HC Deb 09 December 1969 vol 793 cc84-5W
100. Mr. Wolrige-Gordon

asked the Minister of Technology by what percentage has coal, gas and electricity appreciated in price since December 1964.

Mr. Alan Williams

Single measures of the overall percentage change in prices may mislead, as increases to individual classes of consumers may differ significantly from any average. The following information, available from the published reports and accounts of the industries concerned, shows how the average values per unit of quantity sold have appreciated:

Percentage increases between 1964–65 and 1968–69
Per cent.
Coal: average colliery proceeds per ton of saleable output. 7
Gas: average revenue per them of gas sold. 4
Electricity: average revenue per unit sold. 15
