Part L Product Modelling

Part L Product Modelling 

Find out how your products and buildings perform against the new Building Regulations 

Part L of the Building Regulations changed in England in June 2022, with further measures scheduled for 2025. 

The update to the rules surrounding the conservation of fuel and power in new build homes will have far-reaching implications for manufacturers, installers and housebuilders, as homes built in 2025 will have 75-80% lower carbon emissions than houses built to current standards (with interim measures having been introduced in June 2022).

Make sure your houses meet compliance with the new (and upcoming) regulations with our Part L Product Modelling service.


Check if your houses meet compliance

Our expert team of energy consultants will use the latest government-approved software to model your house plans against the new Part L of the Building Regulations.

You'll be able to:

  • Find out how you products perform against current and future regulations
  • Identify potential improvements.
  • Compare your products against your competitors’.
  • Model your products in 8 different property archetypes.

We can also demonstrate the energy performance of your products in homes built to future Building Regulations, which you can include in your company's marketing and PR activities to help win more business.
