Firstly, what is Part L?

Part L is a building regulation that covers the ‘Conservation of Fuel and Power’ concerning both new construction projects and some refurbishment work, for dwellings and other buildings in England. It sets the standard for current and future energy performance and carbon emissions, which for the UK are a target of net zero greenhouse gas emissions by 2050, with any energy produced by fossil fuel offset by renewable resources.

Whilst highlighting the need to tackle the damaging effects of traditional energy sources upon the environment, managing the carbon footprint for new build construction and the refurbishment of the UK’s current housing stock is seen as a key driver to reaching the net zero goal.


Part L: is the construction sector ready?

The journey towards a net zero future continues to gain momentum. As a result, how the construction sector imagines and constructs the homes and buildings we live and work in is set to play a pivotal role in meeting the Government’s 2050 target.

2022 marks the next milestone on the journey. Changes to Part L of the Building Regulations become a reality and will provide the new benchmark for the design and building standards for energy performance and carbon emissions of new and existing buildings.

We recently conducted research among more than 200 important stakeholders, including architects, housebuilders and specifiers. Using this insight, our exclusive report – Part L: Is the construction sector ready? assesses current knowledge of, and preparation for, the uplift to Part L among those charged with implementation and delivery of low carbon and energy efficient housing.

Investigating levels of Part L ‘confidence’ across the sector, views on sustainable technologies such as solar PV, and highlighting the primary challenges the industry faces, the report sets out compelling insight about what the sector thinks and plans to do as the Part L changes loom large.
