Quality and accuracy

Degree Days Direct Limited makes no specific claims as to the quality and accuracy of its published data. The data are intended for use in routine management assessment only.

The figures are produced independently of any vested interest and have been used for a number of years by the Department of Health, the Carbon Trust, Croner's Energy Management, and other authoritative sources. They are cited in the terms of Ministry of Defence energy service contracts. Degree Days Direct Limited was first appointed as the supplier of free data for publication by the government after demonstrating that three years' worth of its historical figures agreed, within 15 degree days, with data from the Meteorological Office in 95% or more of the reported months.
