AI confidence in this short overview: high
This appeal concerned whether a landlord could recover, by service charge, costs it had incurred providing temporary accommodation and storing belongings of basement flat occupiers while carrying out damp‑proofing repairs. The Upper Tribunal held the First‑tier Tribunal erred: those ancillary costs fell within the leases’ service‑charge clauses as expenditure “in performing” the landlord’s repairing obligations and alternatively as reasonable discretionary expenditure for the general benefit of the building. The appeal was allowed, the FTT decision set aside, and the leaseholders were held liable to contribute (quantification was not determined).
Ratio decidendi
This summary is intended to identify the ratio decidendi, meaning the legal reasons for deciding and the binding part of the decision.
AI confidence in this ratio decidendi summary: high
The binding ratio is that ancillary costs necessarily or reasonably incurred to enable the landlord to perform its repairing obligations — for example removal, storage and temporary rehousing of occupiers during repair works — fall within a lease clause obliging tenants to pay expenditure “in performing the landlord’s obligations as to repair.” In addition, where a lease permits recovery of expenditure which the landlord reasonably deems necessary for the general benefit of the building, the landlord may recover discretionary costs incurred to facilitate or expedite repairs if that decision is reasonable.
Obiter dicta
This summary is intended to identify obiter dicta, meaning observations made by the way that were not necessary to deciding the case and are not binding.
AI confidence in this obiter dicta summary: medium
The tribunal observed (obiter) that a landlord’s reasonable choice about how to perform repair covenants can make otherwise non‑essential expenditure recoverable, and that the availability of a separate defence (for example to a damages claim if tenants refused to move) is irrelevant to the question whether rehousing costs were recoverable by service charge. It was also suggested that expenditure need not be strictly necessary to be reasonable.
