HC Deb 15 February 1980 vol 978 c854W
Mr. Alton

asked the Secretary of State for the Home Department what is the per capita unit cost of the provision of a nuclear shelter; how many people could be provided for; and which people would be given cover.

Mr. Whitelaw

Costs would vary according to size, material, mode of construction and situation. Limited research on a reinforced concrete shelter, fully sunk, for a family of six, indicates an order of cost of £1,000 per head. That cost might be lower for a range of possible improvisations or for larger designs for public use. The question of shelter provision is being examined in my current review of home defence arrangements.
