In short

The landlord proposed a rent of £2,597 a month, up from £1,520 a month, for a three-bedroom flat in SM5. The tribunal determined a market rent of £1,700 a month from 5 December 2025, after valuing the flat in modernised, good order at £1,800 a month and reducing that by 5% for condition matters including bathroom mould with no mechanical extractor fan and damage to the external staircase. The tribunal relied on its own expert and general knowledge of local rents, as the landlord provided no comparables.
