Octopus Tariff Comparisons Changing Tariff At some point in November, we were experiencing consistently higher prices on Octopus Agile, and I decided to switch tariffs for the rest of the winter at least. Octopus have an “Intelligent Octopus” tariff that charges 7.5p kWh between 11:30pm and 6:00am each day, and around 30p kWh the rest of the time. This tariff is not supported by our V2H charger yet - they specifically say it’s not supported.
