Do I need contract works insurance for a self-build?
Yes — in almost all self-build cases you need dedicated contract works insurance, because standard home insurance typically excludes an uninhabited property mid-construction, and most self-build mortgage lenders make it a condition of releasing each stage of funds.
- Standard home insurance almost always excludes a property that's uninhabited or under construction.
- Self-build mortgage lenders commonly require proof of contract works cover before releasing stage payments.
- Cover should include materials on site, the part-built structure, and public liability for visitors and neighbours.
- Self-build-specific policies often bundle in structural warranty support that standard CAR policies don't.
- Cover typically needs to convert to standard buildings insurance once the property becomes habitable.

What good self-build cover includes
Storm damage during a self-build stall
Scenario: A self-builder's timber-frame structure was left exposed over a wet winter after a delay in the roofing schedule, and a storm caused water ingress that warped several structural timbers.
Resolution & Judicial Outcome: Because the self-build contract works policy was still active and had not lapsed despite the delay, the claim for replacing the damaged timbers was accepted, though the homeowner had to demonstrate reasonable steps had been taken to protect the site (temporary sheeting) during the gap.
What You Should Do: Step-by-Step Action Plan
Critical Mistakes to Avoid
- Relying on an existing home policy that wasn't designed for construction or an unoccupied property.
- Letting cover lapse during a pause in the build without adding extra site security.
- Under-declaring the rebuild value to save on premium.
- Forgetting to arrange standard buildings insurance once the self-build policy's cover period ends.
