Everything You Need to Know About Solar Panel Planning Permission in Surrey

15th Oct 2025

Thinking about installing solar panels on your home in Surrey? 

One of the first questions many Surrey homeowners ask is whether planning permission is required. The good news is that in most cases, solar panels fall under what’s known as permitted development. That means you don’t usually need planning permission to get started.

However, there are some important rules, regulations, and steps you’ll need to be aware of to make sure your installation is safe, compliant, and future-proof. At Sheerwater Solar, we’re here to make the process simple and stress-free, so let’s break down everything you need to know.

Building Regulations and Planning Permission

In the UK, solar panel installations are subject to building regulations and planning restrictions. For most standard homes, planning permission is not required, but there are some exceptions.

  • Listed buildings: If your home is listed, planning permission will almost certainly be required.

  • Conservation areas and Areas of Outstanding Natural Beauty: Additional rules often apply, so you will need to check with your local authority before proceeding.

  • Flat roofs: Updates to the rules in 2023 mean installations on flat roofs now have specific requirements you’ll need to follow.

Even when planning permission is not required, your solar panel system must still comply with building regulations. These cover structural stability, fire safety, electrical safety, and more.

Regulations That Apply

Installing solar panels isn’t just about securing planning permission. There are several regulations you need to comply with to ensure your system is safe and efficient. These include:

  • Building Regulations: Covering structural safety, fire resistance, and ventilation.
  • Electrical Safety Regulations: Ensuring earthing, insulation, and protection against overvoltage are in place.
  • Health and Safety Regulations: Covering safe working at height, proper equipment use, and ongoing maintenance.

Key Steps in the Process

To make sure your solar panel installation goes smoothly, there are some key steps you’ll need to follow:

  1. Notify the local building control authority

    Submit either a building notice or full plans approval before starting the work.

  2. Obtain structural calculations

    If panels are not being mounted on an existing roof, a qualified engineer or surveyor must confirm the structure can handle the load.

  3. Ensure adequate ventilation

    Panels generate heat, so ventilation is essential to prevent overheating.

  4. Plan for safe access and working at height

    Safety rails or equipment may be required to protect installers and maintenance teams.

  5. Meet electrical safety standards

    From cabling to switches, all electrical work must comply with strict UK regulations.

  6. Obtain a completion certificate

    Once installation is complete, a certificate from your local building control authority confirms compliance.

By following these steps, you’ll not only meet the legal requirements but also protect your investment for years to come.

Maintenance and Monitoring

One of the biggest benefits of solar panels is that they require very little maintenance. To keep your system working at its best:

  • Keep panels clean and free from debris, we advise you to clean your panels once or twice a year – our sister brand Sheerwater Clean can help you with this!

  • Carry out regular inspections – give us a call and we’d be happy to come out to you and check that your panels are performing at their best.

  • Consider adding panel-level monitoring or optimisers to track individual panel performance.

These simple steps help maximise energy generation and spot any issues early.

The Importance of the Completion Certificate

The final step in the process is obtaining your completion certificate. This document proves that your installation meets all the relevant building and electrical safety regulations.

It is more than just a formality. The certificate:

  • Confirms your system is safe and compliant.
  • Provides reassurance to future buyers if you ever sell your home.
  • Acts as a record of professional, high-standard installation.

Keeping this certificate safe is vital, as it shows your investment has been properly installed and approved.
