What are EV tariffs?
EV tariffs are specifically targeted at drivers of electric vehicles so they can charge their vehicles at home in the most affordable way.
The options currently available on the market work in a similar way to Economy 7 and time of use (TOU) tariffs. You will get discounted electricity unit rates for charging your vehicle during off-peak hours – usually overnight.
While EV tariffs are aimed at electric vehicle owners, the cheaper unit rates often apply to all electricity usage during off-peak hours. This means you can save money on household activities, like running a washing machine or dishwasher.
Variable EV tariffs offering a dual-rate are covered by the Ofgem energy price cap, while fixed deals are not. Suppliers have to come in below a weighted average unit rate that considers typical day and night usage for households.
The exact rate varies by region. You should contact your energy supplier to find out what your exact rates would be.
Am I eligible for an EV tariff?
To qualify for an EV tariff, you need to own an EV charger and have a smart meter fitted. This is so your energy supplier can accurately measure how much energy you use - and when you use it. Some suppliers also require you to be an existing customer. If you aren’t already with that provider, you may have to switch to one of their other tariffs before switching across to their EV-specific deal.
On top of this, you’ll likely need to provide proof of owning an electric vehicle. Some suppliers have restrictions on the makes and models they supply, so it’s worth checking whether the vehicle you have or want to buy is included. For example, Ovo Energy has a full list of EVs it will supply energy for. Your provider may also only support certain types or brands of chargers.
Another key thing to check when signing up for this kind of tariff is whether it’s single or dual fuel. Some suppliers offer electricity-only products, meaning if you have gas, you will need to get a separate tariff for it.
Is it worth getting an EV tariff?
You can potentially save hundreds of pounds a year with an EV tariff compared to if you charge your EV using a standard tariff. Exactly how much you can save will depend on the type of vehicle you own, your usage, driving distances and how much of your general energy consumption you can shift to off-peak times.
Introducing an EV into your household can potentially increase your energy consumption by up to 50%. However, EV tariffs provide off-peak rates that are substantially cheaper than those offered by Economy 7 tariffs (time-of-use tariffs can vary daily so it’s hard to compare). As long as you’re doing the bulk of your charging at home and this is taking place outside of peak hours, an EV tariff is likely to be a good bet to keep your bills down.
According to OVO, charging an EV with its Charge Anytime tariff works out at less than 2p a mile – around 80% less than the price of petrol. Meanwhile, EDF Energy says you can do a 20-mile commute for 51p with its GoElectric Overnight EV tariff.
If you are thinking about buying an electric vehicle, it’s worth looking at which suppliers offer bundles that may help you save on charger installation costs. The government also offers a grant of £350 (or 75% off the cost of getting a socket, whichever is lower) if you want a charger but live in a flat or rented accommodation.

How to save money with an EV tariff
Here are a few ways to maximise your savings with an EV tariff:
- Optimise your EV charging: If you have a smart charger, take advantage of off-peak times by powering up your vehicle when costs are at their lowest. You’ll be able to manage your battery’s charge level and set a minimum threshold to prevent your EV from running low.
- Use your energy-hungry appliances at night: Whether it’s dishwashing duties or laundry day, it’s worth rethinking your appliance schedule. EV tariffs allow you to use any electricity at a discounted price in off-peak hours, so you can save on your energy bills by using energy-hungry appliances at a cheaper time.
- Watch out for daylight savings: Clock adjustments could alter your off-peak windows by an hour. Make sure to stay on top of these changes by checking with your energy supplier.
- Drive your EV efficiently: By adopting economical driving habits like smooth acceleration and braking, sticking to speed limits and not overusing your heating or air con, you could reduce your overall charging needs and keep your costs down.
