Welcome to the updated Gas Bill Calculator. We've made a bucket load of changes to the site to help you calculate your gas bills but don't worry, if you have a tiered Gas Tariff or want to use the old version we've put it here.

The new Gas Bill Calculator is much like the old except now you can pick your supplier and gas tariff. You can also factor in standing charges, billing periods but most importantly, the Gas Bill Calculator now takes into account payment methods for supported tariffs.

We've had to change the way the Gas Bill Calculator works as UK Energy Suppliers are being forced to abandon tiered tariffs so soon we'll all be on a fixed tariff with a standing charge.

Many of these figures can be found on your bill.
