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.

What is diversity in HVAC systems?
What is diversity in HVAC systems, and how does it affect HVAC system design and specification for residential developments?
Diversity in HVAC systems within medium to large scale developments acknowledges that it is unlikely the maximum demand of all individual users of the system will arise concurrently. The total heat demand in a building is likely to be lower than the maximum or peak demand at various points in the heat network.
What is COP and EER?
The Coefficient of Performance (COP) and Energy Efficiency Ratio (EER) are measures of a heat pump or heating and cooling solution’s efficiency. They indicate a ratio of useful heating or cooling produced by the unit against the energy it consumes. For example, the COP of a heat pump that can provide 3kW of heat against the input of 1kW of electricity is 3. The EER that generates a cooling effect of 12BTU against the input of 1kW of electricity is 12.
What Building Regulations are changing during 2020?
2020 has been dubbed the year of change for the built environment, with Government keen on updating compliance targets for new and existing dwellings to enforce change in industries HVAC strategies.
