Approved Document E
The first set of national building standards was introduced in 1965. Now known as the building regulations, they set out:
- What qualifies as 'building work' and so fall under the control of the regulations.
- What types of buildings are exempt.
- The notification procedures that must be followed when starting, carrying out, and completing building work.
- Requirements for specific aspects of building design and construction.
The 'approved documents' provide guidance for how the building regulations can be satisfied in common building situations. There is no obligation to adopt the solutions presented in the approved documents, the building regulations can be satisfied in other ways.
