In England and Wales, building design and construction is governed by the Building Regulations. These regulations comprise a series of requirements for specific purposes: health and safety, energy conservation, prevention of contamination of water and the welfare and convenience of persons in or about buildings. Part M of the Regulations sets minimum legal standards for access and use of buildings by all building users, including disabled people.

Since a requirement for access was first introduced in 1985, there have been a number of changes to and extensions in the scope of access regulations. The building regulations avoid specific reference to, and a definition of, disabled people. This inclusive approach means that buildings and their facilities should be accessible and usable by all people who use buildings - including parents with children, older people and disabled people. Previously, Part M covered new buildings and extensions to existing buildings. The 2004 revision brings Part M into line with other parts of the Building Regulations by extending its scope to include alterations to existing buildings and certain changes of use.
Building Regulations are supported by 'Approved Documents' which give practical guidance with respect to the regulations. While their use is not mandatory - and the requirements of regulations can be met in other ways – Approved Documents are used as a benchmark by the local authority. The new Approved Document M (AD M), published in November 2003, offers technical guidance on providing access to and within buildings.
