Details

This impact assessment informs the government’s Future Homes Standard consultation. Specifically, it looks at the changes to Part L - conservation of fuel and power, and Part F - ventilation of the Building Regulations for new dwellings.

The consultation presents two options to update the current Part L energy efficiency standards in 2020 for new homes. It also considers the wider impact of Part L for new homes, including changes to Part F (ventilation), airtightness, improving as built performance and changes to transitional arrangements in 2020.

This impact assessment only details the impacts of changes to new dwellings. A further consultation and impact assessment will be published in the coming months which will include changes to Part L and Part F for existing homes, Part L and F for new and existing non-domestic buildings and overheating in new homes.

This impact assessment does not consider the costs and benefits of the Future Homes Standard. Before the Future Homes Standard is introduced in 2025, the government will consult on the full technical details and produce an associated impact assessment.
