Building Regulation Updates

From 15th June 2022, new Building Regulations come into force in England which will help the built environment meet the net zero targets set by Government for 2050.

The changes are limited to Approved Document F (Ventilation) and L (Conservation of Fuel and Power), and also the creation of two new documents;

  • Approved Document O (Overheating)
  • Approved Document S (Infrastructure for the charging of electric vehicles).

The new regulations will have a transition period. If a building notice or full plan application has been submitted to a local authority prior to 15th June 2022, and the building work commences before the same date in 2023, the new regulations will not apply.

All applications beyond 15th June 2022 will be required to achieve the new standards.

Part F:

Requires the ventilation in existing buildings to be maintained or improved when energy efficiency work is carried out, and guidance is provided with all installations of mechanical extract ventilation.

Part L:

Improves the U value requirements for walls, windows, roof lights and doors to improve the thermal efficiency of domestic buildings and requires the SAP method of compliance for extensions to existing properties.

Part O:

Aims to reduce overheating in new residential buildings by minimising solar gain and removing excess heat from new developments. This will be achieved by considering cross-ventilation, orientation and the amount of glazing.

We have undertaken CPD to understand the technical changes of the Building Regulations and what it means for our practice and our clients.
