Although many people may not realize it, the price that you pay for your energy is made up of two different charges:

  • Standing charge - this is a fixed amount that you are charged each day, regardless of how much gas or electricity you use.
  • Unit rate - this is the price you will pay per unit (kWh) of energy, so it can fluctuate depending on how much energy you use.

The unit that both gas and electricity are measured in is kilowatt hours (kWh). One kWh of gas is approximately equivalent to leaving a small gas hob burner on for an hour. One kWh of electricity is the rough equivalent of running a washing machine for an hour.

How energy bills are calculated

When calculating the price of your bill, energy providers monitor how many kilowatt hours of gas or electricity you have used over a certain period of time, and then multiply this by the price per unit set in your tariff. The number of days the billing period covers is then multiplied by the tariff’s daily standing charge cost.

They then add the two figures together to provide your total bill.
