§ Mrs Renée Short
asked the Secretary of State for the Environment how many people insulated their lofts in 1977, 1978 and 1979; and how many people did so with the aid of a grant in 1978 and 1979.
§ Mr. Geoffrey Finsberg
Following are the available estimates:

(AGB). These estimates are based on a sample of households and are therefore subject to sampling error. † Number of dwellings on which work has been completed under the public sector energy conservation programme. Local authorities' estimates, submitted to the Department of the Environment. ‡ Numbers of grants paid under the homes insultation scheme. Local authorities' estimates, submitted to the Department of the Environment. § The estimates in the two columns for 1979 are not expected to be the same. Some grants paid in 1979 will refer to work completed in 1978. Local authorities' interpretation of work completed may not be identical to households. || An annual estimate based on returns for the first three quarters.
