INSURANCE FOR MAIN & PRINCIPAL CONTRACTORS
Cover Built Around How General Contractors Actually Work
As a general contractor, you may act as principal contractor, manage multiple trades, sub-contract significant parts of the work and carry responsibility for health & safety, project delivery and quality. Your insurance needs to reflect this - protecting your liability, your works, your people, your plant and your reputation.

- Bona-Fide Subcontractors – checking and managing their cover.
- Labour-only Operatives – included under EL where applicable.
- Products Liability – completed works causing injury or damage.
Works, Plant & Property

FREQUENTLY ASKED QUESTIONS
+-
+
-
Do I need different insurance for residential and commercial projects?
Not necessarily. Many general contractor policies can cover both residential
and commercial work, but insurers will want to understand the split, project
values and any higher-risk activities. We’ll structure cover to match your
actual workload.
+
-
Are my subcontractors covered under my policy?
Labour-only subcontractors are usually treated like employees and can be
included under your liability cover, whereas bona-fide subcontractors
typically need their own insurance. We can help you put the right arrangements
and checks in place.
+
-
What limit of public liability should a general contractor carry?
This depends on the size and nature of your projects and the contracts you
work under. Many contractors buy £2m–£5m as standard, with higher limits
required for larger or higher-risk sites. We can advise on appropriate limits
based on your risk profile.
+
-
Do I need contractors all risks if the client already insures the building?
Even where a client insures the existing structure, you may still need
contract works cover for the works you are carrying out and for your plant,
materials and temporary works. Contract conditions and JCT wording often
dictate who insures what.
+
-
Can Insure24 help if my work includes higher-risk activities?
Yes. If you undertake higher-risk work such as roofing, basement digging,
structural alterations or work with heat, we can present your risk properly
to insurers and look for suitable markets and wordings.
