Heat pumps & planning – the facts

A horizontal closed loop heat exchanger comprises a ‘slinky’ that runs in a ground trench.

Check if the ground works needed for a
ground-source heat pump need planning
permission.

For ground-source heat pumps, the external excavation works required for this type of system can be considerable. In a few cases this could mean that 'engineering operations requiring planning permission' rules may apply. If in doubt, we recommend that you (or your potential installer) contact your local authority to discuss the proposed installation works.

For both ground and air-source heat pumps, Building Regs Part L apply. This means that heat losses from all pipes, ducts and tanks must be minimised. Efficient system controls are also a requirement.

Many heat pump installations also contain 'notifiable' electric works which require Part P compliance. Your installer can advise on these requirements.

Heat pump planning tips:

  • Check out your local authority website for local information about planning issues. Search the site for 'renewable energy' if you can’t find the right page
  • Ask your installer for advice – especially if they are local!
  • Always consult your local authority for precise guidance if you live in a conservation area or a listed building.
