Guidance on Building Regulations

What are the building regulations?

The Building Regulations are legal requirements designed to ensure the health and safety of building users. They also take into account energy conservation, and access and use of buildings by people, including disabled people. The regulations themselves are in the form of a 40 page document known as a statutory instrument. This simply states the regulations but doesn't itself elaborate or give guidance on how to comply or meet the regulations.

To give additional guidance, there are a series of approved documents published. These are technical documents which give much more information, diagrams, facts and figures to explain how it is possible to comply.

You can download copies of the Approved Documents and view associated guidance via the following links.
