Part L of the UK Building Regulations sets out the requirements for the conservation of fuel and power in buildings. It covers both new build and existing buildings, and applies to all types of buildings, including homes, offices, schools, and hospitals.

The aim of Part L is to reduce the amount of energy used by buildings, and to help to improve air quality. The requirements in Part L are set out in a series of Approved Documents, which provide guidance on how to meet the standards.

The requirements in Part L are constantly being updated, and the latest version came into force on 15 June 2022. The changes in the latest version of Part L are designed to make buildings even more energy efficient, and to help to reduce carbon emissions.

Some of the key changes in the latest version of Part L include:

  • A requirement for all new homes to be 31% more energy efficient than homes built to the previous standards.
  • A requirement for all new non-residential buildings to be 20% more energy efficient than buildings built to the previous standards.
  • A requirement for all new buildings to be equipped with smart meters, which will help to people to monitor their energy use.

The requirements in Part L are enforced by local authorities. If you are planning to build a new building or make significant changes to an existing building, you will need to make sure that you comply with Part L. You can find more information about Part L on the government website.

Here are some of the things that you can do to make your home more energy efficient and comply with Part L:

  • Install insulation in your walls, roof, and floors.
  • Install double or triple glazing.
  • Choose energy efficient appliances.
  • Seal up any draughts around doors and windows.
  • Consider installing a renewable energy system, such as solar panels or a heat pump.

By making your home more energy efficient, you can save money on your energy bills, and help to protect the environment.
