New Regulations for Installing Air Source Heat Pumps Effective from May 29, 2025

As of May 29, 2025, the UK government has introduced significant changes to the planning regulations surrounding air source heat pumps (ASHPs) in England. These updates are part of the broader Warm Homes Plan, which aims to simplify the installation process. The ultimate goal is to encourage the adoption of low-carbon heating solutions.

Key Policy Changes for Air Source Heat Pumps:

• Removal of the 1-Metre Boundary Rule: Homeowners previously required planning permission to install an ASHP within one metre of a property boundary. This restriction has been removed, making installations easier for properties with limited outdoor space, like terraced homes.

• Increased Size Limit: The maximum size for an ASHP that can be installed without planning permission has increased. It now allows up to 1.5 cubic metres instead of the previous limit of 0.6 cubic metres. This change permits the installation of larger and more efficient units.

• Allowance for Multiple Units: Detached homes may now install up to two ASHP units under permitted development rights. This allows for the use of cascade systems, effectively meeting higher heating demands.

• Inclusion of Air-to-Air Systems: Air-to-air heat pumps, which also provide cooling, are now included under permitted development rights, provided they are not used solely for cooling purposes.

  
  

Noise Compliance

While the spatial restrictions have been loosened, strict noise compliance rules remain in effect. ASHPs must adhere to the updated MCS 020 standard. This ensures that noise levels are kept within acceptable limits to avoid disturbing nearby properties.

Financial Incentives

The Boiler Upgrade Scheme continues to offer grants of up to £7,500 to promote the installation of heat pumps. With the removal of previous planning barriers, this scheme is now more accessible. Homeowners who faced challenges due to spatial constraints can benefit from financial support.

The Impact of These Changes

These regulatory changes are expected to boost the adoption of heat pumps throughout England. By simplifying the installation process and providing financial support, the government aims to increase low-carbon heating accessibility for a wider range of households.

Broader Environmental Goals

The overarching aim of these changes is to contribute to the UK's commitment to reducing greenhouse gas emissions. By facilitating more efficient heating solutions, these regulations align with global climate goals.

Community Benefits

The transition to heat pumps also offers community benefits. As more households adopt ASHPs, the demand for fossil fuels decreases. This shift can lead to improved air quality, reduced energy costs, and enhanced energy security for communities.

Future Considerations

While these changes are a positive step forward, it is essential to monitor their implementation closely. Local councils and homeowner associations may still have specific restrictions. It is advisable to check with local authorities to ensure compliance with all relevant regulations.
