Recticel Insulation has produced a comprehensive guide to the updated Part L Building Regulations.

'The Road to Net-Zero', which sets out in clear, concise terms the amended regulations’ details and aims, is free to download via the leading PIR board manufacturer's website.

Building Regulations Part L covers the conservation of fuel and power in the building of new homes in England and sets the energy performance standards of existing buildings.

Introduced in June 2022, the milestone legislation advocates a fabric-first approach to building design and the use of renewable technologies as being key to reducing the CO2 output of new dwellings by 31% compared to current standards.1


The regulation's uplift is a steppingstone to the Future Homes Standard, which will require new homes to produce 75-80% fewer carbon emissions than properties built to the previous standard.

Simon Blackham, Technical Manager at Recticel said: "The amended Part L regulations are crucial to improving the energy efficiency of new homes. Hence our release of The Road to Net-Zero. As one of the UK’s leading insulation manufacturers, we believe it's our shared duty to help raise building standards. This is not only in respect of the innovative products we produce, but also in relation to the professional knowledge we impart to industry stakeholders. The Road to Net-Zero is indicative of our overarching aim."

The 20-page 'Road to Net-Zero' guide was created using insights provided by Recticel’s knowledgeable technical team. It is essential reading for anyone looking to gain a better understanding of how the updated Part L energy standards apply to buildings in England, Wales, and Scotland (where Section 6 applies). The guide also showcases a range of PIR products specifically innovated by Recticel to meet the regulations’ revised U-Value requirements and optimise fabric-first building design. In addition, there is an overview of the Future Homes Standard’s anticipated energy targets.
