Right to Light Surveyors London
We have assisted Developers and Neighbouring Owners in right-to-light disputes in London and across the UK for over a decade.
From large commercial schemes in Central London to smaller infringements between neighbours, we have a wealth of experience.
What is a Right to Light?
A Right to Light is a negative easement and a legal right to a property.
Usually established via prescription (20 years of use) under the Prescription Act 1832, if a nuisance is caused by neighbouring development, the injured party can seek a remedy for their loss.
They may wish to seek injunction over the offending structure, which creates a risk for the developer, however the dispute will typically result in a cash settlement.

What is a Right to Light Survey?
A Right to Light Survey assesses whether a building or proposed development might interfere with a neighbour’s legal right to adequate natural light.
In the UK, the right to light is an easement, meaning a property owner may have a legal right to sufficient daylight reaching their property’s windows.
If a new development blocks this light, the affected property owner can claim compensation or seek an injunction to halt the construction.
The survey involves analysing the proposed development’s impact on the light surrounding properties receive.
This is done through specialist techniques, such as mapping and computer simulations, to measure the amount of daylight entering windows before and after the development.
Surveyors use tools like the 45-degree rule or the Waldram diagram to assess whether a neighbour’s light will be obstructed.
These surveys are particularly important in urban areas where buildings are close together, and even minor changes to neighbouring structures can significantly affect light levels.

Advising Neighbouring Owners
We regularly provide help to property owners whose rights are infringed upon by a development.
Typically, a developer will want to reach an agreement over any Right of Light infringements they are causing to remove this legal liability from their scheme.
This will usually be in the form of monetary compensation.
Unfortunately, it isn’t always this simple.
Developers will sometimes obtain Right of Light insurance and keep quiet about infringements, allowing them to press on with development.
So it is important to be proactive and raise the issue.
At Blackacre, we appreciate the value of light, particularly to people in our cities.
We have spent many years specialising in negotiation with developers, seeking to ensure our clients receive a fair settlement for their losses.
Of course, if a property owner’s rights are infringed and a nuisance caused, they are entitled to seek an injunction over the offending party; however, this isn’t always the most practical solution.
