Permitted Development Rules for a Ground Source Heat Pump
Generally permitted under Part 14, Class H of the GPDO. Ground source heat pumps are PD when installed within the curtilage of a dwelling. The ground must be reinstated after installation.
Conditions
- 1Must be installed within the curtilage of the dwelling
- 2The land surface must be reinstated to its previous condition after installation
- 3Must not be on land within the curtilage of a listed building
- 4Equipment above ground (pumps, manifolds) must comply with standard outbuilding PD rules if in a separate enclosure
Size and Dimension Limits
- No specific dimensions for the underground pipework
- Above-ground equipment: follow outbuilding rules if housed in a separate structure
When Permitted Development Does Not Apply
- Not PD within the curtilage of a listed building
- Vertical boreholes may require an environmental permit from the Environment Agency depending on depth and local geology
- Ground conditions must be suitable (assessed by an MCS-certified installer)
- The ground must be reinstated afterwards
What About Building Regulations?
Building regulations approval is likely required
Building Regulations apply to the heating system installation. Covers Part L (energy efficiency), Part P (electrical), and the integration with the existing heating system. An MCS-certified installer can self-certify the work. MCS certification is required 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 Wokingham building control or use an approved inspector.
How to Apply in Wokingham
If you need planning permission for your ground source heat pump, you can apply through Wokingham'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 Wokingham. 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?
Very low planning enforcement risk as the installation is almost entirely underground and invisible once complete. The main regulatory risks are environmental (contamination of groundwater) rather than planning.
