§ Mr. Ralph Howellasked the Secretary of State for Energy if he will publish a table showing at current and at constant prices the costs per unit, therm and so on of each of electricity, gas, coal and oil in 1950, 1960 and each year since 1970, for domestic users.
§ Dr. John CunninghamThe requested information is shown in the attached tables.
233WThe records available to this Department for the period concerned are such that strict comparability between the fuels is not possible. The figures for gas relate to financial years, those for electricity are on calendar year basis while the information for oil and solid fuels relate to December in each year.
Average net selling values for electricity and gas are derived from the revenues divided by the quantities sold to domestic consumers. These statistics of unit sales are influenced by changes in patterns and levels of consumption in additon to changes in tariffs. The tabulated data reflect expenditure by consumers and do not take account of varying efficiencies of the appliances or circumstances in which the fuels are used. The constant value statistics are based on the General Index of Retail Prices or the Interim Index of Retail Prices.
