The NHBC offers the Buildmark Certificate – a 10-year warranty for new homes and new conversions. In the first two years, your builder must rectify any defects resulting from the work they did, like leaky windows letting in rain, but not issues down to simple wear and tear.
The following three to 10 years are covered for structural problems resulting from the build – which includes the roof, floor, staircases, windows and doors.
NHBC Buildmark also covers you if you’ve exchanged contracts and the builder goes bankrupt before your property’s finished.
