§ Mr. RostTo ask the Secretary of State for Energy what proportion of eligible homes in England and Wales currently have(a) cavity wall insulation, (b) 150mm of loft insulation, (c) thermostats on 50 per cent. or more radiator valves, (d) double glazing on 50 per cent. or more external windows, (e) compact fluorescent lighting in 50 per cent. or more light fittings, (f) energy labelling on domestic electrical appliances, (g) gas condensing boilers and (h) floor insulation; and by when he forecasts that each of these figures will reach 75 per cent. and 90 per cent. of the eligible market.
§ Mr. Heathcoat-AmoryIt is estimated that some 19 per cent. of eligible homes in England and Wales have cavity wall insulation, 43 per cent. have four inches or more of loft insulation, 30 per cent. have double glazing installed in 40 per cent. or more rooms, less than 1 per cent. have compact fluorescent lighting in 50 per cent. or more light fittings, and less than 5 per cent. have gas condensing boilers. No figures are available for thermostatic radiator valves or floor insulation. Energy consumption information is provided in brochures or leaflets by manufacturers for the most important energy consuming domestic electrical appliances.
The Government have made no forecasts of when such energy efficiency measures will achieve particular levels of domestic market penetration.
