Bill rank is not population rank
This calculator uses Ofgem's October – December 2026 unit rates and standing charges. The GB typical is £1,936 for medium use. East Midlands is cheapest at £1,805 (#1 of 14 on bill) while London is largest (#1 of 14 on population) at £1,845 (bill rank #4).
Bill peak is not standing-charge peak
This calculator uses current unit rates and standing charges. Across 24 stored Ofgem quarters, January – March 2023 is typical-bill #1 of 24 at £4,279 (standing rank #16), a different quarter from October – December 2024, standing #1 of 24 at 92.65p/day (typical-bill rank #15). Standing charges and the typical bill do not peak together.
How the stored quarters moved
Exclusive cut of the 24 national Ofgem quarters by change vs the prior quarter. Orthogonal to the bill-vs-standing dual above: direction counts only, not peak ranks.

How this calculator works
According to Ofgem, the default tariff cap for October – December 2026 is £1,936 a year for a typical dual-fuel household on direct debit, using 2,700 kWh of electricity and 11,500 kWh of gas. This calculator starts from Ofgem's published unit rates and standing charges for that period - 26.32p per kWh of electricity and 7.97p per kWh of gas, plus standing charges of 54.83p and 29.68p per day, and applies your region's cap factor and your chosen usage to estimate an annual and monthly bill.
The figure is an estimate for a standard-variable, direct-debit tariff, published by Ofgem and refreshed each quarter; it does not reflect prepayment or standard-credit rates, fixed-deal pricing, or supplier-specific charges. Your inputs are stored only on your own device, and the result link encodes your choices so you can share or revisit your estimate. For the full method and sources, see our methodology.
Every figure on PlainEnergyBills is rendered directly from Ofgem source data, no number is typed in by an editor. Calculator rates are the published Ofgem GB-average unit and standing charges for the named cap period, scaled by each region's live cap factor.
