Council for Aluminium in Building

Part L Technical Briefing

“…as we know, there are known knowns; there are things we know we know. We also know there are known unknowns; that is to say we know there are some things we do not know. But there are also unknown unknowns—the ones we don’t know we don’t know.”
Donald Rumsfeld.

Part L is changing as we strive to deliver buildings that are more energy efficient and reduce carbon emissions in use. We are seeing proposals across the UK and especially in England and Wales to make changes in 2022, with further changes planned in 2025 when the Future Homes Standard for new homes and the Future Building Standard for all other build types are expected to come into force.

Our current understanding of the proposals is set out in the following two tables. The government has responded to the Future Homes Standard consultation for England, and their response can be found here. The government is analysing feedback to the Future Buildings Standard consultation for England and the outcome will be published here.

These tables will be updated as further details are confirmed over the coming weeks and months. Still confused? Then join CAB and not only learn about these proposals in more detail but also help to shape them – help to direct the future of aluminium in building.
