Octopus Go v Octopus Intelligent Octopus Go

July 2024 Price Drop.

Intelligent Octopus Go rates are now even cheaper. From the 1st of July 2024, it’s 7p per kWh v 8.5p per kWh on Octopus Go. The off-peak rate lasts longer at six hours versus five on Go. However, can everyone be a winner on an Octopus EV tariff?

Octopus Energy is in my mind the best electricty supplier when it comes to green tech and electric vehicles. My name is Sarah and I’ve been a very happy Octopus Energy customer for six years. I’ve also been on the ever-popular Intelligent Octopus EV tariff for over two years.

Advantages of Intelligent Octopus Go

Intelligent Octopus Go since the 1st of July 2024;

  • There’s a minimum of six hours of off-peak electricty for your EV charging and home energy needs for 7p per kWh instead of 7.5p per kWh.
  • The day rate has dropped. The premium which was added to the day rate is now minimal. It’s around 1p per kWh over the flexible rate instead of the previous 4p premium. If you don’t have high mileage you can still benefit compared to the Octopus Flexible rate.
  • Pre-scheduled charging by Octopus at the greenest times for the National Grid. (This has remained unchanged.)
  • You are still able to export your solar (if you have any at 15p per kWh on Outgoing Fixed as well as having access to all the other Octopus export tariffs. Whereas on Octopus Go you’ll still be limited to 8p per kWh export on Outgoing Lite.

Disadvantages  of Intelligent Octopus Go,

  • You need either a compatible EV or EV chargers.


@sarah_go_green Both @Octopus Energy EV tariffs became even more attarctive and prices dropped on Octopus Go and Intelligent Octopus Go on 1st July 2024. The day unit rate for electricty on both has dropped and now it makes more sense even in you don’t drive and charge as much. Octopus Go you will now get an extra hour off-peak too!@GivEnergy ♬ original sound – sarah_go_green

What is the difference between Octopus Go and Intelligent Octopus Go since 1st July 2024?

The main difference between the Intelligent Octopus Go and Go tariffs is the Kraken Software that enables smart charging. That’s it in a nutshell. All Octopus Intelligent tariffs let Octopus take control of a device in your home, with Intelligent Octopus Go it’s either your Electric Vehicle charger or your Electric Vehicle Charger.

Octopus wants to make the best use of green technology to enable the grid to become greener and for customers to take advantage of renewable energy when it is abundant. This is how Octopus intends to revolutionise our relationship with electricty.

On the ground floor as consumers, the main differences are;

  • The length of cheaper charging.
  • The off-peak rates per kWh.

Octopus Intelligent Go offers a minimum of six hours of off-peak electricity for charging your EV at home. In comparison, Octopus Go only provides five hours of off-peak electricity at night. Both still allow the off-peak rate to be used for your home energy needs and EV charging.  (The extra one hour was added to Octopus Go on 1st July 2024)

Octopus Go is 8.5p per kWh and Intelligent Octopus Go is 7p per kWh off-peak.

Why has Octopus Go been given five hours instead of six hours off-peak since 1st July 2024?

Competiton! That’s why Octopus Energy, in my view, added the extra hour of off-peak electricty to the overnight rate on Octopus Go on the 1st of July 2024 as well as dropping the off-peak rate.

For Octopus it’s all about the environment and customer service. They have tweaked the Intelligent Octopus Go tariff so much over the last two years that even the most reluctant customers have given up their timers in exchange for smart charging. Why wouldn’t you when you can save so much more on a cheaper EV tariff?

However, other energy suppliers are offering basic set-and-forget EV tariffs that don’t need smart charging and importantly the off-peak slots have been slightly longer than Octopus Go. This is why in my opinion, Octopus increased the off-peak window for Octopus Go.

In an ideal world, Octopus would love everyone to be on an Intelligent tariff where simplicity of use could help consumers save money whilst also balancing the grid but we aren’t there yet.  Bringing Electric Vehicle and EV chargers into the fold so they are compatible with evolving software takes collaboration of will and time. Until then Octopus Go is a good offering for those with a non-compatible EV or EV charger.

Octopus Go and Intelligent Octopus Go unit rate from 1st July 2024.

Electricity on Intelligent Octopus Go is now 69% cheaper than the Octopus Flexible unit rate and Octopus Go is 62% cheaper than the Octopus Flexible unit rate. Whilst the day rate is around 1p higher per kWh for both. The standing charge is the same.

  • Intelligent Octopus Go and Octopus Go day unit rate: 23.59p per kWh
  • Intelligent Octopus Go and Octopus Go daily standing charge: 61.19p
  • Intelligent Octopus Go off-peak unit rate 7p per kWh
  • Octopus Go off-peak unit rate 8.5p per kWh

This is based on rates in South Wales. The unit rate will differ depending on your geographical location.

Octopus Go and Intelligent Octopus Go vs Octopus Agile.

The Octopus Agile is the only Octopus smart tariff that hasn’t had a price change since the 1st of July 2024.  Unlike the Octopus Tracker tariff which had its formula changed on the 1st of July 2024, meaning a price increase.

Octopus Agile isn’t designed for EVs but here is an example of today’s Octopus Agile rates compared to Octopus Go just to add an alternative smart tariff to the mix.

62.19p per day standing charge.62.19p per day standing charge.

Some Octopus customers have decided to ditch EV tariffs and opt instead for Octopus Agile.  This is usually because they have low mileage and have the flexibility to charge at home anytime taking advantage of electricty when it plummets in price.

Octopus Agile offers a fanatically smart way to use electricty at home when it’s the cleanest and greenest. If you work from home or are retired, as an example you can save oodles on your energy bill. Prices change every 30 minutes and if you are home with your EV plugged in you could gran cheap electrons when available.

Tom and Adam who follow me over on X (formally Twitter) have low mileage and only need to charge once a week. This gives them the flexibility to sometimes even wait and get paid to charge their EV, as when there are lots of renewables on the grid occasionally prices go negative. Imagine getting paid to fuel a petrol or diesel car because it’s windy. There would be a traffic jam with people trying to get to the petrol station!
