How long is a builder liable for defects?

The defects period in your contract isn’t the end of the story. Depending on the claim, a builder can be liable for 6, 12, 15 or even 30 years. Here’s how the time limits fit together in England and Wales.

The time limits at a glance

ClaimTime limit (England and Wales)
Rectification (defects) periodAs set by the contract, often 12 months from practical completion
Breach of contract (signed simply)6 years from the breach
Breach of contract executed as a deed12 years from the breach
Negligence (latent damage)6 years from damage, or 3 years from when it could reasonably be discovered, subject to a 15-year longstop
Defective Premises Act 1972, section 1 (dwellings)15 years for claims arising from 28 June 2022; 30 years for claims that arose before then

For a contractor, the breach is often treated as occurring at practical completion. Scotland has different prescription rules.

Rectification period vs liability

The rectification period is a practical mechanism: the contractor returns to fix notified defects. It doesn’t usually end liability, so a client can still claim for defects found later within the limitation period. See what practical completion means.

The Defective Premises Act and building safety

Anyone taking on work for or in connection with providing a dwelling must do it in a workmanlike or professional manner so it is fit for habitation. The Building Safety Act 2022 extended the time limits, and the Supreme Court confirmed their reach in URS v BDW [2025]. Read our explainer and the key contract terms guide.

Frequently asked questions

My new home has defects. Who do I claim against?
Usually the builder or developer under your contract or warranty first, and possibly under the Defective Premises Act. New-build warranty schemes may also cover some defects. Take advice on time limits early.
