“Ohme, BMW, Mini, and Polestar
For some manufacturers, things work a little differently. If you use an Ohme charger or drive a BMW, Mini, or Polestar, the 4-rate tariff still applies, but your experience works a little differently.
If you have an Ohme Charger: You will manage your schedules entirely in the Ohme app, not the Octopus app. When enabled, the Prioritise setting will automatically appear in your Ohme app.
To keep your charging under 6 hours, go to Charging > Prioritise and select Prioritise Savings.
Selecting Prioritise Target (default) means Ohme automatically schedules charging across multiple time slots between plug-in and unplug to reach your battery target, and you will pay peak rates for any extra charging time over 6 hours. (Make sure your Ohme app is updated to latest version and notifications are on so they can warn you!)
If you drive a BMW, Mini, or Polestar: You will set your target battery percentage and departure time in your car’s native app. However, these apps don't have a built-in feature to stop you from exceeding the 6-hour limit.
This makes the Octopus app notifications even more important.
If your settings are going to push you over 6 hours into peak rates, we’ll send you a notification suggesting an alternative target. You’ll then need to open your BMW, Mini or Polestar app and manually lower the target to keep your charging in the cheapest times.

Our data shows that over 80% of EV charging sessions take less than 6 hours. So, instead of spreading the off-peak rate too thin or creating a dozen confusing tariff variations (yes, we’re looking at you, Octopus Go Faster), we’ve tailored Intelligent Octopus Go to work brilliantly for how people actually charge.
We’ve split out your car charging and your home use, creating a dynamic 4-rate system. It sounds complicated, but it boils down to four simple rules:
Your home off-peak: Your house always gets the cheap off-peak rate between 23:30 and 05:30. Reliable, consistent, cheap green electrons every day.
Your car allowance: Your car gets up to 6 hours of off-peak charging per day (measured midday to midday). We might schedule this during your home's off-peak window, or at other times of the day when the grid is greenest.
Your freebie (the bonus home rate): If we schedule your car to charge outside of the 23:30–05:30 window, your home also gets the off-peak rate for that half-hour when it’s within your car allowance.
Your standard rate: The default for your home, outside its off-peak window. If your car charges for more than 6 hours (or you decide to Boost charge), the car rate flips back to this rate (even if it happens at 2:00 AM while your house is still getting the off-peak rate).
