asked the Secretary of State for the Environment what is his latest estimate of the number of homes which are felt to be unfit for human habitation and the number so seriously affected by damp as to present marked discomfort or disadvantage to their occupants.
In the 1981 English house condition survey it was estimated that in 1981 some 1·1 million dwellings—6 per cent. of the stock—were unfit for human habitation. There is no readily available estimate of the total number of dwellings affected by damp sufficient to be a discomfort or disadvantage to their occupants.
However, the survey indicated that 10 per cent. of households considered themselves to be troubled by damp.
