Mr. Alan W. Williams
To ask the Secretary of State for the Environment, pursuant to the answer to the hon. Member for Carmarthen by the Parliamentary Under-Secretary of State for Energy, the hon. Member for Wells (Mr. Heathcoat-Amory) on. 2 December at column 42, on energy efficiency investment, if he will break down the figure of £900 million into its component parts.
§ Mr. Yeo
A breakdown of the figure of £900 million for the financial year 1990–91 is not available. However, the 1986 English house condition survey indicated that of all major expenditure on the public sector stock, directed at the improvement of heating and insulation, some 73 per cent. was for installing or repairing central heating and nearly 9 per cent for other heating. Around 17 per cent was spent on wall insulation and some 1 per cent on loft and roof insulation.
