asked the Secretary of State for Energy what is his estimate of the additional resources which would be required to ensure that the backlog of inadequately insulated homes occupied by households on low incomes would be properly insulated over the next five years.

I refer the hon. Member to my answer of 1 December 1986 at column 455–56.

asked the Secretary of State for Energy how many houses have been insulated since 1979 with assistance under Government schemes.

Since 1979 approximately 3 million households in Great Britain have received grants for loft insulation under the homes insulation scheme, and since my Department began its programme of support for community insulation projects in 1981, this movement has insulated 300,000 homes of low income households.
