Do You Need Planning Permission For Solar Panels?

In short, no, you typically do not require planning permission for solar panels due to general permitted development rights. This regulation usually allows the addition of solar panels without formal permission, provided your installation adheres to certain conditions such as:

• On a flat roof, the solar equipment must not be 600mm higher than the highest part of the roof, excluding any chimneys.
• On a pitched roof, solar equipment is not higher than the highest part of the roof, excluding any chimneys.
• If you live within the grounds of a listed building, solar panels cannot be installed without necessary permissions.

You can check with your Local Planning Authority (LPA) to confirm that your specific circumstances do not require you to apply for planning permission. Also, if you want to be sure that you do not require planning permission, you can apply for a Lawful Development Certificate (LDC).

What Are General Permitted Development Rights? Permitted development rights, or PDRs, allow certain building works and changes to be carried out without needing planning permission. These rights are set out by the UK government.

When Do You Need Planning Permission?

While most residential properties benefit from permitted development rights, there are some exceptions where you will need to apply for planning permission:

1. Conservation Areas and World Heritage Sites: While it is possible to install solar panels, you'll still need to apply for planning permission. One common requirement is that solar is allowed as long as it is not visible from public highways.
2. Listed Buildings: Planning permission and listed building consent are mandatory for any solar panel installations on listed buildings to ensure the integrity of the building is preserved.
3. Article 4 Directions: Certain local authorities may remove some permitted development rights under Article 4 Directions. If your property falls under an Article 4 Direction, which often includes heritage assets and conservation zones, a planning application will be necessary.

As mentioned above, to ensure you’re abiding by laws, always check with your Local Planning Authority.

As of December 2023, solar panel installations on flat roofs have seen revised regulations that allow more flexibility compared to previous years therefore reducing the need for planning permission. The panels may now project up to 60 cm above the roof's ridgeline which is an adjustment from the previous 20cm limit.

The Application Process For Solar Panel Installation

Follow the below application process for solar panel installation, which includes steps on applying for planning permission:

1. Check Local Regulations: Before you proceed, verify with your local planning authority (LPA) about specific requirements that may affect your property, especially if it's listed or in a conservation area.
2. Consultation: Engage a certified solar panel installer who can provide detailed insights and assessments tailored to your property's needs. This professional can also help you understand how to comply with local building codes and planning requirements.
3. Submit the Planning Application: If required, submit a planning application to your LPA. This includes detailed plans and drawings of the proposed installation.
4. Wait for Decision: Once submitted, the typical decision period is about eight weeks. During this time, the LPA might consult with neighbours or other stakeholders and may visit your property to assess the project.
5. Address Any Concerns: If there are objections or additional requirements from the LPA, address these promptly with the assistance of your installer.
6. Approval and Installation: Once approved, you can proceed with the installation of your solar panels.

Factors That May Impact Planning Permission Grants

When seeking planning permission for solar panels, various factors influence whether your LPA grants or denies your application. Understanding these elements can prepare you better for a successful planning process:

• Size and Visibility of Solar Panels: Large or highly visible panels may be refused if they significantly change the neighbourhood or building's character.

• Impact on Surrounding Environment: The LPA will assess if your solar installation harms local wildlife or protected habitats, especially near sensitive ecological areas.

• Neighbouring Amenities and Rights of Light: The LPA may refuse permission if your panels block sunlight or negatively impact neighbours' enjoyment of their properties.

Once again it is important to note that most residential homes where solar panels are fitted to a roof or wall do not require planning permission.

Appealing The Decision If Rejected

If your LPA rejects your solar panel installation application, you can appeal if any of the following apply, as set out by the UK government:

• Your planning permission was denied for reasons you believe contradict the LPA development plan or planning policy.
• You received planning permission but with conditions you disagree with - you must explain why you find them unnecessary, unenforceable, vague, unreasonable, or irrelevant.
• The LPA has not issued a decision on your application, and 8 weeks have elapsed since they acknowledged receipt of it (or a different agreed-upon deadline has passed).

---

Required Documents And Fees

To ensure a smooth application process, you'll need to gather several key documents:

• Site Plan: This should show the location of your property and the proposed placement of the solar panels.
• Detailed Drawings: Include specifications of the panel types, dimensions, and installation method.
• Ownership Proof: Documents proving your ownership of the property.
• Application Form: Completed form specific to your LPA’s requirements.

The fees for applying for planning permission vary by location and scale of the project.Check with your local authority for precise figures.

Types Of Solar Panel Installations & Planning Permission

Understanding the different types of solar panel installations can help you decide which suits your property and needs best while staying compliant with local regulations.

---

Ground-Mounted [Standalone] Solar Panels

Ground-mounted solar panels offer an alternative if roof space is insufficient or unsuitable for rooftop installations. These panels are installed directly into the ground on your property and allow for optimal positioning toward the sun, potentially increasing their efficiency. These installations might exceed the size restrictions set under permitted development rights and could require planning permission, especially if the area covered is more than 9 square metres or if the installation height surpasses 4 metres.

---

Wall-Mounted Solar Panels

These panels are installed vertically on the exterior walls of buildings, making them ideal for structures with limited roof space or those seeking to optimise all available surfaces for energy production. In many cases, they do not require explicit planning permission as long as they meet certain criteria, such as not protruding significantly from the wall or ensuring the walls can support the weight of the solar panels.
