June 2022, new Building Regulations in England & Parts L, F and O

With the transitional period now over, the updated 2022 Building Regulations Part L, Part F, and the new Part O, became legally enforceable for all new residential projects.

This is the biggest regulatory change the construction sector has seen in the last 40 years and a stepping stone in our transition away from fossil fuel systems toward decarbonised homes and the electrification of heat - and ultimately, the Future Homes Standard. This shift will impact the way we design buildings and specify technologies.

Have you decided which technologies to specify to achieve compliance for your next residential project?
