Building Regulations England Part L (BREL) Report

For residential building plans submitted to a Building Control body after 15th June 2022 there is now a requirement for a Building Regulations England Part L (BREL) report to be produced and for photographic evidence to be provided to the Building Control body and to the building owner to show that the building work complies with energy efficiency measures.

The BREL report will be carried out a by a competent Energy Assessor, however the photographs may be taken by either the developer, energy assessor or another individual.

Who will take the photographs?

Photographs need to be taken for each dwelling on a development, with each photograph requiring to be date stamped and geo-tagged. Each image will also need to reference the numbers used in paragraph B7 (see below).

How does it work in practice?

The following is the list of the typical details of construction taken from Approved Document Part L, Conservation of fuel and power, Volume 1: Dwellings Appendix B7:
