In most cases, installing solar panels is considered to be permitted development and does not require planning permission providing it would meet the criteria set out below.
We always recommend making an application for a Lawful Development Certificate (Proposed Use or Development) to see whether their solar panels would need formal planning permission or not.
There is also guidance available for if you have already installed the panels.
Solar panels on homes and other domestic buildings
Solar panels are allowed on a house, block of flats, or on another building within their curtilage (usually the garden) if they do not:
- extend more then 0.2 metres beyond the plane of pitched roof slope or wall or 0.6 metres if the roof is flat
- extend no higher than the highest part of the roof.
They must:
- be sited to minimise effect on the appearance of the building
- not be installed on a wall which fronts a highway if the building is within a Conservation Area
- be located to minimise its effect on the look of the area
- be removed if the equipment which is no longer needed for microgeneration
- not be within the site of a schedule monument or listed building
Check if your property is in a conservation area.
Freestanding solar panels
Permitted if they are:
- no more than one array (block of panels)
- no more than 4 metres above ground level or if in a Conservation Area and closer to than the highway than your dwellinghouse 2 metres above ground level
- not within 5m of the curtilage boundary
- area of the panels does not exceed 9 square meters
- the area of an array of panels is not more than 3 square meters
- any dimension of an array of panels is not more than 3m
- not within the curtilage of a listed building or schedule monument.
Conditions:
- must be sited to minimise its effect on the appearance of the building
- equipment which is no longer needed for microgeneration shall be removed as soon as possible.
