Mr. Jim Callaghan
asked the Secretary of State for Energy if he will list in the Official Report the increases in price of (a) a unit of electricity and (b) a therm of gas for the years 1977–78, 1978–79 and 1979–80.
Mr. Gray
The table below shows the average annual price increases in pence per KWh for a unit of electricity and in pence per therm for a therm of gas for each of the past three years. The information is based on the average unit value for total sales by the fuel industries in the United Kingdom during the first three months (Q1) of each year. Data for 1980 is provisional.
| Period | Electricity (pence/KWh) | Natural Gas (pence/therm) |
| First quarter 1977 to first quarter 1978 | 0·278 | 1·83 |
| First quarter 1978 to first quarter 1979 | 0·166 | 0·82 |
| First quarter 1979 to first quarter 1980 | 0·488 | 2·50 |
