Typical Domestic Consumption Values (TDCVs) are industry standard values for the annual domestic gas and electricity used by a typical consumer. You’ll find them in energy suppliers’ communications, on their website and on price comparison sites where they are used to calculate the cost of a typical energy bill.
Below you can view the current representative typical domestic consumption values. Consumers can use these to more easily compare between supplier tariffs on a like-for-like basis. They provide a useful starting point, but it’s still important consumers find out what’s right for them by using more personalised information.
How are TDCVs calculated?
TDCVs are calculated based on data from the two most recent years available. So the figure represents the greatest number of customers, we use median consumption values for those years.
On 28 May 2015, we published our decision on revised TDCVs, which took effect on 1 September 2015. Those revised TDCVs are shown in the table below.
On 22 June 2017, we published our open letter to revise the TDCVs, with a view to publishing the decision letter in late July 2017.
