How Courts Decide Between an Injunction and Damages in Rights of Light

By Daniel Peddlestone · 25 August 2026

When a court finds that your right of light has been infringed, it must decide what remedy to grant. This decision matters enormously. An injunction could force a developer to cut back or even demolish part of a building. Damages, on the other hand, mean you receive a financial payment but the offending structure stays put. Understanding how courts approach this choice helps you assess the realistic strength of your position.

The starting point is that an injunction is the primary remedy for interference with a property right. Courts have long treated rights of light as genuine property rights, not just interests that can be bought off with money. The leading modern authority on when damages should be awarded instead of an injunction is the Supreme Court decision in Coventry v Lawrence (2014), which revisited the older principles from Shelfer v City of London Electric Lighting Co (1895). Under Shelfer, damages could replace an injunction where the injury was small, capable of being estimated in money, and where an injunction would be oppressive. But Coventry v Lawrence made clear that Shelfer should not be applied mechanically. Courts now have a broader discretion.

In practice, this means the court looks at the whole picture. How serious is the loss of light? Did the developer know about your right and press ahead anyway? Would an injunction cause disproportionate harm compared to the benefit you would receive? A developer who builds in full knowledge of your rights and gambles on paying damages later may find a court less sympathetic. Courts have repeatedly said they will not allow developers to "buy" the right to infringe by calculating damages into their project costs.

The concept of proportionality plays a central role. If a large mixed-use scheme affecting hundreds of homes would need to be partly demolished to restore adequate light to a single small window, the court may decide that damages are the fairer outcome. But if the infringement is significant, affecting the usability of your rooms, and the developer acted in bad faith, an injunction becomes much more likely. You can read more about your legal rights as a property owner and how these protections apply in different situations.

Timing also matters. If you bring your claim before construction is complete, a court is far more willing to grant an injunction because the cost of compliance is lower. Once a building is finished, courts must weigh the waste involved in ordering demolition. This does not mean post-construction claims are hopeless, but it does shift the balance. Acting promptly strengthens your position significantly.

The financial remedy, when awarded in lieu of an injunction, is not simply the diminution in value of your property. Courts assess what a reasonable person in your position would have accepted as a one-off payment to release the right. This hypothetical negotiation approach often produces figures well above straightforward diminution in value, because it reflects your ability to block the development entirely. If you want to understand how compensation is calculated, this negotiating framework is central to the method surveyors and lawyers use.

The question of the developer's conduct runs through all of this. A developer who engages with affected neighbours early, offers reasonable compensation, and tries to minimise the impact will generally face a court more inclined towards a damages award. A developer who ignores correspondence, rushes to complete building works, or dismisses your rights entirely may find the court reaching for an injunction precisely to discourage that behaviour.

If you are unsure whether your situation could support an injunction claim or would more realistically result in damages, the first step is understanding what a right of light is and confirming that yours has been established through long use or express grant. From there, a specialist surveyor can assess the degree of interference, and a solicitor can advise on the likely remedy a court would grant based on the specific facts.

Every case turns on its own circumstances. But knowing how courts balance these factors puts you in a stronger position to negotiate, whether you ultimately want to stop a development or secure proper financial recognition for the loss of light to your property.
