Points are interactive: hover, focus or select one for exact values. Shaded band is the cheapest-to-dearest spread within each month; the line is the duration-weighted mean. 4 periods are drawn from part of the calendar rather than all of it: Apr 2025 (21 of 30 days), May 2025 (20 of 31 days), Jun 2025 (1 of 30 days), Aug 2026 (22 of 31 days). A month is partly counted where a version went on or came off sale inside it, and the current month is always still in progress. They are drawn hollow.

Each month shows the version of Intelligent Octopus Go you could actually have signed up to then, so the line follows the tariff through its successive versions rather than any one product code. Older versions carry on publishing rates for months after they stop selling; those are not averaged in, because nobody could buy them. Drawn from the stored daily rollups across every payment method the tariff publishes; where a tariff publishes more than one, the rates above show the direct-debit one and this line sits between them.

Both columns cost the same 2,500 kWh a year on the typical household consumption pattern, on a direct-debit basis — the basis the cap itself is set on. A negative difference means this tariff was cheaper. The cap is a cap on what you can be charged, not a price anyone is billed, so this compares this tariff against the maximum a capped tariff could have charged the same household.

About Intelligent Octopus Go

Smart EV charging that automatically finds the cheapest times. Set it and forget it, and your car will be ready when you need it. You tell the app when you need your car and how much charge you want, the system automatically schedules charging during the cheapest periods, and you wake up to a fully charged car having paid the lowest rates available. Intelligent Octopus Go guarantees 6 hours of cheap electricity but can schedule them flexibly throughout the night, and it may also offer bonus cheap periods when the grid has excess renewable energy.
