§ Mr. LlwydTo ask the Secretary of State for Environment, Food and Rural Affairs what assessment she has made of(a) how much is invested annually into household energy efficiency and (b) how this money is spent. [25625]
§ Mr. MeacherThe Government estimate that during 2000 (the most recent year for which figures are available) the total investment in household energy efficiency measures was approximately £250 million (excluding double glazing). The breakdown for the major items of this expenditure is:
£million Loft insulation 90 Cavity wall insulation 70 Lighting 50 Draught proofing 20 Condensing boilers1 10 Tank insulation 5 1 This figure includes only the fraction of the total cost of the boiler assumed to represent the additional cost of the increased energy efficiency. Although installing double glazing in homes does increase the energy efficiency of the building it is rare that double glazing is installed for energy efficiency reasons alone. Hence, expenditure on double glazing is excluded from the figures. However, the Government estimate that the energy efficiency component of double glazing installations totals some £500 million p.a.
