More detailed notes on the methodology used to compile the figures and data sources are included in the annual Digest of United Kingdom Energy Statistics (DUKES).
Figures for the latest periods and the corresponding averages (or totals) are provisional and are liable to subsequent revision.
The figures have not been adjusted for temperature or seasonal factors except where noted.
Due to rounding the sum of the constituent items may not equal the totals.
Percentage changes relate to the corresponding period a year ago. They are calculated from unrounded figures but are shown 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 otherwise indicated.
For a full list see Annex B of DUKES.

p provisional.
r revised; where a column or row shows 'r' at the beginning, most, but not necessarily all, of the data have been revised.
e estimated; totals of which the figures form a constituent part are there-
fore partly estimated.
All conversion of fuels from original units to units of energy is carried out on the basis of the gross calorific value of the fuel. More detailed information on conversion factors and calorific values is given in Annex A of the Digest of United Kingdom Energy Statistics.
To convert from the units on the left hand side to the units across the top multiply by the values in the table:
