Permitted Development Rules for an Air Source Heat Pump
Generally permitted under Part 14, Class G of the GPDO. One air source heat pump is permitted per property, subject to conditions on size, noise, and position. The unit must comply with MCS planning standards for noise.
Conditions
- 1Only one heat pump per property under PD
- 2Must comply with MCS planning standards (MCS 020) for noise
- 3Must be at least 1m from the property boundary
- 4Must not be installed on a wall or roof slope fronting a highway (that is the principal or side elevation in designated areas)
- 5Must not be on a building listed or within the curtilage of a listed building
- 6Unit must be removed when no longer needed
Size and Dimension Limits
- Maximum volume of the unit: 0.6 cubic metres (including housing)
- Must be at least 1m from the property boundary
When Permitted Development Does Not Apply
- Not PD for listed buildings or within the curtilage of a listed building
- In designated areas, the unit must not be on a wall or roof forming the principal or side elevation visible from a highway
- Noise is a key consideration; complaints from neighbours can lead to a statutory nuisance investigation
- Only one ASHP per property under PD; a second requires planning permission
What About Building Regulations?
Building regulations approval is likely required
Building Regulations apply to the heating system installation. Covers Part L (conservation of fuel and power, including system efficiency), Part J (combustion appliances, if replacing a gas boiler), and Part P (electrical installation). Work should be carried out by an MCS-certified installer to qualify for the Boiler Upgrade Scheme grant.
Building regulations are separate from planning permission. Even if your project is permitted development, you may still need building regulations approval. Contact Gedling building control or use an approved inspector.
How to Apply in Gedling
If you need planning permission for your air source heat pump, you can apply through Gedling's planning department or via the national Planning Portal.
If your project is permitted development and you want written confirmation, you can apply for a Lawful Development Certificate (LDC) from Gedling. This provides proof that your project does not need planning permission, which can be helpful when selling your property.
What Happens If I Build Without Permission?
Low risk if installed within PD conditions. The most common issue is noise complaints from neighbours, which are dealt with under environmental health (statutory nuisance) legislation rather than planning enforcement. Installing a second ASHP without PP could attract enforcement.
