Eligibility, billing and comparison notes
Tariff fit and billing
- Standing charges and day rates can matter as much as the cheap window.
- Smart tariffs, including Tracker, need a working smart meter, half-hourly readings and sometimes a compatible EV, charger or heat pump.
- Solar export is a separate choice, so check import and export together if you have panels or a battery.
- Billing depends on Octopus meter data. Charger apps, inverter apps and screenshots are useful evidence, but they are not the billing record.
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.
An electricity-only row does not mean gas must move too. If you want Go or Intelligent Go while keeping gas elsewhere, our separate gas and EV electricity guide explains the supply and quote checks. Compare each fuel's annual cost, standing charge and any exit fee, then confirm that the quote names only the supply you intend to switch.
Leaving a fixed tariff? Check its end date, any exit fee and the proposed switch date alongside these rates. The fixed-tariff ending guide separates the 49-day fee-free window from Octopus's 45-day account-change option.
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.
