The 2021 update to the Part F Building Regulations is due to take effect from 15th June 2022.  

Approved Document F is split into two volumes; Volume 1 covers dwellings; Volume 2 covers buildings other than dwellings

Part F of the Building Regulations is very closely linked with Part L (conservation of fuel and power) as both are being improved to meet the Governments Future Homes Standard.

One way of improving energy efficiency is to reduce the heat loss through air permeability, this means building more air tight homes. However, an increased air tightness leads to reduced ventilation and therefore Part F has been updated to ensure that sufficient levels of ventilation are still provided.
