Degree day data

Free data

You can view the data at our Energy Management Register web site. You need to be an EMR member but joining is free of charge if you haven't already signed up.

Paid subscriptions

With our FlexDD service subscribers get self-updating Excel workbooks containing both heating and cooling degree days, to a range of user-selectable base temperatures. Both weekly and monthly figures can be provided and weekly data can be set to end on any day of the week. There is no need to log in to collect data, nor to transcribe information from update emails.

Prices and ordering: subscriptions cost 12 per reported station per year with a 60 fixed charge per order (which applies both to initial setup and subsequent renewals). To minimise renewal costs you can request an initial subscription of any duration from 12 to 60 months.
