We offer a range of tariffs designed to suit different lifestyles and to meet your electricity needs, for lighting and heating your home or office, and everything else for which you require power.

What is a tariff? 
Put simply, a tariff is used to calculate your electricity bill. Each tariff is made up of a standing charge and a charge per unit of electricity used. The Standing Charge is the amount you pay per quarter to be connected to the electricity supply system, regardless of how much electricity you use.

This is similar to your home phone bill; you pay for your connection and for the amount of time you spend on the phone.

Your electricity bill will tell you which tariff you are currently using.

On page 1, you will find the name of your current tariff (such as Domestic Super Economy 12 Tariff) and the relevant Calculation Code can be found on page 2 in the ‘Electricity Billing Calculations’ section under Tariff (such as E12D). For more information take a look at our bill explanation help guide.

Your meter measures your electricity consumption in kilowatt hours (kWh). A kilowatt hour is a ‘unit’ of electricity. Our charges refer to the number of units consumed, for example:

Units Used:                Tariff:             E12 Unit rate:            Total:

100                              E12D              8.57p                           £8.57

Please note, you may be using multiple separate tariffs depending on your electricity usage.
