How long is a builder liable for their work?

Reviewed by Sean McNamara, 2026-10-07

Builders remain answerable for their work long after the van leaves - but the answerable-for window depends on the legal basis: contract limitation, statutory rights, insurance-backed guarantees, and the practical difficulty of proving later defects.

The clock-start nuance that decides late cases

A defect visible on completion starts the clock at completion; a latent defect (hidden - e.g. wrong foundations surfacing at year 4) may start the clock at DISCOVERY for some claims. Document the discovery date contemporaneously: an email to the builder saying 'following the leak that revealed X on [date]' is worth more than a folder of later photos.,

Practical protection for FUTURE work

Retention: hold 5-10% until a defined defects period ends. Written guarantee with insurance backing: ask whether the guarantee survives insolvency. Snag-sheet procedure in the contract: how defects get reported and how fast they're fixed. The one-line summary: liability law gives you years, but paperwork gives you leverage.

Questions this page answers

How long is a builder liable for their work?
Contract claims: up to 6 years from breach (England and Wales) under the Limitation Act. Statutory rights under the Supply of Goods and Services Act / Consumer Rights Act: reasonable care and skill is required at performance; the LIMITATION window still governs when you can sue. Latent defects: the clock generally runs from when the defect was (or should have been) discoverable in negligence claims - a specialist area worth a solicitor's glance.
How long is a builder liable for his work in the UK?
Same 6-year contract baseline. Caveats: the builder's death/dissolution ends practical recourse; 'guarantees' may promise longer or shorter periods with their own terms; and new-build homes fall under separate regimes (warranty providers with their own timelines).
How long does a builder have to warranty their work?
Whatever their written guarantee says - there's no statutory minimum warranty period for general building work. Read the guarantee's scope (materials vs labour, notification windows in writing, exclusions). Insurance-backed guarantees (IBGs) survive the builder's disappearance; plain company guarantees may not.
How long is a tradesman liable for his work?
Same framework: 6 years contractual. Practically: report defects IN WRITING as soon as found - delay both weakens evidence and can support an argument you accepted the work.
How long should a builder guarantee work in the UK?
Market norms: 12 months on general labour is common; structural work, damp-proofing and roofing often carry longer guarantees (10+ years from specialist bodies with insurance backing). 'Reasonable' for the trade matters under the CRA: what a competent builder guarantees is evidence of the standard you can claim against.

Before escalating: preserve the contract, photographs, payment record and independent assessment. A structured evidence bundle is often more useful than a longer email.
