asked the Secretary of State for the Environment how many houses formerly subject to Rent Act control in England and Wales have become decontrolled since June 1970; and how many new houses completed since that date are subject to some form of statutory control.

It is estimated that since June 1970 about 800,000 controlled tenancies have ended or been converted into regulated tenancies. No information is available on the number of dwellings completed since 1970 which are let on tenancies subject to the Rent Acts.
