» IN A MOVE TOWARDS achieving the Future Homes Standard in 2025 , changes in Part L came into effect in June 2022 . 18 months on , an Industry Viewfinder survey by Housebuilder & Developer ( HBD ) reveals over three-quarters ( 77 %) of UK housebuilders find the new regulations challenging .

The report , ‘ A Year On : Revisiting Changes to Part F & Part L ’, was commissioned by HBD in association with a number of key industry manufactures including Keylite Roof Windows ( Keylite ). It explored UK housebuilders ’ attitudes to the changes and the impact the new regulations had made on projects and buying habits .

The modifications to Part L include guidelines for the energy performance of roof windows , ensuring housebuilders specify appropriate glazing and insulation standards to minimise heat loss in all projects .

In accordance with Part L specifications , Keylite ’ s patented expanding thermal collar is integrated to maintain the window ’ s thermal integrity .

This provides housebuilders with a cost-effective and time-efficient solution to create thermally efficient and comfortable homes .

Colin Wells , Head of Technical at Keylite , comments : “ This latest study from HBD is very enlightening . It shows that over half ( 55 %) of UK housebuilders found addressing Part L specification in relation to window U-values quite challenging , whilst almost a third ( 30 %) found a cost increase of 1k-5k per unit due to Part L updates .

“ Interestingly , the study also revealed that 72 % of housebuilders said having a thermal collar installed alongside a roof window is ‘ important ’ or ‘ very important ’. Keylite ’ s patented

Integrated Expanding Thermal Collar comes as standard in every roof window , improving airtightness and Psi Values for SAP . It also ensures the thermal integrity of the window and roof is as designed , thus removing the reliance on an additional thermal collar , helping housebuilders meet Part L regulations .”
