In England, changes to permitted development rights for microgeneration technologies introduced on 6th April 2008 have lifted the requirements for planning permission for most solar water heating installations. Roof mounted and stand-alone systems can now be installed in most dwellings, as long as they respect certain size criteria. See our planning permission for renewable energy technologies for more information. Exceptions apply for Listed Buildings, and buildings in Conservation Areas and World Heritage Sites.

 

In Wales, Scotland and Northern Ireland, the devolved governments are currently all considering changes to their legislation on permitted developments, to facilitate installations of microgeneration technologies, including solar water heating. Legislation is expected in all three countries later this year. Until then, householders in Wales, Scotland and Northern Ireland must consult with their local authority regarding planning permission.

 

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.

 

The following limits apply to roof and wall mounted solar panels:

 

• 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 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.

 

All solar installations are also 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.

 

 

Building Regulations

 

If you wish to install a solar panel on your roof building regulations will normally apply.

 

The ability of the existing roof to carry the load (weight) of the panel will need to be checked and proven. Some strengthening work may be needed.

 

Building regulations also apply to other aspects of the work such as electrical installation.
