Losing natural light because of a neighbour’s extension, new building or overgrown hedge can be frustrating. It can make your home darker, affect your garden and reduce your enjoyment of your property.
However, the rules in Scotland are different from those in England and Wales. There is no general legal right to light in Scotland, meaning you cannot automatically stop your neighbour from building something simply because it blocks sunlight.
There are, though, important exceptions. Planning rules, property title conditions and specific laws covering high hedges may give you options if your neighbour’s actions affect the light entering your home.
Is There a Right to Light in Scotland?
Unlike England and Wales, Scotland does not have a general legal right to light. This means that having enjoyed natural light through a window for many years does not automatically give you the right to prevent your neighbour from blocking it.
In England and Wales, a right to light can sometimes be established after 20 years of uninterrupted enjoyment. This rule does not generally apply in Scotland.
However, there are exceptions. For example, section 9(1)(b) of the Tenements (Scotland) Act 2004 restricts owners and occupiers from doing anything reasonably likely to reduce natural light in another part of the same tenement building to a material extent.
Your property deeds may also contain title conditions that protect your access to light. If you live in a flat or tenement, it is worth checking these documents before deciding what action to take.
Can Your Neighbour Build Without Your Permission?
Your neighbour may be able to build an extension, garage, garden wall or other structure without asking for your permission. Whether they need planning permission depends on the type, size and location of the proposed work.
Some home improvements fall under permitted development rights. These allow certain projects to go ahead without a separate planning application, provided they meet specific requirements.
However, permitted development rights have limits. Scottish Government guidance states that certain small buildings cannot qualify under the relevant permitted development rules if they would obstruct light to another building.
This does not mean every extension that blocks light is automatically unlawful. The rules depend on the particular development and the permitted development category being used.
How Does Planning Permission Affect Your Rights?
If your neighbour needs planning permission, the council should consider relevant planning issues when assessing their application. These may include the effect on neighbouring properties, residential amenity and overshadowing.
You can check your council’s online planning register to see whether an application has been submitted or approved. If the application is still open for comments, you can submit an objection explaining how the proposed development would affect natural light in your home or garden.
Include practical details, such as which rooms would become darker, how much of the garden would be affected and whether the building would be unusually close to your windows.
Planning permission does not automatically remove every private legal right, and a planning objection does not guarantee refusal. Equally, permission does not necessarily mean every aspect of the building work complies with the law.
Scottish planning authorities recorded 5,384 planning enforcement cases in 2024/25, showing that concerns about unauthorised development and compliance are a real part of the planning system.
What Can You Do If Your Neighbour Blocks Your Light?
Start by speaking to your neighbour. They may be willing to reduce the height of a structure, alter an extension or trim vegetation to reduce the impact.
If building work has started, contact your local council’s planning department to check whether permission is required and whether the work complies with any approval or permitted development rules.
If a tall hedge is blocking light, the High Hedges (Scotland) Act 2013 may provide another option. You can apply to your local council for a High Hedge Notice if the hedge meets the legal requirements. The council will consider the circumstances before deciding whether action is justified.
You should also check your property title conditions and seek advice from a Scottish property solicitor if you believe your legal rights have been breached.
When Should You Seek Legal Advice?
If the loss of light is serious, keep photographs, dates and copies of relevant planning documents. A solicitor can assess whether property title conditions, tenement legislation or another legal remedy applies to your situation.
The key point is that Scotland does not offer a general right to light, but that does not mean your neighbour can do anything they like. Planning controls and other property laws may still protect you, depending on the circumstances.
