EDF Energy’s GoElectric Overnight tariff holds a unique position in the UK EV tariff market. It doesn’t offer the lowest overnight rate; the 8p smart dispatch tariffs hold that. But it offers something equally valuable for many households: one of the lowest peak daytime rates in the market at 26.69p/kWh, with no smart hardware requirements at all.
If your household uses a significant amount of electricity during the day, EDF’s GoElectric Overnight can save you more overall than a tariff with a cheaper overnight rate and a higher peak.
GoElectric Overnight — how it works
GoElectric Overnight gives every customer the same 9p/kWh off-peak rate between midnight and 5am, seven days a week. There is no smart dispatch — simply set your charger or car’s built-in timer to charge during those hours and the cheaper rate applies automatically.
The 5-hour window matches Octopus Go’s slot and British Gas’s Electric Driver window. A 60kWh battery costs approximately £5.40 to charge from empty during the off-peak period, compared to roughly £15.85 at the average standard rate; note that at 7.4kW a 5-hour window supplies around 37kWh, so a large battery from empty may need two nights.
The peak rate advantage
At 26.69p/kWh, EDF’s GoElectric Overnight has one of the lowest peak rates of any major EV tariff, beaten only by British Gas at 25p. Compare it to Octopus Energy at 33.72p/kWh: a difference of 7.03p per kWh on every unit used during waking hours.
For a household consuming 10 kWh of peak-time electricity per day, that 7p difference saves approximately £257 per year compared with Octopus. That more than offsets the 1p difference between EDF’s 9p overnight rate and Octopus’s 8p rate.
This makes GoElectric Overnight a strong choice if your daytime electricity consumption is high and you want a tariff with no smart hardware requirements.
Who is GoElectric Overnight best for?
- Households with people at home during the day, including homeworkers and families with children at home
- Homes with multiple high-draw appliances used during waking hours
- Drivers who prefer a simple, predictable fixed window without managing smart dispatch
- Anyone who values the established reliability of EDF as a supplier
Who should look elsewhere?
If you primarily care about the overnight charging rate and your household uses relatively little electricity during the day, Intelligent Octopus Go (8p) or E.ON Next Drive Smart (8p) will typically be cheaper overall.
Drivers who want smart dispatch — where the tariff automatically finds the cheapest slots across a wider window — should look at Octopus or E.ON Next Drive Smart instead.
Charger and vehicle compatibility
GoElectric Overnight works with any home EV charger and any electric vehicle. There are no smart dispatch integration requirements. You need a SMETS2 smart meter, which EDF can arrange free of charge.
If you are currently an EDF customer, you can switch to GoElectric Overnight through your online account without changing supplier.

EDF’s billing and customer experience
EDF is one of the UK’s six largest energy suppliers. Billing through GoElectric Overnight is straightforward — your smart meter records your usage by time period and you’re billed at the appropriate rate. Half-hourly meter reads are transmitted automatically.
The EDF website and app allow you to view your bills, check your usage by time of day, and manage your account. The EDF app is functional but less feature-rich for EV-specific scheduling than the Octopus app.
EDF also partners with Pod Point for home charger installation. The partnership doesn’t add tariff benefits, but if you’re buying a new charger alongside the tariff, it’s worth checking availability in your area.
Our verdict on EDF GoElectric Overnight
GoElectric Overnight is an underrated tariff. Most comparison sites lead with the overnight rate, which makes the 8p smart dispatch tariffs look like the obvious winners. But EDF’s 26.69p/kWh peak rate is a genuine differentiator for daytime-heavy households.
If you work from home, have children at home, or simply use more than average daytime electricity, run the numbers on EDF versus Octopus before switching. You may find EDF works out cheaper overall, even without smart dispatch.
For low daytime usage households, Intelligent Octopus Go or E.ON Next Drive Smart will offer better overall value.
