216.Section 94 permits a local authority to serve a notice on the landlord, tenant and any agent if the landlord is not registered and is letting or allowing occupation of a house and it is appropriate to serve a notice in all the circumstances. The effect of the notice is that no rent or other payment is payable under the tenant’s lease or occupancy arrangement from a specified date. No other aspect of the lease or occupancy arrangement is affected. A notice cannot be served if the person has applied for registration and the application has not been determined. The section also provides for notification arrangements where the landlord’s identity or current address is unknown.
