Octopus Go Review 2026: Fixed Overnight Rate, No Smart Device Needed

Octopus Go is the straightforward overnight EV tariff from Octopus Energy. There is no smart dispatch, no compatibility checklist, and no app pairing required. You get a 9.5p/kWh off-peak rate between 00:30 and 04:30 every night, and the cheap rate applies to your whole home, not just your car. Set your timer and charge.

This review covers what Octopus Go offers, who it suits, how it compares to Intelligent Octopus Go, and when a different tariff might serve you better.

How Octopus Go works

Octopus Go is a two-rate time-of-use tariff. During the overnight window (00:30 to 04:30) you pay 9.5p/kWh for all electricity used in your home. Outside that window you pay the peak rate of 33.72p/kWh.

To benefit, you simply set a charging timer on your electric vehicle or home charger to start at 00:30. Your car will charge during the cheap window and stop at 04:30 (or whenever your target charge is reached, if set earlier). No app pairing, no smart charger, no compatibility check required.

The whole-home rate means your other appliances also benefit. Running the washing machine, dishwasher, or tumble dryer during the 00:30–04:30 window extends the saving beyond EV charging alone.

Octopus Go rates at a glance

Rate	Unit	Applies
Off-peak	9.5p/kWh	00:30–04:30 daily
Peak	33.72p/kWh	All other times
Standing charge	53p/day	Always

A 60kWh battery charged from empty during the overnight window costs around £5.70, compared with roughly £15 at a standard variable tariff rate of around 25p/kWh.

Octopus Go vs Intelligent Octopus Go

The natural comparison is Intelligent Octopus Go, which offers an 8p/kWh rate via smart dispatch within a longer 11pm–5am window.

The key difference is that Intelligent Octopus Go requires a compatible smart charger or a compatible electric vehicle. If you have an Ohme Home Pro, Indra Smart Pro, Hypervolt Home 3 Pro, or a compatible EV, Intelligent Octopus Go will generally be cheaper because the smart dispatch can find the lowest-cost slots within the larger window.

Octopus Go suits drivers whose car or charger is not on the Intelligent Octopus compatibility list, or those who simply prefer the predictability of a fixed window over smart scheduling.

Smart meter requirement

Both Octopus tariffs require a SMETS2 smart meter. Octopus will arrange free installation if you do not have one, though wait times vary by region. Without a smart meter, Octopus cannot read half-hourly consumption data and cannot apply the off-peak rate correctly.

Is Octopus Go the cheapest option?

Octopus Go is competitive but not the cheapest fixed-window tariff currently available. EDF GoElectric Overnight offers 6.99p/kWh across a longer 7-hour window (midnight to 7am) with a lower peak rate of 25.66p/kWh. E.ON Next Drive offers 9p/kWh with a similar window.

Octopus Go makes sense if you are already with Octopus and want minimal disruption, if your priority is brand trust or the Octopus app, or if you plan to upgrade to a compatible smart charger and switch to Intelligent Octopus Go in the near future.
