What Is a Right to Light Planning Objection?
A right to light planning objection may arise where a proposed development could significantly reduce the amount of natural light reaching a neighbouring property.
Extensions, new homes, taller buildings, conversions and other developments can alter the amount of daylight and sunlight available to nearby windows and rooms. Where the impact is significant, loss of light may be relevant to the planning assessment of the proposal.
However, it is important to distinguish between planning concerns about loss of daylight or sunlight and a legally enforceable right to light.
A right to light is generally a private legal right, usually taking the form of an easement allowing natural light to pass through a defined opening such as a window or skylight. Rights to light can arise in several ways, including express grant, implication or prescription.
The planning system and private rights to light therefore operate separately.
Can Loss of Light Be a Reason to Object to Planning Permission?
Yes. The potential effect of a development on the daylight and sunlight enjoyed by neighbouring properties can be considered as part of a planning application.
Government planning guidance states that local planning authorities should consider whether a proposed development would have an unreasonable impact on daylight and sunlight levels enjoyed by neighbouring occupiers. They may also consider whether future occupants of the proposed development would receive satisfactory levels of daylight and sunlight.
This means that a planning objection can raise concerns where, for example, a proposed building would:
- significantly reduce daylight entering neighbouring windows;
- create substantial overshadowing;
- reduce sunlight to important habitable rooms;
- affect the usability of gardens or external amenity spaces;
- introduce excessive height or massing close to an existing property;
- be positioned in a way that creates an unacceptable loss of natural light; or
- conflict with relevant local planning policies relating to daylight, sunlight, amenity or design.
The precise assessment will depend on the circumstances of the site and the planning policies applicable to the application.
Right to Light vs Loss of Light in Planning
One of the most important distinctions for property owners is that having a legal right to light is not the same as raising a planning objection about loss of light.
A private right to light can be an easement that restricts the extent to which a neighbouring landowner can interfere with the protected light. The Law Commission explains that such rights can potentially affect development even where planning permission has been granted because they operate separately from the planning system.
Planning authorities, meanwhile, assess the planning implications of a proposal. Government guidance specifically distinguishes private rights to light from planning considerations.
Consequently, receiving planning permission does not necessarily resolve a separate private rights-to-light issue.
Equally, simply stating that a property will lose some natural light does not automatically establish that a legally enforceable right to light has been infringed.
What Should a Right to Light Planning Objection Address?
A well-prepared planning objection should focus on material planning considerations, rather than simply stating that the proposed development will reduce the value or attractiveness of a property.
Depending on the application, relevant issues may include:
1. Daylight and Sunlight
Explain which windows, rooms or external areas could experience a material reduction in daylight or sunlight.
Where available, technical daylight and sunlight assessments can help demonstrate the potential impact.
2. Overshadowing
Consider the height, depth, orientation and position of the proposed development in relation to the neighbouring property.
A taller or closely positioned building may create additional overshadowing, particularly where the site relationship and orientation result in reduced access to sunlight.
3. Design and Massing
The scale and form of a proposed building can be relevant.
For example, an objection may consider whether reducing the height, depth or bulk of the development could reduce its impact on neighbouring properties while still allowing an appropriate form of development.
4. Residential Amenity
Loss of daylight or sunlight can affect the quality and usability of residential accommodation.
The planning objection should explain the practical consequences rather than simply stating that the development will cause a “loss of light”.
5. Local Planning Policy
The relevant local development plan and other applicable planning policies should be identified.
Planning authorities determine applications by considering the development plan alongside relevant material considerations.
How Is a Right to Light Established?
A legal right to light can arise in different ways.
HM Land Registry guidance explains that rights to light or air may arise through express grant, implication or prescription.
Prescriptive rights can be particularly important because a right to light may potentially arise following long use. Under the Prescription Act 1832, a claim can generally involve at least 20 years of continuous use, subject to the legal requirements and circumstances of the particular case.
This is one reason why property owners should not assume that the absence of an obvious document granting a right to light means that no such right exists.
What Evidence Can Support a Planning Objection?
Evidence can make a planning objection clearer and more persuasive.
Depending on the circumstances, this may include:
- photographs showing existing daylight conditions;
- photographs showing the relationship between the properties;
- architectural drawings;
- site plans and elevations;
- measurements of the proposed building;
- information about the orientation of the properties;
- daylight and sunlight assessments;
- relevant local planning policies;
- planning history;
- information about existing windows and affected rooms; and
- professional reports where specialist assessment is required.
A technical assessment may be particularly useful where the proposed development is substantial or the impact on neighbouring properties is disputed.
Does Planning Permission Override a Right to Light?
Not necessarily.
Planning permission and private rights to light are separate legal matters.
Government guidance confirms that private rights to light are not themselves part of the planning system, although they may affect the scope for development on neighbouring land.
This means a developer may obtain planning permission while still needing to address a separate private rights-to-light issue.
RICS also recognises rights of light as a specialist area with potential consequences including alterations to development proposals, compensation and, in some circumstances, injunctions affecting development.
Property owners should therefore consider both the planning position and any potential private legal rights where a proposed development could substantially affect natural light.
How Charrette Law Can Help
A right to light planning objection requires more than simply stating that a proposed development will make a property darker.
The objection should identify the relevant planning considerations, explain the likely impact and connect the concerns to applicable planning policies and evidence.
At Charrette Law, our planning and property expertise can assist with matters involving:
- planning objections concerning loss of daylight and sunlight;
- development proposals affecting neighbouring properties;
- rights-to-light considerations;
- planning policy assessments;
- reviewing proposed developments and planning documents;
- preparing representations to the local planning authority; and
- advising on planning and property issues arising alongside development proposals.
Where a matter involves a potentially enforceable private right to light, specialist legal and surveying advice may also be appropriate.
Frequently Asked Questions
Can I object to planning permission because a development will block my light?
Potentially. Loss of daylight or sunlight can be relevant to a planning application where the impact is considered unacceptable. The strength of the objection will depend on the circumstances of the development and the relevant planning policies.
Is a right to light the same as a right to receive sunlight?
Not necessarily. A legal right to light concerns natural light passing through a defined opening and is a private legal right. Planning considerations concerning daylight and sunlight are assessed separately through the planning system.
Can I have a right to light without having a written agreement?
Potentially. Rights to light can arise in various ways, including prescription, so the absence of an express written grant does not necessarily mean that no right exists.
Does planning permission mean my neighbour can build regardless of my right to light?
Planning permission does not necessarily resolve separate private rights. A right to light may operate independently of the planning system.
Should I obtain a specialist assessment?
For significant developments, a daylight and sunlight assessment or specialist rights-of-light assessment may help establish the likely impact. The appropriate evidence will depend on the nature and scale of the proposal.
Protecting Your Property Interests
A proposed development can affect neighbouring properties in several ways, and loss of natural light can be an important consideration.
However, a planning objection and a private right-to-light claim are not the same thing. Understanding the distinction can help property owners identify the correct route, gather appropriate evidence and raise relevant concerns before a development progresses.
If a proposed development is likely to affect the daylight or sunlight enjoyed by your property, obtaining professional advice at an early stage can help you understand your planning position and potential rights.
