HC Deb 28 June 1982 vol 26 c229W
Mr. Knox

asked the Secretary of State for Energy what was the price index for domestic electricity on 1 January in each of the past five years, taking the price on 1 January 1970 as 100.

Mr. Mellor

The price of domestic electricity forms a component of the general index of retail prices published by the Department of Employment. Data from this source yield the following index values:

20 January 1970 = 100
Date Index value
17 January 1978 313.9
16 January 1979 338.0
15 January 1980 402.8
13 January 1981 522.7
12 January 1982 549.6

Data that would enable a corresponding index with 1 January 1970 = 100 to be derived are not readily available.
