the primary response. Where reinstatement cost has been assessed against current construction inflation, the policy will respond fully. Where underinsurance exists, the average clause applies (proportional reduction). For cladding-affected blocks: standalone cladding remediation cover is not insurance — it's developer/government funded under the BSA and Building Safety Fund. The buildings policy responds to fire damage; the remediation programme is separate. Total losses on larger blocks can exceed reinstatement values where underinsurance has been allowed to develop.
8. Risk 3: Underinsurance and reinstatement cost gaps
Underinsurance — The Hidden Catastrophe
Underinsurance — where the declared sum insured falls below actual reinstatement cost — is the most common and most damaging hidden problem in UK block of flats insurance. Industry surveys have repeatedly found a large share of UK commercial properties underinsured, and blocks of flats are particularly exposed because: rebuild values are rarely reassessed at renewal; construction cost inflation compounds year on year; market value is often (wrongly) used as a proxy for reinstatement; managing agents inheriting accounts rarely commission new valuations. The consequence is the "average clause" — where claims are reduced proportionally to the underinsurance ratio. A block insured for £4m with actual reinstatement of £6m faces a 33% reduction on every claim, even small ones. A £100,000 escape of water claim pays out £67,000; the freeholder, RTM or RMC is left to fund the £33,000 shortfall.
Commission a RICS-style Reinstatement Cost Assessment every 3-5 years from a qualified building surveyor — the fee is small against the cover and audit trail it buys; uplift declared value annually for construction inflation (BCIS All-in TPI or similar published index); review immediately after any material building works, extension, or refurbishment; ensure declared value covers reinstatement to current building regulations standards, debris removal, professional fees (architect, surveyor, structural engineer), and contingency.
Insurance Act 2015 fair presentation duty applies — declared value is a material fact and must be presented honestly. Many specialist insurers offer day one reinstatement policies where the declared value is uplifted annually by an agreed index, removing some risk. Some markets offer reinstatement cost guarantees where the policyholder commissions a recent RICS assessment — the insurer waives average clause penalties. The Insurance Act 2015 "proportionate remedy" framework means honest but mistaken underinsurance is treated proportionally rather than as outright avoidance; deliberate misrepresentation is treated more harshly.

Block Insurance Red-Flag Self-Check
Click each red flag that applies to your current block of flats insurance. The more ticked, the more urgent the broker and policy review.
-
No RICS Reinstatement Cost Assessment in the last 5 years — declared value is likely materially below actual rebuild cost given recent construction inflation
-
The policy has auto-renewed for 3+ consecutive years without market retender — leaseholders can challenge "reasonableness" at the First-tier Tribunal without evidence of market testing
-
No FCA-aligned commission disclosure has been provided to leaseholders at the most recent renewal — required under ICOBS 6A.7 from 31 December 2023
-
The block is above 11 metres with cladding and no current EWS1 certificate — mainstream insurer acceptance restricted; underwriting submission incomplete
-
Multiple escape of water claims in last 5 years without a leak detection or pipework upgrade response — insurer may impose conditions, loadings, or excess uplifts
-
No D&O cover for RTM or RMC directors — volunteer directors carry personal liability for procurement decisions including insurance
-
No annual Fire Risk Assessment compliant with Regulatory Reform (Fire Safety) Order 2005 — direct regulatory exposure plus material insurance underwriting concern
-
Lifts or pressure systems not subject to current Engineering Inspection — LOLER 1998 / Pressure Systems Safety Regulations 2000 non-compliance
-
Managing agent receives undisclosed commission that exceeds typical insurance-related work — direct LFRA 2024 / FCA fair value concern, Tribunal exposure
-
Long-term insurance agreement over 12 months entered without Section 20 consultation — recovery from leaseholders limited to £100 per leaseholder per year on unconsulted amount
-
Terrorism cover absent where leaseholder mortgage lenders require it — leaseholders may be in breach of their own lender's conditions through no fault of their own
-
No Legal Expenses cover with Tribunal scope — leaseholder challenges and contract disputes increasingly common; defence costs uninsured

12. How does Section 20 consultation work and when does it apply to block insurance?
Section 20 of the Landlord and Tenant Act 1985 requires landlords (including freeholders, RTM and RMC companies) to consult with leaseholders before incurring certain costs that will be recovered through the service charge. The consequence of failing to consult is severe: the landlord can recover no more than £100 per leaseholder per year on the unconsulted amount, with the leaseholders entitled to challenge the rest at the First-tier Tribunal.
When does Section 20 apply to block insurance?
Two thresholds matter for insurance. First, "qualifying works" — where the cost to any single leaseholder exceeds £250 in any one year. Second, and more relevant to insurance, "qualifying long-term agreements" (QLTAs) — any agreement for the provision of services lasting more than 12 months where the cost to any single leaseholder will exceed £100 per year.
An annual block insurance policy renewed each year is not a QLTA. This is one reason most UK block insurance is placed on annual terms. However, multi-year deals offered for premium reduction can fall into the QLTA category, triggering full consultation requirements: Notice of Intention with reasons for the proposed agreement; consideration of leaseholder observations; obtaining at least two estimates; Notice of Proposal; further consideration period; final decision with documented reasoning.
The leaseholder challenge route
Under Section 30A of the Landlord and Tenant Act 1985, leaseholders have the right to request a summary of insurance and inspect the policy and supporting documents. Under Section 19, service charges (including insurance premiums recovered) must be reasonably incurred and the works of a reasonable standard. Leaseholders can apply to the First-tier Tribunal (Property Chamber) to challenge reasonableness — and the burden of proving reasonableness falls on the landlord. Documented evidence of market testing, FCA-compliant commission disclosure, and reinstatement value justification is the defence against such challenge.
13. What are leaseholders' actual rights to information and challenge?
Leaseholders sit in an unusual position: they pay for insurance through the service charge but are not the contractual policyholder. The combination of statute (Landlord and Tenant Act 1985), FCA regulation (ICOBS 6A.7), and the Leasehold and Freehold Reform Act 2024 has progressively expanded their rights of information and challenge.
Statutory information rights
- Section 21 LTA 1985 — right to a written summary of service charge expenditure including insurance.
- Section 22 LTA 1985 — right to inspect supporting documents.
- Section 30A LTA 1985 — specific right to a written summary of insurance and to inspect the policy and renewal documents.
- Section 47 LTA 1987 — landlord's name and address must appear on service charge demands; until it is supplied, the service charge is treated as not due.
FCA-imposed information rights (ICOBS 6A.7)
- Disclosure of policy terms — insurer details, sum insured, perils, exclusions, premium, excess.
- Commission disclosure — all remuneration paid by insurer to broker, broker to managing agent or freeholder, and any other commission flowing through the supply chain in connection with the policy.
- Reasons supporting placement — evidence the policy was selected on customer value not commission.
- Estimated leaseholder share — where the firm can reasonably estimate the leaseholder's portion of premium.
- Provided "as soon as reasonably practicable" after inception and at every renewal.
LFRA 2024 expanded rights (awaiting commencement)
- Right to detailed information about insurance commission proactively provided to leaseholders.
- Right to challenge the "permitted insurance fee" at the First-tier Tribunal where excessive.
- Strengthened service charge transparency with standardised statements.
14. Risk 4: Subsidence, structural movement and trees
Subsidence and Structural Movement — Postcode-Driven Severity
Subsidence is highly geographically variable in the UK. Blocks on shrink-swell clay soils — much of London (particularly south, west, and Thames-side), Essex, Kent, Surrey, parts of Hampshire and Wiltshire — face materially higher subsidence exposure than blocks on stable strata. Period buildings on shallow foundations, blocks affected by nearby tree root systems, and buildings adjacent to recent excavations all carry elevated risk. Claim values are high, particularly where underpinning or partial reconstruction is needed.
Tree management programme — pruning or removal of trees identified as material risk by a competent arboricultural assessment; structural monitoring where any sign of movement (crack monitoring, level surveys); drainage condition surveys (defective drains are a major subsidence trigger as water alters soil moisture); maintenance of gutters and rainwater goods to prevent soil saturation around foundations; engagement with neighbouring development to manage excavation risk.
Subsidence is a standard buildings peril. The subsidence excess is typically £1,000 or more, higher than other perils, reflecting both severity and the long-tail nature of claims. Postcode loading is significant — insurer underwriting models include detailed subsidence risk maps. Following a subsidence claim, ongoing monitoring conditions and significantly elevated excesses (£5,000+) are common. Insurer continuity matters more for subsidence than other perils — switching insurer mid-subsidence-event can create dispute over which insurer is responsible.
15. Risk 5: Property owners' liability — communal areas
Property Owners' Liability — The Everyday Risk
Communal areas in blocks of flats are the freeholder/RTM/RMC's occupier responsibility under the Occupiers' Liability Act 1957 (visitors) and the Occupiers' Liability Act 1984 (trespassers). Common claim drivers: slips on wet floors in lobbies; trips on damaged stair carpets, loose tiles, or worn entrance matting; falls down poorly-lit communal stairs; lift incidents; falling debris from external walls or balconies; injuries from defective communal equipment (intercoms, gates, automatic doors). Serious injuries from falls can produce very high-value claims.
Documented communal area inspection regime — at minimum quarterly, ideally monthly visual checks; cleaning contractor with adequate own insurance and contractual indemnity; wet floor signage protocol; lighting adequacy in stairs, corridors, and external paths; lift maintenance under contract with documented response times; external wall and balcony inspections — particularly important for period buildings or properties with rendered external walls; tree management for any communal grounds; documented response to leaseholder hazard reports.
Property Owners' Liability £5m typically standard, £10m where required by contract or where any commercial element exists. Defence costs are typically included within the limit (or additional on better policies). Documented inspection regime is the primary claim defence — the courts have consistently held that "reasonable" inspection systems are the test of occupier care. Without documented inspection records, claim defence is materially harder.
16. Risk 6: Loss of rent and alternative accommodation
Loss of Rent and Alternative Accommodation — The Forgotten Exposure
When a major insured event renders flats uninhabitable — fire, severe flood, structural failure — the freeholder, RTM or RMC may have contractual obligations under the lease to provide alternative accommodation, or leaseholders may withhold rent (where the lease so provides) pending reinstatement. For buy-to-let leaseholders, the loss of rental income is a direct loss. Loss of Rent / Alternative Accommodation cover under the block policy responds — but only to the limit and period specified. Many policies default to 12 months; reinstatement of a major fire-damaged block can take well beyond 12 months once statutory consents, design, tender and construction are included.
Period limit set realistically against actual reinstatement timeframes for the block type — 24 months for standard modern blocks, 36+ months for period, heritage, or complex buildings; financial limit set against current market rents or alternative accommodation costs (uplifted annually); review at every renewal as rents move; documented inventory of leaseholder rent levels where applicable (helps quantify the limit).
Buildings policy extension responding to loss of rent or actual reasonable cost of alternative accommodation where leaseholders are displaced. The cover is triggered by the same insured event that triggers the buildings claim. Period is the critical variable — under-specifying period creates a coverage gap during the back end of reinstatement. Insurers vary: some offer "actual loss until reinstatement complete" with no period cap; many cap at 24 or 36 months. Specialist placement secures appropriate periods.
17. Risk 7: Leaseholder Tribunal challenge and FCA non-compliance
Leaseholder Challenge — The New Regulatory Exposure
The combination of FCA leaseholder-as-customer rules, expanded LTA 1985 information rights, and the LFRA 2024 framework has materially increased the rate of leaseholder challenges to block insurance arrangements. Common challenge themes in 2026: insurance premium reasonableness (Section 19 LTA 1985); commission disclosure failures (FCA ICOBS 6A.7); reinstatement value adequacy (where underinsurance penalty has affected a claim); managing agent fees including insurance-related fees post-LFRA 2024. Outcomes range from premium recovery limitations and Tribunal orders to FCA enforcement against brokers where compliance failures are systemic.
Documented annual market test or 2-3 year retender process with at least 2 alternative quotes considered; full FCA-aligned commission disclosure at every renewal to all leaseholders; current RICS Reinstatement Cost Assessment; clear separation of broker commission, managing agent insurance fee (post-LFRA 2024), and other service charge items; section 30A response procedure in place to handle leaseholder information requests within statutory timeframes; pre-LFRA 2024 permitted insurance fees regime transition plan if managing agent currently receives commission.
Legal Expenses with leaseholder dispute and First-tier Tribunal scope responds to defence costs. The fines and Tribunal orders themselves are not insurable, but defence costs for a contested Tribunal case can be substantial and are insurable. D&O cover for RTM and RMC directors responds to personal liability claims arising from procurement decisions. The underlying placement discipline (RCA, market test, FCA disclosure) is the primary defence; insurance covers the cost of defending where the discipline is challenged.
18. What drives the cost of block of flats insurance in 2026?
UK block of flats insurance pricing in 2026 reflects the Grenfell-era underwriting tightening, escape of water claims inflation, reinstatement cost growth, and the new regulatory framework. Indicative annual premium ranges per flat, drawn from our own placement experience — they are not quotations and every block is rated on its own facts:
| Block Profile | Indicative Annual Premium Per Flat 2026 |
|---|---|
| Small modern block — 4-8 flats, 2-3 storeys, standard construction, no claims | £280-£500 per flat |
| Mid-sized modern block — 10-30 flats, 3-5 storeys, standard construction | £350-£700 per flat |
| Period conversion — 4-15 flats, pre-1940 construction, ageing pipework | £450-£900 per flat |
| Larger purpose-built block — 30-80 flats, lifts, communal facilities | £500-£1,200 per flat |
| High-rise compliant EWS1 — above 11m, A-rated EWS1, no remediation needed | £700-£1,800 per flat |
| High-rise B-rated / cladding remediation underway | £1,200-£3,500+ per flat (specialist placement) |
| Heritage / listed block — specialist materials, higher rebuild cost | £600-£1,500+ per flat |
The factors below drive both insurance premium and overall risk management investment. Rating impact within each profile band is typically larger than the differential between profile bands — meaning a well-managed period conversion with good claims and full documentation can cost less than a poorly-managed modern block with claims and no RCA.
| Rating Factor | Impact on Premium | What You Can Do |
|---|---|---|
| Construction type and age | Pre-1900 stock, timber-framed, flat-roofed: material loadings | Document construction; specialist placement for non-standard |
| Building height (sub-11m vs above) | Above 11m triggers BSA framework; materially different rating | EWS1 certificate essential; full BSA documentation pack |
| Cladding type and EWS1 status | A1-A3 or B1: standard rating; B2: heavy loadings or refusal | Engage developer/government scheme for remediation funding |
| Sum insured / reinstatement value accuracy | Underinsurance triggers average clause; correct values may reduce premium | RICS Reinstatement Cost Assessment every 3-5 years |
| Escape of water claims experience | Repeat claims: loadings, then conditions and higher excesses | Leak detection installation, pipework upgrade, lease covenant updates |
| Fire safety standards | Sprinklers, modern fire alarms and fire doors improve rating | Annual FRA; engagement with Fire Safety (England) Regulations 2022 |
| Security measures | Controlled entry, CCTV and alarms improve rating | Document at submission; maintain consistently |
| Postcode (subsidence, flood, theft) | Material postcode-based loadings or excess uplifts | Detailed postcode submission with mitigations |
| Excess level | A higher excess reduces premium | Match excess to block's financial capacity |
| Management quality (RTM/RMC vs professional) | Professional management modest reduction; documented RTM strong | Documented procedures; minutes; clear procurement |
| Number of years with current insurer | Continuity can help, but market-test regularly | Balance continuity vs market testing every 2-3 years |
| Commission structure (transitioning under LFRA 2024) | Lower commission = lower premium; permitted fee model once LFRA 2024 is commenced | Transparent permitted insurance fee aligned to actual work |
19. Example claims and how to manage them
The three scenarios below are illustrative composites drawn from the kinds of claims seen in this sector. They are not real cases, and the figures are realistic rather than actual.
Claim — Escape of Water Cascade, £87,500 Settlement
A 24-flat mid-rise purpose-built block experienced a flexible washing machine hose burst in a fifth-floor flat over a weekend when the tenant was away. Water ran for approximately 36 hours before being noticed by ground-floor leaseholders. Damage extended across 8 flats vertically and laterally — ruined plasterboard ceilings, decorations, flooring, kitchen units, and electrical systems. The flats were uninhabitable for periods ranging from 4 to 14 weeks. The block had no leak detection system and no communal water shut-off arrangement; the flexible hose was a known weak point at over 8 years old.
The buildings policy responded. Total settlement: £87,500 (reinstatement of plasterboard, decorations, flooring across 8 flats; £14,500 trace and access through cavity routes; £18,200 alternative accommodation for displaced leaseholders during reinstatement). Defence costs: minimal — claim was straightforward. The RMC's £500 excess applied per flat affected, totalling £4,000 of out-of-pocket costs across the eight flats.
Post-claim renewal: premium uplift 18% and the insurer imposed conditions — mandatory installation of communal water shut-off valve within 6 months; recommendation for leak detection on main risers; lease covenant amendment recommendation for tenant flexible hose replacement at 5 years. The RMC implemented all three. At the following renewal, premium returned to baseline.
The lesson: escape of water is the dominant claim category for blocks and the structural dynamics of multi-storey buildings make a single small leak into a major multi-flat claim. The small cost of replacing a flexible hose would have prevented an £87,500 claim. The £2,500 cost of communal shut-off plus leak detection would have substantially reduced damage. Insurance responded but the operational discipline is the real defence.
Claim — Underinsurance Average Clause, £1.4m Shortfall
An RTM company managing a 12-flat Edwardian conversion had not commissioned a Reinstatement Cost Assessment since the formation of the RTM nine years earlier. The original valuation had been £1.8m; renewal documentation had carried the same figure with modest inflation uplifts to £2.2m by the time of the claim. A fire in a third-floor flat spread to the roof structure and caused significant water damage from firefighting. Total reinstatement cost: £3.6m including specialist period materials, professional fees, debris removal, and statutory uplift to current building regulations.
The insurer instructed a RICS valuation post-incident which confirmed reinstatement at £3.6m. The declared value of £2.2m represented 61% of actual reinstatement. The average clause applied: claim settlement was reduced proportionally to 61% of the £3.6m loss = £2.196m. Net shortfall: approximately £1.4m that the insurer would not pay, leaving the RTM to fund it. Leaseholders challenged the service charge demands for the period covering the underinsured shortfall, citing breach of RTM director duties.
The RTM directors faced personal liability claims from leaseholders for the procurement failure. Their D&O policy (purchased belatedly two years earlier on broker advice) responded for defence costs of £38,000 and settlement of £85,000 split across three directors. Without D&O, the directors would have faced personal financial exposure of approximately £28,000 each.
Post-claim impact: the RTM commissioned an immediate RICS RCA, restructured the broker arrangement, retendered the placement, and instituted annual RCA inflation uplifts. The replacement policy declared £3.6m as opening reinstatement with index-linked uplift. Premium increased 35% reflecting the declared value increase, but the protection was actually adequate for the first time in nine years.
The lesson: underinsurance is the silent killer of UK block of flats insurance. RCA every 3-5 years is the minimum discipline. D&O cover for volunteer RTM directors is functionally essential where procurement decisions carry personal liability risk.
Claim — Cladding Remediation Period and Insurance Gap, £215,000 Cost Bridging
A 14-storey early-2000s residential block was identified as having B2-rated HPL cladding requiring full remediation. The developer had ceased trading. The block successfully applied to the Building Safety Fund for remediation funding. During the 18-month remediation period, mainstream buildings insurers withdrew or imposed B2-rated terms with 110% loading and increased excesses. The RMC managing the block found itself with a quotation 240% higher than the previous year, with significant cover restrictions including a contamination sub-limit and reduced loss of rent period.
Specialist Lloyd's placement via a brokerage with direct market access secured a structured solution: a primary layer with mainstream insurer at reduced limit (£8m) covering all non-cladding-related perils with full standard excess; an excess layer with Lloyd's syndicate covering above £8m up to full reinstatement; a separate facility for terrorism cover; documented engagement evidence with Building Safety Fund to maintain underwriter confidence in remediation progress.
Premium during remediation period: £215,000 (vs previous year £125,000). The £90,000 uplift was charged to leaseholders through service charge. Three leaseholders challenged the reasonableness at First-tier Tribunal. The RMC successfully defended the challenge with evidence of: market testing demonstrating no available alternative at lower price; engagement with three brokers including specialist Lloyd's access; documented Building Safety Fund engagement; structured layered placement evidencing best available terms.
Following completion of remediation 16 months later, the block obtained A1-rated EWS1. Premium returned to standard mainstream rating with a 12% residual loading reflecting the recent history. Total bridging cost across the remediation period: approximately £145,000 above standard rating, all recoverable from leaseholders with documented service charge demands and successful defence of Tribunal challenge.
The lesson: cladding-affected blocks during remediation create acute insurance challenges that mainstream markets cannot address. Specialist Lloyd's placement, documented Building Safety Fund engagement, and a defensible procurement process protect both the cover position and the service charge recovery. The Tribunal challenge defence pack — evidence of market testing, broker shopping, and best-available-terms — is the discipline that turns a difficult cover into a defensible cost.
Claims Management Steps
How to respond to a block of flats insurance incident — the steps below are critical given the multi-stakeholder structure (leaseholders, lender, insurer, freeholder) and the regulatory environment around block insurance in 2026:
- Make the site safe and protect persons first. Standard response. Evacuate where necessary; engage fire and rescue, ambulance, police as required; secure the premises against further damage and unauthorised entry.
- Notify your insurer immediately for any potential claim. Block of flats incidents often engage multiple policies and stakeholders (leaseholder contents, individual lender, freeholder, RTM/RMC, managing agent). Single notification triggers coordinated response. Threshold is "may give rise to a claim" — much lower than "formal claim received".
- Preserve all documentation rigorously. Cause of incident; photographs before, during, after; inventory of affected flats; leaseholder communications; contractor records; cleanup contractor invoices; alternative accommodation arrangements. The documentation pack supports both the immediate claim and any leaseholder service charge challenges that follow.
- Communicate with leaseholders proactively and in writing. Leaseholders affected by the incident have rights and interests. Clear, prompt, written communication about the situation, the response, and the timetable reduces the risk of subsequent service charge disputes. Document everything.
- Engage the insurer's loss adjuster constructively. Major losses trigger loss adjuster appointment within 24-48 hours. Cooperation, prompt documentation, and engagement with the adjuster's questions shortens claim duration and supports settlement. Document all interactions.
- Manage alternative accommodation and loss of rent with insurer authority. Where flats are uninhabitable, the loss of rent / alternative accommodation cover responds — but typically with insurer pre-authorisation of arrangements. Don't commit to long-term arrangements without insurer engagement.
- Document reinstatement timeline and any building regulation uplifts. Modern building regulations may require uplifts during reinstatement (insulation standards, fire safety provisions, accessibility). These are often covered by buildings policy "current building regulations" extensions — but require documentation.
- Review insurance arrangement immediately after settlement. Major claims typically trigger renewal repercussions including loadings, excess uplifts, or conditions. Use the post-claim period to commission RCA, implement risk management improvements, and review broker placement.
Glossary of block of flats insurance terms
- Block of Flats Insurance
- A single buildings insurance policy covering an entire residential block — the structure, communal areas, and core liability exposures — rather than individual flats separately. Sometimes called block insurance or freeholder insurance.

- A RICS-style valuation of the cost to rebuild a property to its existing form and standard, including professional fees, debris removal, and statutory uplifts. The basis for the declared sum insured. Distinct from market value.
- Average Clause
- The contractual provision in most buildings policies that reduces claim settlement proportionally where the declared sum insured falls below actual reinstatement value at the time of loss. Triggers automatically on underinsurance.
- Freeholder
- The owner of the freehold title to a block of flats. Contractually obliged under most leases to insure the structure of the building, recovered through the service charge.
- Right to Manage (RTM) Company
- A company formed by leaseholders under the Commonhold and Leasehold Reform Act 2002 to take over management functions from the freeholder, including buildings insurance procurement.
- Resident Management Company (RMC)
- A management company built into the lease structure of a development from outset, typically owned by leaseholders, with contractual responsibility for insurance, maintenance, and management.
- Managing Agent
- A professional firm appointed by a freeholder, RTM, or RMC to handle day-to-day management including procurement of insurance. The agent acts on behalf of the principal; under FCA rules from 2023, commission received by agents must be disclosed to leaseholders.
- Building Safety Act 2022 (BSA)
- UK statute introduced following the Grenfell Tower fire. It gives qualifying leaseholders in buildings of 11 metres or 5 storeys and over protection from remediation costs under Schedule 8, and creates a new safety regime for higher-risk buildings of 18 metres or 7 storeys and over.
- Qualifying Leaseholder

- EWS1 (External Wall System) Certificate
- RICS valuation-driven certificate confirming the safety of external wall systems on residential buildings above 18 metres (and frequently required above 11 metres). Outcomes A1, A2, A3 and B1 need no remediation; B2 means remedial works are required.
- Leasehold and Freehold Reform Act 2024 (LFRA 2024)
- UK statute introducing major leasehold reforms, including sections 61 to 64, which will limit insurance-related charges to "permitted insurance fees" once commenced through secondary legislation (targeted for April 2026 and still awaited at the time of writing).
- Permitted Insurance Fee
- Under the LFRA 2024 framework, the regulated fee that replaces broker commission and managing agent insurance commission in the service charge — based on actual costs of arranging and managing insurance, with full leaseholder transparency.

- Trace and Access Cover
- Cover for the cost of locating the source of a leak (e.g. removing plaster, lifting floors) where damage requires investigation. Often a sub-limit; specialist placement secures adequate scope.
Frequently asked questions
Block of flats insurance is a single buildings insurance policy covering an entire residential block — the building structure, communal areas, and the core liability exposures of the freeholder, RTM, or RMC. Core covers in 2026: Buildings at full reinstatement value (fire, escape of water, storm, flood, subsidence, impact, malicious damage); Property Owners' Liability £5m-£10m for communal area injury and third-party damage; Loss of Rent / Alternative Accommodation for displaced leaseholders; Engineering Inspection where lifts or pressure systems present. Individual flat contents are not covered — that's the leaseholder's own contents policy.
The lease tells you who. In most cases the freeholder is contractually obliged to insure the structure and recover the cost through the service charge. Where leaseholders have formed a Right to Manage (RTM) company under the Commonhold and Leasehold Reform Act 2002, the RTM takes over management functions including insurance procurement. Where a Resident Management Company (RMC) is built into the lease, the RMC carries the duty. Managing agents acting on behalf of any of the above transact on the principal's behalf — but legal responsibility rests with whoever the lease names. Whoever buys is who is liable for underinsurance, FCA compliance, and Section 20 obligations.
From 31 December 2023, ICOBS 6A.7 of the FCA Handbook defines leaseholders as customers of multi-occupancy buildings insurance. Insurers and brokers must act in leaseholders' best interests, manage conflicts so remuneration does not drive the choice of policy, and disclose the commission paid to freeholders, managing agents, and third parties. The disclosure must be provided "as soon as reasonably practicable" after policy inception and at every renewal. The Leasehold and Freehold Reform Act 2024 will go further once sections 61 to 64 are commenced — replacing commission recoverable through service charges with transparent "permitted insurance fees". Commencement was targeted for April 2026 and is still awaited.
Indicative 2026 annual premiums per flat: small modern block £280-£500; mid-sized modern block £350-£700; period conversion £450-£900; larger purpose-built £500-£1,200; high-rise compliant EWS1 £700-£1,800; high-rise B-rated cladding £1,200-£3,500+; heritage/listed £600-£1,500+. Pricing depends on construction type and age, building height (above/below 11m), cladding status, sum insured accuracy, claims history, fire safety standards, security, postcode, and excess level. These are indicative ranges from our own placements, not quotations. For a quote on your block, see our block of flats insurance page.
The Building Safety Act 2022 is the UK statute introduced following the Grenfell Tower fire creating safety duties for buildings above 11 metres or 5 storeys. Key effects on block insurance: qualifying leaseholders protected from cladding remediation costs under Schedule 8; EWS1 certificates have become de facto requirement for insurer acceptance of cladded buildings; higher-risk buildings (18 metres or 7 storeys and over) need a safety case report, which underwriters increasingly ask to see; remediation funding comes via developer obligations, the Building Safety Fund (18m and over) and the Cladding Safety Scheme (11-18m). The Act fundamentally changed the rating of any block above 11m and created a structured remediation framework for unsafe cladding.
Escape of water dominates block of flats claims because of structural physics: a single leak in an upper flat cascades vertically through floor structures and spreads laterally through party walls, simultaneously damaging multiple flats. A single burst flexible hose can damage several flats — plasterboard, decorations, flooring, sometimes electrical and structural elements — and severe multi-flat cascades can run well into six figures. Ageing pipework in period blocks, flexible hoses past their service life, and absence of communal water shut-off systems make the problem worse. Operational mitigations (leak detection, shut-off valves, lease covenants on hose replacement) materially reduce frequency and severity.
Underinsurance is where the declared sum insured falls below actual reinstatement cost at the time of loss. The "average clause" reduces claim settlement proportionally — a block insured for £4m with actual reinstatement of £6m faces a 33% reduction on every claim, even small ones. Industry surveys have repeatedly found a large share of UK commercial properties underinsured, and blocks of flats are particularly exposed because rebuild values rarely keep pace with construction cost inflation. The fix is straightforward: commission a RICS Reinstatement Cost Assessment every 3-5 years, uplift annually for construction inflation, and review after any material building works. The cost of an RCA is small against the potential claim shortfall.
Yes — and it's frequently overlooked. RTM and RMC directors are typically volunteer leaseholders, often unpaid, taking on procurement decisions including insurance, contractors, and major works. Under company law and the lease structure, they carry personal liability for those decisions. Where a procurement decision proves negligent (e.g. allowing material underinsurance to develop, failing to retender, accepting undisclosed commission), affected leaseholders can bring personal claims against the directors. D&O cover responds to defence costs and settlements. Limits of £1m-£5m are common for RTM and RMC companies. Functionally essential given the 2026 regulatory environment around FCA disclosure and LFRA 2024 commission rules.
Section 20 applies to "qualifying long-term agreements" (QLTAs) — agreements for the provision of services lasting more than 12 months where cost to any single leaseholder will exceed £100 per year. Annual block insurance is not a QLTA, which is why most UK block insurance is renewed annually. Multi-year deals offered for premium reduction can trigger QLTA status requiring full Section 20 consultation — Notice of Intention, leaseholder observations, at least two estimates, Notice of Proposal, final decision. Failure to consult limits recovery from leaseholders to £100 per leaseholder per year on unconsulted amount. Most freeholders/RTMs/RMCs deliberately avoid multi-year insurance to sidestep Section 20 — though it remains an option with proper procedure.
Yes. Under Section 19 of the Landlord and Tenant Act 1985, service charges (including insurance premiums recovered) must be reasonably incurred and the works of a reasonable standard. Leaseholders can apply to the First-tier Tribunal (Property Chamber) to challenge reasonableness, and the burden of proving reasonableness falls on the landlord. The Tribunal can order proportional refund where premium is found unreasonable. Defence requires documented evidence of: market testing (typically 2+ alternative quotes within last 2-3 years); FCA-compliant commission disclosure; current Reinstatement Cost Assessment; specialist broker engagement appropriate to the block profile. Operators with auto-renewal arrangements and no market testing are increasingly exposed to successful challenges.
The working standard for 2026 is every 2-3 years at minimum, with annual benchmark/light retender as best practice. The Tribunal expectation is documented evidence that the placement was selected on customer value at a reasonable price, which requires periodic market testing. Auto-renewing for several consecutive years without market testing leaves the landlord with little evidence to defend a reasonableness challenge. The cost of a retender is modest — a specialist broker can run a market test efficiently — and any continuity benefit from the existing insurer should be weighed against what the wider market offers.
Look for brokers with specific experience in block of flats, freeholder, and RTM/RMC placements evidenced by: specialist articles or guides on multi-occupancy buildings insurance; willingness to discuss FCA ICOBS 6A.7 disclosure framework and LFRA 2024 permitted insurance fees regime transition in detail; access to Lloyd's market and specialist MGAs for cladding-affected and high-rise blocks; a listing on the FCA Financial Services Register and a documented track record. Avoid brokers offering generic property cover without discussing block-specific issues; brokers unable to handle EWS1 submissions; brokers not asking about RCA, claims experience, or commission structure at proposal.
