Update to Approved Document L1B

by on April 19, 2018

Approved Document L1B and the Domestic Building Services Compliance Guide were both updated on 6 April 2018. The updated documents deliver guidance on compliance for building work carried out in England.

The changes apply in respect of:

  • Building notices given, full plans deposited or initial notices given on or after 6 April 2018
  • The contract for the provision of the work being agreed on or after 6 April 2018 in cases where no notification to a building control body is required.

Approved Document L1B is a building regulation for England, regarding the standard for energy performance of new and existing buildings.

The Domestic Building Services Compliance Guide is a document which supports Approved Documents L1A, L2A, L1B and L2B.

You can read some additional information on the changes below:

    This notice comes a bit late for projects that have already been granted planning and so have designs based on the previous editions.

      Well, the Local Authorities and Approved Building Inspectors got no pre-notice at all for these changes. Which really only affect existing buildings and “changes-of-use” work.
      As more “change of use” is now PD (does not require town planning consent) the government has said it is keen to ensure these existing buildings with new uses are more energy efficient.
