NHBC guidelines

NHBC, (the National House-Building Council), is the standard setting body for new and newly converted homes in the UK. Their role is to work with the house-building and wider construction industry to provide risk management services that raise the standards of new homes, and to provide consumer protection to new home buyers.

There are approximately 20,500 house builders and developers on NHBC's register (known as registered builders or registered developers), who agree to comply with the NHBC Rules and Standards when building new homes.

More than 80% of new homes built in the UK each year are registered with NHBC and benefit from the NHBC 10-year warranty and insurance policy called 'Buildmark'. Around 1.7 million homeowners are currently covered by Buildmark policies, and over the past 40 years, NHBC has protected more than 30% of existing homes in the UK.

Technical Standards

NHBC Standards are the 'bible' for the registered house builder and provide the benchmark for acceptable levels of design, material specification and workmanship for newly-built homes registered with NHBC. They are an essential part of NHBC's risk management.

For example, having correct Standards for foundations should keep foundation-related problems to a minimum, benefiting both homeowners and house builders.

NHBC Standards have a section dealing with each part of the building process, from foundations all the way through to painting and decorating and including specific requirements for the specifications of the space heating system.
