If you are a private landlord or a tenant, your rights and obligations are governed largely by the Landlord and Tenant Acts of 1954 and 1985. If the property concerned is an HMO (House in Multiple Occupation – defined as being a residential building housing at least 3 tenants living in separate ‘households’ and sharing toilet, bathroom or kitchen facilities) special additional regulations apply.
If you live in a flat or apartment which has been, or is being, purchased for a capital sum on a long-term leasehold basis you are not a tenant for the purposes of the 1954 or 1985 Acts. For you, the Landlord and Tenant Act 1987, which deals mainly with the rights of leaseholders to acquire freehold status from their landlord, applies.
Whether you are a landlord or a tenant, contentious issues may arise between you and your ‘opposite number’. The law can be complex and involved since the above listed, and other, Acts of Parliament have been augmented over the years by case law which enhances and develops the statutes.
