Questions

Does Octopus Go need a specific charger?
No. Go is a fixed overnight window, so any charger with a timer works. Intelligent Octopus Go needs a compatible car or charger because Octopus controls the charging.
Is the Go day rate higher than the price cap?
Usually, yes. The tariff pays for its cheap window with a day rate a little above the cap, which is why it only makes sense if a large share of your use lands in the window.
