What is an EV tariff?
EV tariffs are designed for electric vehicle owners who charge their cars at home. Unlike other energy tariffs, EV tariffs work with smart meters to offer lower electricity rates during off-peak hours – like the British Gas EV tariff, where you get super-cheap electricity between 12am and 5am every day.
The higher daytime rates are balanced out by lower nighttime costs, helping you save money when you charge your EV overnight.
Why choose our EV tariff?
- It works with any make of EV and home charger
- From 12am-5am every day, you’ll get a super low off-peak price for electricity. That's 35 off-peak hours every week to charge your car for less
- We keep the daytime rate on our EV tariff as close as possible to our normal electricity rates, so you get great value all day
- We offer one, easy-to-understand EV tariff designed for all EV drivers
You can save more on electricity with our EV tariff
Owning an electric vehicle is great for lowering your carbon footprint, but we think it should be good news for your wallet, too. Charging at home is often cheaper than using public charging stations, and the savings get even bigger if you’re on an EV tariff.
There are no rules on what you can use the cut-price electricity for during off-peak hours. So, as well as charging your EV during off-peak hours, you could:
- Use higher-energy appliances, like washing machines and dishwashers.
- Charge up your smartphones, laptops and tablets.

Compare EV charging costs
Want to know how much you could save with an EV tariff? Our savings calculator does just that. It'll show you the annual and per-charge savings you could make compared to your current electricity tariff, and using public chargers. We'll even show you the estimated reduction in CO2 emissions versus a traditional petrol vehicle.
How to use the savings calculator
To estimate what you could save, just enter your car model, expected annual mileage, and how much you're currently paying for your electricity (if you’re not sure, we can compare costs to current Ofgem price cap rates).
You'll be able to see just how much you can save every time you charge, and what that adds up to over a year.

How we work out your EV tariff quote
When you get a quote for our EV tariff, we’ll estimate your annual costs. We base this on how much electricity you’ve used in the past. If we don’t know this, we’ll base it on the average amount EV owners normally use.
EV owners typically charge their vehicles about three times a week during off-peak hours, and twice a fortnight during peak hours using 10 kWh of electricity each time. Our estimate assumes that 33% of the total electricity you use is during off-peak hours.
Remember that factors like your car’s age, charging habits and how else you use electricity at home could mean your actual yearly costs differ from our estimate.
Got an EV charger and a home battery?
If you have both an EV charger and a home battery, Charge Power is the tariff for you. It offers the same low overnight rate from 12am to 5am as our EV tariff, but is designed for homes with solar and battery systems.
You can charge your EV and your battery overnight, then use stored energy during the day - saving money and using more renewable power.

Frequently asked questions
Are EV tariffs good value?
For most households with an electric vehicle, an EV tariff could save you money. If you don’t charge much at home or you need to regularly charge your car during peak hours, you won't get the most value from an EV tariff – but otherwise it's a great option.

And check out our Are EV tariffs worth it? blog for more about how they work, their benefits, and how they can save you money on charging costs.
Will my daytime electricity rate be higher on the EV tariff to offset the cheaper nighttime rate?
Our EV energy tariff is a 'two-rate' tariff that gives you cheaper electricity overnight. You can take advantage of this low-price electricity to charge your car, and power your energy-hungry appliances like washing machines and dishwashers for less.
We try to keep the daytime rate for our EV tariff as close as possible to our normal electricity rates, but they are higher.
When you get an energy quote online, we’ll show you the prices on our EV tariff and all our other tariffs, so you can choose what’s right for you.
How do I sign up for this EV tariff?
If you’re an existing customer, you can simply switch to our EV tariff in your online account. If you’re thinking about joining us, you can get a quote for our EV tariff online in just a few minutes.
Does the EV tariff work with Economy 7?
Unfortunately, our EV tariff doesn’t work with Economy 7. Your storage heaters wouldn’t work properly if you were to switch, so it’s better for you to stay on your Economy 7 tariff.
Does the EV tariff work with solar panels?
Yes! You can sign up to our EV tariff if you have solar panels at home.
Why do I need a smart electricity meter to sign up for the EV tariff?
A smart meter tells us exactly when you’re using your electricity. We need to know how much energy you’re using during the day and during the cheaper nighttime hours so we can send you accurate bills.
Do I need a smart gas meter to sign up for the EV tariff?
No, you only need a smart electricity meter to sign up for our EV tariff. But we’d still recommend getting a smart gas meter as it can also help you save money at home. And if we supply your gas, we’d be happy to fit one for you for free.
What if I want to switch tariffs later?
If you sign up to our EV tariff, you can still switch to any of our other fixed tariffs whenever you’d like, completely free. It’s one of the best things about being with us. We’ll never trap you in a tariff you don’t want.
What happens if I move home while I’m on the EV tariff?
If you're moving home, we’d love to come with you. We’d just need to check that everything at your new home works with our EV tariff. So get in touch and we’ll look into signing you up to our EV tariff again once you’ve moved.
What if I want to sign up to the EV tariff, but it’s not possible to install smart meters in my home?
Most homes are suitable for smart meters. But sometimes, we only find out that we’re not able to fit them on installation day. If this happens, you can stay on our EV tariff, but you won’t get the cheaper nighttime rate.
In which case, it probably makes sense to switch to another tariff – just get in touch and we’ll be happy to recommend one, or you can browse all your tariff options in your online account.
