Landmark High Court Appeal decision: Why this property litigation case matters

By Richard Owen – Senior Associate

Published 8th April 2026

Richard Owen a property litigation expert from HM3 Legal, successfully acted for the Appellant landlord and management company in this important case which explored the meaning of property ‘disrepair/repair’.

The long leaseholders of a block of purpose-built student accommodation brought a claim against HM3’s clients (the freeholder and the management company) regarding the deterioration of the windows at the development. The windows had failed causing a loss of gas from between the panes, and condensation. The issue on appeal was whether this amounted to ‘disrepair’ (the leases required the leaseholders to keep their properties in repair).

On appeal, Mr Justice Rajah found that disrepair had been made out even though the issues could be traced back to installation defects which were present when the leases were granted.

Who pays for remedial property works?

The case is important because the landlord intends to carry out significant remedial works to the building in question. Had the Court found that the long leaseholders were not in breach of their repairing covenants, it would have been necessary for the landlord to finance the remedial works from its own funds (rather than being able to recoup those costs from the leaseholders via the service charge).

Why choosing a specialist property litigation lawyer matters

Landlord and tenant disputes are often legally and factually complicated. A specialist lawyer understands:

  • The obligations which a lease places on both the landlord and the tenant.
  • The nuances of legislation and case law relating to service charges and the concept of ‘repair/disrepair’.
  • How to instruct expert witnesses and interpreting expert evidence given by the opposing party.

Without this expertise, various things can go wrong including:

  • One-sided or incomplete expert evidence may be accepted by the Court.
  • Missed procedural steps may result in the loss of the proceedings or costs sanctions.
  • Failure to identify relevant precedent cases may result in the Court reaching an incorrect decision.

Of crucial importance in this case was Mr Justice Rajah’s finding that the trial Judge’s findings had been consistent with the deterioration of the windows being progressive in nature.

This landmark case demonstrates that expert legal advice must be sought when entering into a commercial property agreement, when understanding the nuances of any property agreement and also to guide parties through the due legal process should a commercial property dispute ever arise.
