Landlords are losing the vast majority of rent tribunal cases brought since January 2025, with new analysis from LonRes finding that 73% of decisions have resulted in lower rents than those originally proposed. More strikingly, 47% of rulings explicitly cited evidence problems as a factor in the outcome. For a sector already grappling with the fallout of the Renters' Rights Act, this data offers the clearest signal yet that the balance of power in rent-setting disputes has shifted decisively towards tenants — and that many landlords are simply unprepared for the new regime.
