Smart tariffs for electric vehicle (EV) charging help you charge your car when electricity is cheapest, saving money and reducing strain on the grid. For example, Octopus Energy offers a plan called Octopus Go, which gives you a much lower rate for electricity during the night—usually between 00:30 and 04:30—so you can fully charge your car while you sleep. There’s also Intelligent Octopus Go, which connects directly to your EV or smart charger and automatically schedules charging when electricity prices are lowest and the grid is greenest. You simply plug in your car, set when you need it ready, and the system takes care of the rest. These smart tariffs make owning an EV cheaper and more convenient by letting you charge at off-peak times and use cleaner, lower-cost electricity. Other energy providers also provide EV tarrifs.
