Demolition Insurance UK — For the Risks Standard Policies Exclude by Name

Very often it does not, and for a demolition contractor that is the most consequential line on the schedule. After the market's experience with asbestos claims, most modern liability wordings carry a blanket asbestos exclusion covering injury, damage and clean-up arising from asbestos in any form. It can apply whether or not you hold a licence, and whether or not you knew the material was there — which matters because demolition and soft strip routinely open up voids that surveys missed. Where cover is available it may be written back for defined licensed activity, sometimes on a claims-made rather than occurrence basis, which changes your run-off position entirely. Read your schedule for the word "asbestos" before your next job. If it appears only in an exclusion, you need a conversation rather than a renewal.

Usually not, and this catches contractors out constantly. Contract works and Contractors All Risks sections are designed for something being built; they cover the works in progress. In demolition there are no works being constructed, and the structure is normally the client's property, which brings it within the standard "existing structures" exclusion. The practical consequence is that damage beyond your agreed scope — the wrong bay taken down, over-demolition, a collapse into a retained element, damage to a facade you were meant to preserve — can fall outside every section of your policy. An existing structures extension addresses it, and it becomes essential the moment any part of the building or an adjoining one is to remain standing. Facade retention schemes should never proceed without it confirmed in writing.

£5m is the practical floor and £10m is standard for local authority, framework and city-centre work. Some principal contractors on major schemes specify more. The limit that matters is whatever your contract requires, and being underinsured against a contractual requirement can put you in breach before you mobilise. Because demolition carries genuine catastrophe potential — an uncontrolled collapse in a built-up area can affect multiple third parties simultaneously — higher limits are worth more here than in most trades. The rate curve also flattens above £5m, so moving to £10m often costs a fraction of the base premium. Where limits genuinely bite is on the sublimits sitting inside the headline figure for support, vibration and existing structures. That is where the conversation should focus.

Only if the extension has been bought. Standard Public Liability contains a named exclusion for damage caused by vibration, or by the removal or weakening of support — which is exactly how demolition damages an adjoining property. Taking down a structure changes the loading, the weather protection and sometimes the stability of everything attached to it, and terraced and party wall situations make that unavoidable. The exclusion is bought back as a support, collapse and vibration extension, and not every market grants it for demolition. Alongside the insurance position sits the Party Wall etc. Act 1996, with notice obligations and a statutory compensation route independent of negligence. A dated pre-works condition survey is the cheapest protection available and repeatedly decides these disputes.

Because it is shaping up as the next long-latency disease wave, and the policy that pays is the one you buy today. The HSE describes respirable crystalline silica as construction's biggest occupational cancer risk after asbestos, and in May 2026 it launched a nationwide enforcement programme of more than 1,000 inspections, with prohibition notices already served. Demolition generates RCS at volume — concrete, brick, stone and mortar all release it when broken, cut or crushed. Employers' Liability is written on an occurrence basis, which means a silicosis or lung cancer claim brought decades from now attaches to the policy in force when the exposure happened. That makes dust control, RPE fit testing and health surveillance records a commercial matter, not just a compliance one. Underwriters have started asking.

For most demolition work in England and Wales, yes. Section 80 of the Building Act 1984 requires notice to the local authority before demolishing a building or part of one, with limited exemptions for small structures and certain agricultural buildings. The authority can then impose conditions under section 81 covering matters such as shoring adjacent buildings, making good, sealing services and site security. Those conditions are enforceable, and failing to comply is an offence. From an insurance perspective the notice and the conditions form part of the evidential record if anything goes wrong, and an insurer looking at a collapse claim will ask to see them. This sits alongside, not instead of, planning permission and Party Wall obligations.

Yes, and declines in this trade are common enough that they tell you very little about the business. Demolition is refused by mainstream schemes as a matter of routine — often by an automated system that reads the SIC code and stops, before anyone examines your method statements, survey discipline or loss record. That is a distribution problem rather than an insurability one. The same applies to a collapse claim, a disease claim, a CCJ or cover cancelled mid-term: a specialist underwriter wants to know what happened, what changed afterwards and how the change is evidenced. We place businesses refused cover, adverse credit cases and post-insolvency risks routinely. Disclose the history up front.

Yes, and it needs two components. First, physical damage cover for the machine, because hire conditions typically make you responsible for loss or damage however caused — and a high-reach excavator can be worth more than the rest of your fleet combined. Second, continuing hire charges: if a machine is destroyed or stolen, the hire company keeps invoicing the rental until it is replaced, and lead times on specialist demolition plant run to months rather than weeks. A hired-in plant section without continuing hire charges leaves a large and entirely predictable gap. Check the sum insured reflects the highest-value machine you might have on hire at any moment, not the one you usually take, and confirm whether attachments such as shears, munchers and pulverisers are included or scheduled separately.

If you design any part of the sequence, yes — and most structural demolition contractors do without labelling it design. Deciding the order of removal, specifying propping or temporary works, determining exclusion zones, or proposing an alternative method to the one tendered all bring you within professional negligence territory. On facade retention and partial demolition the design element is unavoidable. Professional Indemnity is claims-made, meaning the policy in force when the claim is made responds rather than the one in force when the work was done, so the retroactive date and run-off cover matter as much as the limit — particularly if you change insurer or wind the company up. On NEC and framework contracts PI is frequently required whether or not you consider yourself a designer.

Only if it has been declared and insured as stock or materials on site, and the sums insured reflect current metal prices rather than what they were when the policy was written. Recovered steel, copper, lead and cable are high value, highly portable and a persistent theft target, and demolition sites are by definition open, temporary and hard to secure. Most policies apply conditions around fencing, lighting, storage and whether material is left on site overnight, and those conditions are enforced at claim stage. Two practical points: get the salvage value question settled contractually with your client before you start, because ownership of recovered material is often ambiguous, and review sums insured mid-term if scrap prices move sharply. Underinsurance here is common and entirely avoidable.

The levers are evidential and structural. Get your asbestos discipline documented — surveys obtained and read, stop-work protocol, awareness training per operative, records retained. Invest in dust control and health surveillance, and be able to show it, because that is where underwriter attention is moving. Keep method statements aligned to BS 6187 with temporary works properly designed and checked. Segment your work honestly so occasional high-reach or licensed activity is not rating your whole book. Cap contractual liability where clients allow it and have supply chain agreements read before signature. Secure sites properly and get plant CESAR-marked and tracked. Present the risk as a document rather than a form, and start the renewal six weeks out — specialist markets need time to underwrite this properly.

Ask three questions. First, what the policy says about asbestos — excluded, written back, occurrence or claims-made. A broker who cannot answer that instantly is not a demolition broker. Second, how existing structures are treated, because if they cannot explain why the building you are demolishing might not be insured, they have not read a demolition schedule properly. Third, whether they can place a contractor with a collapse or disease claim on record, which tells you whether they hold specialist and Lloyd's access or only a scheme.
