How your bill is worked out
Each fuel is charged in two parts: a unit rate for every kWh you use and a standing charge for every day you're supplied. So a yearly bill is (kWh × unit rate) + (365 × standing charge), for electricity and gas separately. The calculator uses the maximum price cap rates for Direct Debit customers in your region. If you untick the gas box, it leaves out gas and its standing charge, as for an all-electric home.
Your annual kWh figures are on your bill or in your supplier's app, often labelled "annual consumption" or "estimated annual usage". If you can't find them, the defaults are Ofgem's typical (medium) usage: 2,500 kWh of electricity and 9,500 kWh of gas a year.
Typical bill by region
At typical usage, the yearly dual-fuel bill ranges from £1,672 in East Midlands to £1,805 in Merseyside and North Wales, mostly because electricity standing charges differ by region.

Why your real bill may differ
- Payment method. Standard credit (paying on receipt of a bill) costs more than Direct Debit. Prepayment rates are close to Direct Debit.
- Your tariff. Fixed deals and time-of-use tariffs such as Economy 7 or Octopus Go set their own rates. Compare them in our smart tariff comparison and Economy 7 calculator.
- The season. Most gas is used in winter, so monthly Direct Debits are usually spread evenly, and your account builds credit in summer and uses it in winter.
- Future price changes. The cap changes every three months, and the next period starts on 1 January 2027. This calculator uses today's rates for the whole year.
