This innovative tariff goes beyond a simple off-peak rate. It provides a fixed electricity price for 12 months, giving you peace of mind against market fluctuations, alongside a super low off-peak rate for your home between 23:30 and 05:30. Crucially, it smartly manages your EV charging, ensuring your car powers up at the cheapest and greenest times overnight.
What is Intelligent Octopus Go 12M Fixed?

- 12-Month Fixed Price: Your electricity unit rates are locked in for a full year, providing stability and predictability for your energy bills, regardless of wider market changes.

It ensures your vehicle is charged to your desired level by your set departure time, prioritising the cheapest and greenest periods available within the overnight window and beyond.
- Optimised for Green Energy: Octopus Energy's smart charging doesn't just look for the lowest price; it also considers when renewable energy sources (like wind and solar) are most abundant on the grid, helping you reduce your carbon footprint with every charge.

Considerations and Potential Drawbacks
While Intelligent Octopus Go 12M Fixed offers significant advantages, it's important to consider if it truly aligns with your needs:
- Requires a Smart Meter: To access the variable rates and intelligent charging, a working smart meter (SMETS2 or an upgraded SMETS1) is essential.
- Compatible EV or Smart Charger: Your electric vehicle or home charging point needs to be compatible with Octopus Energy's intelligent system. Check their website for the latest list of supported models.
- Potential Exit Fees: As a fixed tariff, there may be exit fees if you decide to switch away before the 12-month term ends. Always check the specific terms and conditions.
- Market Fluctuations: While fixed tariffs protect against price rises, you won't benefit if wholesale energy prices drop significantly during your 12-month term.
- Off-Peak Window Timing: The 23:30 - 05:30 off-peak window is fixed. Ensure this time suits your main energy consumption habits outside of EV charging.
