What warranty protection do I get when buying a new-build home?
Most new-build homes in the UK come with a 10-year structural warranty (commonly an NHBC Buildmark policy, though other providers exist), covering the builder's defects liability for the first 2 years directly, then insurance-backed cover for major structural defects for the remaining years up to year 10 -- separate from your right to raise "snagging" issues (minor finishing defects) with the builder in the early months after completion.
Full answer
New-build warranties provide important protection that resale homes generally do not have, but understanding exactly what is covered, and when, avoids disappointment if something goes wrong. **The two-stage structure of a typical 10-year warranty** Most new-build warranties (NHBC Buildmark being the most common, alongside providers like Premier Guarantee, LABC Warranty, and others) split cover into two periods. In years 1-2 (the "defects insurance period"), the BUILDER is directly responsible for fixing defects that arise from their workmanship, materials, or design not meeting the warranty provider's technical standards -- you report issues to the builder first, with the warranty provider available to help resolve disputes if the builder does not respond adequately. From years 3-10 (the "structural insurance period"), cover shifts to protect against major structural defects only (such as issues affecting the foundations, load-bearing walls, or roof structure) via an insurance policy, rather than the builder being directly responsible -- this period does not cover general wear and tear, minor cosmetic issues, or things like decorating, unless they stem from an underlying structural defect. **Snagging -- separate from the warranty, and time-limited** "Snagging" refers to minor finishing defects (uneven paintwork, sticking doors, small cosmetic issues) that are common in new-build homes and typically should be reported directly to the builder within an initial period after moving in (often the first few weeks to a few months, though this varies by builder and is often set out in your specific completion documentation) -- these are generally the builder's responsibility to fix under their own customer service commitments and consumer protection code obligations, separate from the formal structural warranty. **What structural warranties do NOT cover** Structural warranties generally exclude: normal wear and tear, damage caused by the homeowner (e.g., from DIY alterations), issues with appliances (usually covered by separate manufacturer warranties), and cosmetic issues not linked to an underlying structural defect. They are specifically aimed at protecting against serious, expensive structural problems that a homeowner could not reasonably have anticipated or caused. **Why lenders require a warranty** Most mortgage lenders will not lend on a new-build property without an acceptable structural warranty in place (or an appropriate professional consultant's certificate as an alternative in limited cases), because the property has no track record and lenders want assurance against major latent defects emerging in the years after completion. **The New Homes Quality Code / Ombudsman** Since 2022, many major housebuilders have signed up to the New Homes Quality Code, backed by the New Homes Ombudsman Service, giving buyers of homes covered by participating builders an additional route to raise complaints about the quality of their new home and the builder's conduct, separate from both the structural warranty and any snagging process. **Worked example** A family moves into a new-build home and, within the first month, notices several doors do not close properly and some skirting boards are poorly finished -- this is snagging, reported directly to the builder's customer care team under their initial defects process, expected to be fixed at no cost within a reasonable time. Three years later, a significant crack appears in a load-bearing wall, indicating a possible foundation issue -- this falls within the structural insurance period of their 10-year warranty, and a claim is made to the warranty provider (not the original builder directly, since the builder's own 2-year defects liability period has ended), triggering an insurance-backed investigation and, if confirmed as a covered structural defect, repair. **Practical tip** Keep all your new-build documentation (warranty policy, builder's handover pack, snagging reports and responses) safely, since these will be needed both for warranty claims and if you sell the property before the 10-year warranty period ends, as the remaining warranty cover typically transfers to a new buyer.
