The Building Regulations are approved by Parliament and manage the minimum standards of design and building work required for the construction of domestic, commercial and industrial buildings. They also specify the definitions of what is regarded as "building work" and the procedures for ensuring that it meets the standards laid down.
The Building Regulations also contain a list of requirement which are established to ensure the health and safety of people in and around buildings; to provide for energy conservation and to supply access and facilities for disabled people. There are 13 parts (A-H and J-N) to these requirements and cover subjects including fire safety, structure, drainage, ventilation, energy conservation and access and facilities for disabled people. The requirements are conveyed in broad, functional terms in order to give designers and builders the maximum amount of flexibility in preparing their plans.
