Existing Non-Dwellings
The Part L 2021 consultation process has commenced with proposals being released for new dwellings. The corresponding proposals have yet to be issued for existing buildings other than dwellings (e.g. offices, retail, etc.), but we are expecting major changes to the requirements of replacement windows and doors.
The consultation on proposed changes for existing buildings other than dwellings are anticipated in accordance with the following timeline:
