Octopus Go vs Intelligent Octopus Go (2026 Comparison)

Octopus Energy remains the dominant force in the UK electric vehicle tariff market. However, choosing between their two flagship offerings—Octopus Go and Intelligent Octopus Go—can be confusing.

In short: Intelligent Octopus Go is cheaper (around 7p/kWh) and offers a longer charging window, but it requires specific, compatible hardware. Octopus Go is slightly more expensive (around 8.5p/kWh) with a shorter window, but works with almost any EV and a standard smart meter.

Let's break down the exact differences for 2026.

Comparison Table

| Feature | Octopus Go (Standard) | Intelligent Octopus Go | | :--- | :--- | :--- | | Off-Peak Rate | ~8.5p / kWh | ~7.0p / kWh | | Peak Rate | ~33.72p / kWh | ~33.72p / kWh | | Standing Charge | ~61.43p / day | ~61.43p / day | | Off-Peak Window | 12:30 AM to 4:30 AM (4 hours) | 11:30 PM to 5:30 AM (6 hours) + dynamic day slots | | Hardware Needed | Any EV + Any Smart Meter | Compatible EV or Compatible Charger + Smart Meter |

Intelligent Octopus Go: The Smart Choice

If your hardware allows it, this is the tariff you want.

Pros:

• Cheaper: At ~7p/kWh, it's one of the cheapest ways to charge a car in the UK.
• Longer Window: You get a guaranteed 6 hours of off-peak electricity every night.
• Smart Scheduling: You plug in, tell the app what charge percentage you need by what time, and Octopus handles the rest. If the grid is exceptionally cheap during the day, they might even charge your car at the 7p rate outside the normal nighttime window!

Cons:

• Strict Compatibility: You must have a compatible car (like a Tesla, Ford, VW) OR a compatible smart charger (like an Ohme Home Pro or Zappi). If you have an older Nissan Leaf and a basic "dumb" charger, you cannot get this tariff.

Octopus Go (Standard): The Reliable Fallback

Pros:

• Universal: Works with virtually every EV and plug-in hybrid on the road. You just need a standard communicating smart meter (SMETS2).
• Predictable: You always know exactly when your electricity is cheap. You can confidently run your dishwasher and washing machine on a delay timer between 12:30 AM and 4:30 AM.

Cons:

• Shorter Window: 4 hours might not be enough to fully charge a massive battery (like an Audi Q8 e-tron) from 0-100% on a standard 7kW charger in a single night.
• Higher Rate: You pay a premium (around 1.5p/kWh more) compared to the Intelligent tier.

Use Case Breakdown: Which Should You Choose?

• Choose Intelligent Go if: You are buying a modern EV or installing a new smart charger anyway. The savings over a year easily justify ensuring your hardware is compatible.
• Choose Standard Go if: You rent a home with an existing basic charger and drive an older EV, making it impossible or cost-prohibitive to upgrade your hardware just for the tariff.

How to Switch

1. Check your meter: Ensure you have a functioning smart meter. If you don't, Octopus will usually install one for free, but it takes time.
2. Check compatibility: Visit the Octopus website and use their compatibility checker to see if your car or charger qualifies for Intelligent Go.
3. Sign up: Switch your supply to Octopus. You'll usually be placed on a standard flexible tariff for a few days while they connect to your smart meter.
4. Connect: Once the meter is reading half-hourly data, request the switch to the EV tariff via the Octopus app.

FAQ

Can I use the cheap electricity for my house? Yes! On both tariffs, the cheap off-peak rate applies to your entire house, not just the car charger.

What happens if I plug in during the day on Intelligent Go? If you need an immediate charge outside the smart schedule, you can hit "Bump Charge" in the app. However, you will pay the peak rate (approx. 33.72p/kWh) unless the app determines it's a dynamic cheap slot.
