Intelligent Octopus Go Review 2026: Costs, Savings and the Catches to Know
Last Updated: July 1, 2026
Intelligent Octopus Go gives EV owners 6 hours of cheap electricity every night (currently advertised at 8p/kWh for smart charging) plus a standard day rate. Octopus claims typical annual savings of £771 versus its standard tariff. You need a compatible EV or home charger to qualify.
Worth it if: your car or charger is on the compatibility list and you are happy letting Octopus handle the charging schedule.
Skip it if: you want full manual control or your setup is not supported.
Intelligent Octopus Go Review: Quick Verdict
Intelligent Octopus Go remains one of the strongest EV tariffs in the UK. The combination of a cheap overnight rate, smart scheduling, and a growing ecosystem of app features makes it genuinely hard to beat for compatible EV owners.
It is not the cheapest option for everyone. Octopus Go (the non-intelligent version) offers similar overnight rates without the smart scheduling if you prefer manual control. Octopus Agile can undercut Intelligent Go if you are willing to track half-hourly prices and shift usage aggressively. And some fixed tariffs from other suppliers occasionally dip below the Intelligent Go day rate.
But none of those alternatives match the set-and-forget convenience of Intelligent Go. You plug the car in, Octopus builds the schedule, and you wake up to a charged car at the cheap rate without having done anything except plug in a cable. That is the real product, not the headline pence-per-kWh figure.
Current Rates (Verified July 2026)
As of this update, Octopus is advertising Intelligent Octopus Go around three core claims:
| Intelligent Octopus Go | Standard Variable Tariff | |
|---|---|---|
| Smart charging rate | 8p/kWh | N/A |
| Cheap hours per night | 6 (typically 23:30 to 05:30) | 0 |
| Day rate | ~25p/kWh (varies by region) | ~25p/kWh (price cap) |
| Standing charge | ~60p/day (varies by region) | ~60p/day |
| Annual EV charging cost (8,000 miles) | ~£160 | ~£500 |
| Typical annual saving vs SVT | £771 (per Octopus) | : |
The 8p rate applies whenever Octopus schedules a smart charge, even if the slot falls partly outside the core 6-hour window. That is an underrated feature. If your car needs a longer charge and Octopus extends the schedule into the early morning, those extra hours still get the cheap rate.
Standard rate electricity during the day sits around 25p/kWh depending on your region, which is roughly in line with the Ofgem price cap. You are not paying a premium on daytime usage to access the cheap overnight rate.
How the Tariff Actually Works Day to Day
The setup is simpler than most people expect. You sign up, connect your compatible car or charger to the Octopus app, and plug in when you get home. Octopus reads your car's battery level, works out how much charge it needs, and builds a schedule that fits inside the cheapest overnight windows.
You can override the schedule any time. The app has a bump charge button that starts charging immediately at the smart rate if you need the car ready sooner. You can also set a target battery percentage and a ready-by time so Octopus knows what you need.
The car does not have to charge every night. If you plug in with 70% and only need 80% for tomorrow, Octopus schedules a short charge. If you plug in at 20% and need a full charge, the schedule stretches. The system adapts to your usage, not the other way round.
My Experience Using Intelligent Octopus Go
I switched to Intelligent Go after buying my Tesla Model 3 in 2025, and I was charging at the overnight rate the next day. The onboarding took about 10 minutes. Octopus ran a test charge to confirm the connection worked, then handed control back to me.
Looking at my bills since switching, my electricity consumption obviously increased because I was now charging a car at home, but my total monthly cost went down. The reduction came from shifting all the car charging and as much other usage (dishwasher, washing machine, immersion heater) into the cheap window alongside the car. That is the real multiplier with this tariff. Once you are on it, every appliance you run during the cheap hours gets the same low rate. It is not just about the car.
I use the Octopus app regularly to check the charging slots it has allocated and to start a bump charge if we have an unexpected journey. The app has improved noticeably over the last year. Earlier versions could be slow to update. The current version shows the live schedule, energy usage breakdown, and tariff comparison data without much friction.
One thing worth knowing from my own experience: the first week feels weird. Handing over charging control to an algorithm takes a small mental adjustment. After that first week, it becomes normal, and going back to manually timing charges feels unnecessary.
What Makes Intelligent Go Different from Regular Go
Octopus also offers a simpler tariff called Octopus Go, which gives you four hours of cheap overnight electricity at a similar rate but without the smart scheduling. Here is the practical difference:
| Intelligent Octopus Go | Octopus Go | |
|---|---|---|
| Cheap hours | 6 (smart schedule) | 4 (fixed 00:30-04:30) |
| Smart scheduling | Yes | No |
| Compatible car required | Yes | No (just an EV) |
| Bump charge | Yes | No |
| Extra slots outside core window | Yes | No |
| Electroverse 8% discount | Yes | No |
If you have a compatible car or charger, Intelligent Go is the better deal. You get more cheap hours, the system adapts to your battery level, and the Electroverse public charging discount is a genuine extra worth having if you use public chargers.
If your car is not on the compatibility list or you prefer to set a timer manually, regular Go still works and you will still get a cheap overnight rate. You just get fewer cheap hours and no smart features.
Compatible Cars and Chargers
Compatibility is the gatekeeper for this tariff. If your car or charger is not supported, you cannot sign up for Intelligent Go (you can still get regular Go).
Octopus maintains a live compatibility list that changes as new models are added. As of mid-2026, supported cars include most Teslas (Model 3, Model Y, Model S, Model X), many Volkswagen ID models, Audi e-trons, Skoda Enyaqs, Cupra Borns, and a growing list from other manufacturers.
Supported chargers include the Ohme Home Pro, Ohme ePod, Wallbox Pulsar, Indra Smart Pro, and several other models. The charger route is useful if your car is not natively supported but your wall box is.
Check the live compatibility checker on Octopus before signing up. Do not assume your car or charger will work just because it is a modern EV. A few popular models still are not supported, and compatibility can change as Octopus adds integrations.
What Catches People Out
Compatibility surprises. The most common frustration is signing up assuming a car or charger will work, then finding out it does not. Check first. It takes 30 seconds.
Expecting manual control. Intelligent Go works best when you plug in and let it handle the schedule. If you want to decide exactly which hours the car charges every night without any automation, regular Octopus Go or a fixed tariff may feel more comfortable.
Day rate is not the cheapest available. Intelligent Go's day rate is competitive but not the lowest on the market. If most of your electricity usage happens during the day and your car charging is minimal, the maths may not work in your favour. The tariff favours high overnight usage.
Switching away can be slow. Octopus does not charge exit fees, but the switch process to another supplier can take a couple of weeks depending on the gaining supplier. Not a dealbreaker, just something to know.
Who Intelligent Octopus Go Is Best For
- EV owners with a compatible car or charger who charge at home regularly
- Drivers who want low-effort, automated cheap charging
- Households that can shift other usage (appliances, heating) into the overnight window
- People already using or interested in Electroverse for public charging
Who Might Want Something Else
- Drivers without a compatible car or charger (Octopus Go is the simpler alternative)
- Households with very low overnight usage where the day rate matters more
- People who strongly prefer full manual control over charging schedules
- Renters who cannot install a home charger and rely entirely on public charging
Intelligent Octopus Go is available to UK customers with a compatible EV or charger. Check the live rates and whether your setup qualifies. The switch from another supplier is free and takes about three weeks.
Common Questions
Is Intelligent Octopus Go still worth it in 2026?
Yes, for compatible EV owners it remains one of the strongest tariffs available. The 8p/kWh smart charging rate, six hours of cheap overnight electricity, and Electroverse public charging discount together create savings that are hard to match elsewhere. The tariff works best when most of your electricity usage can be shifted into the cheap overnight window.
What is the difference between Octopus Go and Intelligent Octopus Go?
Intelligent Go gives you six hours of cheap electricity with smart scheduling that adapts to your car's battery level. Regular Octopus Go gives you four fixed hours (00:30 to 04:30) at a similar cheap rate but with no smart scheduling. Intelligent Go requires a compatible car or charger. Regular Go does not. Intelligent Go also includes the Electroverse 8% public charging discount.
How do I know if my car is compatible?
Check the live compatibility list on Octopus Energy's website before signing up. Most Teslas, Volkswagen ID models, Audi e-trons, and several others are supported. Some popular EVs are still not on the list, and compatibility changes as Octopus adds new integrations. If your car is not supported but your charger is, you can often connect through the charger instead.
Does Intelligent Octopus Go save money if I do not drive much?
It depends on your overall usage pattern. If you drive 5,000 miles a year and charge entirely at the 8p rate, you will spend around £100 on car charging annually versus roughly £310 on a standard tariff. The saving is real but modest if your mileage is low. The bigger savings come when you also shift other high-consumption appliances into the cheap overnight window.
Are there exit fees if I want to leave?
No. Octopus does not charge exit fees on Intelligent Octopus Go. You can switch to another tariff or supplier at any time without penalty. The switch itself will take a couple of weeks to process depending on the gaining supplier.
Does the Electroverse discount matter?
If you use public chargers regularly, yes. The 8% Electroverse discount for linked Intelligent Octopus Go customers applies across thousands of UK public chargers and is applied automatically when you pay through the Electroverse app or RFID card. For a driver spending £40/month on public charging, that is roughly £38 saved per year with no extra effort. It is not a reason to join on its own, but it is a meaningful extra if you are already on the tariff.
I have been on Intelligent Octopus Go since 2025 and have written about Octopus tariffs extensively on this site. I drive a Tesla Model 3 Long Range, charge at home using a 7kW wall box, and regularly use Electroverse for public charging around Cornwall and on longer trips. My bills have genuinely gone down since switching despite charging a car at home most nights. The automation is what makes the tariff work. Without it, I would forget to plug in or miss the cheap window half the time.
What I have learned from two years of use is that the tariff rewards a particular kind of EV owner: someone who charges at home regularly, is happy to let the system handle the schedule, and uses enough electricity overnight to make the cheap rate count. If that describes you, it is hard to go wrong with Intelligent Go.
