Reviewed 3 June 2026. Rates are fetched from the Octopus API when you search and include VAT.
Octopus Go, Intelligent Octopus Go, Cosy Octopus and the smart-tariff terms. The quick comparison uses Go's 00:30 to 05:30 window, Intelligent Go's 23:30 to 05:30 whole-home window plus eligible smart slots, and Cosy's three Cosy Hours with the 16:00 to 19:00 peak.
Treat the table as a postcode rate checker, not a full recommendation. Eligibility, smart-meter data, export pairing, standing charges and your actual usage pattern still decide whether the cheapest-looking row is sensible.
The smart-tariff terms still matter after the rate check: missing half-hourly readings can affect billing, and charger, inverter or app data is supporting evidence rather than the final Octopus billing record.
