The easiest and cheapest way to home charge your EV

Put us in charge

Use the IO app to set how much you'd like to charge up, and by what time – and we'll handle the rest. Intelligent Octopus pairs with your EV or charger to optimise your charging to the very greenest times, and always on your super cheap rate.

Cheap power for hours

Get six hours of cheap, green energy from 11.30 pm to 5.30 am every night, for home and charging. You can save up to £200 a year vs. Octopus Go.

Charging at your fingertips

With our handy, hassle-free app, you're in control. Tell us when you need your car charged, and by how much. Track your energy spend at a glance, broken down by charging and home use.

Excellent Octopus!

The tariff gives us at least 5 hours of electricity over night at 7.5p/kWh and when combined with solar generation in the day we are very pleased with the average daily pence per kWh. The website and app make it all easy to monitor and manage.

Hang tight while we get your smart meter set up

Intelligent Octopus only works in homes with a smart meter that sends us half hourly readings. That's second generation SMETS2 meters and some types of SMETS1 meters. Not sure what type you have?

If you don't already have one, we can arrange to install a SMETS2 smart meter at no extra cost. These are suitable for most homes (with some exceptions). Everything you need to know about smart meters with Octopus.

It typically takes us 14 days to connect to your smart meter. We'll let you know once we're ready to roll.


Get ready to charge

Once you're set up on the app and ready to go, your tariff will change to IO and you'll be ready for your first smart charge!
