Pitched Roof or Wall Mounted Solar Systems

The installation of a Solar system on the pitched roof or wall of a domestic building generally falls within permitted development rights providing the system does not protrude more than 200mm from the roof/wall surface.  However there are two exceptions:

  • If the building is listed you will need to apply for planning permission.
  • If the building is in a conservation area or area of outstanding natural beauty, you will need to check with your local planning office to see if planning permission is required.

Non-domestic systems on a pitched roof or wall also fall within permitted development rights.  The system must not protrude more than 200mm from the roof/wall surface and it must also be more than 1m from the external roof edge.  The exceptions here are as follows:

  • If the building is listed you will need to apply for planning permission.
  • If the building is in a conservation area or area of outstanding natural beauty, the solar system cannot be on a roof area or wall which faces a road.

Flat Roof Mounted Solar Systems

Domestic flat roof mounted systems require planning permission.

Non-domestic flat roof mounted installations do no require planning permission providing the system is less than 1m in height above the highest part of the flat roof (excluding chimneys) and it is more than 1m from the external roof edge.

Ground Mounted Solar Systems

Domestic ground mounted installations will require planning permission and may be subject to certain requirements regarding the siting of the ground array.

Non-domestic ground mounted installations up to 9m2 and 4m high are permitted providing the array is not sited within 5m of any boundary and is not nearer to a road than any part of the property’s buildings.

General Conditions – Non-Domestic

In all cases, solar equipment should be sited so as to minimise the effect on the external appearance of the building and the amenity of the area.

 

Regardless of the above, if there is any doubt, we will check with your local planning department on your behalf before installing a Solar system.
