§ Mr. Gwilym Robertsasked the Secretary of State for the Environment if he will list the number of new installations of loft or cavity wall insulation undertaken in each year between 1978 and 1981.
§ Sir George YoungThe information is as follows:
Cavity Wall Insulation (000's homes) Loft Insulation (000's homes) 1978 77 680 1979 99 792 1980 150 668 1981 * * * No figures are available for the whole of 1981. Source:Audits of Great Britain Ltd.
§ Mr. Gwilym Robertsasked the Secretary of State for the Environment to what factors he attributes the decline in the number of new installations of loft or cavity wall insulation undertaken in 1980 and 1981, compared with 1978 and 1979.
§ Sir George YoungThe number of cavity walls insulated in 1980 is considerably greater than the number insulated in 1978 or 1979.
The number of lofts insulated in 1980 was similar to that insulated in 1978; the higher number insulated in 1979 may be attributed to an exceptional number of loft insulations by local authorities in that year.
On present information, the annual rates of cavity wall and loft insulation for 1981 will be similar to those for 1980.
