Could a Loss of Light Claim Be Worth Compensation?

What drives the value of a rights of light claim, why every case is different, and what to be cautious of.


How Compensation Is Calculated

There is no fixed formula for calculating compensation in rights of light claims. Courts assess damages on a fact-specific basis, and the range of outcomes across different cases is wide.

The most common approach is to assess what a reasonable buyer would have paid to acquire a release of the right before the development commenced — sometimes called a "negotiating damages" basis. This can involve a notional negotiation reflecting a share of the development profit, which can be substantial for large commercial schemes.

What Affects Claim Value?

Severity of light loss
The technical extent of the reduction in daylight, assessed by specialist surveyors using daylight modelling software.
Type and value of the property
A rights of light claim in a high-value residential or commercial area will typically involve larger sums.
Scale and nature of the development
A large commercial development with significant development value has more at stake than a small residential extension.
Strength of the legal claim
Evidence of long use, the nature of the apertures, and prior challenges all directly affect claim value.
Negotiation context
The developer's timetable, funding arrangements, and exposure to injunction risk all influence settlement negotiations.
Litigation risk
The possibility of adverse costs and appeals must be weighed against the potential recovery. Specialist advice on this is essential.

Negotiation vs Litigation

The majority of rights of light claims are resolved by negotiation before reaching court. The prospect of an injunction gives claimants with strong cases significant leverage, particularly before or during construction.

Once a development is substantially complete, courts are generally less willing to grant injunctions and damages become the primary remedy. This is why early action is important.

Key principle

Compensation in rights of light cases is typically assessed by reference to what a reasonable buyer would have paid to acquire a release of the right — not simply the diminution in property value.
