What is New-Build Warranty?
A structural warranty, typically lasting 10 years, that protects buyers of newly built UK homes against major defects in design, workmanship or materials.
Full Definition
A new-build warranty is insurance-backed cover that protects the buyer of a newly constructed home against serious structural and building defects. In the UK most new homes come with a 10-year warranty from a provider such as NHBC, LABC or Premier Guarantee. The cover is usually split: the first two years place responsibility on the builder to fix defects (snagging issues, faults in workmanship and materials), while years 3 to 10 provide insurance against major structural problems such as faults in the foundations, load-bearing walls or roof. A warranty is normally required before a mainstream lender will grant a mortgage on a new build. It transfers to subsequent owners if the property is sold within the warranty period. The warranty is not a maintenance contract and does not cover wear and tear, so buyers should still commission a snagging inspection and report defects in writing within the relevant period.
