With the growing focus on sustainable home heating, air source heat pumps (ASHPs) have become a popular option for homeowners. A common question when considering installation is whether planning permission is required. Thanks to the UK government's Warm Homes Plan 2025, the rules around ASHP installation are changing to make the process easier.
Planning Permission Today
Currently, ASHPs in England are often treated as "permitted developments," meaning planning permission is not required if certain conditions are met. These conditions include:
- Installation on a domestic property.
- Placement at least one metre from the property boundary.
- Compliance with noise and size regulations.
- Avoidance of designated areas like conservation zones or listed buildings.
Homeowners are still advised to check with local authorities to ensure compliance with these rules.
How the Warm Homes Plan 2025 Changes Things
From early 2025, new provisions in the Warm Homes Plan will remove the rule requiring air source heat pumps to be installed at least one metre from a property boundary. This adjustment is a significant step forward, simplifying the installation process for many homes, especially those with smaller gardens or less outdoor space.
The change reflects the government's commitment to achieving net-zero emissions by 2050 by making renewable technologies more accessible. Alongside this reform, the plan includes financial incentives and support to help households transition to sustainable heating systems.
Why This Matters
The removal of the one-metre boundary rule eliminates a common barrier for many homeowners, allowing more properties to install ASHPs without the need for a formal planning application. This means faster, less complicated installations, and greater adoption of this eco-friendly technology.
Key Considerations for Homeowners
While the changes will make installation easier, it’s still essential to:
- Ensure the unit meets noise and efficiency standards.
- Check specific requirements if your home is in a conservation area or a listed building.
- Work with accredited installers who can provide guidance on planning and compliance.
