Save £100s with Intelligent Octopus Go

With Intelligent Octopus Go you'll save when charging your EV and on the energy use of your whole home with

all smart charging at off-peak rates - no matter when

6 hours of cheap, green energy for your whole home every night

How much you'll save depends on how often you smart charge your EV and how much of your home's electricity you use during off-peak hours.

For example, considering the standard Octopus fixed tariff available in March 2026, an EV owner driving 7,000 miles/year could save £417 by switching to Intelligent Octopus Go.

That's based on:

2700kWh/year of energy usage for a typical 2-3 bedroom home
0.306 kWh/mile (last checked March 2026) for a typical EV
The EV is always smart charged at home for a maximum of 6 hours/day
13.98% of energy used during off-peak hours. Based on the consumption behaviour of the typical Octopus customer

A comparison between Intelligent Octopus Go & Octopus Fixed

Answer a couple of questions about your EV and home and we'll give you an estimate of how much you could save with the Intelligent Octopus Go savings calculator.

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 their latest State of the market report, Ofgem shared that 502k domestic customers were on a Smart Time of Use EV tariff in January 2024. More than half were with Octopus, and the majority of them charged with Intelligent Octopus Go.

You could save up to 85% vs public charging

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 March 2026). With Intelligent Octopus Go, you smart charge for only 8p/kWh and save 85%.

1 - 8/54 = 0.85 or 85%

You’ll save up to 67% when smart charging with Intelligent Octopus Go compared to a standard tariff

With Intelligent Octopus Go you can smart charge for only 8p/kWh. The average rate of a standard variable tariff, based on the April 2026 Ofgem energy price cap, is 24.67p/kWh.

1- 8/24.67 = 0.67 or 67%
