From 2026-07-01 Ofgem's headline uses its revised Typical Domestic Consumption Values: 2,500 kWh electricity and 9,500 kWh gas on Direct Debit.
Capped rates multiplied by this consumption give a total close to Ofgem's published whole-pound headline (for example £1,723.61 calculated against £1,723 published for October to December 2026).
Before then Ofgem used 2,700 kWh electricity and 11,500 kWh gas. That older basis is kept only for like-for-like comparison with older figures.

Awaiting verified data. The table appears here once the current record loads.

It describes a typical household, not your own usage.
Figures quoted on the older basis are higher for the same rates, so the two must not be compared directly.

Current Ofgem energy price cap — The headline annual figure and capped unit rates and standing charges for a typical Direct Debit household.
Ofgem Typical Domestic Consumption Values — The standard medium-household gas and electricity consumption figures used as calculator defaults.
