How Does Octopus Intelligent Go Work

Electric car ownership in the UK has brought with it new ways to think about energy, charging, and household electricity use. One of the most innovative developments in this space is Octopus Intelligent Go, a smart electricity tariff designed specifically for EV owners who charge their cars at home. Instead of relying on flat-rate energy pricing, this system uses intelligent scheduling to charge your car when electricity is cheapest and greenest, helping you save money while supporting a cleaner energy grid.

But how exactly does Octopus Intelligent Go work? What makes it different from other tariffs, and how can it help you cut down on household energy bills? In this article, we’ll explore in detail how the tariff functions, how it communicates with your electric vehicle and charger, and how you can make the most of it. Whether you already own an EV or are planning to buy one, understanding this system can help you take full advantage of off-peak energy pricing and sustainable charging habits.

What Is Octopus Intelligent Go?

Octopus Intelligent Go is a time-of-use electricity tariff created by Octopus Energy for electric vehicle drivers. It’s part of the company’s broader effort to make energy more flexible and sustainable by encouraging consumers to use electricity at times when demand is low and renewable energy generation is high.

The tariff works by offering a cheaper electricity rate for a set period overnight, typically between 11:30 pm and 5:30 am. During these hours, the cost of electricity can drop to as little as 7.5p per kilowatt-hour, compared to the standard daytime rate, which can be two to three times higher.

What makes Octopus Intelligent Go different from standard off-peak tariffs is its use of smart technology. It connects directly to your electric car or smart charger to automatically schedule charging when rates are cheapest. You don’t need to worry about plugging in at the right time or setting manual timers—the system takes care of everything.

How Does Octopus Intelligent Go Work?

The process is designed to be as simple and automated as possible. Once you’ve signed up and linked your compatible car or charger, Octopus Energy uses its smart system to monitor both your vehicle’s state of charge and the wider energy grid. When you plug in your car, the system checks how much energy it needs and how long it has before your chosen “ready by” time.

For example, if you plug your car in at 8 pm and tell the app that you need it fully charged by 7 am, Octopus Intelligent Go will calculate the most cost-effective way to deliver that energy overnight. It will automatically schedule the charging during off-peak hours when electricity is cheaper and greener, but if extra charging is needed outside those hours, it will still ensure your vehicle is ready on time.

The system is dynamic, meaning it can adjust in real time based on grid conditions. If there is a surplus of wind or solar energy during the night, your car might charge earlier or later depending on where clean electricity is most available. This helps balance the UK’s energy network and reduces reliance on fossil fuels.

Smart Charging Technology Explained

The intelligent part of the tariff comes from how it integrates with smart devices. Octopus Intelligent Go can connect directly to many popular EV models and smart home chargers, including brands such as Tesla, Volkswagen, Hyundai, Kia, and Ohme.

Through these connections, the system can remotely control when your car draws power from the grid. Instead of relying on a simple timer, it uses real-time communication between your vehicle, the charging device, and Octopus Energy’s platform. This allows it to pause, resume, or adjust charging automatically based on the cheapest periods of the night.

The smart platform uses algorithms that predict demand, renewable generation, and wholesale electricity prices. By spreading out EV charging across the country, it helps stabilise the grid while giving drivers the lowest possible cost for every kilowatt-hour used.

The Role of the Octopus App and “Ready By” Settings

When you join the Intelligent Go tariff, you manage your charging through the Octopus Energy app. Here you can set your preferred “ready by” time, meaning the time you want your vehicle to be fully charged and ready to go.

The app allows you to plug in your car at any time, day or night, without worrying about when charging actually starts. You simply tell the system when you’ll need the car, and it calculates the optimal charging window. If you need to override the schedule for instance, if you need to leave earlier than usual you can start an immediate charge manually at the normal daytime rate.

This feature gives flexibility while maintaining efficiency. It’s especially useful for drivers with variable schedules, as it ensures the car is always ready without unnecessary energy waste or expense.

Savings Compared to Standard Tariffs

The main advantage of Octopus Intelligent Go is the potential cost savings. The average UK electricity rate under a standard tariff is around 30p per kilowatt-hour. By contrast, the Intelligent Go off-peak rate is 7.5p per kilowatt-hour for six hours every night.

For example, if your EV battery has a capacity of 60 kWh and you need to recharge from 20 percent to full, that’s around 48 kWh of electricity. On a standard tariff, this might cost roughly £14, while on Octopus Intelligent Go it could cost around £3.50. Over the course of a year, the savings can be substantial potentially several hundred pounds, depending on how often you charge at home.

In addition to cheaper charging, any household appliances or systems used during the off-peak period will also benefit from the reduced rate. This means you can save further by running dishwashers, washing machines, or storage heaters overnight while the tariff is active.

Environmental Benefits of Intelligent Charging

Aside from financial savings, Octopus Intelligent Go also helps reduce carbon emissions by encouraging smarter energy use. The system schedules EV charging when renewable generation is strongest, typically at night when wind energy output is high and national demand is low.

By shifting power consumption to these cleaner periods, Intelligent Go supports a more sustainable electricity network. It also helps prevent overloading the grid during peak daytime hours, reducing the need for fossil-fuel-based backup power plants. For environmentally conscious drivers, this approach offers a simple way to contribute to the UK’s net zero goals without changing daily habits.

Installation and Compatibility

To use Octopus Intelligent Go, you need a compatible smart charger or an electric car that can communicate directly with the Octopus system. The list of compatible vehicles and chargers is continually expanding, but popular models such as Tesla, Hyundai Ioniq, Kia EV6, and Volkswagen ID range are already supported.

If your car is not compatible, you can still benefit from similar savings by pairing the tariff with a supported charger, such as an Ohme Home Pro or Wallbox Pulsar. The charger acts as the intermediary, controlling when energy flows based on the Intelligent Go schedule.

Installation of a smart home charger typically requires a qualified electrician who can ensure the connection meets UK safety standards under Part P of the Building Regulations. Once set up, your charger and the Octopus system work together automatically without manual input.

How Octopus Intelligent Go Compares to Other Tariffs

Octopus Energy offers several EV-friendly tariffs, but Intelligent Go stands out because of its automation. Tariffs like Go and Go Faster also offer off-peak rates, but they rely on fixed time slots that do not adjust dynamically. Intelligent Go’s adaptive scheduling makes it more efficient for real-world use, particularly as the UK grid moves towards a more flexible energy model.

Compared to fixed-rate energy tariffs, Intelligent Go provides a tangible way to reduce costs without cutting usage. Drivers can continue charging as needed while still benefiting from smart optimisation that keeps bills lower.
