§ 27. Mr. Newtonasked the Secretary of State for the Environment what estimate he has made of the scope for further energy saving by improve insulation of existing domestic properties.
§ Mr. ArmstrongWe estimate that more than 5 per cent. and perhaps as much as 10 per cent. of total fuel consumption in housing would be saved if currently cost effective techniques of thermal insulation were applied to those existing dwellings where this has not already been done.
