Intelligent Octopus Go
A long cheap window, scheduled for you · Electricity
Intelligent Octopus Go extends the cheap overnight block and hands scheduling to Octopus, which charges your car whenever the grid is cheapest and bills the cheap rate even if that lands in the middle of the day.
The bit that catches people out
The headline is a long guaranteed cheap window overnight. The part that matters more is that when Octopus schedules a charge outside that window, it still bills the cheap rate for the energy it moved. You tell the app when you need the car ready and how full; it works out the rest.
That requires an integration — a supported car or a supported charger. Without one you get the fixed window and nothing else, which is closer to plain Octopus Go.
How it compares
Against Agile, Intelligent Go trades upside for certainty: you will never catch a negative price, and you will never be caught by a 90p peak either. Against a flat tariff it is a clear win for any household charging a car regularly.
Everything in the house benefits from the cheap window, not just the car — the dishwasher, the washing machine and the immersion heater all bill at the overnight rate if you run them then.
Common questions
How long is the Intelligent Octopus Go cheap window?
The guaranteed overnight window is several hours long, and charging that Octopus schedules outside it is billed at the same cheap rate.
Can I use Intelligent Octopus Go without a supported car?
A supported charger works in place of a supported car. With neither, smart scheduling cannot run and the tariff is much less useful.
Which tariff is cheapest for you? Headline rates cannot answer that. Connect your Octopus account and halfhourly.uk prices your last 28 days of real half-hourly readings against every tariff's real rates, standing charge included.
