PV Panels Planning Permission

This guide covers England as of October 2026. It is general information, not legal advice. Always confirm the rules with your local planning authority.

Do Solar Panels Need Planning Permission?

In most cases in England, no. Do you need planning permission for solar panels on a house? Usually not, because most roof and garden systems count as permitted development. However, limits and exceptions apply. Therefore, you should check your property before you book an installer.

Planning permission and solar panels connect through one idea: permitted development. These rules grant automatic consent when a project stays within set limits. They sit in Part 14 of the General Permitted Development Order. In addition, the government published the 2026 changes at the end of July. As a result, PV panels planning permission now depends on your property type and panel position.

What Is Permitted Development?

Permitted development is a national grant of planning consent. It lets you carry out certain work without applying to your council. You can read a general overview on the Wikipedia page on permitted development rights. Even so, councils can remove these rights in some areas through an Article 4 direction. Consequently, a quick call to your council can save you time and money.

What Changed on 27 August 2026 for PV Panels Planning Permission?

England updated its permitted development solar panels rules on 27 August 2026. First, the government split the rules for houses and blocks of flats. As a result, houses gained room for larger installations in more places. Second, the update confirms that plug-in solar can qualify. However, it blocks plug-in panels on wooden structures and timber cladding. This limit reduces fire risk.

A 12-month transitional period also applies. Until late August 2027, you can follow either the old rules or the new ones. Therefore, a project that fitted the old limits still stands. Meanwhile, the new rules give houses extra flexibility. The Planning Portal solar panels guidance shows both versions side by side.

Many websites still show the pre-2026 limits. Consequently, check the publication date before you trust any guide. In short, PV panels planning permission advice from early 2026 may already be out of date.

PV Panels Planning Permission for Roof-Mounted Systems

Roof systems remain the easiest case. Most houses in England can fit panels without applying to the council. Nevertheless, every roof must meet a few clear limits. The rules below apply to houses in England.

Pitched Roofs

On a pitched roof, panels must stay below the highest part of the roof. The chimney does not count. In addition, panels must project no more than 200mm from the roof slope. Most standard roof-mounted kits meet this limit. Therefore, a typical tiled roof rarely needs a planning application.

Flat Roofs

Flat roofs need a different check. The highest part of the solar equipment can sit no more than 600mm above the highest part of the roof. Again, the chimney does not count. Furthermore, a flat roof on designated land needs prior approval first. Designated land includes conservation areas, national parks, the Broads, Areas of Outstanding Natural Beauty and World Heritage Sites. Tilted frames on flat roofs therefore need careful height planning.

Walls, Balconies and Plug-In Solar

Houses can now mount panels on walls, balconies and roof enclosures. The panels can project up to 0.4 metres from the wall. However, the limit drops to 0.2 metres where the wall abuts a highway. In a conservation area or World Heritage Site, panels cannot go on a wall, balcony or enclosure that fronts a highway.

Plug-in solar connects to your home wiring through a standard socket. It now fits within these rules. However, you cannot mount it on a wooden wall, balcony or enclosure, or on any timber-clad exterior.

Rules That Apply to Every Roof

Two general conditions apply to all installations. First, you should site the equipment to limit its effect on the building’s appearance and the local area. Second, you should remove the equipment as soon as reasonably practicable once you no longer need it. In addition, leaseholders may need permission from the landlord or management company.

Can I Put Solar Panels in My Garden? UK Rules Explained

So, can I put solar panels in my garden UK homeowners often ask? Yes, you can. Ground-mounted frames work well when your roof faces the wrong way or carries too much shade. However, a garden array is not automatically free of planning rules. Stand-alone solar has its own limits, and these tighten near boundaries and roads.

Size and Height Limits for Garden Arrays

For a house in England, the array can cover no more than nine square metres. Height limits then depend on position. The lowest applicable limit applies:

• 1 metre, when the array sits within 5 metres of the boundary and forward of the front of the house.
• 2 metres, when the array sits within 5 metres of the boundary.
• 2 metres, in a conservation area and nearer the highway than the house.
• 4 metres in every other case.

Nine square metres holds roughly four or five modern panels. Therefore, this route suits a small garden system, not a large array. A bigger ground-mounted system usually needs a planning application.

Boundaries, Roads and Special Land

Position matters as much as size. In a conservation area, an array closer to the highway than the nearest part of the house needs prior approval. The same applies on designated land within 5 metres of the curtilage boundary. In a World Heritage Site, the array must stay at least 5 metres from the boundary. It also cannot sit nearer the highway than the house.

You cannot use this route inside the grounds of a listed building or a scheduled monument. In those cases, you need to apply for planning permission. Plug-in garden solar also cannot attach to a wooden fence, gate or wall.

Old Rules or New Rules?

The old stand-alone rules allowed a 4 metre height and a minimum 5 metre boundary distance. They also capped the array at nine square metres, or three metres by three metres. During the transition, you can still use them. For many gardens, the new rules offer more flexibility. For others, the old distance rule fits better. Therefore, ask your installer which route suits your plot

Permitted development covers most homes. Nevertheless, some projects still need a formal application. Here are the main cases.

Listed Buildings and Scheduled Monuments

Permitted development does not cover panels on a listed building or in its grounds. Instead, you need planning permission. A listed building usually also needs listed building consent. Councils often prefer panels on a modern outbuilding or on the ground.

Article 4 Directions and Removed Rights

A council can remove permitted development rights in a specific area. In that case, you need a full application even for a standard roof array. Therefore, check your council’s Article 4 map before you order equipment. Finding a direction after installation is an expensive way to learn the rule.

Projects Above the Limits

Projects that exceed the limits also need permission. For example, panels that project beyond 200mm from a pitched roof fall outside the rules. Likewise, a garden array above nine square metres needs an application. In such cases, a planning consultant can help you build a strong case.

Flats and Leasehold Homes

Blocks of flats follow separate permitted development rules. Most leasehold buildings also need landlord or freeholder consent, whatever the planning position. Consequently, speak to your management company early. Shared roofs often need a joint decision from all residents.

England, Scotland, Wales and Northern Ireland

This guide explains the rules for England. Scotland, Wales and Northern Ireland each run their own planning systems. Their permitted development limits differ in detail. For example, flat roof, system size and conservation area rules vary between nations. Therefore, do not assume that English limits apply elsewhere.

If you live outside England, check your national planning guidance and your local council. In addition, ask your installer to confirm the rules for your postcode. PV panels planning permission always depends on where the property sits.

Commercial and Larger Systems

Businesses also benefit from permitted development. Rooftop solar on warehouses, factories and community buildings can qualify, subject to conditions. In December 2023, the government removed the 1 megawatt cap on non-domestic rooftop solar. As a result, many large commercial roofs can proceed without a full application. The Planning Portal non-domestic solar guidance lists the current conditions.

Ground-mounted solar farms are different. These schemes need planning permission from the local planning authority. They also face environmental, landscape and grid questions. For help with larger roofs and sites, read about commercial solar system design in the UK. In addition, early grid checks protect your budget on any commercial project.

Planning Rules at a Glance for PV Panels Planning Permission

This table summarises PV panels planning permission for common cases in England. Use it as a quick check, and then confirm the details with your council.

Planning Is Only One Step for PV Panels Planning Permission

Many owners stop at planning. However, a solar system needs several other approvals. Therefore, treat PV panels planning permission as one part of a longer process. Planning permission and solar panels also sit alongside separate technical and electrical checks.

Building Regulations and Electrical Safety

Planning rules cover appearance and position. Building regulations cover structural safety, fire and electrical work. Consequently, a project can satisfy planning and still fail a safety check. For example, a roof must carry the extra load, and the wiring must follow BS 7671. Your installer should confirm both points.

Grid Connection and the DNO

Your distribution network operator (DNO) owns the local electricity network. Therefore, you must tell the DNO about your system. Smaller systems, up to 16 amps per phase, usually follow the G98 notification route. Larger systems need G99 approval before connection. A battery or second inverter can change the route, so check the total rating. You can learn how a DNO application works in our guide.

Drawings That Support Every Approval

Good drawings speed up every step. For example, a roof layout shows the council where panels will sit. Likewise, a single-line diagram shows the DNO how power flows. Our guide to clear solar system drawings explains what each sheet should show. In addition, solar permit design that supports your application keeps drawings and forms consistent.

Standards differ between countries, so check the local rules before you start. Our comparison of solar plan set requirements across the UK, USA and Canada shows the differences. Meanwhile, installers should confirm MCS certification, because it matters for Smart Export Guarantee payments.

Your Pre-Installation Checklist for PV Panels Planning Permission

Follow these steps to avoid delays. Each one takes minutes, yet each can save weeks.

Step 1: Check Your Property Type

Confirm whether you own a house, a flat or a listed building. Then check if the property sits in a conservation area or on designated land. This single check answers most PV panels planning permission questions.

Step 2: Check for Article 4 Directions

Look at your council’s online map. Alternatively, call the planning team. Ask whether any direction removes solar permitted development rights at your address.

Step 3: Measure the Proposed Array

Record the roof pitch, panel projection and total area. For garden systems, also measure distances to boundaries and roads. As a result, you can compare your plan with each limit.

Step 4: Plan the Grid Connection Early

Choose the G98 or G99 route before you order equipment. Busy networks may request export limits. Therefore, early planning protects your timeline and budget.

Step 5: Consider a Certificate of Lawfulness

Some owners apply for a lawful development certificate for extra certainty. This certificate confirms that your project meets the rules. It can also help when you sell the property. Ask your council about the process and fee.

Questions to Ask Your Installer

Ask whether the installer holds MCS certification. Then ask who prepares the DNO paperwork. Also ask how the installer checks planning limits. Clear answers show a professional team.

FAQs about PV Panels Planning Permission

Do solar panels need planning permission?

Usually not. Most roof and small garden systems in England count as permitted development. Listed buildings and some protected areas need extra steps.

Can I put solar panels in my garden UK?

Yes. In England, a garden array can cover up to nine square metres. Height limits depend on how close the array sits to the boundary and road.

Do solar panels on a flat roof need planning permission?

Usually not. The panels can rise 600mm above the roof. However, flat roofs on designated land need prior approval first.

Do I need planning permission for solar panels in a conservation area?

Often not, but limits are tighter. Panels cannot go on walls facing a highway. Garden arrays nearer the road than the house need prior approval.

Do I still need DNO approval if I skip planning permission?

Yes. Planning and grid approval are separate. You must notify or apply to your DNO under G98 or G99 before connection.
