How the comparison works
Custom definitions are saved only in this browser's local storage on this device. They are never sent to this site or to Octopus Energy. Forgetting an account does not clear them; this page has its own clear action.
Without an account connection, one documented synthetic half-hour profile is scaled to your annual kWh. With a connection, pricing can use your browser-held private usage. Every ranked tariff uses the same shared window of seven to 28 complete London days.
Current restricted or conditional products remain visible with their eligibility note. A dual-register tariff remains visible but unranked because one import-consumption stream cannot truthfully infer separate day and night usage.
Limitations
Synthetic results are illustrative: they are not a bill, quote, forecast, switching recommendation, or proof of eligibility. Discounts, export, dispatch, exit fees, billing adjustments, and future prices are excluded.
