Accepted Systems

An NHBC Accepts logo shows that an innovative system has been rigorously assessed and that we consider it can meet our robust NHBC Standards. It also demonstrates that, subject to appropriate design and installation, the system can be used in homes covered by all our warranty products.
The Modern Methods of Construction (MMC) category is taken from the categorisation as per Government definition framework and as proposed by system owner. This definition framework has been developed by a specialist sub-group of the MHCLG MMC cross industry working group.
