Demolition Contractors Insurance
Demolition is one of the few construction trades that most standard markets will not write at all. The reason is not that demolition contractors are careless; it is that the work deliberately induces structural failure next to things that must not fail, and the difference between a controlled collapse and an uncontrolled one is measured in the accuracy of a survey and the judgement of the person calling it.
That makes this a specialist placement rather than a package purchase. The underwriters who write demolition want to know about your structural survey process, your temporary works and propping, your exclusion zones and your competence, and they will price on those far more than on turnover. A contractor who can evidence all four gets terms; one who cannot usually gets declined regardless of price.
We arrange cover for demolition and soft strip contractors, including work adjacent to occupied buildings and within town centres, and the practical work is presenting the risk properly to markets that understand the difference between a full structural demolition and a strip out.
What actually goes wrong
The exposures that produce claims in this trade, rather than a generic list.
Adjacent structures and party walls
Most demolition claims are not about the building coming down but about what happens to the one next to it. Removing a building removes lateral restraint from a shared or abutting wall, and the neighbouring property can crack, move or admit water. Party wall awards, condition surveys and photographic records taken before work starts are what make these claims defensible.
Uncontrolled or premature collapse
Structures fail differently from how the drawings suggest, particularly where previous alterations were never recorded. A progressive collapse that goes beyond the intended sequence puts operatives, plant and third parties at risk simultaneously, and it is the loss type that defines how this class is underwritten.
Asbestos and hazardous materials
A refurbishment and demolition survey is expected before intrusive work on any building that may contain asbestos, which means effectively any building predating 2000. Beyond asbestos there are contaminated tanks, lead, PCBs in older electrical equipment and residues in industrial buildings. Almost all of it is excluded from standard liability wordings.
Dust, noise and vibration
Nuisance claims from neighbouring occupiers are common and are treated differently from damage claims. Vibration from breaking and high reach work can crack finishes in adjacent buildings without causing structural damage, which produces a stream of modest claims that are individually small and collectively expensive.
Services still live
Buildings coming down are supposed to be disconnected, and are not always. A gas supply that was capped upstream but not purged, or an electrical supply left energised by a utility, turns a routine demolition into a serious incident. Written confirmation of disconnection from each utility is the control insurers look for.
The cover we arrange
Policies are put together around how you work. Employers liability is included as standard wherever you employ anyone.
Public liability at demolition limits
The core cover, at limits that reflect the adjacent property exposure rather than the contract value. £10m is the practical working limit for most demolition, and larger urban contracts frequently require more.
- Third party injury and property damage
- Damage to adjacent and neighbouring structures
- Limits typically £10m and above
- Nuisance from dust, noise and vibration where available
Employers liability
Legally required and included as standard at £10m. On demolition the underwriting focus is competence and supervision, since the hazard controls are almost entirely procedural rather than physical.
- Legally required, £10m as standard
- Plant operators and topmen
- Training and certification records
- Occupational illness including dust exposure
Contract works
On demolition the works are usually the removal itself rather than something being built, so cover focuses on temporary works, propping, hoarding, protection and any elements being retained for reuse or facade retention.
- Temporary works and propping
- Facade retention structures
- Hoarding, scaffolding and protection
- Salvaged materials awaiting removal
Contractors plant
High reach excavators, crushers, breakers and grabs represent substantial value and are attractive to thieves on cleared sites. Owned plant is usually scheduled individually at this value, and hired in plant needs continuing hire charges included.
- High reach and specialist plant, scheduled
- Attachments, breakers and shears
- Hired in plant and continuing hire charges
- Tracking and immobilisation
Professional indemnity
Needed where you plan the demolition sequence, design temporary works or advise on structural stability, which most demolition contractors do as a matter of course. It is the cover that responds when the method was wrong rather than when somebody was careless in executing it.
- Demolition method and sequence planning
- Temporary works and propping design
- Structural stability advice
- Claims made basis, maintained after completion
What an underwriter will ask
Having these to hand shortens the process considerably, and usually improves the terms.
- Turnover split between full demolition, partial demolition and soft strip
- The tallest and largest structure you have taken down, and what you would take on
- Whether you work adjacent to occupied buildings, highways or railways
- Your structural survey process and who carries it out
- Temporary works design: in house, or by an external engineer
- Asbestos procedure, including who holds the licence for licensed work
- Whether explosives are ever used, by you or by a subcontractor
- Plant schedule with values, and high reach machine details
- Accreditations and trade body membership
- Five years of claims, including neighbour and nuisance complaints that did not become claims
What moves the premium
Where the price actually comes from, and which parts of it you can change.
The tallest structure you take on
Height and structural complexity drive this class more than turnover. A contractor doing high volume soft strip prices very differently from one doing occasional multi storey structural demolition at the same revenue.
Proximity to other buildings
Isolated industrial demolition on a cleared site is a different risk from a terrace end in a town centre. Being able to describe the split honestly gets a better outcome than a single average.
Survey and temporary works process
Whether structural surveys and temporary works designs are produced by a qualified engineer, and retained, is among the strongest indicators underwriters use in this class.
Accreditation
Recognised trade body membership and audited accreditation carry real weight, because they substitute for the underwriter having to assess competence from scratch.
Claims and complaint history
Neighbour complaints matter even when they never became claims, because they indicate how the work affects its surroundings. A clean record with documented condition surveys is worth more than a low turnover.
Conditions and exclusions that catch this trade out
Terms vary between insurers, so treat these as the questions to ask rather than a description of any one policy.
Explosives
Use of explosives is excluded on virtually every wording and requires a specialist placement. If explosive demolition is even occasionally subcontracted, it needs declaring, because engaging a specialist does not automatically remove you from the liability chain.
Asbestos
Excluded on most policies for both liability and removal cost. Demolition contractors encounter it more than any other trade, so the control has to be procedural: survey first, stop on discovery, and use appropriately licensed contractors for licensed work.
Height and structure size limits
Many wordings restrict demolition above a stated height or number of storeys, and above that threshold the risk is referred rather than automatically covered. Working beyond an undeclared limit can put the entire operation outside cover.
Vibration and weakening of support
Damage to adjacent property caused by vibration, or by removal of support, is sometimes excluded or restricted unless specifically extended. Since it is the most likely claim in this trade, checking whether the extension is in place matters more than checking almost anything else.
Contaminated land and gradual pollution
Cleaning up contamination discovered on site, and gradual pollution over time, are generally excluded. Only sudden and accidental pollution incidents affecting third party land are typically covered.
Common questions
Why is demolition insurance so hard to get?
Because the work deliberately causes structural failure, usually close to buildings that must not fail, and the controls are procedural rather than physical. Most standard construction schemes exclude demolition outright, so it goes to a smaller group of specialist underwriters. Those markets are open to well run contractors, but they underwrite on survey process, temporary works design, competence and accreditation rather than on price. Presenting that information properly is what gets terms.
What public liability limit do demolition contractors need?
£10m is the practical working minimum, and many urban and commercial contracts require more. The reason the limit is higher than for general building is that the exposure is not driven by the value of your contract but by the value of what is next to it. Demolishing a modest building attached to a larger occupied one carries the larger building's exposure, whatever your fee.
Am I covered for damage to the building next door?
Damage to a genuinely third party neighbouring building is a public liability matter and would normally be covered, but two qualifications matter. Some wordings restrict damage caused by vibration or by removal of support, which is exactly how demolition damages neighbours, so that extension needs checking. And your ability to defend the proportion attributable to you depends almost entirely on having a pre works condition survey with photographs, because otherwise every existing crack becomes yours.
Does demolition insurance cover asbestos removal?
Generally no. Asbestos is excluded on most policies, both for liability arising from exposure and for the cost of removal and remediation. Since any building predating 2000 may contain it, the practical protection is procedural: obtain a refurbishment and demolition survey before intrusive work, stop immediately on unexpected discovery, and use a licensed contractor where the material requires one. Some specialist markets will consider asbestos cover separately.
Do demolition contractors need professional indemnity?
Usually yes, and more obviously than most trades. Planning a demolition sequence, deciding what needs propping and advising on structural stability are all design and advisory activities. Public liability responds when somebody is injured or property is damaged; it does not respond to the cost of a method being wrong. Where you produce temporary works designs in house rather than commissioning an engineer, professional indemnity is doing real work.
Is soft strip insured differently from structural demolition?
Yes, and it is worth separating them in your figures. Soft strip removes non structural elements and fittings without affecting stability, so it rates much closer to refurbishment than to demolition. Structural demolition attracts the specialist rating. A contractor whose turnover is mostly soft strip, presented as undifferentiated demolition, is paying for exposure it does not have.
