NHBC Standards

Your essential guide to house building from foundations to roofs and finishing

What are NHBC Standards?

The NHBC Standards define the technical requirements and performance standards for the design and construction of new homes registered with us and provide guidance on how these can be achieved.

Our dedicated Standards team is continually working to develop technical content and updates to the Standards, working with stakeholders from across the industry.  This means that the Standards are always relevant, providing additional support and guidance to help builders and developers deliver the highest possible new home standards for the benefit of people living in them.
