Charging at home is the cheapest and most convenient way to add miles to your electric car. EV-friendly 'time-of-use' tariffs mean you not only pay less to charge, but by shifting your charging out of the evening energy rush hour, you'll also reduce the carbon behind each mile you drive.
Here we've brought together a complete list all the available EV electricity tariffs from the likes of EDF, E.On, British Gas, and Scottish Power, as well as from smart challengers, like Bulb, Ovo and Octopus Energy.
We start with the cheapest off-peak rate, but don't forget to look at the day rates and the daily standing charge, which can be higher than on other tariffs. To compare how each tariff works not only for your charging but all your home use too, try a free EV tariff comparison.

For this list, we’ve assumed monthly direct debit payments and paperless bills. If you choose to pay quarterly or annually, or you have paper bills, some of these prices may change.
All EV energy tariffs in the UK guarantee 100% renewable energy, although the way in which they back this promise does vary.

What's the best EV energy tariff for me?
An EV adds around a month's electricity use (250 kWh) for every 1,000 miles you drive. An average UK driver doing 8,000 miles would add around £30/month to their electricity bill by charging an electric car without switching tariff.

Whilst the off-peak rates can be quite appealing, remember that these tariffs might not always offer the best value if you have higher home use that you can't shift - especially if you're not doing very high mileage in your electric car.
Some of these tariffs are compatible with economy 7 and 10 meters - but most work with a smart meter. Speak to your utility about getting a smart meter installed.
How to choose an EV-friendly tariff
Choosing between EV tariffs can tricky, as you'll have to make a judgement on the amount you will use at peak and off-peak rates. On top of that, you'll have to work out what any extra benefits that the utility has bundled in are worth to you.
Several companies offer 'free miles' when you plug in overnight. But don't forget to look at the rates they give you for electricity at any other time of the day, and the standing charge. Depending on your home use and how much you actually plug your EV in at night, you might end up paying more.
Some, like Ovo Energy, offer a free or discounted charger installed at your home. This might suit you if you are considering buying your first an electric vehicle, but the unit rates might not stack up if you are already set up to charge at home.
Many companies offer you free membership to a nationwide network of road chargers, or a discount on roadside prices. Unless you can't charge at home, or are regularly doing very long journeys, you might find it more convenient to charge overnight at home.
Economy 7 meters and EVs
Most electricity suppliers will require you to fit a smart meter to your property before you can switch to one of their EV tariffs. They will generally do this for free. However, if you can't do this yet (generally because of lack of mobile phone coverage these meters need) it’s also worth looking into having an Economy 7 or Economy 10 meter fitted to your property. This will allow you to take advantage of cheaper rates at off-peak times on several tariffs.
Does an electric car mean higher electricity bills?
Running costs for electric cars are much lower than a conventional car, but charging your car increases your home electricity consumption considerably. One unit (a kWh) will allow you to drive 3.5-4 miles. Some high-mileage drivers nearly double their energy use with home charging. If these drivers don't switch, their bill with double too.
An average driver will see their use going up by around 50%. Switching to an EV tariff can mean paying about the same as before, especially if you can shift other use into the off-peak hours. As well as switching tariff, check out our top tips for saving money on EV charging.
