Do You Need Planning Permission for Solar Panels in the UK?

If you’re asking yourself, “Do you need planning permission for solar panels?”, you’re not alone. In most situations, you do not need planning permission for solar panels.

However, there are specific scenarios where planning permission might be required. Solar panels are an excellent way to lower your energy bills, reduce your carbon footprint and invest in a sustainable future.  

In this guide, we answer the question: do you need planning permission for solar panels? We’ll explain the reasons behind the rules and show how E-Verve Energy provides a seamless process tailored to your needs.

When Planning Permission is not Required (Permitted Development Explained)

Under UK legislation, the question “do you need planning permission for solar panels?” often has a simple answer. Residential properties generally qualify under “permitted development,” meaning you don’t need planning permission in most situations. This regulation encourages the adoption of renewable energy and makes it simpler for homeowners to benefit from solar power.

Here’s when you usually do NOT need planning permission for solar panels:

  • Standard solar panel installations on the roof or walls of your house or outbuilding.
  • Standard solar installations within your property’s boundaries, if they are not facing a public highway.
  • Complying with these rules:
    • Solar panels must not protrude more than 200mm beyond the roof or wall surface.
    • No panels should sit above the highest part of your roof (not including chimneys).

By following these guidelines, most homeowners will find that they do not need planning permission for solar panels, making installation even easier and quicker.

When Planning Permission is Required

Despite permitted development rights, you may still be wondering if you need planning permission for solar panels in exceptional cases. You will typically need planning permission in the following scenarios:

On a Listed Building

For listed buildings, planning permission is often necessary to protect the property’s historical and architectural significance. Installing solar panels could change the character of a listed building, so authorities carefully assess these applications.

In Conservation Areas, National Parks or World Heritage Sites

If your home is in a conservation area, a national park, or a World Heritage Site. You may need planning permission for solar panels. If your installation is visible from a public road or space you may need planning permission. This is to help preserve the location’s unique visual character.

If the installation is oversized

Larger solar panel arrays, such as extensive ground-mounted systems or setups that significantly alter a building’s exterior. These will likely require planning permission. If you plan to cover a large area or transform your property’s appearance, it’s best to check if planning permission is your exact circumstances.

On a Flat Roof or for Freestanding Arrays

Freestanding solar panel arrays or those installed on a flat roof may need planning permission. This will be dependent on their size, height, and overall appearance. These setups differ from typical roof-mounted solar panels and are subject to specific regulations.

Do You Need Planning Permission for Solar Panels

Why is Planning Permission for Solar Panels sometimes required?

The need for planning permission in these scenarios arises from practical concerns. Such as maintaining the balance between environmental progress and heritage or community aesthetics. Here are some key reasons:

  • Preserving Heritage: Historic and culturally important structures must be protected. So planning rules exist to ensure solar panels do not detract from these buildings.
  • Maintaining Community Aesthetics: Solar panels visible from public roads or common areas can alter the neighbourhood or rural landscape. Planning permissions help manage this.
  • Ensuring Safety: Larger installations undergo additional safety checks, especially for freestanding or flat-roof systems.

These regulations ensure that when you do need planning permission for solar panels, it serves to protect broader community interests without creating unnecessary obstacles.

Planning Permission for Solar Panels: Not a Barrier

Needing planning permission should not discourage you from pursuing solar energy. UK planning policy encourages responsible renewable energy adoption while protecting historical and community features. With expert guidance, determining if you need planning permission is straightforward and stress-free.

If you’re considering installing ground mounted solar panels to cut your energy bills and reduce your carbon footprint, it’s essential to understand the specific planning permission rules in the UK. The question is: Do you need planning permission for ground mounted solar panels?

Most UK homeowners don’t need planning permission for ground-mounted solar panels. However, you must follow important regulations and exceptions to stay compliant with local council rules.

Understanding Permitted Development Rights

In England and Wales, most ground mounted solar panel installations on domestic properties fall under “Permitted Development.” This means that, as long as you meet certain criteria for ground mounted systems, you typically do not need to apply for planning permission from your local authority. This simplifies the process and helps homeowners adopt renewable energy more easily.

However, Permitted Development rights for ground mounted solar panels come with strict conditions. To install ground mounted solar panels without planning permission, your system must meet requirements regarding height, positioning, and appearance. If your ground mounted installation does not satisfy these criteria, you will need to apply for planning permission before moving forward.

Requirements for Ground Mounted Solar Panels

For standard ground mounted solar panels on a residential property, you generally do not need planning permission provided you adhere to the following limits and conditions:

1. Height Limits

For ground mounted solar panels, the installation must not exceed 4 metres in height above ground level. This restriction ensures the array remains unobtrusive within your property and does not dominate the surrounding landscape.

2. Proximity to Roof Edge

Position ground-mounted solar panels and their supporting framework at least 5 meters away from your property boundary. This placement helps reduce any potential visual impact on neighbours and maintains compliance with planning regulations related to privacy and landscape effects.

3. Conservation Areas and World Heritage Sites

If you live in a Conservation Area or a World Heritage Site, restrictions are significantly stricter for ground mounted solar panels. You should not install ground mounted panels within the grounds of a property that fronts a highway (which includes public roads, footpaths, and bridleways) unless you have obtained planning permission. You will likely need to seek planning permission from your local authority if your proposed array is positioned to be visible from a highway in these designated areas.

4. Listed Buildings

If your property is a Listed Building, the rules are much tighter. You will almost certainly need Listed Building Consent for any external additions, including ground mounted solar panels. In many cases, you will also need full planning permission. Installing panels on a listed building without consent is a criminal offence, so always check with your local conservation officer first.

5. Visual Impact

Site panels and their frameworks “so far as is practicable” to minimize their impact on the landscape and the area’s amenity. Arrange them neatly and align them uniformly to avoid a cluttered or intrusive appearance.

6. Removing Disused Panels

There is a condition that if the ground mounted solar panels are no longer needed for microgeneration, they should be removed as soon as reasonably practicable.

When Do You Need Planning Permission?

So, do you need planning permission for ground mounted solar panels? You will need planning permission if:

  • You live in a flat or maisonette: While Permitted Development often covers houses, rights for flats can be different or restricted. Always check your leasehold agreement and local council policies.
  • Article 4 Directions apply: Some local authorities remove Permitted Development rights in certain areas (often conservation areas) using an “Article 4 Direction.” If this applies to your area, you need planning permission for almost any external changes.
  • Your panels exceed height or edge limits: If the flat roof installation is less than 200mm from the edge or rises more than 1 metre above the roofline, you need permission.
  • You are mounting them as a standalone ground structure: Standalone solar arrays have separate rules, usually a 4-metre height maximum.
  • Commercial properties: The rules for non-domestic buildings may differ, though allowed rights typically apply up to a specific system capacity.

The “Prior Approval” Process

For ground mounted solar panels on residential properties, the “Prior Approval” process typically does not apply. This process is mainly relevant for larger, non-domestic ground-mounted installations or community energy projects where the council assesses factors like visual impact and glare. Standard residential ground mounted solar panel systems almost never require prior approval, as long as all permitted development requirements are satisfied.

Steps to Take Before Installation

Even if you are confident you don’t need planning permission for ground mounted solar panels, it is wise to take these precautionary steps:

  1. Contact Your Local Planning Authority (LPA): A quick check with your council can save you headaches and expenses. Ask if Article 4 Directions apply to your property.
  2. Apply for a Lawful Development Certificate (LDC): For peace of mind, consider an LDC. This legal document from the council proves your installation was compliant at the time and is valuable when selling your home.
  3. Check Your Deeds: Some properties have restrictive covenants that override planning allowances.
  4. Consult Your Installer: MCS-certified installers are familiar with these regulations and can usually assess whether your design meets permitted development rules.

Building Regulations

It is crucial to distinguish between planning permission and building regulations for ground mounted solar panels. Even if your installation does not require planning permission, you must always comply with Building Regulations.

This ensures that the ground and foundations can safely support the additional weight of the panels and mounting system, that electrical installations are carried out to the highest safety standards, and that the installation does not compromise drainage or surrounding structures. Reputable installers—often members of NICEIC or NAPIT—can self-certify their work and issue a compliance certificate.

Conclusion

For most UK homeowners, you do not need planning permission to install ground mounted solar panels, provided your installation strictly complies with permitted development rules. By adhering to the height and boundary distance requirements—and paying close attention to regulations for conservation areas and listed buildings—you can usually install ground mounted panels without unnecessary hassle.

However, always keep the following in mind:

  • Be extra cautious in Conservation Areas and always seek consent for installations near Listed Buildings.
  • Do not install ground mounted panels higher than 4 metres above ground level.
  • Position panels at least 5 metres from the boundary of your property.

If you’re thinking about installing wall-mounted solar panels to cut your energy bills and reduce your carbon footprint, it’s important to understand the planning permission rules specific to these systems in the UK. The question is: Do you need planning permission for wall-mounted solar panels?

Most UK homeowners don’t need planning permission for wall-mounted solar panels. However, you must follow important rules and exceptions specific to wall-mounted installations to comply with local council regulations.

Understanding Permitted Development Rights

In England and Wales, most wall-mounted solar panel installations on domestic properties fall under “Permitted Development.” This means that, as long as you meet specific criteria for wall-mounted systems, you typically do not need to apply for planning permission from your local authority. This is excellent news for homeowners looking to install wall-mounted solar panels, as it simplifies the process and removes much of the administrative burden.

However, Permitted Development rights for wall-mounted solar panels are subject to strict conditions. To install wall-mounted solar panels without planning permission, your system must meet specific requirements regarding how far panels can project from the wall, their height relative to the roof, and their impact on the building’s appearance. If your wall-mounted installation does not satisfy these criteria, you will need to apply for planning permission before going ahead.

Requirements for Wall-Mounted Solar Panels

For standard wall-mounted solar panels on a house or a block of flats, you generally do not need planning permission provided you adhere to the following limits and conditions:

1. Protrusion Limits

The panels must not protrude more than 200mm (about 8 inches) from the external surface of the wall or roof. This rule ensures the panels sit relatively flush against the building rather than sticking out obtrusively.

2. Height Restrictions

The highest part of the solar panel must not be higher than the highest part of the roof (excluding the chimney). For wall-mounted systems, this usually means you can’t install them in a way that extends above the eaves or roofline.

3. Conservation Areas and World Heritage Sites

If you live in a Conservation Area or a World Heritage Site, the rules are stricter. You generally cannot install panels on a wall that fronts a highway. “Highway” includes public roads, footpaths, and bridleways. If your wall faces a public road in these protected zones, you will likely need planning permission.

4. Listed Buildings

If your home is a Listed Building, the rules are much tighter. You will almost certainly need Listed Building Consent for any internal or external alterations, including solar panels. In many cases, you will also need full planning permission. Installing panels on a listed building without consent is a criminal offense, so always check with your local conservation officer first.

5. Visual Impact

While subjective, the regulations state that panels must be sited “so far as is practicable” to minimise the effect on the external appearance of the building and the amenity of the area. This usually means keeping them neat, aligned, and not placing them in erratic patterns.

6. Removing Disused Panels

The regulations also include a condition that if the solar panels are no longer needed for microgeneration, they should be removed as soon as reasonably practicable.

When Do You Need Planning Permission?

So, do you need planning permission for wall-mounted solar panels? You will need planning permission if:

  • You live in a flat or maisonette: While Permitted Development often covers houses, rights for flats can be different or restricted. Always check your leasehold agreement and local council rules.
  • Article 4 Directions apply: Some local authorities remove Permitted Development rights in specific areas (often conservation areas) using an “Article 4 Direction.” If this applies to your street, you need planning permission for almost any external change.
  • Your panels are too big or project too far: If you want a mounting system that sticks out more than 200mm, you need permission.
  • You are mounting them on a ground structure: Standalone solar installations in your garden have different rules (e.g., they can’t be more than 4 meters high).
  • Commercial properties: The rules for non-domestic buildings are slightly different, though permitted development often still applies up to a certain capacity (usually 1MW).

The “Prior Approval” Process

For wall-mounted solar panels on residential properties, the “Prior Approval” process is generally not relevant. This process is primarily intended for larger, non-domestic installations or specific community energy projects where the council needs to consider factors like design and glare. Standard residential wall-mounted solar panels almost never require prior approval, provided all permitted development conditions are met.

Steps to Take Before Installation

Even if you are confident you don’t need planning permission for wall-mounted solar panels, it is wise to take a few precautionary steps specific to these installations.

Contact Your Local Planning Authority (LPA)

A quick email or phone call can save you thousands of pounds in fines or removal costs later. Ask them if there are any Article 4 Directions in place for your address.

Apply for a Lawful Development Certificate (LDC)

If you want peace of mind, you can apply for an LDC. This is a legal document from your council confirming that your work was lawful at the time it was carried out. This is incredibly useful if you ever sell your house, as solicitors will ask for proof that the panels comply with regulations.

Check Your Deeds

Sometimes, restrictive covenants on property deeds prevent external alterations, regardless of planning laws.

Consult Your Installer

Reputable MCS-certified installers deal with these regulations daily. They can usually advise you on whether your specific design complies with Permitted Development rules.

Building Regulations

It is vital to distinguish between planning permission and building regulations for wall-mounted solar panels. Even if your wall-mounted installation is exempt from planning permission, you must still comply with Building Regulations.

This ensures the wall you choose for mounting can safely support the weight and stress of the solar panels, that all electrical work meets required safety standards, and that the building remains weatherproof after installation. For wall-mounted solar panels, certified professionals—often registered with schemes like NICEIC or NAPIT—can self-certify their work and provide you with the necessary compliance certificate to confirm your installation meets Building Regulations.

Conclusion

For most UK homeowners, you do not need planning permission to install wall-mounted solar panels, provided your installation strictly follows the permitted development rules. By complying with limits on protrusion, height, and visual impact—and remaining especially cautious in conservation areas or with listed buildings—you can typically add wall-mounted panels without red tape.
