Typical Domestic Consumption Values

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.

They also underpin the Tariff Information Label (TIL) and Tariff Comparison Rate (TCR).

Below you can view representative typical domestic consumption values for 2015. The current TDCVs came into force on 1 September 2015. You 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 to find out what’s right for you based on more personalised information.
