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.

How can reasonable distribution of cost support the decarbonisation of heat?
We all have a role to play in meeting climate targets. The reasonable distribution of the cost of decarbonisation of heat could support a smooth transition to a low carbon economy. A considered approach could help navigate issues around fuel poverty and accelerate the uptake of a low carbon solution.
What are the installation options for a ground source heat pump (GSHP)?
There are three installation options with a GSHP; each one requiring slightly different considerations. These options are trenches, boreholes and installations next to large bodies of water, such as lakes.
A common requirement with all of them, however, is the need for internal space to install the buffer tank and water cylinder. A GSHP requires a network of coils to be buried underground or submerged in a body of water, where it can draw heat energy used by the heat pump to meet the energy needs of the building.
Amending the Planning and Energy Act - what could this mean?
During the recent Future Homes Standard consultation, Government published their intentions to amend the Planning and Energy Act 2008 during 2020 or 2025 - but what does this mean?
