Methodology
Guides draw on Ofgem default-tariff-cap series, regional bills, and consumption profiles in the PlainEnergyBills database. Statutory support scheme amounts are not hard-coded, confirm those on gov.uk.
Every figure on PlainEnergyBills is rendered directly from Ofgem source data, no number is typed in by an editor. Guide hub figures (cap level, regional gap) are live from getCurrentCap and getRegionalBillGap. See our editorial standards & corrections policy, the methodology behind these numbers, or report a data error. Data current as of July – September 2026.
