Screening, light and neighbouring windows
A practical guide to adding a tall garden screen near a neighbour's window while respecting their light and UK planning rules.
A tall screen can improve privacy in your garden, but it can also block daylight from a neighbour's window. Before you build, you need to consider two separate issues: planning permission and the common law right to light. The Planning Portal explains that permitted development rights for fences and walls limit height to two metres, and higher structures may need permission. This article helps you decide what to check first, how to assess light loss, and when to talk to your neighbour or your local council.
What does the law say about light and tall structures?
The law on light is split between planning rules and private rights. Planning rules set out what you can build without permission. The Planning Portal provides guidance on common projects and permitted development. If your screen exceeds two metres, you may need planning permission. Separately, a neighbour may have a right to light if their window has received daylight for many years. You can ask your local council's planning department for advice. If a dispute arises, you may need to consult a solicitor or a specialist surveyor.
How do I check if my screen needs planning permission?
The main limit is height. The Planning Portal notes that fences, walls and gates are usually permitted development if they are no more than two metres high. If your screen is taller than two metres, or if it is in a conservation area or near a highway, you should check with your local planning authority before building. The Planning Portal's 'Do you need permission?' tool can help you find out. You can also search for your council's contact details using their 'Find your council' service. Always keep a record of any advice you receive.
What is a right to light and when does it apply?
A right to light is a legal right that can prevent a neighbour from blocking your windows with a structure. It is not covered by the Planning Portal. If a neighbour's window has enjoyed unobstructed daylight for a long period, they may have a right to light. This is a complex area of law. The Ministry of Housing, Communities and Local Government (MHCLG) oversees the planning system, but individual rights are enforced through the courts. If you are unsure, you should seek legal advice. Do not rely on planning permission alone as a defence against a right to light claim.
How can I reduce the impact on a neighbour's window?
Start by measuring the distance between your proposed screen and the neighbour's window. The further away the screen, the less light it will block. You can also lower the height or make the screen partially transparent. Consider using a trellis or slatted design instead of a solid panel. This allows more light to pass through while still providing privacy. You should also think about the orientation: a screen directly south of a window will block the most light. If possible, position the screen so it does not sit directly in front of the window.
What should I discuss with my neighbour before building?
Talk to your neighbour early. Explain what you want to build, why you need it, and ask if they have any concerns. They may not realise you are planning a screen, and a friendly conversation can prevent a dispute later. If they are worried about light, you can suggest a lower height or a different material. You can also agree to move the screen slightly. The MHCLG encourages communities to work together, and local councils often prefer neighbours to resolve issues informally. If you cannot agree, you may need to apply for planning permission, and your neighbour will be able to comment on your application.
When should I get professional advice?
Get professional advice if you are unsure about planning rules, if your neighbour objects, or if you receive a legal letter. A planning consultant can help with applications. A solicitor can advise on rights to light. A surveyor can measure light levels. The Planning Portal offers a paid planning advice service, but it does not cover private legal rights. For legal matters, you should consult a solicitor. For planning matters, your local council's planning department is the first point of contact.
What are the practical alternatives to a tall solid screen?
If a tall solid screen is not possible, consider these options: a lower fence, a hedge, a trellis with climbing plants, or a combination of these. A hedge can provide privacy and is often more acceptable to neighbours, but it needs maintenance. Trellis lets light through and can support plants. You can also use outdoor blinds or movable screens that are only up when you need privacy. The table below compares common options.
| Option | Light impact | Privacy | Planning notes |
|---|---|---|---|
| Solid fence or screen | Blocks most light | High | Usually permitted up to 2m |
| Trellis with climbers | Lets light through | Medium | Often permitted |
| Hedge | Varies by species | Medium to high | May need maintenance |
| Slatted screen | Partial light | Medium | Check local rules |
| Movable screen | Can be adjusted | Variable | May not need permission |
Before choosing, check the Planning Portal for guidance on fences and walls. For more on materials, see our guides on fence panel material comparison and trellis and climbing screens. If you are concerned about wind, read wind and exposure considerations.
What steps should I take before ordering materials?
Follow this checklist:
- Measure the proposed height and distance from any neighbouring windows.
- Check the Planning Portal's guidance on permitted development for fences and walls.
- If your screen is over two metres, contact your local planning authority.
- Talk to your neighbour about your plans and listen to their concerns.
- Consider alternatives such as lower height, trellis, or a hedge.
- If you proceed, keep records of your research and any communication.
- If a dispute arises, seek legal advice promptly.
Remember that planning permission does not automatically override a neighbour's right to light. You may need to address both issues separately. For more on boundaries, see boundary ownership and property deeds.
Conclusion
Adding a tall screen near a neighbour's window requires careful thought. Check planning rules first, then consider the potential impact on light. Talk to your neighbour early and be open to compromise. If you are unsure, consult the Planning Portal or your local council. For legal questions about rights to light, speak to a solicitor. By taking these steps, you can enjoy your garden while respecting your neighbour's light.
