Discover Intelligent Octopus Go 12M Fixed, the smart EV tariff for 2026 that offers a super low electricity rate overnight and intelligently charges your electric vehicle at the cheapest, greenest times, all with fixed prices for 12 months.
Are you an electric vehicle (EV) owner looking to cut down on charging costs while enjoying stable energy prices? In 2026, Octopus Energy continues to innovate with tariffs designed specifically for modern households. The Intelligent Octopus Go 12M Fixed tariff is a prime example, blending smart EV charging with the peace of mind of fixed electricity rates for a full year.
Intelligent Octopus Go 12M Fixed is a cutting-edge electricity tariff from Octopus Energy, tailored for electric vehicle drivers. It's built around two core principles: providing ultra-low electricity rates during specific overnight hours and intelligently managing your EV charging to optimise for cost and environmental impact. The '12M Fixed' aspect means that your unit rates and standing charges are locked in for 12 months from the start of your tariff, protecting you from potential price rises in the energy market throughout 2026.
This tariff works seamlessly with your compatible electric vehicle or smart charger, allowing Octopus Energy to take control of your charging schedule. While you set your desired 'ready by' time, Octopus's smart technology determines the optimal moments to charge your car within a broader window, ensuring you benefit from the lowest prices and greenest electricity available.
At its heart, Intelligent Octopus Go 12M Fixed offers a super low electricity rate during an extended off-peak window: typically between 23:30 and 05:30 every night. This means any electricity you use during these hours – not just for your car – benefits from a significantly cheaper rate.
The 'Intelligent' part comes into play with your EV charging. Once you've connected your compatible EV or smart charger to your Octopus account, you simply tell Octopus when you need your car fully charged by (e.g., 7 AM). Octopus then intelligently manages the charging process, primarily utilising the cheap overnight window, but also potentially charging at other times if it identifies periods of particularly low demand or high renewable generation on the grid, ensuring you always get the cheapest and greenest charge possible for your needs.
Crucially, because it's a fixed tariff, the specific unit rates and standing charges you agree to at the start will remain constant for 12 months, providing budget stability amidst an often unpredictable energy market.
Enjoy stability and predictability with your energy bills. Your electricity unit rates and standing charges are fixed for a full year, shielding you from price fluctuations in 2026.
Benefit from significantly cheaper electricity between 23:30 and 05:30. This isn't just for your car; any appliances you run during these hours will also benefit from the reduced rate.
Octopus intelligently charges your EV at the cheapest and greenest times, taking the hassle out of finding the best charging slots yourself. You just set your desired 'ready by' time, and Octopus handles the rest.
By leveraging the low off-peak rate for both EV charging and other household usage, and with the price certainty of a fixed tariff, you could see substantial savings on your annual electricity bill.
By allowing Octopus to charge your car during periods of high renewable generation or low demand, you're actively helping to balance the grid and promote the use of green energy.
Beyond the tariff, you'll benefit from Octopus Energy's renowned customer service, which consistently receives top ratings for satisfaction.
This tariff is ideally suited for:

You must have a working smart meter to access this tariff's benefits.
While the off-peak rate is exceptionally low, the peak rate during the day will likely be higher than a standard flat-rate tariff. It's crucial to understand your overall electricity consumption patterns.
For optimal savings, you'll be relying on Octopus's system to manage your EV charging. You always have the option to override it if needed, but the intelligence is key to the tariff's value.
