Points are interactive: hover, focus or select one for exact values. The line is the plain average of the regional monthly means — all 14 regions, in every month — and the shaded band runs from the cheapest of those regions to the dearest in that month. So the band is the spread BETWEEN regions, not the spread within a month — a regional page’s chart shows the latter. Nobody pays the line; it describes the country rather than a bill. 2 periods are drawn from part of the calendar rather than all of it: Oct 2022 (18 of 31 days), Sept 2026 (12 of 30 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.

About Octopus Go

Cheap overnight electricity for EV charging. Every night from 00:30 to 05:30 you get access to the off-peak rate, and outside that five-hour window you pay the standard peak rate. Charge your electric vehicle overnight and wake up to a full battery: a 7kW charger can add 100+ miles of range during the off-peak window. Unlike Agile, Go rates are fixed and predictable, so you always know exactly what you'll pay, making budgeting easier. If you can't shift much usage to the overnight window, or if you prefer more flexibility, Octopus Agile or Intelligent Go may suit you better.

Good to know

Questions, answered

What is Octopus Go?
Octopus Go is an electricity tariff designed for electric vehicle owners. It offers a much cheaper rate during off-peak hours between 00:30 and 05:30, making it ideal for overnight EV charging.
What are the Octopus Go off-peak hours?
The Octopus Go off-peak period runs from 00:30 to 05:30 every night. During this 5-hour window, you pay the cheap rate. Outside these hours, you pay the standard peak rate.
Do I need an electric vehicle for Octopus Go?
While Octopus Go is designed for EV owners, you don't technically need an EV to be on the tariff. However, you'll benefit most if you can shift significant electricity usage to the 00:30-05:30 window.
How does Octopus Go compare to Agile?
Octopus Go offers predictable, fixed off-peak rates every night, while Agile prices vary every 30 minutes. Go is better if you want certainty and can charge overnight. Agile may save more if you can be flexible with timing.
Do I need a smart meter for Octopus Go?
Yes, Octopus Go requires a smart meter to track when you use electricity and apply the correct rates for peak and off-peak periods.
Can I charge my EV fully during the off-peak window?
Most EVs can add 100-150 miles of range during the 5-hour off-peak window using a 7kW home charger. This is typically enough for daily driving needs.
