§ Mr. Wilson
asked the Secretary of State for Scotland (1) how many Scottish housing authorities have submitted claims to the National Coal Board for compensation because of reduced value of housing stock resulting from mining subsidence;
(2) if he will give figures, at the latest available date, to show the number of houses in Scotland with shared cold water storage tanks; and how many have undersized or sub-standard cold water storage tanks;
(3) how many houses in Scotland, at the latest available date, have obsolete or defective electrical wiring;
(4) how many Scottish houses which adjoin have no firewall within the roof space.
§ Mr. Wilson
asked the Secretary of State for Scotland if he will give figures at the latest available date to show (a) how many houses in Scotland lack adequate loft insulation and how many have no loft insulation, and (b) how many houses have uninsulated cold storage tanks and loft pipes.
§ Mr. Ancram
Information is not collected centrally, but an estimate made by a private firm — Audits of Great Britain Ltd. —on the basis of a sample survey carried out in December 1982 indicated that some 948,000 houses in Scotland with loft spaces were without loft insulation or had less than the 100m thickness which building standards regulations introduced on 28 March 1983 now require for new housing.
No information is available on the number of houses lacking cold water storage tank or pipe insulation.
