Octopus Go Tariff Review 2025:
Is It Still Worth It for EV Owners?
Yes — but it depends on your setup.
Octopus Go remains a reliable smart electricity tariff offering guaranteed cheap overnight charging, which is perfect for EV drivers.
🕒 Off-peak rate: 8.5p per kWh (12:30 am to 5:30 am)
💡 Day rate: 28.10p per kWh (for the other 19 hours)
📉 Standing charge: 49.87p per day (South Wales example)
✅ 12-month fixed tariff ideal for predictable, low-cost EV charging.
But with Intelligent Octopus Go now the most popular EV tariff in the UK, is the original Go still worth it? Let’s break it down.
Written by Sarah Chambers
My first EV tariff was Octopus Go.
When I first bought my Electric Vehicle in 2022, Octopus Go was the go-to Octopus tariff for EV drivers.
I would charge my Tesla overnight on the 4 hours of discounted electricty. It was and still is a cheap and easy way to reduce your energy bill while charging your Electric Vehicle at home.
On Octopus Go, you’ll pay 8.5p per kWh between 12.30 am and 5.30 am. (It has increased to 5 hours.)
There’s nothing complicated about this EV tariff. You just set your charge for the off-peak window, and away you go.
You’ll can schedule your EV charging between 12.30 am and 5.30 am using;
- The scheduling function on your EV.
- An Electric Vehicle smart charger or cable.
- Automated charging using Home Assistant. (For the geeks amongst you.)
⭐ Octopus Go Benefits
✅ Reduces your EV charging cost dramatically
✅ Lowers your overall household energy bill
✅ Helps reduce your carbon footprint
✅ Supports smarter energy use with simple scheduling 🌍
When I was on Go, I got into the habit of running the dishwasher, washing machine, and heating hot water during the cheap window. Those off-peak hours do make a difference to your overall energy bill!
How much does Octopus Go cost?
Octopus Go April 2025 v1 Fixed Tariff is 8.5p per kWh off-peak with a daytime rate of 28.10p per kWh. The daily standing charging has gone up 49.87p. The Octopus Go rate is now a 12-month fixed-rate tariff. It is an amazing deal if you want electric off-peak for charging!! (Prices may vary slightly in different geographical locations)
| Octopus Go Tariff From 01/04/25 | Energy Price |

This is me. I can be found on social media as Sarah_Go_Green and I have been an Octopus customer for 7 years. I’m featured on the Octopus website and their YouTube channel as a solar customer. I’ve been on the BBC news, published in the Telegraph for owning part of a wind turbine.
Recently I’ve been in Bloomberg simply for being an energy geek. I love renewable energy and make it my mission to reduce my family’s home energy bills while improving our carbon footprint. I’ve got around 7,000 followers across X and TikTok where I talk about electrifying my home and reducing my Octopus energy bill. I can help you too!
I’ve been exposed to many fantastic topics since switching to Octopus and now own a Tesla Model Y called Dennis, MyEnergi Zappi, a 13.5 kW GivEnergy battery and 15 solar panels.
I love to fiddle with apps and monitor my home energy use throughout the day. I am forever comparing Octopus tariffs and share my home usage daily on X, formally Twitter.
🤖 Why I Switched to Intelligent Octopus Go
Since April 2025, Intelligent Octopus Go is now available as a 12-month fixed tariff, which is great news for those who want the benefits of smart charging plus price stability. Before, Intelligent Go was only variable, but now you can lock in the 7p/kWh rate and your day rate, too. Ideal if you like predictable bills but still want those extra off-peak hours!
When I got early access to Intelligent Octopus Go, I jumped ship from Octopus Go, and honestly, it felt like unlocking a cheat code.
📆 Just last night (6th May 2025) , I got 13 hours of off-peak electricity!
I got home and Dennis (my trusty Tesla Model Y, yes, he has a name!) was practically empty; in fact, we were on single digits. I asked for it to be at 80% by 11 am, my off-peak charging started at 10 pm and kept going right through till morning. Perfect! Dennis woke up fully charged, ready to take on another day of school runs, errands, and zipping around town without guzzling petrol. Plus, all my kids’ beds are stripped and I have suddenly become a laundry goddess trying to make the most of that 7p per kWh arte.
This wasn’t even possible a couple of years ago. Back in 2022, Intelligent Go was a new idea. A lot of people weren’t keen on giving up control, and compatibility was a major issue. Fast-forward to now, and it’s changed everything.
📉 Octopus Intelligent Go Snapshot:
- Off-peak rate: 7.0p per kWh
- Minimum off-peak time: 6 hours — but I’ve had up to 13 hours!
- Octopus chooses when your car and home use the cheap stuff
- Compatible with more EVs and chargers than ever before
And yes, you can run your home on that off-peak electricity too.
⚡ Why Stick with Octopus Go?
🆕 The Octopus Intelligent Drive Pack sounds great, similar to unlimited data for your phone, but for EV charging. Octopus Intelligent Drive Pack bolts onto your
existing Octopus Fixed or Flexible tariff, so unlike Octopus Go or Intelligent Go, there’s no increase in your day rate. It takes the worry out of big charging bills, especially if you’re new to electric cars. But here’s the catch: it’s only for your EV, not your home. That means you can’t use the cheaper overnight rates to run your washing machine or charge a home battery.
It also only works with compatible EVs or chargers, so not everyone can use it. And unless you’re doing serious mileage, I would guesstimate around 20,000 miles a year or more, it probably won’t save you more than Octopus Go or Intelligent Go, which give your whole house access to cheaper electricity overnight.
If your EV or charger isn’t compatible with Intelligent Octopus Go or Intellifent Drive Pack, don’t worry, Octopus Go still has your back.
You get:
- A guaranteed 5 hours of cheap electricity every night (no surprises)
- The same day rate and standing charge as Intelligent Go
- Full control over your charging schedule

Don’t Miss the Octopus EV Tariff ‘3 for 2’ Moment
I met someone just the other day — they were collecting their wife’s brand-new EV this Friday. When I asked if they had an EV tariff set up at home, they shrugged. “She just does short trips, I am not really bothered,” they said.
And that’s the thing. I meet so many people who buy an electric car and don’t even think about switching to an EV tariff.
But here’s the truth: buying an EV gives you access to the energy deals that can make your whole household cheaper to run not just the car.
Yes, you’re already saving at the pump. But if you can shift even some of your energy use, like running your dishwasher or washing machine overnight, you’re not just avoiding petrol costs, you’re actively lowering your average unit rate for electricity across the board.
I’ve got three kids. I can’t load shift everything. But even with a higher day rate, my overall home electricity cost dropped after I got Dennis (my Tesla). That’s because I made some changes and timed white goods like my washing machine and dishwasher to come on at night.
Why miss out? It’s like going to the supermarket and ignoring a 3 for 2 offer because you only went in for two. You’d run back, wouldn’t you?
If you’re new to Electric Vehicles and haven’t sorted your home tariff yet, please take a look at Octopus Go or Intelligent Go tariffs. Your wallet will thank you!!
- Join Octopus Energy (you can start on a Flexible or Fixed tariff and get £50 credit using my link.)
- Install a compatible smart meter (if you haven’t got one)
- Request a switch to Go or Intelligent Go once your meter is sending half-hourly readings
📣 Final thought? If you’ve got a smart meter and an EV, there’s no excuse to be paying full price to charge at home. Whether it’s Go or Intelligent Go, just pick the one that fits your setup and start saving.

Compare Octopus tariffs for an EV.
While Octopus Go offers simple, low-cost overnight charging, there are two other smart EV options, plus Agile, worth knowing about:
-
Intelligent Octopus Go – Like Go, but smarter. Your EV and entire home get at least 6 hours at 7.0p/kWh, with charging times chosen by Octopus to support the grid. Great if you have battery storage or want to run appliances at night.
-
Intelligent Octopus Drive Pack – A £30/month bolt-on that gives unlimited EV charging for one vehicle, added to your existing Octopus fixed or flexible tariff. Octopus controls when your EV charges. This doesn’t include off-peak pricing for the rest of the home, so it’s ideal for high-mileage EV drivers without battery storage, but I think Intelligent Go will remain the most attractive offering for most EV drivers.
-
Octopus Agile – Prices change every 30 minutes based on wholesale rates. Can be very cheap or very high, depending on grid conditions. Best for those who are flexible and want to actively manage their usage.

Octopus Go FAQ’s
How do you switch to the Octopus Go tariff?
As a new customer, you’ll simply have to switch to Octopus Energy and go on their Flexible tariff before making your switch to Octopus Go. As a new customer, you have to sign up for a non-smart tariff when you switch. It’s then a case of moving from your interim tariff to your chosen smart tariff, such as Octopus Go.
- Switch to Octopus Energy. (This usually takes around 5 days)
- Octopus must be satisfied that they are receiving half-hourly readings from your smart meter. (This usually happens within 14 days but could take longer.
- You can then switch to Octopus Go.
- Ready to go share £100 when you switch using my new customer referral link.
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.
How can I tell if I have a SMETS2 smart meter already?
Look out for ‘GUID’ or a Device ID which looks like this: AA-BB-CC-DD-EE-FF-00-GG-ZZ on the front of the meter. If you can see a number like this it is a good indication you have a SMETS2 meter.
There’s no getting around it switching to Octopus Go does take a little more time than a standard tariff.
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. For example, the Octopus Flexible tariff.
Has the Octopus Energy Go tariff decreased in price over the last 6 months?
On the 9th of April 2025, Octopus increased the day rate from 26.27p per kWh to 28.10p per kWh. The off-peak rate remains unchanged at 8.5p per Kwh. (Depending on your geographical location.)
Will I get paid for exporting my solar energy with Octopus Go?
Yes, Octopus Energy Go Outgoing tariff currently pays customers to export electricity to the grid. On Octopus Go you can combine it with all Octopus Outgoing tariffs including Octopus Outgoing fixed which has a 15p per kWh export rate. I’ve created a separate post on Octopus Outgoing tariffs.You will need your MCS Certificate and DNO response which you should find in your installers pack. Email seg@octopus.energy to find out more.
I want to move from Octopus Go to Intelligent Octopus Go, but I have two EVs. Can I charge two EVS on Intelligent Go?
Yes, so you have two options.
- Connect your home charger to Octopus so that either vehicle can use it.
- Connect one vehicle to Octopus Intelligent Go and just toggle off the smart charging in the Octopus app, and use Intelligent Go the same as you used Octopus Go. You will just need to schedule your charge for the off-peak window of 11.30 pm to 5.30 am.
