Mr. Dobson

To ask the Secretary of State for Energy pursuant to his answer of 25 June,Official Report, column 436, if he will give the formula used to adjust energy consumption according to the weather.

Mr. Wakeham

The formula used to adjust energy consumption according to the weather applies to the space heating of a building and is: Adjusted consumption=DDO/DD x Total space heating consumption DDO is the 20-year average of degree days, and DD is the number of degree days for the current year. This information is prepared on a regional basis by the Meteorological Office. DDO and DD should refer to the same region.
