Typical Domestic Consumption Values

Typical Domestic Consumption Values (TDCVs) are industry standard values for the annual gas and electricity usage of a typical domestic consumer. You’ll find them in energy suppliers’ communications, on their websites and on price comparison sites where they are used to calculate the cost of a typical energy bill.

Below you can view the current 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 their actual consumption where possible.

How are TDCVs calculated?

TDCVs are calculated based on data from the two most recent years available. So the figure is as representative as possible for the average customer, we use median consumption values for those years.

On 1 August 2017, we published our decision on revised TDCVs, which will take effect on 1 October 2017. Those revised TDCVs are shown in the table below.

Typical Domestic Consumption Values published 2017

  kWh TDCVs
Gas Low 8,000
Medium 12,000
High 17,000
Electricity: Profile Class 1 Low 1,900
Medium 3,100
High 4,600
Electricity: Profile Class 2 Low 2,500
Medium 4,200
High 7,100

Economy 7 peak / off-peak split

The average day / night split is used to calculate the typical bill for an Economy 7 customer, which can be used on price comparison websites. This allows consumers to estimate their annual bill when they do not know their actual consumption pattern. We provide more information in our decision letter on how consumption patterns vary between customers depending on, for example, their meter type.
