Cover from exchange of contracts
Buildmark provides your client with pre-completion cover if you're unable to complete the build.
Custom-build, build-to-contract and self-build homes
Whether it's a modest bungalow or on a grander scale, Buildmark is the warranty and insurance product for custom-built homes
Why choose NHBC for custom-built homes?
If you’ve been appointed to build a home on behalf of an individual client who intends to live there, then Buildmark is the right warranty and insurance product to choose because you and your client will benefit from:
10 years cover after completion
Buildmark will provide warranty and insurance cover for the new home for 10 years post-completion. Unlike with an Architect's Certificate, as long as the terms of Buildmark cover are met, there is no need for the home buyer to prove negligence in the event of a claim.
Expert technical support
Your allocated building inspector will visit your site at key build stages to support you in meeting NHBC standards. The relationships our field-based inspectors have with our builders, backed by our extensive in-house technical expertise and full customer service support, are highly valued.
Association with market-leading brand
We are the leading warranty and insurance provider for new homes in the UK. Our Buildmark cover product covers around 70-80% of new homes built in the UK.
A one-stop shop for warranty, Building Control and consultancy services
For consistency, quality and efficiency many of our builders choose to work with us for Building Control as well as services such as health and safety consultancy, energy ratings and land quality endorsement. We are a unique source of information, data and support.
Buildmark for custom-built homes
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 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.

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.

You need to be registered with NHBC to offer Buildmark warranty and cover for your new homes. If you’re not yet registered with us, please visit the NHBC registration section first. If you’re already registered with us, you can send us the details of your new site straight away.
Self-build homes
If you’re building a home to live in yourself (we call this self-build) then we don’t currently offer our own warranty and insurance product. However, we have an agreement with Self-Build Zone, one of the market-leading suppliers in the self-build sector, who you can approach to discuss your self-build warranty, site insurance and other requirements.
