* Octopus Intelligent gives you 6 hours at a reduced rate, this is controlled by Octopus at the cheapest hours, you just tell them how much charge you want to add, with Intelligent any electricity used in the allotted hours will be at the reduced rate, not just car charging.
** Octopus Electric Tracker follows the market wholesale rate, the rate displayed is todays live unit rate. This can go both up and down, so you will need to monitor this. You can change on/off the tariff the same day over the phone, so the risk is low as long as you monitor the situation.. Tariff is opening up again from July 1st 2023 – worth getting on the waiting list now if you’re interested.
*** OVO Anytime requires you to have a supported car (e.g. Tesla) OR a smart EV charger and allow them control of it through the API, you will only get electricity used to charge your car at the discount rate.. Whilst listed as 10 hours, this could on occasion extend past that depending on how much charge is needed (if using the “granny” charger for example).

The monthly calculations are based on 4 weeks/28 days
