Aperture may sound like the name of a pop song, but the right of light is a tangible and complex mechanism in real estate.
What is the right to light?
A right to light is a form of legal easement that entitles the owner or occupier of a building to receive a reasonable amount of natural daylight through defined apertures, such as windows, skylights or glass doors. It is not simply a right to enjoy sunlight or a pleasant view; it is a right to sufficient natural illumination for the ordinary comfortable use and enjoyment of a room.
If a neighbouring development substantially interferes with that light, the affected owner may have a legal claim.
When does the right arise?
Most rights of light arise automatically through long use (a “prescriptive” right), rather than being written into a deed.
Under the Prescription Act 1832, if a window has received natural light over neighbouring land for at least 20 uninterrupted years, a legal right can arise.
Rights of light can also be created expressly in a deed, or sometimes implied when land is divided. However, in practice, long, uninterrupted use is the most common route.
It is important to note that planning permission does not override private rights of light. A building project may comply with planning law but still infringe a neighbour’s established right.
What counts as an infringement?
The test for infringement is whether the obstruction amounts to a nuisance and whether sufficient light remains after a defendant’s action and whether it is adequate for a claimant’s purpose (Colls v Home and Colonial Stores [1904]).
A minor loss of light is not enough. The law does not protect direct sunlight, views, privacy, or property value, it applies only to sufficient natural illumination. As confirmed in Beaumont Business Centres Ltd v Florala Properties Ltd, the court focuses on the practical impact on usability, even if the room was already dim. The central question is whether the space has become genuinely and substantially less usable because of the loss of light.
What remedies are available?
If a right of light has been or is going to be infringed, the affected owner is entitled to apply for an injunction (an order to stop or alter any offending work) against the developer or claim for damages. Damages are often calculated based on a percentage of the profit that the developer makes from the infringement. The court also has discretion to award damages in lieu of an injunction.
Practical advice for property owners
If you are planning a development:
- Check early whether neighbouring properties may have acquired rights of light;
- Do not assume planning permission protects you; and
- Take specialist advice before building close to neighbouring windows.
If you are concerned about loss of light:
- Act promptly; and
- Seek professional advice on whether the loss is legally significant.
How Tees can help
Rights of light can be powerful, but they are not absolute. The law tries to balance the interests of property owners with the realities of modern development.
