Approved Document H

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 (such as temporary buildings).
  • 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.

Approved Document H: drainage and waste disposal, was last published in 2015.

It provides guidance on providing adequate drainage, and also deals with pollution prevention, sewage infrastructure and maintenance. Technical design guidance covers sanitary pipework, foul drainage, rainwater drainage and disposal, wastewater treatment, and discharges and cesspools.
