Building Regulations in England & Parts L, F and O
With the transitional period now over, the updated 2022 Building Regulations Part L, Part F, and the new Part O, became legally enforceable for all new residential projects.
This is the biggest regulatory change the construction sector has seen in the last 40 years and a stepping stone in our transition away from fossil fuel systems toward decarbonised homes and the electrification of heat - and ultimately, the Future Homes Standard. This shift will impact the way we design buildings and specify technologies.
Have you decided which technologies to specify to achieve compliance for your next residential project?
The new English Building Regulations came into law on the 15th of June 2021. For projects with existing planning permission there is one year transitional arrangements period that applies on plot-by plot basis.
The updated Part L outlines the four compliance metrics for new developments: primary energy target, carbon emissions target, fabric energy efficiency target, and minimum standards for building fabric and building services.
The ventilation system choice under the updated Part F is linked to aritightness as we look to increase indoor air quality. New Part O offers modelling to help mitigate the risk of overheating in buildings.
We designed a simple guide to the changes to Part L and Part F, and the new Part O, and discuss what they may mean for your project.
Our range of HVAC solutions aim to provide future proof technologies to building projects over various sectors.

Our news section cover building regulations, what the changes to Part L, F, and the new Part of O entail, and what this means for HVAC specification.
Residential ventilation: Saving time on design and installation
The importance of suitable ventilation is becoming increasingly recognised, as society and the media have begun to focus on the air quality within our homes. This is because as Part L of the Building Regulations has been updated to save energy by tightening the building fabric, Part F has not been reviewed in turn. This has resulted in poor air quality as air change requirements do not go far enough to remove volatile organic compounds (VOCs) from residential spaces.
Residential Housing: Alternative HVAC Solutions
At GDHV, we are often asked about alternative HVAC solutions for residential housing. When considering current legislation, regional targets and the requirements of housebuilders, we usually suggest the Edel hot water heat pump.
Proposed compliance metrics for Part L 2020
Government’s Future Homes Standard consultation closed early last month, leaving industry with no doubt that HVAC specification is about to change. One of the biggest changes is the proposal of four compliance metrics for new developments which will impact new HVAC strategies.
