HC Deb 20 December 1982 vol 34 c310W
Mr. Viggers

asked the Chancellor of the Exchequer what would be the cost in the financial year 1983–84 and in succeeding full financial years of raising the permissible office content for buildings which qualify for industrial building allowance from 10 per cent. to 30 per cent.

Mr. Ridley

I regret that insufficient information is available upon which to base any estimates of cost.
