This page explains what permission may be required for ground source heat pumps/water source heat pumps, biomass or combined heat and power and small hydro electric systems
Pumps/water source heat pumps - Planning permission is not needed to install a ground or water source heat pump, but may be required if you need to construct a building or extension to accommodate it. You may need consent if your house is a listed building.
You will require building control consent and the installation will also need to comply with Part P of the building regulations.
Biomass or combined heat and power system - You do not need planning permission to install a biomass or combined heat and power system but may need permission if you need to construct a building or extension to accommodate it
You do not need permission to install, alter or replace a flue serving this type of heating system providing it is no more than 1m higher than the highest part of the roof.
If you live in a conservation area you will need permission if the flue is on a wall or roof slope visible from a highway. If your house is listed you will need to apply for listed building consent. Building control consent is required.
Small hydro electric system - Whether or not planning permission is required depends on the particular nature of the proposal. You may need permission if you need to construct a building or extend your home to accommodate it. You may also need listed building consent if your property is listed.
Building regulations consent is not normally required unless you need to extend your home to accommodate it. However all small hydro electric installations will need to comply with building regulations part P (electrical).
Further information is available from the planning portal website
You need planning permission if your house is within a conservation area. If it is listed, you will also need to apply for listed building consent.
Otherwise, for turbines fixed to a house you not need planning permission if the turbine will be no higher than the highest part of the roof nor exceed 4m in height if located within 2m of the boundary.
Free standing turbines do not require planning permission providing they are less than 3m high overall (including any mounting or pole) and are not located between the house and the highway.
Do I need building control consent? A building control application is required when a wind turbine is to be attached to a building as we will need to check the existing structure can support the turbine. Building regulations also apply to other aspects of the work such as electrical installation (part P). The installer should be able to provide the necessary advice.
About wind turbines Small scale wind turbines and a battery storage system can reduce the need to draw electricity from the grid, but is unlikely to replace external supplies altogether. Think about:
- technical advice on wind speeds and payback times
- structural considerations if it is to be mounted on a building
- noise impact on neighbours, and the
- impact on the landscape or character of the building
