New-Build Warranties in the UK: What a 10-Year Structural Warranty Does and Does Not Cover
Most new-build homes in England and Wales come with a structural warranty, often described as a 10-year warranty. It is useful protection, but it is narrower than many buyers assume.
This guide explains how these warranties are usually structured, what they typically exclude, and what to ask before you exchange contracts.
The short answer
A new-build warranty usually has two stages. In the first period, typically the first two years, the builder is responsible for putting right defects and the warranty provider backs that obligation if the builder fails. In the later years, cover usually narrows to major structural damage. The exact terms depend on the provider and policy, so read the policy documents.
Who provides them
Warranties are issued by providers such as NHBC, Premier Guarantee and LABC Warranty, among others. Lenders generally expect a recognised warranty on a new-build and may not lend without one. Ask your solicitor to confirm which provider is used and that the policy or cover note is in place before exchange.
What these warranties usually do not cover
- Normal wear and tear and cosmetic issues once the early defects period has passed.
- Fixtures and fittings you add yourself.
- Problems caused by lack of maintenance.
- Common parts in a flat, which are often covered by the building's own arrangements. Ask how this works.
Warranty versus snagging
Snagging is the list of finishing defects you find at completion. Report them to the builder promptly and in writing. Our new-build snagging checklist for overseas buyers shows what to check, and the reservation agreement guide covers the earlier stage.
Questions for your solicitor
- Which warranty provider is used, and how long does each stage last?
- How do I report a defect, and who do I contact at each stage?
- Is there a cap on claims, and what excess applies?
- For a flat, how are the communal areas covered?
- Does the warranty transfer if I sell?
If you are buying from abroad
Keep a record of the warranty documents, the builder's contact route and key dates, because a defect claim may arise after you have returned overseas. Appoint a local contact, such as a managing agent, if you will let the home out.
