§ Lord Melchettasked Her Majesty's Government:
What is their best estimate, or if they have none, what estimates have been made by public bodies, of the total costs, including all training, supervision, labour, materials and all other capital costs, at 353WA 1980 prices, of insulating all homes in Great Britain to currently approved standards, how many years it is estimated such a programme might take to complete, and how many additional jobs (in terms of full-time jobs per year) would be created while this work was being done.
§ The Earl of AvonThere are no approved standards for insulating existing homes. Grants are made under the Home Insulation Scheme for insulating lofts and associated hot water tanks. It is estimated that the total costs at 1980 prices of these measures would be of the order of £450 million.
Current projections suggest that the measures should be largely completed within 5 to 10 years.
The number of additional jobs that would be created would depend on how much of the insulation work was carried out by householders themselves.
