Intelligent Octopus Go 12M Fixed: Smart EV Charging for 2026
Welcome to 2026, where driving an electric vehicle (EV) is smarter and more affordable than ever, thanks to tariffs like Octopus Energy's Intelligent Octopus Go 12M Fixed. This innovative tariff isn't just about getting cheap electricity; it's about intelligent energy management that puts you in control, while Octopus handles the optimisation.
Designed specifically for EV drivers, Intelligent Octopus Go 12M Fixed combines the benefits of a super low off-peak electricity rate with cutting-edge smart charging technology. And, as the name suggests, you get the peace of mind of a fixed rate for a full 12 months, shielding you from potential market fluctuations throughout 2026.
What is Intelligent Octopus Go 12M Fixed?
At its core, Intelligent Octopus Go 12M Fixed is an electricity tariff tailored for households with electric vehicles. It offers two distinct electricity rates: a super low rate during specific overnight hours and a standard (peak) rate for the rest of the day. The 'Intelligent' part comes from its ability to communicate directly with your EV or charger, automatically scheduling your charging sessions to happen during the cheapest and greenest times available within the off-peak window.
- Fixed for 12 Months: Your electricity unit rates and standing charge are locked in for a year from the start of your tariff, providing stability and predictability for your energy bills.
- Super Low Off-Peak Rate: A dedicated six-hour window every night (23:30 - 05:30) where electricity is significantly cheaper, ideal for charging your EV or running other high-consumption appliances.
- Smart Charging Optimisation: Simply plug in your EV, tell the Octopus Energy app when you need your car ready by, and Intelligent Octopus Go will manage the charging. It uses real-time grid data to ensure your car charges when electricity is not only cheapest but also when it's greenest, reducing your carbon footprint.
Current Rates for Intelligent Octopus Go 12M Fixed (as of early 2026)
Understanding your energy costs is vital. Here are the rates you can expect with the Intelligent Octopus Go 12M Fixed tariff:
- Off-Peak Electricity Unit Rate (23:30 - 05:30): 31.7449p/kWh (inc VAT)
- Standing Charge: 45.4657p/day (inc VAT)
- Peak Electricity Unit Rate: (Applies outside of 23:30 - 05:30) Please note, while the off-peak rate is provided, the specific peak rate is not. However, it will be higher than the off-peak rate.
These rates are fixed for 12 months once you switch, offering protection against market price increases. Bear in mind that energy prices can fluctuate, so these specific rates are subject to change for new customers in the future, although your fixed rate will remain for your agreed term.
Who is Intelligent Octopus Go 12M Fixed For?
This tariff is a game-changer for specific types of households:
- Electric Vehicle Owners: This is the primary audience. If you own an EV and regularly charge at home, this tariff is designed to maximise your savings.
- Smart Home Enthusiasts: If you have other smart appliances, such as storage heaters or a hot water tank with a smart controller, you can also leverage the cheap off-peak window for these too, manually or with compatible smart home systems.
- Households with Flexible Consumption: If you can shift a significant portion of your electricity usage (e.g., dishwashers, washing machines, tumble dryers) to the overnight off-peak period, you'll see greater benefits.
Key Benefits of Intelligent Octopus Go 12M Fixed
Opting for this tariff in 2026 brings a host of advantages:
- Significant Savings on EV Charging: The super low off-peak rate makes charging your electric car much cheaper than on a standard tariff.
- Price Certainty: Fixed rates for 12 months mean you know exactly what you'll pay per unit for an entire year, making budgeting easier.
- Automated Optimisation: Let Octopus Energy's smart tech do the hard work. Your car charges when it's cheapest and greenest, without you needing to manually intervene.
- Reduced Carbon Footprint: By charging when renewable energy sources are abundant on the grid, you're contributing to a greener energy system.
- Flexible Charging: You set your 'ready by' time, and Intelligent Octopus Go ensures your car is charged, even if it has to top up outside the cheapest window.
Things to Consider Before Switching
While highly beneficial, Intelligent Octopus Go 12M Fixed isn't for everyone:
- Higher Peak Rates: Electricity used outside the 23:30 - 05:30 window will be charged at a higher peak rate. If you use a lot of electricity during the day, you'll need to weigh this up against your off-peak savings.
- Smart Meter Required: You must have a working smart meter (SMETS2) installed at your property for this tariff to function.
- Compatible EV or Charger: Intelligent Octopus Go requires a compatible electric vehicle or smart home charger for its optimisation features to work. Check the Octopus Energy website for an up-to-date list of compatible models.
- Not for Non-EV Owners: If you don't own an electric vehicle, a different Octopus Energy tariff might be more suitable for your needs.
Is Intelligent Octopus Go 12M Fixed Right for You in 2026?
To determine if this tariff is your ideal energy solution, consider your lifestyle and energy habits:
- How much do you drive your EV? High mileage drivers who charge at home frequently will see the biggest savings.
- How flexible is your energy usage? Can you shift tasks like running the dishwasher or washing machine to the overnight off-peak window?
- Do you have the necessary equipment? Ensure you have a smart meter and a compatible EV/charger.
Compare your current energy usage patterns with the potential savings from the low off-peak rate. Don't just look at the low rate in isolation; consider your overall consumption across both peak and off-peak periods.
