The Tenants Fees Act also made it illegal for landlords and agents to charge tenants ‘check out fees’. If your tenancy was entered into before 1 June 2019, any renewal fees agreed at the time will be payable – but only until 31st May 2020.
You should challenge your landlord or letting agent if you believe that they are trying to charge you an unlawful fee. You can also contact Citizens’ Advice for more help dealing with unscrupulous landlords and agents.
