We explore the best electricity tariff for home battery & EV owners

It’s now November and long sunny days exporting solar to the grid are long gone and you now want to know the best way to save money with your battery…….we explore your options with different suppliers.

If you’re charging an electric car at home, you’ll save money by switching to an EV tariff. Basic EV tariffs have a fixed off-peak window, like Octopus Go. Smarter EV tariffs, like Octopus Intelligent and OVO Charge Anytime, match your charging with the greenest energy, meaning lower-carbon charging and even bigger savings.

The best EV tariff depends on your car and your home energy use. It’s a balance between how much charging you do at home, how much energy you use during the day and whether you could shift any energy use overnight to benefit from cheaper rates. This last point can make a real difference when you compare two leading EV tariffs: Octopus Intelligent v.s OVO Charge Anytime

1. Best EV tariff for overall savings

Octopus Energy’s Intelligent Octopus, is a smart EV tariff with a minimum six-hour off-peak window for charging and home energy use. You use an app to schedule your charging and let Octopus get on with charging when it is greenest. You’ll pay 7.5p/kWh for off-peak electricity, much less than the 9.5p/kWh off-peak on the basic Octopus Go EV tariff. You may get some charging outside of the off-peak hours, in which case you’ll get some extra cheap home energy too. Lots of cars are compatible, but if yours isn’t on the list, you can connect through an Ohme charger.

If you have solar panels, Intelligent gets even better. You’ll now get a fixed rate of 15p for every kWh you export. This is much higher than the 4.1p SEG that you’d get with the Go tariff.

Off-peak: 23:30-05.30

✔ Long off-peak for home energy
✘ Compatible car or charger needed

2. Best ‘set and forget’ EV tariff for any car or charger

Octopus Go was once the go-to tariff for EV drivers. But, at 9.5p per kWh, it’s more expensive than the smarter Intelligent Octopus tariff and there are only four hours at off-peak rates each night, compared with at least six. If you have solar, you’ll get a lower amount for the energy you export.

Why do we still rate it? It’s simple, and available to drivers of any make of EV and with any home charger or home storage.

4. Best EV tariff for daytime charging

OVO’s Charge Anytime, is just for your EV. You’ll get the 10p/kWh rate no matter when your car charges if you use their scheduling app and leave OVO to manage charging around your life.

When you get Charge Anytime you’ll also choose an OVO tariff for your home use, including the default Standard Variable Tariff. The downside of OVO’s new electric car only tariff is that you’ll only get your EV charging at the cheaper rate. All your home electricity use is charged at your standard unit price.
