When starting to research solar panels, many homeowners ask:
“Do I need planning permission to install solar panels in the UK?”
In most cases, you do not need planning permission. Solar panel installations on residential properties are usually covered by Permitted Development Rights. However, there are important exceptions and specific rules that must be followed.
This guide explains everything South East homeowners need to know.
Are Solar Panels Classed as Permitted Development?
For most homes in England, Scotland and Wales, solar panels fall under Permitted Development (PD), meaning planning permission is not required provided certain conditions are met.
Your installation must:
- Not protrude more than 200mm from the roof slope or wall surface
- Not be installed above the highest part of the roof (excluding the chimney)
- Be positioned to minimise visual impact on the building and surrounding area
- Be removed when no longer in use
If these criteria are satisfied, you can typically proceed without submitting a planning application. This applies to standard domestic rooftop solar PV systems.
When Is Planning Permission Required?
Planning permission may be required it:
You Live in a Listed Building
If your property is listed, you will almost certainly need Listed Building Consent, even if the panels are on a rear roof slope.
You Live in a Conservation Area
Solar panels are usually allowed, but restrictions apply. Panels must not be installed facing a visible public highway. Additional scrutiny may apply depending on the local authority.
You Live in an Area of Outstanding Natural Beauty (AONB) or National Park
Installations my still be allowed under permitted development, but visual impact is more strictly assessed.
Flat Roof or Ground Mounted Systems
Ground mounted systems must not exceed 9m², be no taller than 4 metres and be at least 5 metres from the property boundary. Larger systems typically require planning permission. Flat roof systems need to be below the highest point of the roof (excluding the chimney), so extension flat roofs usually don’t require planning permission but if your main roof is flat, planning permission may be required.
Do I Need Building Regulations Approval?
Even if planning permission is not required, Building Regulations approval is mandatory. Solar panels systems must comply with:
- Structural safety (roof load bearing capacity)
- Electrical safety standards (Part P)
- Fire safety compliance
A professional installer will handle certification and notify Building Control.
What About Solar Panels on Commercial Buildings?
Commercial solar installations follow similar permitted development rules but often require:
- Prior approval from the local planning authority
- Additional structural reports
- Grid connection approval
Each case depends on system size and property classification.
Do I Need Permission for Solar Batteries?
Battery storage systems usually do not require planning permission when installed internally (e.g. garage or utility room). External battery cabinets may require permission depending on size, location and visibility.
Solar Panels and UK Planning Law – Key Takeaways
- Most South East homes do not require planning permission
- Listed buildings almost always require Listed Building Consent
- Conservation areas may have additional restrictions
- Building Regulations approval is always required
- Ground mounted systems have size limits
Why Professional Advice Matters
Planning regulations can vary slightly between local authorities. Working with an experienced local installer ensures compliance with permitted development rules. You also guarantee you receive the correct documentation, MCS certification and proper Building Regulations sign off. At SolarTherm UK, we guide homeowners through every step – from eligibility checks to installation and certification.
Conclusion
For most UK homeowners, solar panels can be installed without planning permission. However, listed buildings, conservation areas and ground mounted systems may require additional approvals. Understanding the rules ensures a smooth installation process and avoids costly delays.
