A statutory implied covenant applied to certain tenancies at a very low rent (Landlord and Tenant Act 1985 s 8). Premises are regarded as not reasonably fit for habitation if they are defective in one or more of the following: repair, stability, freedom from damp, natural lighting, ventilation, water supply, drainage and sanitary conveniences, facilities for cooking and for storage and preparation of food, and disposal of waste water. A landlord normally has no obligation to see that premises are fit for habitation when the statutory provisions do not apply. There is an implied term that tenancies of furnished dwelling houses are fit for habitation at the commencement of the tenancy. The environmental health officer employed by the local authority can order the landlord to carry out repairs. See housing health and safety rating system.
