Intelligent Octopus Go is Octopus Energy’s flagship electric vehicle (EV) tariff, offering ultra-low overnight rates and automatic smart charging. It’s designed to optimise your EV charging schedule, saving you money while you sleep — and it works for the rest of your home’s electricity use too during off-peak hours.
✅ 7p per kWh from 23:30 to 05:30 — for your EV and the rest of your home
✅ Smart charging that automatically schedules your EV to charge at the cheapest times
✅ Day rate is region-dependent, usually in line with the Flexible Octopus tariff
✅ Requires a compatible EV or charger (Ohme, Wallbox, or certain EV brands)
✅ No need to set charge times manually — just plug in and set your desired battery level
✅ 100% renewable electricity as standard
You’ll need a SMETS2 smart meter and an eligible vehicle or charger. You may need to start on the Flexible Octopus tariff while your setup is checked.
🔌 Intelligent Octopus Go is ideal for EV owners who want hands-off charging and the best overnight rates in the market. If your setup qualifies, it’s a no-brainer.
💡 Tip: You can still use other appliances during the 7p night rate period — perfect for running dishwashers, washing machines, or home batteries at the lowest cost.
Intelligent Octopus Go works with a wide range of electric vehicles and smart chargers. If your setup is compatible, you can unlock automated charging and the lowest overnight rates Octopus offers.
Compatible EVs
Intelligent Octopus Go supports many popular electric car brands, including:
Compatible EV Chargers
✅ Ohme and Wallbox smart chargers are fully supported — regardless of which EV you drive.
🛠️ Not on the list yet? No problem. Octopus is constantly expanding compatibility. If your vehicle or charger isn’t eligible right now, they’ll add you to a waiting list and notify you when you can join.
💬 Tip: Even if your EV isn’t supported directly, a compatible charger like Ohme can still get you onto the tariff — it’s worth checking!
As of April 2025, Intelligent Octopus Go is now available as a 12-month fixed tariff. This means you can lock in the low 7p overnight rate and your day rate for an entire year — offering even more peace of mind.
Surprisingly, the fixed version is priced slightly cheaper than the standard Intelligent Octopus Go, which is typically variable and linked to the Flexible Octopus day rate. So if you’re eligible and like the idea of price certainty, the fixed option could be an even smarter switch.
Octopus Go is a popular EV tariff built for predictable, overnight charging. With a fixed low-rate window each night, it’s ideal if you prefer to manually schedule your charging and want a straightforward way to save.
✅ 8.5p per kWh off-peak rate from 00:30 to 05:30 every night
✅ Fixed off-peak window — easy to plan around
✅ Use the cheaper rate for other household appliances too
✅ Daytime rates vary by region, similar to the Flexible Octopus tariff
✅ No smart charger or car integration required — you’re in control
✅ 100% renewable electricity included as standard
You’ll need to manually schedule your EV to charge during the off-peak hours using your vehicle’s app or charger settings.
🔌 Octopus Go is perfect for EV drivers who like to set their own charge schedules and want predictable, low-cost overnight electricity.
💡 Tip: Washing machines, dishwashers, or even battery storage systems can also benefit from the off-peak window — not just your EV.
