Established in 1936, we are the UK's leading warranty and insurance provider for new homes.
We currently provide warranty and insurance for over 1.5 million homes. Over the course of our history, we have provided warranty for around 30% of the total existing housing stock in the UK.
Our main warranty and insurance product, Buildmark, covers homes from before they are built, providing protection to the homebuyer from the exchange of contracts through to the end of the 10th year following legal completion by the first homeowner.
With no shareholders, we are able to dedicate resources and technical expertise to support the industry in raising the standards of new homes. As an independent authority on the housing industry, active in research and development (including through our NHBC Foundation), we work with government and stakeholders to help shape housing policy and practice.
To sell homes with NHBC Buildmark cover, our registered builders must comply with the NHBC requirements which form part of the NHBC Standards. As well as providing our technical build requirements, the NHBC Standards set the performance standards and provide guidance for the design and construction of new homes acceptable to NHBC.
We regularly review and update the NHBC Standards. A full electronic version, with additional explanatory notes, videos and 3D models is always available on our website.
Our in-house engineers, surveyors and building inspectors provide our registered builders with technical support to help at every stage of new home construction, providing guidance on Standards, Building Regulations, research and other technical issues.
Our building inspectors typically carry out over 900,000 on-site inspections at key build stages each year, supporting the industry in the delivery of high quality, new homes. We use data from our inspection records and homeowner satisfaction surveys to create our Construction Quality Index which we use to measure fluctuations in construction standards and the drivers behind them.
