§ Mr. Mike Thomasasked the Secretary of State for the Environment in view of the Government's policies on energy conservation and insulation, whether he will take steps to collect the information necessary for him to ensure that dwellings constructed by local authorities are adequately heat insulated.
§ Mr. ArmstrongWhether a new dwelling can be regarded as adequately insulated depends on a number of considerations, including how well its heating system is matched to the dwelling design and construction. It would be difficult and costly to collect information on this for each new dwelling. However, all new dwellings must have, as a minimum, insulation standards which conform to the Building Regulations; and in the case of new electrically heated dwellings recommendations on levels of insulation were included as part of the advice in Domestic Energy Note No. 1, produced by the Joint Working Party on Heating and Energy Conservation in Public Sector Housing.
