If you own a residential property, it’s likely that you have considered installing Solar or at least done some research into the technology over the last 18 months. This is in line with the rise of energy costs since 2022, exploring renewable energy methods as a way to reduce your monthly utility bills. A question that a lot of people have is whether or not planning permission is required to have Solar Panels installed.
The answer, for most properties, is no. Solar Photovoltaic panel installation falls under permitted development in the United Kingdom, meaning that homeowners can carry out improvement or extension works to their homes, without the need to make a planning application.
Instances where planning is required
Should your property be a flat, listed building or sit within a conservation area, you may need to make a planning application. If you are intending to have Solar installed on a flat roof, you may also need to make an application.
Installations on flat roofs are more widely accepted and placed under permitted development, since alterations to the planning regulations in late 2023. This means that a flat roof section attached, detached or on an outbuilding can have PV installed without seeking permission.
In a scenario where your flat roof or roofs sit at the same height as the tallest roof section on the property, you must adhere to strict regulations on the overall height of the Solar PV system. Once mounted, the panels must not sit more than 200mm above the ridge tile.
Conservation Area
A conversation area is a location of exceptional architecture, outstanding natural beauty or historic interest.
If your property falls within a conservation area, you are required to take several points into consideration. If your intended roof or roofs face a public highway, you will need to reconsider. Areas of your property that are visible from a public highway or footpath are not permitted for panel installation. Instead, you would need to review the feasibility of installing PV modules on the back of your property.
Properties that are within the same grounds as a listed building are classed as falling under a conservation area.
Flats
If you own a block of flats or a maisonette, you will need to make a planning application to the local authority.
If you own a flat/apartment that is within a block, you do not necessarily own the roof space, even if you are on the top floor. It is best to check your properties deeds or your lease agreement, however in most cases, you will not own the roof section. You may have access to the roof, however an application may be required to allow installation. In some cases, this can be an easy process, on the other hand, it can be tedious and have further fees attached.
