Changes to Part L Building Regulations from ARC Building Solutions
Do you know about the latest changes to Part L Building Regulations?
The changes are part of the Government’s step toward its target to deliver Zero Carbon Ready Homes by 2025.
From 15th June 2022, all new homes must produce 31% less CO2 emissions than what is currently acceptable in the present Part L regulations. Therefore, the construction of new dwellings must comply with the increased energy performance standards as set in the new regulations.
An on-site audit will be required to confirm that the designed details have been constructed, and photographs must be taken as evidence to form the BREL report.
What is Thermal Bridging? Why is it a concern for CO2 emissions?
A “thermal bridge” (also known as a “cold bridge”) is a disruption in a building’s thermal wrapping, such as a gap in insulation. Thermal bridging causes heat loss and condensation.
Heat loss has a significant impact on the energy efficiency of a building, making this a crucial problem to target to reduce CO2 emissions.
How can Thermal Bridging be reduced?
Insulation must be continuous. This applies to areas such as walls, roofs, windows & doors, and the junctions between these areas.
For example: Roof insulation should be continuous with wall insulation. The regulations advise that “opportunities should be considered to use products that help to reduce thermal bridges”.

These new Part L Building Regulations, are designed to improve the energy efficiency of new buildings in the UK, contributing to the country’s broader goals of reducing carbon emissions. While these regulations offer significant benefits, they also present challenges that builders, developers, and homeowners need to consider.
Advantages
One of the primary advantages of the new Part L regulations is their contribution to energy efficiency and sustainability. By setting higher standards for thermal insulation, air tightness, and energy-efficient technologies like heat pumps and solar panels, these regulations ensure that new buildings consume less energy. This not only reduces greenhouse gas emissions but also lowers energy bills for homeowners and businesses, making properties more affordable to operate over the long term. The regulations also encourage the adoption of renewable energy sources and advanced building materials, driving innovation in the construction industry and helping the UK move closer to its net-zero carbon goals.
Additionally, buildings that comply with the new Part L regulations are likely to have a higher market value. As energy efficiency becomes an increasingly important consideration for buyers, properties that meet these standards are more attractive and can command higher prices. This can be a significant advantage for developers and investors in the real estate market.
Disadvantages
However, the new regulations also come with disadvantages. The higher standards for insulation and energy efficiency can lead to increased construction costs, as builders may need to invest in more expensive materials and technologies. These costs are often passed on to consumers, making new homes and buildings more expensive. For smaller builders, these additional costs could be particularly burdensome, potentially reducing their competitiveness in the market.
Moreover, the complexity of meeting the new standards could result in longer construction times and increased administrative burdens. Ensuring compliance with the detailed requirements can be challenging, particularly for those unfamiliar with the latest building technologies. This could lead to delays in project completion and potential legal challenges if buildings are found to be non-compliant.
In summary, while the new Part L Building Regulations represent a positive step towards greater energy efficiency and sustainability, they also present financial and logistical challenges that need careful management.
