Does Commercial Solar Need Planning Permission? A Guide for Businesses
Commercial solar has become one of the fastest-growing ways for UK businesses to cut energy costs and reduce carbon emissions. But one of the most common questions we hear at Scott Electrical is:
“Do we need planning permission for commercial solar panels?”
The good news is that most commercial solar installations do NOT require planning permission — but there are some important exceptions. Here’s a clear guide to help you understand what applies to your building.
When Planning Permission Is NOT Required
Most rooftop commercial solar systems fall under Permitted Development Rights, meaning businesses can install panels without going through a full planning process.
Solar is generally permitted if:
- Panels do not protrude more than 200mm from the roof surface
- The highest part of the solar array is below the highest part of the roof
- The system is installed to minimise visual impact
- Your building is not listed or within a protected area
This covers the majority of commercial and industrial buildings throughout the UK.
When Planning Permission IS Required
You may require planning permission if:
1. Your building is listed
Any installation affecting the character of a listed building will need permission.
2. You’re in a conservation area, AONB, or national park
Special rules apply in protected zones.
3. Panels protrude more than 200mm
This includes raised frames or systems with unusual mounting structures.
4. You’re installing ground-mounted panels
Ground arrays normally require planning permission, especially if:
- over 9m²
- in view of public highways
- taller than 4m
- located on agricultural or development land
5. The roof structure requires reinforcement
If structural changes are needed, planning may apply.
