§ Mr. Sainsburyasked the Secretary of State for the Environment what proportion of the expenditure on the programme of enery conservation in the civil and defence estates will be on cavity wall insulation.
§ Mr. MarksOur records are not collated in a form which readily distinguishes one type of energy conservation measure from another. In general, however, we expect to devote about 20 per cent. of our planned expenditure on the civil and defence estate, other than married quarters, to cavity insulation measures in 1978–79. This proportion is likely to reduce in future years.
On Service married quarters, we expect to devote about two-thirds of our planned expenditure on energy conservation measures to cavity insulation and this proportion is likely to increase over future years.
§ Mr. Sainsburyasked the Secretary of State for the Environment whether the expenditure on cavity wall insulation in public sector housing will be eligible for central Government housing subsidies 248W under his programme of enery conservation.
§ Mr. ArmstrongNo. Cavity wall insulation is not included among the basic measures being undertaken under the first stage of the Government's energy conservation programme for local authority, new town, and housing association dwellings.
