Is there an Octopus Go Gas Tariff?

No. Octopus Go is simply for your electricity but you can pick a standard Octopus gas Tariff to sit alongside your Go electricity tariff.

Sounds too good to be true. What’s the catch in switching to Octopus Go?

There’s isn’t a hidden catch in switching to Octopus Go. You’ll just need a smart meter that sends half-hourly readings to Octopus. The smart meter tracks when you use your energy so that the discount can be applied. (You’re not locked into this tariff. You can switch to another tariff at any time or even leave Octopus Energy with no penalties)

How does Octopus Go faster work?

The Octopus Go Faster tariff is ideal for EV drivers who want to pick when their energy rate is discounted.  The standard Go tariff, 12.30-4.30am is ideal for overnight charging but what if you work night shifts or can’t charge your EV during these times? This is where Octopus Go Faster fits in. You can select the start time and duration of your Octopus Go discount. You can start from 20.30 to 03.30 and the duration can be 3, 4 or 5 hours in length.

Octopus Go Faster is by invite only for existing Octopus Energy customers. Once you have switched to Octopus you can email [email protected] and ask if you can move over to one of these tariffs. I know spaces are limited but the switch is a really straightforward process. 

Option 1. Take a 3-hour Go period at 4.5p/kWh and select a start time of 20.30, 21.30, 22.30, 23.30, 00.30, 01.30, 02.30 or 03.30

Option 2. Take a 4-hour Go period at 5.0p/kWh and select a start time of 20.30, 21.30, 22.30, 23.30, 00.30, 01.30 or 02.30

Option 3. Take a 5-hour Go period at 5.5p/kWh and select a start time of 20.30, 21.30, 22.30, 23.30, 00.30 or 01.30

The unit price will change slightly depending on your geographical location. The quote is from 13th May 2021.

Option 2 - 4 hours discounted.5p per kWh

How does the Octopus Go Faster differ from Octopus Go Tariff?

The rate outside the discounted period stays the same for both Octopus Go and Go faster. One isn’t cheaper than the other it’s just the discounted period and price that varies.

There are altogether 21 variations on the Octopus Go Faster tariff and the standard tariff also varies per region too.

The names of the tariffs are based on the time and the during. So for example, if you wanted a 3-hour charge starting at 20.30 the tariff would be called GO-3H-20.30. If you want a 4-hour charge starting at 21.30 the tariff would be called GO-4H-21.30 and so on.

How do you switch to the Octopus Go tariff?

As a new customer, you’ll simply have to switch to Octopus Energy and select an interim tariff before making your switch to Octopus Go. As a new customer, you have to sign up for a nonsmart tariff when you switch. It’s then a case of moving from your interim tariff to your chosen smart tariff, such as Octopus Go.

  1. Switch to Octopus Energy. (This usually takes around 17 days)
  2. Octopus must be satisfied that they are receiving half-hourly readings from your smart meter. (This usually happens with 14 days but could take longer.
  3. You can then switch to Octopus Go.

You can check on your Octopus Energy dashboard to see if half-hourly readings are being received.

If you haven’t got a smart meter it’s a case of switching, requesting a smart meter, and waiting for an installation date to become available in your area. You’ll need a Secure SMETS1 (Secure is a brand name and it’s written on the front of the meter) or a SMETS2 smart meter to switch to any of the Octopus smart tariffs.

There’s no getting around it switching to Octopus Go does take a little more time than a standard tariff.

Here’s what Octopus has to say.

“Octopus Go is a beta product. If you’re OK that some things may not work the first time, that installations and processes may take longer than we’d like, and that on occasion data issues with smart meters can take significant time to fix or prevent things working at all, but that you’d like to work with us to make world-changing energy tariffs a reality… You will always be able to switch to one of our fairly priced standard tariffs at any time.”


Octopus Energy has fantastic customer service and some great tariffs to choose from while you wait to move over to Octopus Go! 🚘

Quick Tips

If you have been with another supplier and you’re not sure if your SMETS1 smart meter will work Octopus look for the word “Secure”. It should be written on the front of your smart meter.  Secure is a tradename.  Secure also supplied meters to Utilita, Shell, OVO, E.ON, and Bristol Energy.  Any other brand of SMETS1 smart meter will not retain its smart functionality if you switch to Octopus.

Although Octopus Go is advertised on the Octopus Energy website you will struggle to find information on the Go Faster Tariff. This is because it’s been limited to invitation-only. If you switch to your interim tariff first you can email [email protected] or [email protected]   Octopus Go Faster tariff is being tested so it isn’t being advertised on their website. You will find lots of chat about it on EV forums. Octopus never stops thinking of ways to save customers money! Ready to switch to Octopus?

My experience getting a smart meter with Octopus Energy

There is a waiting list and I have to be honest I did wait a while for mine! Plus after the meter was installed I got slightly frustrated that it didn’t go online straight away. After install, the engineer couldn’t get it to connect. It was resolved quickly by Octopus but it did take a few weeks for the meter readings to be switched over. The engineer submits the old readings and they have to inturn be updated in the central system along with my new meter number. So even after having the meter installed there is a further wait. Octopus suggests 14 days but in my experience, it was slightly longer. So you have to be prepared for a wait!

Once your meter is sending half-hourly readings your reading to be switched over to the Octopus Go tariff!

If you are a new Octopus Energy customer you can join Octopus HERE⟵ and you will get £50 credit. You can then request a smart meter whilst on an interim tariff before requesting the switch to the Octopus Go tor Go faster tariff.  Just remember there will be a wait!

I would be delighted if you used my code to switch to Octopus as I get £50 too! So a massive thank you if you use my link! Click HERE⟵ 🥳❤︎

Octopus Go review – Compare Octopus Go v Octopus Agile. 

 Compare Octopus tariffs for an EV. 

Personally, I feel it all comes down to how much you want to think about charging your car and using energy.  Octopus Go doesn’t really require that much thought. It’s a plug-and-go solution BUT I am quite sure you can save a little more money on the Agile tariff.

This app allows you to compare Octopus Energy tariffs to find out which tariff is best for you based on your own energy consumption. (find this in the app store here)

“What a great app. Many Octopus Energy customers want to compare energy tariffs, most commonly Agile against Go. This nails it, easy to set up and use. Clear outputs and summaries.”

UPDATE 18/05/2021 At the moment I would be inclined to go for Octopus Go rather than Octopus Agile. If you are on the fence between the two tariffs just take a look at tomorrow’s average cost per kWh. You can read my full review HERE.

This is a quote for Octopus Go Tariff 18th May 2021. It may vary depending on your geographical location in the UK.


If you decide not to switch directly to Octopus Energy but use USwitch comparison website please ignore this chart they are using!!! The different electric cars are NOT more or less expensive to charge! It’s just the battery sizes are different!!!! They all cost the same per kWh!🤦‍♀️

Tip: Octopus Energy EV customers can get a big discount on the Ohme Car charger which works well with the Octopus smart tariffs. Instead of £400 customers pay currently £199. You can also get an Ohme wall discounted with a government grant.

UPDATE: Tesla owners no longer need the Ohme cable. Tesla drivers just need the updated app!! All you need is a standard charging cable and the app. This is possible because the Tesla API, which lets your phone communicate with your car, can stop and start the charging.  The app simply automates the charging when energy is the cheapest/greenest. How cool is that!

How does the Ohme charger work with your Octopus Tariff?

Before opting for the Octopus GO tariff I would suggest you weigh up if you could save even more money by getting creative with the Octopus Agile tariff. This takes a little more creativity and organisation in the home but you could save money on your car charing as well as home appliances. You can always switch tariffs eg Agile in the spring, summer, and Autumn, and then Go in the winter when there is very little solar activity. It is really easy to switch between tariffs. It just depends on how much time you want to spend thinking about it to save money!!! This is a great article by Ofgem on half-hourly and Net-Zero.

Octopus Energy vehicle-to-grid project. (South East)

If you live within the pink area in the South East you could apply to take part in the powerloop project.  Vehicle-to-grid is a new way of thinking about home energy management with the ability to have a constant energy cycle: allowing energy to flow from the house to the car battery, and from the car battery to the grid.

By using Powerloop you are helping to unlock the potential of stored renewable energy in your car battery and feed it back to the grid during times of peak demand, between 4-7 pm. This is groundbreaking in how we relate to energy at home and make use of excess renewable energy.

I don’t live in this area but I love this idea.  I watched an interview and there’s no need to worry about needing to recharge the battery if you suddenly have to use the car for a journey. As I understand it you can set a cap on the amount of energy that is taken from the vehicle for use on the grid.
