Review of Welsh Building Regulations Part L and F: Stage 2B

Closing date: 17 January 2022

Objectives of the consultation

This is the final stage of a three-part consultation about proposed changes to the Building Regulations, which set out a pathway towards creating buildings that are fit for the future, and a built environment with lower carbon emissions and homes adapted to the overheating risks caused by a warming climate.

This consultation builds on the previous Stage 1 and 2A consultations by setting out energy and ventilation standards proposed to be implemented from 2022 for new and existing nondomestic buildings. It also includes further proposals (in addition to the stage 2A consultation) for a new standard to mitigate against overheating in new residential buildings, which is proposed to apply to domestic buildings as well as some non-domestic buildings which provide residential accommodation. Taken together with the previous 2 consultations, the proposals in this document form a complete set of ambitious new energy and ventilation standards to apply across the built environment.
