Many landlords believe that to change agents you must wait until the end of an existing tenancy, which is not the case.
A Tenancy Agreement is a contract between the Landlord and the Tenant, and changing agent does not affect the legal rights of either.
If a letting agent has not been delivering on service, it is likely that the tenant will be pleased that the management is changing and they may be more likely to stay in the property longer. Once you have given your agent written notice that you would like to leave, we’ll take it from there!
