What are electric vehicle tariffs?
Electric Vehicle (EV) tariffs are aimed at electric vehicle owners who charge their car at home. They're designed to keep car-charging costs down and encourage wider adoption of cleaner, greener cars.
To qualify for an EV tariff, you’ll typically have to prove you own an electric car. You’re also likely to have to have a smart meter installed at your home.
How do EV tariffs work?
EV tariffs break down into two broad categories. These are:
Two-rate tariffs: These offer cheaper electricity at night, enabling you to cost-effectively charge your car overnight. They’re very much like traditional Economy 7 tariffs.
Single-rate tariffs: These offer the same rate around the clock. But typically will be available at a discounted rate to EV owners. Alternatively, EV owners on these tariffs are given bill credit.
How much is an EV tariff?
That totally depends on your provider, the tariff you choose and the car you drive. And how and where you drive it, too.
But for the most part, it’s fair to say that EV tariffs are generally cheaper than household energy tariffs, because the former typically offer lower rates when you’re using electricity outside peak hours.
Our expert says…
Data from Transport & Environment suggests that prices for electric vehicles will be in line with petrol and diesel cars by 2027 at the latest, after which point adoption is expected to surge.
Whether the UK's charging infrastructure will be able to cope with increased take-up is uncertain, so if you can get a home charger installed, it could be a very, very good idea.

Is it worth getting an electric car?
Prices for electric vehicles have come down a fair bit in recent years, but EVs generally remain a more expensive option to buy than a standard petrol car. That means that unless you go down the car finance route or lease an EV, you’ll probably have to lay out more to get an EV than a traditional car.
However, you can pick up an EV for a good price if you opt for a used model. And by the time you factor in the typically lower cost of running an EV compared with petrol powered vehicles, the maths should work out that you’d be saving money in the long run.
In two minds about investing in an EV? We weigh up everything you need to consider in our guide to buying an EV.

Which energy suppliers have EV tariffs?
Generally, EV tariffs are only available from household-name providers. That’s to say those are part of the traditional big-six.
At the time of writing, big-name suppliers that offer EV tariffs include British Gas, EDF Energy, Octopus Energy, OVO Energy and Scottish Power.
Do I have to be an existing customer to get an EV tariff?
You may have to be. Some providers will only accept you for an EV tariffs if you already take your household energy from them.
In the event that the EV tariff provider you're looking at does apply this policy, you'll need to switch your domestic energy to them in order to get the EV tariff.
Do I need a smart meter to get an electric vehicle tariff?
Most EV tariff providers will insist you have a smart meter to qualify. Besides which, with dual tariffs you'll need a smart meter to benefit from the cost savings on offer from charging your electric vehicle at night.
