asked the Secretary of State for the Environment what is his estimate of the proportion of rented accommodation in the United Kingdom at present offered by private landlords who themselves live on the premises; and what would be the approximate extra cost to the Exchequer if such rented accommodation were provided through local authorities or housing associations.

The General Household Survey of 1972 estimated that of the privately rented accommodation in Great Britain 9 per cent.—representing 3 per cent. of the total rented stock, both public and private, in Great Britain—was supplied by landlords who lived on the premises. The cost estimate sought by the right hon. Member cannot be made, as local authorities and housing associations do not normally provide such accommodation as is supplied by resident landlords.
