Do I need planning permission?

Solar panels on a house or block of flats

There are presently two types of solar panel available for domestic use - photovoltaic (PV) and thermal.

Solar thermal systems: A solar thermal system uses the sun's energy to warm a heat conductive fluid that passes through panels usually located on the roof of a building. The heat energy collected is then passed though a heat exchanger into a tank of stored water thereby raising its temperature. The warmed water is then fed into your domestic boiler where additional heat is added if neccesary and then on to your taps etc. 

Photovoltaic systems (PV): A photovoltaic system converts the sun's light energy directly into electricity which is then fed into your domestic electrical system. Whilst contributing to your home's energy demands effective photovoltaic panels have the potential to generate a surplus supply of electricity which can be sold to the national grid to generate an income. Government backed Feed-In Tarriffs (FITs) are available for those looking to sell electicity back to the grid.

Further details of this, together with other ways to help reduce your home's impact on the environment can be found on the Council's Climate Change: Residents section.

In planning terms both systems are viewed in the same way, and the following rules apply.

Do I need planning permission?

As of 1 December 2011 if you want to install, alter or replace solar (photovoltaic or thermal) equipment on a dwellinghouse or block of flats (see definitions below) or on a building located within the curtilage (boundary) of a dwellinghouse or block of flats;

Planning permission will not be required as long as:

 
 






 
The equipment does not protrude more than 200 millimetres (mm) from the plane of the roof slope or face of a wall (when measured perpendicularly/out at a right angle from the face of that roof or wall slope
 
The equipment is no higher than the highest part of the roof (excluding the chimney)










Note: If you are intending to install solar panels onto a flat roof please remember that they cannot protrude more than 200mm from the plane of the roof, therefore if you plan to mount the panels at an angle you will most probably need planning permission. Please refer to illustrations for more details.

Additional site specific restrictions

In addition to the above criteria there are still site specific restrictions that may apply to your residential property. You can use our online mapping service to check to see if these restrictions apply to your property.
 

If your property is located within a Conservation Area, the equipment must not be located on a wall which fronts a highway (road or footpath).
 
Solar panels must not be placed on a site is designated as a scheduled ancient monument or forms part of the curtilage of a listed building.
 

Conditions

If your proposed turbine meets all of the above criteria you do not need to apply for planning permission before you install the device, however there are still a number of conditions that apply. These are as follows:

It shall be sited as far as practicable so as to minimise effect on the external appearance of the building
  
It shall be sited, as far as practicable so as to minimise the effect on the amenity of the area
  
The equipment shall be removed when no longer in use
 

What next?

If you are looking to be able to sell any excess electricity generated back to the national grid you will need to be registered on a Feed-in tariff (FITs). In order to be able to be eligible for the Feed-in Tariff your system must be installed by an MCS accredited installer. To search for an MCS approved installer you can refer to the MCS Installer Search page. For more general information and guidance on installing solar panels please refer to the Energy Saving Trust website.
