A tenancy will be assured if, subject to other criteria, the property is let as a separate dwelling to a natural person who occupies it as their only or principal home: section 1 of the Housing Act 1988 (HA 1988). HA 1988, Sch 1 Pt I sets out various tenancies which cannot be assured, despite meeting the other conditions. These include (at HA 1988, Sch 1 Pt I, para 3A) tenancies at a low rent. Subject to conditions about when the tenancy was entered into, a tenancy cannot be assured if ‘the rent payable for the time being is payable at a rate of, if the dwelling-house is in Greater London, £1,000 or less a year and, if it is elsewhere, £250 or less a year’. Section 186 of the Local Government and Housing Act
