Understanding your energy bill

Your bill may look like a lot of complicated facts and figures. So to help you know what’s what, it’s all laid out for you below.

Your customer number and bill period

Energy companies give you your own unique customer number to identify you, so when you call them or access your online account, they’ll know it’s you.

The bill period will show how much energy you’ve used since your last bill.

How much do I owe?

Your bill doesn’t just cover the cost of the energy you’ve used. It also includes VAT, government charges for green and social initiatives, plus your energy company’s running costs.

The type of energy tariff you have

This is the name of the energy plan you chose, along with its terms and conditions. Check you’re still happy with your plan by looking up your tariff on your energy provider’s site. You can also compare your tariff with what other energy providers offer.

How much energy have I used?

The amount of energy you’ve used is shown here in kilowatt hours (kWh). That’s the unit of energy that companies like us use to measure your gas and electricity consumption.

Energy bill payment date

This is the day your payment needs to reach your energy provider or, if you pay by Direct Debit, when your payment will come out of your account.

How does your energy bill compare?

Some energy providers will use your bill to offer you cheaper tariffs that might be a better fit for you. It’s a good idea to compare these with your current rates and see if it makes sense to switch. Or, you can compare your current tariff with those offered by other energy companies to see if you’re better off changing supplier.

Take a look at our guide to an average energy bill and see how yours measures up. And if you think you could get a better deal, we can show you how to switch.

Make sure you check the terms of tariffs carefully though, as there may be an exit fee if you choose to leave your current plan and move to another provider.
