EDF GoElectric Review 2026: 9p/kWh Overnight Rate, No Smart Charger Needed

EDF GoElectric Overnight is the EV tariff for drivers who want cheap overnight charging without any smart hardware requirements. At 9p/kWh across a fixed midnight-to-5am window, it works with any EV and any charger; no compatibility lists, no app pairing, just a timer.

The peak rate of 26.69p/kWh is one of the lowest of any major EV tariff, beaten only by British Gas Electric Driver’s 25p/kWh. For households that use significant electricity during the day and also want cheap overnight EV charging, GoElectric offers one of the best combinations of rates available.

This review covers everything you need to know about the GoElectric Overnight tariff, including the exit fee caveat that applies.

What GoElectric Overnight offers

GoElectric Overnight is a whole-home time-of-use tariff with a fixed overnight window from midnight to 5am every day. The 9p/kWh rate applies to all electricity drawn from the grid during those 5 hours; your EV charging, washing machine, dishwasher, and any other appliance you run overnight.

Outside the off-peak window, you pay the peak rate of 26.69p/kWh. The standing charge is 46p/day.

There is no smart dispatch. To benefit, you set a charging timer on your car or charger to start at midnight. At 7.4kW charging speed, a 5-hour window provides around 37kWh of added charge; enough for the daily top-up most drivers need, though a fully depleted large battery may take two nights.

The rate comparison

Tariff	Off-peak	Peak	Standing charge
EDF GoElectric Overnight	9p/kWh	26.69p/kWh	46p/day
E.ON Next Drive Smart	8p/kWh	27.76p/kWh	50p/day
Intelligent Octopus Go	8p/kWh	33.72p/kWh	53p/day
Octopus Go	9.5p/kWh	33.72p/kWh	53p/day

GoElectric no longer wins on the overnight rate; the 8p smart dispatch tariffs are cheaper. But it has the lowest peak rate and the lowest standing charge in this comparison, which matters for whole-home costs.

On a 60kWh battery from empty, GoElectric costs around £5.40 at 9p. The same charge costs £4.80 on Intelligent Octopus Go at 8p, and £5.70 on Octopus Go at 9.5p.

The smart dispatch trade-off

The one area where GoElectric falls behind Intelligent Octopus Go and E.ON Next Drive Smart is smart dispatch. Those tariffs actively optimise when within the overnight window your car charges, and both undercut GoElectric’s overnight rate by 1p/kWh. GoElectric does not optimise anything; you simply charge during the fixed 5-hour block.

The trade-off is eligibility. Smart dispatch tariffs need a compatible charger or EV on the supplier’s list; GoElectric needs nothing beyond a smart meter. If your charger is not on Octopus’s or E.ON’s compatibility list, GoElectric is one of the strongest tariffs you can actually access.

For straightforward, predictable overnight charging with a low day rate and no hardware requirements, GoElectric remains a solid choice.

The exit fee

EDF GoElectric Overnight carries a £75 exit fee if you leave before the end of your contract term. This is the tariff’s main drawback compared to Octopus Energy and E.ON Next, which charge no exit fees.

The practical implication is that you should be confident you want to stay with EDF for the contract duration before switching. If wholesale energy prices fall significantly and a better tariff becomes available mid-term, you would need to pay £75 to move. For most drivers who plan to stay for at least 12 months, this is not a major concern; but it is worth knowing.

Smart meter and setup requirements

GoElectric requires a SMETS2 smart meter. EDF will arrange installation if you do not have one. No specific charger model or EV is required beyond the smart meter.

Check your current energy supplier for any exit fees that might apply before switching.
