Building Regulations Update

Building Regulations update Cheslyn Building Contractors

With the government having now published its updated Building Regulations for England which includes amendments to Approved Documents – Part F (ventilation), and Part L (Conservation of fuel and power), as well as the release of a new approved document for Overheating (Part O), we welcome these new regulations which are set to commence in June 2022, giving the industry six months to prepare for the new standards. 

What are Building Regulations?

Building Regulations establish a set of technical standards for the design and construction of buildings. If you’re building something new, or making big changes to an existing building, it is likely that you will need to comply with Building Regulations. Building Control Bodies will enforce these regulations to ensure that compliance is achieved.

When it comes to domestic properties, the building regulations are a set of standards that are designed to ensure that new buildings, renovation work, alterations, extensions and conversions are carried out in a manner that results in safe, energy efficient and healthy homes. There are in-depth sets of regulations each relating to specific areas of construction, including structural performance, electrical and gas safety, drains, ventilation and fire safety.

When it comes to commercial properties, the same applies. Under the building regulations, you normally require building consent for major building works: for example, new construction, significant extensions or structural alterations. Changing  the use of premises can also require building control approval: for example, to ensure that the building meets relevant fire safety requirements. All new residential buildings, including homes, care homes, student accommodation and children’s homes, must also be designed to reduce overheating. Improvements to ventilation are also being introduced to support the safety of residents in newly-built homes and to prevent the spread of airborne viruses in new non-residential buildings.

What has changed?

This update to regulations provides an intermediate uplift to existing energy efficiency standards. It’s a stepping stone towards the government’s new Future Homes Standard (due to be introduced in 2025) which aims to future proof new buildings with low-carbon heating systems and “world leading levels” of energy efficiency. The changes are as follows:-

  • 30% reduction of carbon emissions in new builds
  • 27% cut on carbon emissions in new non-domestic buildings
  • Overheating prevention in new residential buildings
  • Improvements to ventilation
  • Fabric Energy Efficiency Standard (FEES)
  • Maximum flow temperature requirement of 55°C

All new residential buildings, including homes, care homes, student accommodation and children’s homes, must also be designed to reduce overheating. Improvements to ventilation are also being introduced to support the safety of residents in newly-built homes and to prevent the spread of airborne viruses in new non-residential buildings.

The changes focus on greater fabric performance, lower energy demand, and a move away from fossil fuels to electric systems. The new sections of the building regulations will now also look at mitigating overheating risk and provide facilities for electric cars.
