Solar panels

Planning Permission

Roof and wall-mounted solar panels

In many cases fixing solar panels to the roof of a single dwelling house is likely to be considered 'permitted development' under planning law with no need to apply for planning permission.

There are, however, important exceptions and provisos which must be observed.

These permitted development rights apply to houses. If you live in a flat and are considering fitting solar panels you are advised to contact your LPA for guidance.

Roof and Wall Mounted Solar Panels are subject to the following conditions:

  • Panels on a building should be sited, so far as is practicable, to minimise the effect on the appearance of the building
  • They should be sited, so far as is practicable, to minimise the effect on the amenity of the area
  • When no longer needed for microgeneration they should be removed as soon as possible
  • Panels should not be installed above the ridgeline and should project no more than 200mm from the roof or wall surface
  • If your property is a listed building installation is likely to require an application for listed building consent, even where planning permission is not needed
  • If your property is in a conservation area, or in a World Heritage Site planning consent is required when panels are to be fitted on the principal or side elevation walls and they are visible from the highway. If panels are to be fitted to a building in your garden or grounds they should not be visible from the highway

Standalone solar panels

Standalone solar panels are permitted development, provided that they comply with the following conditions:

  • Only one standalone solar panel is permitted
  • No part of the installation must exceed 4 metres in height
  • If the panel is within 5 metres of the boundary of the property, it cannot be more than 2 metres in height
  • The panel shall not be within 5 metres of the highway
  • No dimension of the panel should be greater than 3 metres
  • The panel surface shall not be more than 9 square metres
