Intelligent Octopus Go is the UK’s most popular EV tariff
Since we launched the UK’s first EV tariff Octopus Go in 2018, more and more EV drivers have switched to Octopus to charge their car for less.
In a 2025 YouGov Plc survey of 2046 EV owners online, 33% of owners with an EV-specific tariff, charged with Intelligent Octopus Go. More than with any other supplier.
You could save up to 86% vs public charging
A slow or fast charge (<50 kWh) with one of the UK’s public charging points costs an EV driver 51p/kWh on average (last checked 24 September 2025). With Intelligent Octopus Go, you smart charge for only 7p/kWh and save 86%.
1 - 7/51 = 0.86 or 86%
