Part 8 requires each local authority to establish a register under this Part showing registered persons and the houses they let, and make it available for public inspection. Any person can apply to be registered. The local authority must be satisfied prior to registration that the person is fit and proper to act as a landlord, and that any agent declared by a landlord is also fit and proper. The local authority may remove a person who is no longer fit and proper from the register. A private landlord who lets a house without being registered is committing an offence unless he or she has applied for registration and the application has not been determined by the local authority. The local authority may serve a notice that no rent is payable on such a landlord, and on the tenant and any agent. The notice does not affect other terms of the lease.
