Save £100s with Intelligent Octopus Go
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.
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 energy prices in July 2025, an EV owner driving 7,000 miles/year could save £401 by switching to Intelligent Octopus Go.
That’s based on:
- 2700kWh/year of energy usage for a typical 2-3 bedroom home
- 0.302 kWh/mile (last checked 01.07.2025) for a typical EV
- Flexible Octopus rates
- The EV is always charged at home
- 13.98% of energy used during off-peak hours. Based on the consumption behaviour of the typical Octopus customer
Most EV drivers could save by switching to Intelligent Octopus
Between 10th – 14th October 2024, YouGov Plc surveyed a sample of 2009 EV owners online. 58% of EV owners not supplied by Octopus use a standard tariff to charge their EV and 33% have solar and/or battery storage.
Based on their charging behaviour between October 2023 and September 2024, the majority of Intelligent Octopus Go customers (55%) drove at least 6,475 miles. With a similar annual mileage and electricity prices in January 2025, they’d save £371 on their energy bills with Intelligent Octopus Go compared to a standard tariff like Flexible Octopus. The top 20% drove 12,236 miles or more and would save £697.
Intelligent Octopus Go can be combined with Outgoing Octopus to export energy back to the grid. Some homes with solar and battery storage and low annual mileage might save more with Intelligent Octopus Flux.

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.
Between 10th – 14th October 2024, YouGov Plc surveyed a sample of 2009 EV owners online. 39% of owners with an EV-specific tariff, charged with Intelligent Octopus Go. More than with any other supplier.
You’ll save 87% vs public charging
A slow or fast charge (<50 kWh) with one of the UK’s public charging points costs an EV driver 52p/kWh on average (last checked 01.07.2025). With Intelligent Octopus Go, you smart charge for only 7p/kWh and save 87%.
1 – 7/52 = 0.87 or 87%
You’ll save 70% smart charging with Intelligent Octopus Go compared to a standard tariff
With Intelligent Octopus Go you can smart charge for only 7p/kWh. The average rate of a standard variable tariff, based on the July 2025 Ofgem energy price cap, is 25.73p/kWh.
