Contractor Insurance Checklist: 7 Policies for UK Contractors
The commercial property market is shifting. Rising rebuild costs, climate-related damage and legal changes mean landlords must reassess their cover.โฆ
Contractors insurance is a combination of covers built around running or overseeing a construction project, public liability for injury or damage, employersโ liability if you have staff, and cover for the added risk of managing subcontractors on site.
As the main or principal contractor, you can be liable for a subcontractorโs work even when you didnโt do it yourself. Your cover needs to reflect that, not just your own trade.
Contractors insurance can include:


Public Liability
Covers claims if your business injures a customer or damages their property.

Employersโ Liability
A legal requirement once you employ any staff, even casual help.

Professional Indemnity
Covers claims that your design or project management advice was negligent.

Business Contents
Protects equipment and materials kept at a yard or unit.

Tools & Equipment
Covers your tools against theft from the van or site.

| Your role on the project | Usually liable? | Why |
|---|---|---|
Main contractor managing subcontractors | Often, alongside the subcontractor | Youโre responsible for coordinating and overseeing the site |
Subcontractor working under your instruction | Yes, for their own actions | They carry their own liability, but you may too if you directed the work |
Subcontractor working directly for the client | Usually not, unless youโre also negligent | The contractual relationship sits with the client, not you |
You, doing the work yourself | Yes, directly | Standard public liability applies as with any trade |
Top Tip
Check what your contracts say about liability for subcontractors before you rely on their insurance alone, you may still be exposed even when someone else did the work.
Thereโs no fixed price. It depends on the size of projects you run, how many subcontractors you use, whether you have staff and your claims history.
Size of projects
Larger, more complex projects carry more risk than small jobs.
Level of cover
Higher limits and non-negligent liability cover increase your premium.
Number of subcontractors
More subcontractors on a project increase your oversight risk.
Type of contracts
JCT and other formal contracts can affect the cover you need.
Number of direct staff
More employees increase your employersโ liability exposure.
Claims history
A clean claims record helps keep premiums down at renewal.
