Energy Bill Calculator

Switch energy with confidence

Take 3 minutes to work out exactly how much gas and electricity you use.

Price comparison sites ask you how much energy you've used in the past year.

If you don't give an accurate answer, you could end up switching to a tariff that costs you more money.

Energy Bill Calculator analyses your last few bills and gives you an exact answer, so that you can switch with confidence.

Currently compatible with:

  • British Gas
  • E.ON
