ERRATA: Please note that due to an errata received from our data supplier on the 3rd of July 2017 (see below), TEAM has amended both the data for the yearly heating degree days and the 20-year average heating degree days.

From the source website:

"PLEASE NOTE: Following a review of past reports and the discovery of erroneous results in some regions over recent years, the decision has been taken to change the sources of temperature data and to restate past reports for all regions. In the first instance retrospective corrections have been made spanning ten years. All 20-year average data have been recalculated as part of this process. We apologise for the inconvenience caused."
