Tariff Comparison Rate (TCR)

Ofgem have removed the TCR

From the 23rd June 2017 Ofgem removed the requirement for energy suppliers and energy switching sites to display the Tariff Comparison Rate (TCR) in the Tariff Information Label.


The TCR was introduced by Ofgem - the energy market regulator in 2010 to help people to compare tariffs from different suppliers (comparing apples to apples).

Your TCR was calculated by using the same unit and tariff rates as the tariff on offer but the usage estimate is based on what Ofgem has defined as medium usage (12,500 kWh for gas and 3,100kWh for electricity) and not your individual situation.

Your TCR was calculated by taking the total annual cost for a 'medium user' and divide it by number of units energy used, for example:


Gas TCR

365 (Days in a year) x 21.00p (standing charge p/day) = £76.65
12,500 (Ofgem's definition of a medium user) x 2.70 (unit rate p/kWh) = £337.50
Total annual gas cost = £414.50

TCR = £414.15 (total annual cost) / 12,500 (annual consumption) = 3.31p/kWh.

Electricity TCR

365 (Days in a year) x 21.00p (standing charge p/day) = £76.65
3,100 (Ofgem's definition of a medium user) x 10.50 (unit rate p/kWh) = £325.50
Total annual electricity cost = £402.15

TCR = £402.15 (total annual cost) / 3,100 (annual consumption) = 12.97p/kWh.
