Only gotcha is that the intelligent doesn't always work! I've had at it 3 times in a row where the schedule had not been obeyed and charged too much, or outside of the plan. A problem with kia, rather then octopus, apparently. It is beta, after all.

But on the other hand, it does offer cheap rates outside of that 6 hour window if it determines you need it.

And the rest of the house also benefits during that time. The more you can shift off peak (dishwasher, washing machine, etc) the better. Octopus reckons I use over 50% of my household consumption in the off peak hours.

I'm on Go, I would switch to Intelligent but neither my car or charger are compatible yet. I shift everything I can to the overnight slot (dishwasher, washing machine, etc).

The other one to keep an eye on is Agile. It can be stupidly cheap, or even negative, at times. But other times it's easy more expensive. I was on it before the prices kept rising a year or so ago, however I think recently it's worthwhile again.

I was on Go for about two and a bit years and it was awesome. Had the car set to start charging at the correct time each night and always worked.

Now I'm on Intelligent for the past month - I have my charger connected to Octopus rather than the car, but it works in a very similar way, except without the need for a schedule. When I plug in I get a notification that tells me the times scheduled for charging and I let the charger handle it.
