What is Buildmark?

Buildmark is our warranty and insurance product for newly built or newly converted homes. It currently protects around 1.5 million homes in the UK.

Buildmark provides pre-completion deposit protection; a two year builder warranty period backed by the NHBC resolution service and guarantee; and then an eight year insurance policy for physical damage to the home caused by a failure to build to the NHBC Technical Requirements.

  • Cover against contaminated land

The above applies to policies for plots registered with us from 1 October 2019. Please see the full Buildmark policy document below for all the conditions and exclusions that apply. Homes registered prior to 1 October 2019 may benefit from insurance protection for certain breaches of Building Regulations if NHBC Building Control Services Limited is appointed for and carries out building control for the property. If we have provided this cover, it will be clearly shown on the Buildmark insurance certificate, and a description of the cover included in the policy booklet. Please refer to your own policy documents for all the terms and conditions that apply to your home.

* The minimum claim value explained: We don’t require policyholders to pay the first part of any claim. Instead, we operate a minimum claim value (MCV) which means that if the cost of a valid claim exceeds the MCV we will do the work or pay the cost in full and the policyholder will not have to make any contribution. The MCV for policies starting on 1 April 2019 is £1,750 (increasing by £50 on 1 April in each subsequent year).
