§ Mr. Skeetasked the Secretary of State for Energy what is the return on net assets achieved by the British Gas Corporation in the most recent year for which figures are available; and what he estimates would have to be the average tariff increase necessary on an across-the-board basis to attain a 10 per cent. to 12 per cent. return on net assets.
§ Dr. J. Dickson MabonThe British Gas Corporation's return on net assets before interest was 9.3 per cent in 1976–77. To have achieved returns of 10 per cent. and 12 per cent. in that year would have required increases of 1.0 per cent. and 3.5 per cent. respectively in revenue from gas sales.
