Tribunal Outcomes
Real First-tier Tribunal (Property Chamber) decisions showing what managing agents demanded versus what the tribunal allowed. Residents can and do successfully challenge unreasonable charges.
Ref: LON/00AY/LSC/2023
| Item | Demanded | Adjusted | Saved |
|---|---|---|---|
| Management Fee | £2,630 | £1,315 | −£1,315 (50%) |
| Common Electricity | £1,383 | £360 | −£1,023 (74%) |
| Health & Safety Testing | £724 | £120 | −£604 (83%) |
The tribunal found systematic overcharging across multiple service charge heads, with the landlord unable to provide adequate documentation for the amounts demanded. Total reduction of approximately 60% across challenged items.
Ref: LON/00BJ/LSC/2022
| Item | Demanded | Adjusted | Saved |
|---|---|---|---|
| Management Fees (as billed) | £19,974 | £365 | −£19,609 (98%) |
A landmark case exposing how some agents embed undisclosed costs within 'management fees'. The warden service charge was hidden inside the management fee line item, meaning leaseholders were unknowingly paying for a service they hadn't agreed to. The tribunal ruled the true management fee was £365/flat — a 98% reduction from the billed amount.
Ref: LON/00AW/LSC/2023
| Item | Demanded | Adjusted | Saved |
|---|---|---|---|
| Residential Unit Annual Charge (2021) | £1,516 | £1,516 | — |
| Residential Unit Annual Charge (2022) | £1,594 | £1,594 | — |
| Residential Unit Budget (2023) | £1,922 | £1,700 | −£222 (12%) |
The tribunal accepted modest year-on-year increases (5.1%) but rejected a sudden 20.5% budget increase where the managing agent could not justify the acceleration. This sets an important precedent: agents must evidence why costs are increasing faster than inflation.
