How do you calculate my payments?

In the UK, the result of every gas and electricity meter reading for every property is shared with a regulated third party.

The third party provides us with two approved pieces of information:

  • EAC: the Estimated Annual Consumption of electricity at your chosen property
  • AQ: the Annual Quantity of gas used at your chosen property

We use these figures to calculate how much energy you’re likely to use within the year. Then we work out how much that’s likely to cost, based on the current price of our variable tariff.

We take your account balance, divide the estimated annual cost by 12, and end up with your monthly payment amount.

As our tariff is variable and reflects the true cost of energy if wholesale prices go up, we’ll suggest you increase your payments, and if they go down, we’ll suggest you decrease them.

The best way to make sure you’re paying the right amount is by entering regular meter readings into your account. Find out how to submit a meter reading, or how to read your meter.
