How is my energy bill calculated?

This gives you a breakdown of how we have calculated your energy bill. Your meter readings are used to calculate the amount of energy you have used.
Electricity is measured in kilowatt hours but we have to convert gas units into kilowatt hours. Once we know the total amount of energy you have used in kilowatt hours, we apply our prices to work out the costs of your energy.
