Octopus Go vs Intelligent Go
Octopus Go is a simpler EV tariff with a shorter and fixed off-peak charging window. Whereas Intelligent Octopus Go gets 6 core overnight hours with the possibility of extra slots.
The Octopus Go off-peak rate is slightly higher than Intelligent Octopus Go, but it’s predictable and standard Go doesn’t rely on the Octopus app for scheduling.
This is good for EV drivers who want a straightforward, no-fuss overnight option or don’t have a device compatible with Intelligent.
The key differences between Octopus Go and Intelligent Octopus Go are the length of the cheap window, pricing level and smart charging requirements.

| Off peak window | Fixed 00:30 to 05:30 | Core 23:30 to 05:30 plus possible extra slots |
