This 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 plots registered from 1 April 2019 is £1,750 (increasing by £50 on 1 April in each subsequent year).

To see all the terms and conditions and policy limits that apply, please see the current Buildmark policy document that applies to newly built, converted or renovated homes registered with us from 1 April 2021.
