REAL ESTATE DISPUTE RESOLUTION

Rights of Light – key takeaways from case of Cooper and Powell v Lugate House Ltd

On 8 July 2025, the High Court handed down its much-anticipated judgment in the case of Cooper and Powell v Ludgate House Ltd [2025] EWHC 1724 (Ch).

The decision, whilst not considered controversial, is significant for property owners, rights of light practitioners and developers. It highlights the court’s approach to rights of light disputes in the context of major urban redevelopment; providing an insight into how it seeks to strike a balance between private rights, public interest, and modern construction pressures, and also revealing the potential sums property owners could claim against neighbouring developments.

Right of Light

A right of light is a legal easement that protects a landowner’s right to receive natural light through defined openings (like windows) in buildings on their land across neighbouring land. If a property has received uninterrupted light for at least 20 years, this right becomes legally established. A property owner may have a claim against a neighbour whose new development significantly blocks or reduces access to this light. Remedies for interference can include an injunction to stop the development or compensation (damages).

The Facts

Mr Cooper and Mr and Mrs Powell were leaseholders in Bankside Lofts on London’s South Bank. Their flats, which had enjoyed uninterrupted light for decades, were significantly overshadowed by the Arbor building, which was constructed in 2022 as part of the Bankside Yards regeneration.

Mr Cooper and Mr and Mrs Powell brought claims against the developer of the Arbor building, Ludgate House Ltd, on the basis that the building infringed their prescriptive rights of light. They both sought an injunction requiring Ludgate House Ltd to demolish substantial parts of the Arbor building, or compensation based on the diminution in value of their flats caused by the nuisance.

Crucially, the Arbor building lacked protection of a statutory power under Section 203 of the Housing and Planning Act 2016 (which did apply to the remaining planned development). This meant that, although the site had been acquired by the council for planning purposes (after construction of the Arbor building), rights of light claims in relation to the Arbor building itself would not necessarily be converted into a right to compensation rather than an injunction (and any compensation would not necessarily be based on the diminution in value of the affected property).

Mr Cooper and Mr and Mrs Powell submitted that the buildings yet to be constructed as part of the development, and which were subject to Section 203 (enabling the development to proceed despite the interference to neighbouring property rights) should not be taken into account.

The court held that in assessing whether the Arbor building caused actionable loss of light, the correct approach was to disregard light that would inevitably be lost due to the Section 203 protected development, as Mr Cooper and Mr and Mrs Powell could not protect that light.

The Outcome

The court found an actionable nuisance through interference with both Mr Cooper’s and Mr and Mrs Powell’s rights of light.

An injunction (i.e. demolition or forced modification of the Arbor building) was refused on the basis that it would be disproportionate; the harm caused to the Arbor building and its tenants by the grant of an injunction, along with the public interest in retaining the building (e.g. zero-carbon design and local employment) outweighed the harm caused to Mr Cooper and Mr and Mrs Powell by the interference with their light. It was also noted that a Section 203 resolution could make the right unenforceable in future stages of development (i.e. the Arbor building was likely to be rebuilt with Section 203 protection if demolished).

Mr Cooper and Mr and Mrs Powell were awarded damages in lieu. Notably, they were not awarded damages for diminution in value of their flats (as argued by Ludgate House Ltd), but instead ‘negotiating damages’ based on what a reasonable price would have been for the claimants to give up their rights.

Mr Cooper received £350,000 and Mr and Mrs Powell received £500,000. These figures dwarfed the diminution in value figures put forward by Ludgate House Ltd (£20,000 and £60,000 respectively) and are believed to be the highest ‘negotiating damages’ ever awarded in a residential right of light claim.

The Implications

Whilst not legally groundbreaking, Cooper and Powell v Ludgate House Ltd confirms some well-established principles and offers several key lessons for both developers and property owners:

  • Injunction: Is not a guaranteed remedy, even when interference is serious.
  • Damages/Negotiating Damages: The court is willing to use this remedy in place of an injunction, particularly in large-scale developments and the award can be substantial. Further, ‘negotiating damages’ is established as the correct approach to the award of damages when the right to enforce an easement has been lost.
  • Statutory protection: A warning that developers who build without having secured the necessary releases or statutory protection for rights of light face substantial financial risk. Developers cannot rely on overall site-wide light conditions if only some buildings benefit from Section 203 protection.
  • Timing: The fact that the Arbor building was constructed before the section 203 resolution was a key factor. Developers cannot apply subsequent statutory protection to a pre-existing infringement of rights, which affects potential enforceability and remedies available.
  • Waldram: Despite a technical debate over modern metrics (which I have not discussed in this blog), the traditional Waldram method for assessing rights of light remains the core legal test for the courts.

Conclusion

While Ludgate House Ltd managed to avoid an injunction, the case is a warning to developers operating without the protection of Section 203. The judgment confirms that in such scenarios, affected neighbours may be awarded substantial negotiating damages calculated not by a simple diminution in property value, but relative to a share of the developer’s gain.

The case may see developers, particularly those building without the statutory protection, being pressured into early and robust negotiations by more aggressive neighbouring property owners, who will now have a heightened sense of the potential money at stake.
