asked the Secretary of State for Energy what is the average annual domestic electricity bill.

I understand from the Electricity Council that the average bill in 1984–85 for domestic consumers in England and Wales on standard tariffs is estimated to have been £194—6·03p per kilowatt hour. The estimated average bill for those on Economy 7 tariffs was £309 — 3·82p per kilowatt hour. The resulting overall average electricity bill for all domestic consumers was £206—5·37p per kilowatt hour.
