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.

Preparing HVAC specification for Option 1 and Option 2
For the 2020 update to Part L of the Building Regulations, Government decided to ask industry how challenging they wanted the uplift in energy efficiency standards to be. They did this by offering two options during the recently closed consultation. Both will impact HVAC specification – but how do you prepare for either one becoming law?
Pre-Release Statement: Spring Statement 2019
Today, Wednesday 13th March 2019, the Chancellor of the Exchequer, Philip Hammond will present the Spring Statement to Parliament. It is expected that this will announce the introduction of a Future Homes Standard and address the growing need for energy efficient solutions.
Part l update 2019 building compliance primary energy
The upcoming Part L and Part F updates are likely to change the way new developments achieve compliance, as primary energy becomes the key metric for energy performance targets. This change could heavily impact heating, ventilation and air conditioning (HVAC) specification and building design. This is why we have created our new reports:
