I haven't read the legislation. But a quick google suggests the lawyers are right:
The fees ban applies to all new tenancies entered into on or after 1 June [2019].If you signed a tenancy before this which included agreements to pay further fees – for example, check-out fees or tenancy renewal fees – you will still have to pay these up until 31 May 2020.
But from 1 June 2020, any term in a tenancy which requires you to pay fees will no longer be binding, so you won't need to pay them regardless of what your agreement says or when you signed it.
Biting the hand that feeds IT
