A building contractor’s public liability enquiry should describe the jobs actually undertaken, not just use the word builder. Work at height, subcontractors and responsibility for existing property can change what an insurer is being asked to accept.
The decision that deserves the closest review
Separate injury or damage to third parties from damage to the work being built. Provide examples of renovation, demolition and specialist tasks. Ask about height, depth, heat work and subcontractor conditions where these are relevant to your operations.
A hypothetical example
A contractor adds roof repairs to a business previously doing internal refurbishment. A comparable enquiry discloses the new height exposure and checks it against the schedule before accepting a job.
Third-party injury and damage
Public liability discussions focus on injury or property damage affecting third parties. Professional mistakes, employees, damage to the work itself and the business’s own assets can require different sections. Start by separating these exposures in the enquiry.
Premiums, excesses and usable cover
Request quotations using the same business description, required limits and relevant dates. Put the annual premium, any instalment charges, excesses and important sublimits in one comparison. A cheaper premium can represent a different transfer of risk rather than the same cover at a better price.
| Comparison item | Question to resolve |
|---|---|
| Height, depth and specialist work | Are all current trade activities accepted? |
| Subcontractor arrangements | Which subcontractor evidence must be kept? |
| Third-party and existing-property exposure | Is damage to the work itself a separate cover issue? |
Request the proposed wording and schedule, not just a price or certificate. Mark any difference that affects a real activity before deciding whether the premium saving is worthwhile.
Prepare an accurate insurance enquiry
Give each adviser a consistent description of the activities being insured. Include important contracts, changes since the previous enquiry and matters the insurer asks you to disclose. Do not guess answers merely to obtain a faster or cheaper quote; ask for clarification when the proposal wording is unclear.
Use a site activity schedule in every quote request
List the building tasks performed directly, the work subcontracted and activities that occur near occupied property. Note excavation, heat-producing work, height and public access where relevant. Ask the adviser which details are needed rather than leaving an important activity inside the broad word builder.
Compare policy conditions against the way sites are actually run. Where a condition requires a particular precaution, establish who performs and records it. Keep public liability, employee-related cover and insurance for works or existing property as distinct comparison questions, even when one package offers several sections.
Include overseas work or sales in the UK business’s enquiry and confirm the accepted territories and jurisdictions.
A mistake to avoid
Expecting liability insurance to pay automatically for replacing the contractor’s own defective work.
Check what happens after the policy starts
Ask who to contact when activities change or a potential claim arises. Understand the notification and consent process before arranging repairs, appointing specialists or settling a complaint. At renewal, compare the new documents with the accepted business description; continuity of a familiar brand does not prove continuity of every term.
Questions before choosing
Does a client’s requested limit settle the enquiry?
It establishes a contractual request, but scope, exclusions and working-method conditions still need review.
Does public liability insure the value of the renovation itself?
Ask separately about the works and existing property. Protection against third-party allegations should not be treated as automatic cover for every part of the contractor’s project.
