BackdatedThe new rent took effect from 1 February 2026, before the decision was made. Backdating was allowed under the pre-Act rules.

In short

The landlord proposed raising the rent from £475 a month to £750 a month from 1 February 2026. The tribunal determined a rent of £700 a month, effective from 1 February 2026, for a two-bedroom ground-floor flat in SW17. It gave more weight to the landlord's comparables than the tenant's, valuing the property at £2,800 a month in modernised condition, and applied a 75% deduction for its extremely poor condition.
