asked the Secretary of State for the Environment what guidance he has given to local authorities about increases in housing services for the year 1975–76.

I would refer my hon. Friend to Circulars 74/74; 160/74; 171/74, paragraphs 42 to 44; 13/75 and 14/75; and to the Housing Rents and Subsidies Act 1975. I shall shortly be issuing a further circular to local authorities advising them on various measures to produce more houses more quickly and more cheaply.
