How does Intelligent Octopus Go work and how can I join?
Intelligent Octopus Go is the UK's most popular EV tariff. It gives you access to a super low price between 11:30pm - 5:30am for your whole home, plus it smart-charges your car at cheaper and often greener times overnight. Occasionally we'll smart charge your car outside of the off-peak window but don't worry, all smart charging is billed at the off-peak rate.

Save up to 85% vs public charging when you power up at home with Intelligent Octopus Go.
A slow or fast charge (<50 kWh) with one of the UK’s public charging points costs an EV driver 54p/kWh on average (last checked June 2026). With Intelligent Octopus Go, you smart charge from only 7.6p/kWh and could save 85%.
1 - 7.6/54 = 0.85 or 85%
Charge for up to 70% less than average price cap rates.
With Intelligent Octopus Go, you can smart charge eligible cars from only 7.6p/kWh. The average electricity unit rate of a standard variable tariff, based on the October 2026 Ofgem energy price cap for customers paying by direct debit, is 26.32p/kWh. This represents a saving of 71% compared to the average price cap unit rate (1- 7.6/26.32 = 0.71 or 71%).
Please note that savings apply to unit rates only and exclude standing charges. Standard variable rates vary by region, so your actual percentage saving may vary depending on where you live. Check the price cap for your region here.
