Fire Door Installer and Inspector Insurance UK 2026
Why does a fire door installer or inspector need specialist insurance?
The scale of the problem is measured. Of more than 100,000 fire doors inspected by Fire Door Inspection Scheme approved inspectors in 2021, 75% did not meet the required standard: 77% of the failures had excessive gaps between door and frame, 37% had smoke-seal faults and 31% had been installed so poorly they were never fire-resistant. Fire and rescue services carried out 51,020 audits in 2024/25 and found only 58% satisfactory, issuing 1,728 enforcement notices and 959 prohibition notices. The Grenfell Tower Inquiry found that flat entrance doors rated for 30 minutes failed in fifteen. Around three million fire doors are sold in the UK each year, and a large proportion of them will be installed by a business whose insurance was arranged for carpentry.
The regulatory shape is now settled. Regulation 10 of the 2022 Regulations requires the responsible person of a multi-occupied residential building over 11 metres to check common-parts fire doors quarterly and flat entrance doors annually on a best-endeavours basis, and regulation 9 requires residents to be told why fire doors matter; the Building Safety Act's higher-risk building regime puts every one of those checks into the golden thread. Responsible persons are contracting the checks out to fire door inspection businesses, the same businesses are being asked to remediate what they find, and the fire risk assessor is relying on both. Each of those three roles — supplier, installer, inspector — is insured differently, and most fire door businesses do all three.
This guide sets out why a certified leaf is not a certified door, the three roles and their exposures, the exclusions and what removes them, what regulation 10 requires and who carries the liability, the standards a claimant measures the work against, why certification comes first, the limitation period and run-off, the contract and report terms that matter, and how a fire door business is placed. It sits with our passive fire protection contractor guide and our fire risk assessor PI guide in the Building Safety Act cluster, and connects to our contractors combined insurance page, where most of these enquiries begin.
Key facts at a glance
- 75% of fire doors inspected failed in the FDIS 2021 data — 77% of failures for excessive gaps, 37% for seal faults, 31% for installation so poor the door was never fire-resistant. The installer is the most common cause.
- A fire door is an assembly, not a leaf. The test evidence covers a specific leaf, frame, seals, ironmongery, glazing and gap configuration. Change any element and the certification does not apply; the installer becomes the producer of an untested door.
- The efficacy exclusion removes the only claim. Standard contractors' liability excludes loss from a fire protection product failing to perform. A fire door only causes loss by failing to hold. Deletion for certified activities is the core of the placement.
- The inspection report is professional indemnity. A regulation 10 check, an FDIS survey or a "fit for purpose" statement is an opinion relied on by the responsible person and the regulator. It is uninsured without PI with the fire safety exclusion deleted.
- Regulation 10 made fire door checks a recurring legal duty — quarterly for common-parts doors, annually for flat entrance doors, in residential buildings over 11 metres, since 23 January 2023. Businesses contracted to do them own the adequacy of the check.
- Flat entrance doors are in every residential FRA since the Fire Safety Act 2021 — and out of the leaseholder's control, which is why responsible persons are commissioning surveys and replacements at scale.
- Liability runs fifteen years for dwelling work under section 135 of the Building Safety Act 2022, thirty years retrospectively. Fire door work in flats is dwelling work. Run-off must match.
How does The Insurability Framework™ apply to fire door businesses?
Placing a fire door installer, maintainer or inspector in a market that has spent eight years excluding fire safety is exactly what the Insurability Framework was built for.
The Insurability Framework — applied to fire door businesses
Four pillars, one method: separate the door you can evidence from the sector's failure rate, and price the evidence.
Underwriter Intelligence
Fire door underwriters ask five questions: is the business certified as an installer, a maintainer or an inspector — and under which scheme and scope; does it install complete certified doorsets or assemble doors from components; does it hold the test evidence and the manufacturer's installation instructions for every door it fits; does it sign reports, and on what template; and what share of its work is flat entrance doors in buildings over 11 metres? We answer all five with the certificates, the doorset register and the report template, so the business is priced on its process rather than on the 75% failure rate.
Difficult Risk Expertise
Package joinery and maintenance markets rate fire doors as carpentry and leave the efficacy exclusion in place; package PI does not exist for inspection reports. A small number of Lloyd's syndicates and specialist MGAs with fire protection appetite delete the exclusion for certified scope, write PI for the inspection and survey work with the fire safety exclusion removed, and offer run-off that can actually be bought.
Risk Assessment
We find what the proposal form misses: the assembled-on-site doors that carry no certification; the "supply and fit" contract that makes the installer the producer under the Consumer Protection Act; the quarterly check signed on a tick-sheet with no defect reported; the leaseholder's own door replaced without a doorset certificate; the maintenance contract that promises compliance; and the fifteen-year tail on every flat entrance door.
Claims Advocacy
A claim against a fire door business arrives after a fire, an audit or a fire risk assessor's survey, alongside a responsible person's pass-down, an enforcement notice and a possible Building Safety Regulator enquiry. We coordinate the liability adjuster, the PI panel and the legal expenses solicitor so the business speaks with one voice — and has a broker who has read a doorset test report, not a helpline.
Why does installing a certified door leaf not give you a certified fire door?
| Element | What the test evidence and BS 8214 specify | Common installation failure | Who carries it |
|---|---|---|---|
| Leaf | Tested leaf by named manufacturer, thickness and core; permanent label or plug; only trimming within the manufacturer's limits | Leaf planed beyond the permitted margin; label removed; leaf of unknown provenance | Installer |
| Frame | Material, section and density within the scope of application; fixed at specified centres; packing and gap-filling to the evidence | Certified leaf hung in an existing softwood frame of unknown density; frame fixed with insufficient fixings | Installer |
| Gaps | Typically 2–4 mm at head and sides, up to 10 mm at threshold (less where smoke control is required), per the evidence | 77% of failed doors in the FDIS data — gaps exceeding the limit through poor hanging or building movement | Installer; maintainer |
| Intumescent and smoke seals | Type, size and position as tested; continuous; combined or separate smoke seals where required | Seals missing, painted over, cut short or of a different type; 37% of failures | Installer; maintainer |
| Hinges | Number, grade (typically CE/UKCA-marked to BS EN 1935, grade 11–13), fixings and intumescent pads as tested | Two hinges instead of three; non-fire-rated hinges; no pads | Installer |
| Closer | Controlled door closing device to BS EN 1154, power size matched to the leaf; must close from any angle and latch | Closer disconnected or removed; wrong power size; door held open; fails to latch | Installer; maintainer; occupier |
| Latch and lock | Fire-rated to BS EN 12209 with intumescent protection; keeps the door closed in a fire | Non-rated lock fitted; no intumescent kit; latch removed for convenience | Installer |
| Glazing | Fire-rated glass, beading and intumescent glazing system as tested; apertures within the scope of application | Vision panel cut on site outside scope; wrong glass or beads | Installer |
| Threshold and floor | Gap and drop-down seal as required; combustible floor coverings not run under | Carpet fitted after installation raising the threshold gap; missing drop seal | Installer; occupier |
The insurance consequence is structural. An installer fitting complete certified doorsets — leaf, frame and ironmongery supplied as a tested unit under a scheme such as Certifire, BM TRADA Q-Mark or BWF Fire Door Alliance — is installing a product with a manufacturer behind it, and its liability is for the installation. An installer assembling doors from components is the producer of the assembly under the Consumer Protection Act 1987 and the manufacturer of nothing under any certification scheme; its liability is for the door. Underwriters rate the two differently, and a business that does both needs its policy to say so. Our product recall insurance guide covers what happens when a batch of doorsets is found not to perform.
Why are supplying, installing and inspecting fire doors three different insurance risks?
| Role | Legal basis of liability | Who claims | Typical consequence of error | Policy that responds |
|---|---|---|---|---|
| Supplier / manufacturer of doorsets | Consumer Protection Act 1987 Part I strict liability; Construction Products Regulations (UKCA/CE to BS EN 16034 for external doorsets); contract; GPSR 2005 | Building owner, occupier, injured person; OPSS or Trading Standards for non-compliant products | Injury or damage when the door fails; recall or withdrawal of a batch; enforcement notice | Products liability with efficacy deleted; product recall cover for the batch |
| Installer | Contract (reasonable skill and care, or fitness for purpose if agreed); negligence; Defective Premises Act 1972 for dwellings; Building Regulations compliance | Client; building owner; subsequent owners under DPA; occupiers injured; insurers in subrogation | Fire spreads through a door that did not hold; enforcement notice on the responsible person passed down; cost of re-hanging or replacement | Public liability with efficacy deleted (third-party loss); contractors' PI for specification decisions; rectification of own work is the business's |
| Maintainer (regulation 10 checks and remedial work) | Contract; negligence; the responsible person's duty delegated but not transferred | Responsible person; fire and rescue service via enforcement; occupiers | Defect missed at a quarterly check and a fire follows; door "repaired" outside the evidence; check signed without inspection | PI for the check and the report; liability with efficacy deleted for the remedial work |
| Inspector / surveyor (FDIS, condition surveys, compliance reports) | Contract; negligence; negligent misstatement to third parties who rely on the report | Responsible person; fire risk assessor; Building Safety Regulator via the golden thread; purchasers and lenders where reports are relied on | Door passed that fails in a fire; portfolio survey that understates replacement need; report relied on in a safety case | Professional indemnity with the fire safety exclusion deleted, limit sized to the buildings surveyed |
The practical trap is the business that started as a joinery contractor, added "fire door maintenance" when regulation 10 created the demand, and now signs quarterly check reports for a housing association's portfolio on the same policy it bought to hang doors. The policy has no PI section; the liability section has the efficacy exclusion; and the quarterly report — signed on a tick-sheet — is the document the fire and rescue service reads after the fire. Our fire and safety business insurance guide covers the installation side of active systems; this guide covers the door.
Which exclusions sit on a fire door business's policies — and what removes them?
| Exclusion | Policy it sits on | What it removes for a fire door business | What removes it |
|---|---|---|---|
| Efficacy exclusion | Public and products liability | Any claim arising from a fire door failing to perform its fire-resisting or smoke-control function — the only claim the business will face after a fire | Third-party installer certification (Q-Mark, FIRAS, IFC) with scope matched; doorset register; manufacturer instructions on file; deletion written to the certified scope |
| Professional-advice exclusion | Public liability | Any claim arising from advice, design, specification, survey or report given for a fee — the inspection report, the condition survey, the "fit for purpose" statement | Not removable — the answer is a PI policy alongside |
| Fire safety exclusion | Professional indemnity | Any claim arising from fire safety assessment, inspection or advice — the whole of the inspection business | FDIS or equivalent inspector certification; report template with scope, method and limitations; sample reports; competence records; deleted for declared inspection activities |
| Product guarantee exclusion | Products liability | Liability for the door failing to perform as sold — the cost of replacing it, as opposed to the damage it caused | Not removable on liability cover; contractual and recall exposure sits with the business or with product recall cover |
| Recall exclusion | Products liability | The cost of withdrawing or recalling a batch of doorsets found not to perform | Product recall insurance bought before the defect is known |
| Contractual liability exclusion | Liability and PI | Liability assumed under contract beyond what would exist at law — compliance guarantees, fitness-for-purpose promises, indemnities in maintenance contracts | Contract terms on a reasonable-skill-and-care basis; no warranties of outcome |
| Hazardous-activity referral | Package liability | "Installation of fire protection" listed as an activity requiring referral or excluded outright | Placement with a specialist market that writes fire protection as a declared activity |
The most dangerous of the seven is the professional-advice exclusion, because it is invisible to a business that has never read past the schedule. A joinery liability policy does not say "inspection reports excluded"; it says advice given for a fee is excluded, and leaves the business to discover, after the fire, that the report it signed every quarter for three years was never insured. Our guide to choosing a professional indemnity broker covers why the activities schedule matters more than the limit.
What do the regulation 10 quarterly and annual checks actually require — and who carries the liability?
The government's fire door guidance under the Regulations describes what a check involves: that the door closes fully and latches from any position, that the closer works, that the intumescent and smoke seals are present and undamaged, that the hinges are secure and the gaps within limits, that the glazing is intact and that the door has not been altered. It does not require a certified inspector, which is why responsible persons often start with their own caretakers — and why, when a fire risk assessor or a fire and rescue service audit finds the checks inadequate, they contract them out to a fire door business. That business then carries the professional liability the responsible person could not do without.
Three shapes of claim follow. The missed defect: a quarterly check records a common-parts door as satisfactory; the door's closer had been disconnected; a fire spreads into the escape route; the responsible person's insurer pays and recovers from the inspector. The unrecorded recommendation: the check found the flat entrance door gaps excessive but the report said "monitor"; the responsible person did nothing; the fire and rescue service serves an enforcement notice; the responsible person claims the cost of the works and the disruption. The reliance beyond the client: the inspection report was placed in the building's golden thread and relied on in the accountable person's safety case; the Building Safety Regulator's review finds the doors non-compliant; the accountable person claims the cost of the certificate delay. In each case the inspection business's defence is its report — what it inspected, how, what it found, what it recommended — and its PI policy is what funds that defence. Our block of flats insurance guide covers the responsible person's side of the same regulation.

Which laws and standards define what a fire door must be — and what a claimant will measure your work against?
| Instrument | What it requires | Who it binds | Insurance relevance |
|---|---|---|---|
| Building Regulations 2010 and Approved Document B | Fire doors in compartment walls and protected routes to achieve stated fire resistance (FD30, FD60 etc.) and, where required, smoke control (S); self-closing devices; regulation 7 workmanship; regulation 38 fire safety information at handover | The person carrying out the work; the building control body checks | Installation not meeting ADB is a breach of the Building Regulations and, for dwellings, a Defective Premises Act claim |
| BS EN 1634-1 / BS 476-22 | Furnace test standards for fire resistance of door assemblies; classification to BS EN 13501-2 (E, EI, EW) or FD ratings | The manufacturer's evidence; the certification scheme's scope of application | Defines the assembly the installer must replicate; outside it, no evidence exists |
| BS 8214:2016 | Code of practice for fire door assemblies — installation, gaps, fixings, seals, ironmongery, maintenance | The installer and maintainer as good practice; the yardstick in litigation | The standard the claimant's expert cites against the installation record |
| BS EN 16034 and the Construction Products Regulations | Product standard for pedestrian doorsets with fire and smoke characteristics; UKCA/CE marking mandatory for external doorsets, voluntary for internal | The manufacturer and, for supply-and-fit, the supplier | Product compliance; OPSS and Trading Standards enforcement; products liability |
| Regulatory Reform (Fire Safety) Order 2005 | Responsible person to maintain fire doors (article 17) and assess risk (article 9); article 8 general fire precautions | The responsible person; contractors under article 5(3)–(4) where they have control | Enforcement and prosecution of the responsible person; recovery claims against the contractor |
| Fire Safety Act 2021 | Flat entrance doors and the structure and external walls within the scope of the Order for multi-occupied residential buildings | The responsible person | Every residential FRA now addresses flat entrance doors; replacement programmes follow |
| Fire Safety (England) Regulations 2022 — regs 9 and 10 | Fire door information to residents (all multi-occupied residential); quarterly common-parts and annual flat entrance door checks (over 11m) | The responsible person; delegated to contractors | The inspection business's professional liability for each check and report |
| Building Safety Act 2022 | Section 135 limitation (15/30 years DPA); ss.130–132 building liability orders; Part 4 golden thread; competence of dutyholders and their appointees | Everyone in the chain | The tail, the reach and the records |
| Consumer Protection Act 1987 Part I | Strict liability of producers — including anyone who assembles a door from components and supplies it — for damage caused by a defect | Manufacturers, own-branders, importers, site assemblers | Products liability with efficacy deleted; product recall |
The point for the fire door business is that none of these instruments is discretionary and all of them are documentary. The installation is measured against BS 8214 and the manufacturer's instructions by an expert with the installation record in one hand and the test evidence in the other; the inspection is measured against the regulation 10 guidance and the FDIS method with the report in one hand and the photographs of the door after the fire in the other. A business that keeps the record wins the argument or narrows the loss; a business that does not has nothing to show. Our HSE prosecution guide covers the parallel position for the responsible person's own insurance after enforcement.
Why do underwriters ask for Q-Mark, FIRAS, IFC or FDIS before anything else?
| Scheme | Who it certifies | What it evidences | What it means to the underwriter |
|---|---|---|---|
| BM TRADA Q-Mark fire door installation and maintenance schemes | Installers and maintainers of fire doors — company and operative level | Site audits, operative assessment, installation to manufacturer's instructions and BS 8214, maintenance to the evidence | The certificate most often asked for by name for fire door work; the efficacy deletion is written to its scope |
| FIRAS installer certification (fire doors scope) | Passive fire protection installers including fire door installation | Equivalent UKAS-accredited scheme; scope listed by activity | Accepted; scope must name fire doors |
| IFC Certification installer scheme | Fire door and passive fire protection installers | Equivalent scheme; company and operative assessment | Accepted as equivalent |
| Fire Door Inspection Scheme (FDIS) | Individual inspectors — diploma in fire doors and certificated inspector status | Knowledge and competence in fire door inspection; the methodology underwriters expect reports to follow | The primary evidence for PI with the fire safety exclusion deleted for inspection work |
| Certifire (Warringtonfire), Q-Mark doorset scheme, BWF Fire Door Alliance | Doorset and door leaf manufacturers | Product certification with a scope of application; label or plug on every door | Evidence that the products installed are certified; the scope of application defines what the installer may vary |
| LPCB LPS 1197 / LPS 1271 | Installers of fire doors (LPS 1197) and passive fire protection (LPS 1271) | Product-and-installer linkage under BRE Global | Strongest evidence where the client specifies LPCB-approved systems |
| Manufacturer approved-installer status | Installers trained by doorset manufacturers | Product-specific installation training and access to instructions | Supports the installation position; not a substitute for scheme certification |
Certification is also the boundary of the cover. A Q-Mark installer certificate does not evidence competence in inspection; an FDIS diploma does not evidence competence in installation; and a maintainer scope does not cover replacing a flat entrance door. Specialist markets delete the efficacy exclusion and the fire safety exclusion for the certified scope and retain them for everything else, so a business whose work has grown from installation into regulation 10 checks, or from checks into replacement programmes, needs the certificate scope extended and the policy endorsed before the first contract, not after. Our passive fire protection contractor guide covers the fire-stopping and compartmentation side of the same certification schemes.
How long does a fire door installer stay liable — and what does run-off cost?
The fire door business's liability clock has the same feature as every passive fire protection trade: the damage is a fire, and the fire may be years away. A flat entrance door hung in 2026 with a closer of the wrong power size causes no loss until the kitchen fire in 2033; the negligence period then runs from 2033, subject to the fifteen-year longstop from 2026; and the Defective Premises Act claim runs to 2041 regardless. The installation record, the doorset certificate and the handover pack — if they exist — are what the business defends itself with in 2033; the policy in force in 2033 is what pays.
The two bases behave differently at the end of the business. Liability is occurrence-based: the policy in force on the date of the fire responds, so a business that ceases trading and cancels its liability cover has no policy on the date of a future fire — products liability run-off, which specialist markets offer for installed work, is the answer. PI is claims-made: the policy in force when the claim is notified responds, so a claim on a 2026 inspection report arriving in 2031 is covered only by run-off. Specialist markets offer declining run-off to businesses they already insure with a clean record; a business that arrives at retirement uninsured, after a gap or after a decline, has few options. We budget run-off from the first placement for every fire door business, and for replacement programme contractors we plan fifteen years and record it in the succession plan. Our guide to professional indemnity run-off cover sets out the mechanics.
Which contract and report terms move a fire door business's risk outside its insurance?
| Term or document | What it does | Insurance effect | What to negotiate or change |
|---|---|---|---|
| Maintenance contract compliance guarantee | "The contractor shall ensure all fire doors comply with the Regulations" — an outcome obligation | Excluded by the contractual-liability exclusion on PI and liability; the guarantee sits with the business | Reasonable skill and care in carrying out the checks and remedial work; the responsible person's own duty acknowledged |
| Tick-sheet inspection report | Records "OK" or "defect" per door with no scope, method, measurements or limitations | Every "OK" is an unqualified statement the door is compliant; no defence when it fails | Template recording scope, method, each element checked, gap measurements, defects, action, doors not accessed, reliance restriction |
| Framework or principal contractor insurance clause | Requires "products liability including efficacy" or "PI covering fire safety" at stated limits | A non-matching policy is a breach from day one; the client's insurer looks to the contractor | Send to the broker before signing; match the policy or amend the clause |
| Supply-and-fit terms | The contractor supplies the doorset and installs it | Producer liability under the CPA for the doorset; installer liability for the work; both need efficacy deleted | Products liability declared; doorset certification evidenced; recall cover where volumes justify |
| Collateral warranty | Direct claim by funder, purchaser, tenant or management company | Each beneficiary a claimant on the same limit; fitness-for-purpose language uninsured | Limit beneficiaries; net contribution; reasonable skill and care only |
| Design or specification responsibility | Contractor surveys, specifies and selects the doorset for a replacement programme | Uninsured without design-and-construct PI with the fire safety exclusion deleted | PI matched to the scope; specification within certified doorset ranges; survey limitations stated |
| Uncapped indemnity | Indemnifies the client for all losses arising from the work without limit | Policy limit applies regardless; the excess is the business's | Cap at contract sum or insurance limit; exclude consequential loss |
| Reliance on reports by third parties | Reports placed in the golden thread, provided to purchasers, lenders or fire risk assessors | Negligent-misstatement claims from parties outside the contract | Reliance restricted to the instructing party; reliance letters only where insured and paid for |
Underwriters read the report template as closely as the certificate, because the template is the policy's exposure in miniature: a business that signs 1,400 unqualified "OK"s a quarter has written 5,600 warranties a year, and a business that records scope, method and limitations has written 5,600 defensible opinions. We review every fire door business's template and standard terms before the submission goes in.
What does fire door installer and inspector insurance cost — and what drives the premium?
| Rating factor | Why it moves the premium | What reduces it |
|---|---|---|
| Third-party certification and scope | The primary rating input; uncertified businesses are declined or heavily loaded; scope gaps mean partial deletion | Q-Mark / FIRAS / IFC / FDIS with scope matched to every activity |
| Activity mix | Commercial doorset installation rates lowest; residential and flat entrance doors higher; site assembly, supply-and-fit and inspection highest | Declare accurately; stop activities the business cannot evidence |
| Doorset discipline | Complete certified doorsets are a product with a manufacturer behind them; site assembly makes the business the producer | Doorset-only policy; register with certificates and labels |
| Portfolio and building types | Residential over 11m, higher-risk buildings, care and healthcare carry the highest consequence and longest tail | Portfolio profile with counts, heights and uses |
| Report controls | Tick-sheet reports are unqualified warranties; scoped templates are defensible opinions | Template with scope, method, measurements, limitations; sample reports |
| Inspection / remedial separation | Inspecting and then quoting for the remedy is priced as a conflict | Separation or disclosure; independent review |
| Contract terms and warranties | Compliance guarantees and uncapped indemnities increase severity | Standard terms and maintenance contracts reviewed; caps in place |
| Claims, circumstances and findings | A fire at a building the business worked in, or an audit or FRA finding its doors wanting, is rated whether or not a claim followed | Full disclosure with the outcome; show the process change |
| Operative competence and subcontracting | Labour-only operatives are the business's for competence and EL; bona fide subcontractors need their own certificate and cover | Operative register; subcontractor certificates evidenced |
| Handover and records | Regulation 38 packs and doorset registers reduce severity and shorten disputes | Handover pack per contract; fifteen-year retention |
| Continuity and retroactive date | Gaps leave installed doors and signed reports uninsured and signal instability | Continuous cover evidence; retroactive date to inception |
| Excess | Specialist markets trade a higher excess for a lower rate | Take a realistic excess the business can fund |
What do real fire door claims look like — and how should you manage one?
Case study 1 — The care home corridor doors and the leaf that was not a door (composite, illustrative)
Situation: A joinery contractor with £900,000 turnover replaced fourteen corridor doors in a 48-bed care home, fitting certified FD30S leaves into the existing hardwood frames, re-using the existing closers and fitting new seals from a builders' merchant. Eighteen months later a fire in a resident's bedroom breached the corridor door within nine minutes; the leaf had been planed 12 mm to fit the frame, the closer was under-powered and the seals were not the tested type. Two residents were hospitalised; the home was closed for four months. The operator's insurer paid £1.4m and pursued the contractor. The contractor's policy was a joinery package with the efficacy exclusion in place and no PI.
What we did: The contractor came to us after the claim, with its package insurer having declined under the efficacy exclusion and the professional-advice exclusion. We engaged coverage counsel; the decline was correct. The claim proceeded against the business uninsured. We then re-placed the business for the future: Q-Mark installer certification obtained over four months, a doorset-only policy adopted, a specialist liability placement with efficacy deleted for the certified scope, and £1m of contractors' PI.
Outcome: The subrogated claim settled at £520,000 with the contractor contributing £180,000 from its own resources and the balance from a director's personal assets and a settlement with the closer supplier; £74,000 of the contractor's own defence costs were unfunded. Re-placed at £9,800 liability against £3,100 expiring (+216%) and £2,400 PI. The business survived; the director's house was remortgaged.
Lessons: A certified leaf in an uncertified assembly is not a fire door, and a joinery policy is not fire door insurance. The £3,100 the contractor had been paying bought cover for everything except the only claim it would ever face.
Case study 2 — The quarterly check, the disconnected closer and the housing association (composite, illustrative)
Situation: A fire door maintenance business with £1.6m turnover held a three-year contract with a housing association for regulation 10 checks across 62 blocks. Its operatives recorded checks on a tablet tick-sheet. A common-parts door on a fourth-floor landing had had its closer arm removed by a resident; the quarterly check six weeks earlier recorded it "satisfactory". A fire in a bin store spread smoke into the landing and stairwell; two residents were treated for smoke inhalation and the block was evacuated. The fire and rescue service served an enforcement notice on the housing association, which claimed against the maintenance business for the remedial programme it then commissioned across all 62 blocks and for the disruption. The business had, on our advice the previous year, added £2m of PI with the fire safety exclusion deleted for regulation 10 checks.
What we did: Notified the PI insurer on the day of the fire. The insurer's panel obtained the tick-sheet records; the defence was weak — the record showed "satisfactory" against a door whose closer arm was missing, and no method statement existed to show what a "check" involved. We negotiated the claim on the basis that the housing association's decision to re-check all 62 blocks was a portfolio decision not caused by one missed door, and that the resident's interference was a contributory factor.
Outcome: Settled at £164,000 plus £38,000 defence costs under the PI policy. Renewal: PI from £4,200 to £7,900 (+88%) with a warranty that the tick-sheet is replaced by a scoped template recording each element, measurements and photographs; liability unchanged. The housing association renewed the contract on the strength of the new template.
Lessons: A quarterly check is a survey and its record is the evidence. With PI in place the business paid an excess; without it, £202,000 from a £1.6m-turnover business. The tick-sheet was the second claim waiting to happen.
Case study 3 — The replacement programme and the framework clause (composite, illustrative)
Situation: A fire door contractor with £2.8m turnover won a place on a council framework to replace 640 flat entrance doors across nine blocks over 11 metres. The framework's insurance schedule required £10m products liability "including efficacy of fire protection products", £2m PI "covering fire door survey and specification", and collateral warranties to the council's funder. The contractor's broker had confirmed compliance from a schedule that showed £10m and £2m without reading the exclusions. Fourteen months into the programme, a council-commissioned FDIS survey found 38 doors with threshold gaps outside the manufacturer's scope, caused by the contractor's decision to fit standard doorsets to uneven floors rather than specify drop seals. The council withheld £96,000, claimed the survey cost and the re-work, and served notice under the framework's insurance clause.
What we did: Engaged after the notice. The contractor's liability policy retained the efficacy exclusion and its PI carried a fire safety exclusion; the framework insurance clause had been breached from the first day, and the council's position was that the breach entitled it to terminate. We re-placed both policies inside three weeks with a specialist market — efficacy deleted for Q-Mark scope, PI with the fire safety exclusion deleted for survey and specification, retroactive date negotiated back to the programme start on a clean-history basis — and issued compliant certificates to the council. The specification claim was then notified to the new PI insurer as a circumstance known before inception and declined under the prior-circumstances exclusion.
Outcome: The 38-door re-work (£61,000) and the survey cost (£14,000) were borne by the contractor; the withheld £96,000 was released on completion of the re-work; the framework was not terminated. New premiums: liability £18,400 against £9,200 (+100%); PI £6,800 against £2,900. The programme completed.
Lessons: A schedule that shows the limit is not evidence the cover exists. Read the exclusions against the insurance clause before signing the framework — and fix the policy before the first door, not after the first survey.
How to manage a fire door claim — the eight-step process
- Notify liability and PI insurers the day you learn of a fire, an audit finding or a letter of claim. A fire at a building whose doors you installed, maintained or inspected, an enforcement notice on the responsible person, a fire risk assessor's adverse finding or a client's withholding is a circumstance under both policies. Notify both in writing through your broker; late notification is the most common reason claims are declined.
- Preserve the complete doorset and inspection record. Lock the doorset register, certificates and labels, installation checklists and photographs, inspection reports and measurements, handover packs and correspondence for the building. Do not amend, annotate or re-issue anything. The record is the defence or the admission.
- Do not attend site to inspect, adjust or replace doors without the insurers' agreement. An offer to fix the doors, an admission on site or an inspection without the adjuster can prejudice cover and the defence. Provide factual documents through the insurer's panel; leave liability to them.
- Establish which policy responds to which part of the claim. Third-party damage from a door failing to hold is liability with the efficacy deletion; the inspection report, the survey or the specification is PI; replacing or re-hanging your own doors is neither. Have the broker map the claim to the policies early so the insurers agree a split rather than dispute it.
- Identify every other party who may share responsibility. The responsible person's own maintenance duty, the resident who removed the closer, the doorset manufacturer whose evidence was unclear, the previous installer, the fire risk assessor and the principal contractor may each bear a share. Give the panel solicitor the names and the record.
- Notify legal expenses if the fire and rescue service or a regulator opens an enquiry. An interview under caution, a request for a witness statement in a prosecution of the responsible person or a Building Safety Regulator enquiry is a regulatory matter. Legal expenses cover, or the D&O policy's regulatory-investigation section, funds representation; instruct through the insurer.
- Notify every related circumstance to the expiring policies before renewal. Other buildings where the same doorset, operative or report template was used, other contracts for the same client and any further correspondence belong to the policy in force when they were first known. List and notify them so the renewal policies' prior-circumstances exclusions do not leave them uninsured.
- Present the process change at renewal, not the excuse. Underwriters price recurrence. Show the doorset-only policy, the scoped report template or the installation checklist that changed as a result, with the date, and present the claim as closed with a lesson applied. Diary the claim for five years of disclosure and challenge the loading as clean years accumulate.
Glossary of fire door and insurance terms
- BS 8214
- The British Standard code of practice for fire door assemblies — installation, gaps, fixings, seals, ironmongery and maintenance. The yardstick a claimant's expert measures an installation against.
- BS EN 1634-1 / BS 476-22
- The furnace test standards for fire resistance of door assemblies. Classification to BS EN 13501-2 (E, EI, EW with minutes) or the FD30/FD60 rating. The tested assembly defines what the installer must replicate.
- Certified doorset
- A complete door assembly — leaf, frame, seals, ironmongery and glazing — supplied as a tested unit under a third-party scheme such as Certifire, Q-Mark or the BWF Fire Door Alliance, with a label or plug on the leaf. The product a certified installer installs.
- Closer (controlled door closing device)
- The device to BS EN 1154 that returns the door to the closed and latched position from any angle. Its power size must match the leaf; a disconnected or under-powered closer is the most common maintenance failure.
- Efficacy exclusion
- A liability policy exclusion removing loss arising from a product or installation failing to perform its protective function. A fire door only causes loss by failing to hold; deletion for certified activities is the core of the placement.
- FDIS
- The Fire Door Inspection Scheme, offering a diploma in fire doors and certificated inspector status. The competence evidence underwriters expect for PI covering fire door inspection, and the methodology reports should follow.
- Flat entrance door (FED)
- The door between a flat and the common parts. Brought within the responsible person's fire risk assessment by the Fire Safety Act 2021 and subject to annual best-endeavours checks under regulation 10 in buildings over 11 metres.
- Gap
- The clearance between leaf and frame and at the threshold. Typically 2–4 mm at head and sides and up to 10 mm at the threshold (less with smoke control), as the test evidence specifies. 77% of doors failing FDIS inspection had excessive gaps.
- Intumescent and smoke seals
- Strips in the leaf or frame that expand in heat to close the gap (intumescent) and brush or fin seals that block cold smoke (smoke). Type, size and position must match the evidence; 37% of failed doors had seal faults.
- Q-Mark
- The BM TRADA (Warringtonfire) third-party certification schemes for fire doorsets, fire door installers and fire door maintainers. The installer and maintainer certificates most often asked for by name.
- Professional-advice exclusion
- A liability policy exclusion removing claims arising from advice, design, specification, survey or report given for a fee. Removes the inspection report from a joinery or maintenance liability policy; the answer is a PI policy alongside.
- Regulation 10
- Regulation 10 of the Fire Safety (England) Regulations 2022: in multi-occupied residential buildings over 11 metres, the responsible person must check common-parts fire doors at least quarterly and use best endeavours to check flat entrance doors at least annually, recording the checks.
- Regulation 38
- The Building Regulations 2010 requirement that fire safety information be given to the responsible person on completion. Doorset certificates, installation records and maintenance instructions form part of the handover.
- Responsible person
- Under article 3 of the Fire Safety Order, the employer, person in control or owner on whom every duty is placed — including maintaining fire doors under article 17 and the regulation 10 checks. The duty can be delegated to a contractor but not transferred.
- Scope of application
- The range of variations — sizes, ironmongery, glazing apertures, frame materials — a certification scheme permits from the tested assembly while the certification still applies. Outside it, the door has never been tested.
- Section 135 limitation
- The Building Safety Act 2022 provision extending Defective Premises Act 1972 claims to fifteen years prospectively and thirty years retrospectively from 28 June 2022. Flat entrance doors and common-parts doors in residential blocks are dwelling-related work.
- Supply-and-fit
- A contract under which the business supplies the doorset and installs it. Makes the business the producer of the product under the Consumer Protection Act 1987 as well as the installer, engaging products liability and, for volumes, product recall cover.
Frequently asked questions
Public and products liability with the efficacy exclusion deleted for certified fire door installation, employers' liability, contractors' professional indemnity for the on-site decisions every installer makes, contract works and tools, and legal expenses. A business that also carries out regulation 10 checks or inspections needs PI with the fire safety exclusion deleted for that work; a supply-and-fit business needs products liability as the producer of the doorset.
Almost never for the claim that matters. A joinery package policy rates fire doors as carpentry and carries the efficacy exclusion, removing loss from a fire door failing to perform its fire-resisting function — the only way a fire door causes loss. It also carries a professional-advice exclusion removing any inspection report. Fire door installation must be declared as an activity and the efficacy exclusion deleted for it, which requires third-party installer certification.
No. The test evidence covers a complete assembly — leaf, frame, seals, hinges, closer, latch, glazing and gaps — and the certification scheme's scope of application permits only limited variation. A certified leaf hung in an existing frame with different ironmongery, planed beyond the permitted margin or fitted with the wrong seals is an untested door, and the installer who assembled it is its producer in law. Complete certified doorsets are the insurable product.
Yes. A quarterly common-parts check or an annual flat entrance door check under the Fire Safety (England) Regulations 2022 is a survey, and the record you sign is a professional opinion the responsible person, the fire risk assessor and the Building Safety Regulator rely on. Liability policies exclude it under the professional-advice exclusion; only PI with the fire safety exclusion deleted for fire door inspection responds, and the limit should be sized to the portfolio, not the fee.
A clause on most contractors' liability wordings removing liability arising from a product, installation or system failing to perform the function for which it was intended, where that function is to protect against loss. For a fire door business it removes every claim arising from a door failing to hold fire or smoke. Specialist markets delete it for activities the business is third-party certified for — Q-Mark, FIRAS or IFC installer or maintainer scope.
Specialist markets treat third-party certification as the primary underwriting evidence and most decline uncertified fire door businesses or leave the efficacy exclusion in place. BM TRADA Q-Mark installer and maintainer schemes, FIRAS and IFC Certification installer scopes covering fire doors, and FDIS certification for inspectors are what underwriters ask for. The certificate scope defines the activities the exclusions are deleted for.
In contract six years from breach or twelve under a deed; in negligence six years from damage or three from knowledge with a fifteen-year longstop; and under the Defective Premises Act, since section 135 of the Building Safety Act 2022, fifteen years from completion for dwelling-related work and thirty years for work completed before 28 June 2022. Flat entrance doors and doors in the common parts of residential blocks are dwelling-related, and the damage is usually a fire years later.
Yes, on two bases. Liability cover is occurrence-based, so a fire after the business closes is covered only if a policy is in force on the date of the fire — products liability run-off provides that. Professional indemnity is claims-made, so a claim on an inspection report arriving after closure is covered only by PI run-off. Six years is the minimum and fifteen the prudent horizon for residential work. Budget it from the first year; it is far harder to buy after a gap or a decline.
The resident's interference is a contributory factor and the responsible person's maintenance duty under article 17 of the Fire Safety Order is its own, but a maintenance contractor who recorded the door as satisfactory at a check after the closer was removed has a professional negligence exposure for the missed defect. The defence is the record: a scoped report showing what was checked and when limits the claim; a tick-sheet marked satisfactory does not.
Yes. A business that supplies the doorset is a producer or supplier under the Consumer Protection Act 1987 and the General Product Safety Regulations, with strict liability for damage caused by a defect in the product, and the installer of it under the contract. Both liabilities need the efficacy exclusion deleted; a batch of non-performing doorsets across a housing portfolio is a recall event that only product recall cover, bought before the defect is known, will pay for.
Framework and principal contractor insurance clauses increasingly require products liability including efficacy of fire protection products and PI covering fire door survey and specification at stated limits. A policy whose schedule shows the limits but whose wording retains the efficacy or fire safety exclusion does not comply, and the contractor is in breach from the first day. Send the clause to your broker before signing and match the policy or amend the clause.
Look for a broker whose first questions are your certificate scope, whether you install complete doorsets or assemble on site, what your inspection report template records and what share of your work is flat entrance doors in buildings over 11 metres — not just your turnover — and who places through Lloyd's and specialist MGA markets with fire protection appetite rather than joinery package schemes. Miller & Partner places fire door businesses using The Insurability Framework, with the efficacy exclusion deleted for certified work, PI for inspection reports and run-off planned from the outset.
