Planning Permission

We check that we have consent before beginning any work
If you are using roof space or an existing structure and you are not in a controlled zone then it is considered 'permitted development' under planning law with no need to apply for planning permission.

There are, however, a number of planning regulations that apply when you are considering any solar installation.

  • 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

Standard Building Regulations

If you wish to install solar panels on your roof, normal building regulations will apply with the addition of the Part P regulations covering direct electrical current installations.

You do not need to apply for planning consent to install solar panels unless they are mounted on the ground or they are on a flat roof and project further than 20cm above the roof line.

Modern solar panels are relatively lightweight so if your roof is reasonably sound then the original specifications should be sufficient to meet any building regulations. If there is a weakness then some strengthening work may be needed.


Building Regulations - Electrical Part P

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

Electricians need to be Part P registered. Part P Building Regulations cover the use of direct current electricity.

Wind Loading

We do the wind load calculations for every installation to check if there are any local problems, though this is not strictly necessary for most of the UK as climatic conditions are not too extreme.

Roof, Wall & Standalone Panels

Planning For Roof and Wall Mounted 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.
  • Wall mounted only - 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.

Planning For Standalone Solar Panels

  • Should be no higher than four metres
  • Should be at least 5m from boundaries
  • Size of array is limited to 9 sq m or 3m wide and 3m deep
  • Should not be installed within boundary of a listed building
  • In the case of land in a conservation area or in a World Heritage Site it should not be visible from the highway.
  • Only one stand alone solar installation is permitted.


Building Inspections

You can contact your Local Authority Building Control Office to tell them of your intention to install solar Photovoltaic Panels.

They will probably tell you that there is nothing that can be done until after the panels have been installed

A building control inspection of your roof is not necessary unlkess you are selling your home and transferirng ownership in which case you may be asked to prove the sound structural condition of the roof.

An inspection can cost a few hundred pounds but if you or the buyers are already having a structural survey carried out, then this need not be an extra cost.
