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 underpin the Tariff Information Label (Label)open key term pop-up, Tariff Comparison Rate (TCR)open key term pop-up, and various analyses and publications.

Below you can view representative typical domestic consumption values for 2015. 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.

Typical Domestic Consumption Values 2015

  kWh TDCVs
Gas Low 8,000
Medium 12,500
High 18,000
Electricity: Profile Class 1 Low 2,000
Medium 3,100
High 4,600
Electricity: Profile Class 2 Low 2,500
Medium 4,300
High 7,200

Tariff Information Label (Label)

This represents the cost of a tariff for a typical consumer. Suppliers use it when advertising their tariffs – much like mortgage and credit card providers do with APR.

It assumes a medium level of energy use, and includes the unit rates, standing charges and discounts that apply to a given tariff. It also includes the value of some extra products and services.

You can use it as a starting point when comparing tariffs, as it combines the costs of a tariff into one simple pence per... more

Tariff Comparison Rate (TCR)

The TCR is a figure that represents the cost of a tariff for a typical consumer. It is intended to work in a similar way to the annual percentage rate (APR), for credit cards, for example. It assumes a medium level of energy usage, and includes the unit rates, standing charges and discounts that apply to a given tariff. It will also include the value of bundled products, where these are capable of being expressed in p/kWh or £/year.

It can be used as a first point of comparison when... more
