The grace period for Part L building regulations has ended today, meaning the regulations are now legally enforceable
The Part L building regulations set the standard for energy efficiency and carbon emissions on both new and existing buildings. These regulations are applicable to stakeholders in the planning, construction, and refurbishment of buildings in England, including architects, builders, developers, engineers, and other building experts.
By now, house builders and developers must have ensured compliance with the Part L building regulations to create more low-carbon and energy-efficient homes in the UK. Contractors must provide evidence that they are adhering to the new regulations.
“It’s important not to underestimate the importance of photographic evidence, now an essential criterion to achieve Part L compliance. Contractors and developers should take the necessary steps to communicate this across all site teams, regardless of whether the project is underway or due to commence. They will need to take high-quality images at every stage of the building to prove the correct protocol has been followed,” said Steve Callow, housing manager at MPA Masonry.
Stakeholders will need to adapt to sustainable methods of construction
Many developers have already been able to meet the fabric-first requirements of the Part L building regulations. However, the use of alternative building methods is likely to be more challenging for construction stakeholders. This is due to heavier reliance on timber, glass, and metals, which have different thermal properties to concrete and brick.
“Now that the Part L grace period is ending, the message is clear to specifiers that they must select materials with sustainable outcomes in mind,” said Rob Norton, UK director of PlanRadar.
“This highlights the importance of the early design process – where the biggest impact can be made. It’s the perfect opportunity to choose materials that insulate, use less energy, and lower the carbon impact across the whole lifecycle of the building,” he continued.
The Part L building regulations will help improve efficiency
The Part L building regulations place a significant emphasis on adopting a fabric-first strategy for building performance. This approach offers a cost-effective way to reduce carbon emissions and improve energy efficiency throughout a building’s lifespan. It primarily centers around enhancing airtightness and insulation.
“The impact of Part L building regulations is far-reaching, particularly for manufacturers whose products have a direct impact on the energy efficiency of a building,” said Dr Stephen Hamil, innovation director at NBS.
“Manufacturers should see the changes as an opportunity – by supplying architects and engineers with the right type of product information, they can help them achieve lower carbon outcomes that will benefit all stakeholders,” he concluded.
