asked the Secretary of State for the Environment what is the latest estimate of the percentage of homes which (a) have no loft insulation, (b) have loft insulation which is not thick enough to meet the 1982 Building Regulations requirement and (c) have adequate loft insulation.
It is estimated that, at December 1980, of the 15·8 million homes in Great Britain with accessible loft 30 per cent. had no loft insulation, and 57 per cent. had insulation below the 100 mm standard in the 1982 building regulations. Whilst the remaining 13 per cent. of homes have insulation of at least 100 mm, the adequacy of this would depend on individual circumstances.
asked the Secretary of State for the Environment how much has been spent on loft insulation grants for each of the last five years at current prices; and what is the intended amount for 1982–83.
The scheme began in September 1978. The amounts spent on grants since then in England at current prices are as follows:
| £ million | |
| *1978 | 8·3 |
| 1979–80 | 14·1 |
| 1980–81 | 15·5 |
| †1981–82 | 15·7 |
| * 18 September 1978–1 April 1979. | |
| † First nine months only. | |
