General
More information on the methods used to compile figures and data, is included in the annual Digest of United Kingdom energy statistics (DUKES)
Notes to tables
Figures for the latest periods and the corresponding averages, or totals, are provisional, and regularly revised.
The figures have not been adjusted to reflect temperature or seasonal factors, except where noted.
Totals may not always tally, due to the rounding of sums.
Percentage changes relate to the corresponding period a year ago. We calculate them from un-rounded figures but show them only as (+) or (-) when the percentage change is very large.
Monthly figures relate to four-week periods, except in the gas and petroleum sections where they relate to calendar months. Quarterly figures relate to thirteen-week periods, except in the gas and petroleum sections where they relate to calendar quarters.
All figures relate to the United Kingdom, unless we indicate otherwise.

Conversions
- 1 tonne of UK crude oil = 7.55 barrels
- 1 tonne = 1,000 kilograms
- 1 gallon (UK) = 4.54609 litres
- 1 kilowatt (KW) = 1,000 watts
- 1 megawatt (MW) = 1,000 kilowatts
- 1 gigawatt (GW) = 1,000 megawatts
- 1 terawatt (TW) = 1,000 gigawatts
All conversion of fuels, from original units to units of energy, is based on the gross calorific value of the fuel. We provide more information on conversion factors and calorific values in annex A of DUKES.
