Latest changes to Part L Building Regulations – how they will affect your choice of windows and doors in new builds and updates to existing homes

Government changes to Part L of the Building Regulations in England come into effect on 15th June 2022. The aim of the changes is to reduce the amount of carbon emitted from our buildings and homes by 30%, compared to current levels of emission. These changes will implicate the design and construction of homes, including your choice of windows and doors. Westcoast supply a full range of energy efficient composite windows to meet these regulations.

(*Please note: Information provided in this new article is correct at the time of writing.)

This update is an improvement on existing energy efficiency standards for homes, and will be a stepping stone towards the Future Homes Standard planned for 2025.

The changes will apply to new homes, including self-build homes, and in existing homes standards have been raised to reduce energy use and carbon emissions during home improvements.

So how do the Part L changes apply to your choice of windows and doors for your new home?

  • From 15th June 2022, the U-values for windows and doors (>60% glazed) in new dwellings will be a maximum of 1.2 W/m2
  • The limiting U-value for a window has also been dropped from 2.2 W/m2k to 1.6 W/m2k.
  • Semi-glazed and opaque doors will be a maximum of 1.0 W/m2k.

 

How do the Part L changes affect updates to existing homes?

  • From 15th June 2022, the U-values for new windows in existing buildings will be 1.4 W/m2k or Window Energy Rating Band B minimum.
  • For Doors with up to 60% of internal face glazed the maximum U-value will be 1.4 W/m2k or Doorset Energy Rating Band C minimum.
  • Other doors will be will be 1.4 W/m2k or Doorset Energy Rating Band B minimum.

 

Westcoast Swedish aluminium timber composite windows for Part L Building Regulations

Westcoast design and manufacture Swedish high performance energy efficient aluminium timber composite windows. Our composite windows and doors conform to the new Part L Building Regulations with U-values as low 1.0W/m2k for opening windows and 0.9W/m2k for fixed windows.

Westcoast composite windows and doors are manufactured using sustainable methods following our strict environmental policy. They are constructed from a low maintenance aluminium exterior which is powder coated in a colour of your choice – no regular re-painting or treatment required (just a wash with a soft cloth). The inside of the window is real wood in pine, oak or a timber of your choice, finished in lacquer, paint or stained to suit your style. Westcoast composite windows and doors are built to last with an estimated lifespan of 50 years (subject to maintenance – see datasheet below).
