§ Mr. BarronTo ask the Secretary of State for the Environment what percentage of homes in England and Wales have central heating.

(2) what is the number and percentage of dwellings in England and Wales that lack cavity wall insulation.
§ Mrs. RoeThe available figures are based on a sample survey conducted by Audits of Great Britain Ltd. in December 1986. It is estimated that 59 per cent. (11.2 million) of households in England and Wales lacked draught-stripping to doors and windows, although many doors and windows do not need draught-stripping to make them draught proof, and that 55 per cent. (10.4 million) of households had cavity walls that were not insulated.
§ Mr. BarronTo ask the Secretary of State for the Environment what are the latest regulations regarding loft insulation; and what proportion of homes in the United Kingdom are insulated to this standard?
§ Mrs. RoeThe current building regulations require a U-value of 0.35 which is achieved by 100mm mat insulation or its equivalent; all new homes are insulated to this standard. It is estimated from a sample survey conducted by Audits of Great Britain Ltd., in December 1986, that 44 per cent. of housholds with access to loft spaces in Great Britain had 4in (approximately 100mm) or more of insulation.
