Rights of Light – What Property Owners Need to Know?

If you’re planning building work that could affect a neighbour’s light, or worried a new development next door will block yours, you need to understand your right to light before things escalate.

A right of light is a private legal right, known as an easement, which can protect the amount of natural light passing through defined apertures, such as windows, skylights or rooflights. . It’s not a right to direct sunlight, or any view. The legal right allows for sufficient natural light for the ordinary use of the room.

Disputes around the right to light concern homeowners facing proposed new buildings, as well as property developers who are seeking to avoid easement disputes and delays.

How the Right to Light Protects Property Owners 

A right to light protects a property owner’s access to natural light through recognised apertures. The Prescription Act 1832 protects this right, which may be acquired after 20 years’ qualifying use, although rights can also arise in other ways.

Relevant apertures are usually windows but may also include skylights or roofs, and in some instances, fully or partially glazed doors, or other openings that admit natural light.

The right protects property owners’ enjoyment of their property and also its value. If a later building interferes with the natural light enjoyed by the property, the affected owner may have a claim.. It applies to residential properties and commercial buildings.

How Is a Right to Light Acquired?

You don’t acquire a right to light automatically. You can acquire it in one of three ways:

1. By express grant in a deed;
2. By implication, e.g. where the land is divided; or
3. By prescription, through long use

The most common way is prescription under the Prescription Act 1832.. Under this act, you can acquire a right to light if the property has enjoyed natural illumination through a window for at least 20 years under the provisions of the Prescription Act 1832. This enjoyment of natural illumination through a window or other opening must be without permission and without substantial interruption.

You can also acquire the right through a provision in a deed, or it can be implied when land is divided up.

The right is attached to the specific property which enjoys the illumination, so it passes to a new owner on a sale. If the property has changed hands during the twenty-year period, successive periods of ownership may count towards the qualifying period.

What Does a Right to Light Not Cover?

The right to light covers sufficient ‘natural’ illumination. It does not give a property owner a general right to the following;

• access to direct sunlight. 
• uninterrupted views from the property.
• the same amount of natural light before a neighbouring building was constructed, if the remaining light is still considered sufficient for the ordinary use of the room. Sometimes, the use of the room is pivotal, a kitchen requiring more natural light than a larder or store cupboard, and an artist’s studio requiring more than a kitchen. This strays into the debate about what is an ordinary use of a room.
• Future windows, extensions, or new buildings that have not enjoyed the relevant period of light.

Why Doesn’t Planning Permission Protect You From a Right to Light Claim?

Planning permission does not override private rights of light. Planning rules tend to focus on sunlight and daylight for amenity purposes in the public interest. This is distinct from a right to light which is a private legal right and does not depend on whether a development has planning consent.

Consequently, it’s possible to receive planning permission for a development and still create a structure which infringes the right to light. Developers should therefore assess rights of light early, ideally before finalising design, funding or construction timetables

What Happens If a Right to Light Is Infringed?

If your right to light is disrupted or infringed by a new building or an extension of an existing building, you may have a legal claim against your neighbours or the developer. 

If you have a legal claim, you may pursue an injunction to stop the development, or the court may award damages as compensation. The remedy will depend on the facts, including the extent of the interference, the conduct of the parties, and whether damages would be an adequate remedy

The courts tend not to focus on tangible light reduction but whether there’s a substantial interference with the use and enjoyment of the property. Typically, a solicitor and surveyor will use the Waldram method to establish any light infringement, measuring the new light levels against the baseline needed for ordinary use. It’s important that the correct measures are used to support a legal action.

Can a Right to Light Be Prevented or Removed?

If you’ve acquired a right to light through long use under the Prescription Act 1832, or it’s set out in an express grant, it is difficult to removeHowever, it may be released, varied or extinguished in some circumstances. 

If a right to light has not been acquired yet, an interruption in the flow of light may prevent the 20 year period from being completed.

If you’re a developer, you can protect future schemes by lodging a notice at HM Land Registry under section 2 of the Rights of Light Act 1959,.this is known as a Light Obstruction Notice and creates a notional obstruction, even though there is no physical obstruction on the land

What should you do if you are Worried about Rights of Light 

For property owners, keep records of the proposed works, take photographs, review any planning documents available online and seek advice before construction is completed. Delay can make it harder to protect your position.

For developers, assess rights to light at an early state by reviewing title documents or consider instructing an expert rights of light surveyor before building

Frequently Asked Questions

Can my neighbour block my sunlight?

Your neighbour can block your sunlight, but they cannot obstruct your right to natural illumination or natural light if you have enjoyed continuous use for at least twenty years. If your neighbour creates an obstruction but there is still sufficient natural light for you to enjoy ordinary use of that room, then it’s unlikely you have a claim against them.

How long does it take to acquire a right to light?

Unless a legal right is expressly contained in a grant, it takes twenty years of uninterrupted usage to acquire the right to light, protected by the Prescription Act 1832. The right is not specific to the property owner so can be established over a twenty-year period of continual occupancy even if the property has changed hands.

How do I know if my property has a right of light?

If light to a room has been present for twenty years without interruption, then you should be able to establish a legal right even though you may not have owned the property throughout the entire period. Remember, it’s a right to natural illumination, not sunlight. A specialist solicitor can advise you of your specific rights, particularly if you are worried about a proposed development.

What is a Light Obstruction Notice?

A Light Obstruction Notice is a device which allows developers to create a notional obstruction that doesn’t exist as a physical block. This will stop adjacent property owners from acquiring rights through the passage of time. The LON is registered on the title of the affected property at HM Land Registry.
