§ Mr. Ernie Rossasked the Secretary of State for Scotland (1) what is his estimate of the number of houses in Scotland affected by dampness; and in how many instances the dampness has resulted from condensation;
(2) if he will provide a percentage breakdown by housing tenure of the number of houses in Scotland affected by dampness.
§ Mr. Allan StewartOn the basis of incomplete local authority checklist returns, I estimate that about 156,000, or 17.3 per cent., of local authority houses are affected to some extent by condensation, and 17,000 or 1.9 per cent. (many of which will be included in the former total) by rising or penetrating dampness. No information is available for other tenure groups.
