§ The Parliamentary Under-Secretary of State, Department of the Environment (Lord Hesketh)Amendments to the relevant part of the Building Regulations 1985 were made last July, and are due to come into operation on 1st April 1990.

The Home Insulation Scheme has provided grants for loft, tank, and pipe insulation in existing houses, and we estimate that around 90 per cent. of accessible lofts are now insulated. The scheme is being replaced by discretionary grants for a wider range of insulation measures under the Local Government and Housing Act 1989 and by the848WA proposed new scheme of grants towards the cost of basic insulation measures in low income households recently announced by my right honourable friend the Secretary of State for Energy.
