Compare the best EV energy tariffs: learn how to keep EV charging costs low

Electric cars are cheaper to run and “fuel”, no question. But did you know you can lower the cost of charging your EV even further by switching your energy tariff? We show you how to compare energy tariffs for EVs and your charging costs.

The running costs of an EV are much lower than the petrol or diesel equivalent. This is because of a number of factors, including:

  • Electricity is cheaper than fuel (a lot cheaper)
  • Electric cars are more efficient than a petrol or diesel car
  • EVs require less maintenance (fewer parts to go wrong)

From the get-go, you could halve your “fuel” costs depending on the electric car and your electricity rate. This is the bit we want to talk to you about because your electricity rate is the main variable cost when it comes to charging your EV – but it’s a cost you can largely control.

Why change electricity supplier?

It’s much more common to switch things up nowadays, from banks to broadband and travel insurance to tariffs. Your electricity tariff is no different – in fact, there are already a range of tariffs that suit overnight car charging very nicely (such as Economy 7), but there are also an increasing number of EV-specific tariffs.

The main reason to switch is to drive down your car running costs even further. It’s a no-brainer.

Electricity tariffs for electric cars

You can see some examples of energy tariffs for electric cars below, but the general idea is to find a supplier who offers cheaper rates for when you want to charge your car or shift your charging schedules to coincide with the cheaper rates - such as overnight.

This is most commonly overnight when you’re asleep and the car isn’t doing anything, plus electricity demand is low. This means energy suppliers can often offer much cheaper rates between the hours of midnight and 4am, for example.

There are a number of options to suit your needs though. Obviously to make the most of off-peak charging, you will need a dedicated EV charge point for your home - you can compare chargers here, but if you're not sure where to start then check out our Guide to How To Choose An Electric Car Charger.

Which energy tariffs are good for electric car owners?

There are plenty of tariffs around, so it’s best to do your own research and choose a package that suits your lifestyle. However, we’ve rounded up some of the most popular and best-value tariffs for electric vehicles (EV). 

Note: these are estimates based on off-peak charging only. Your rates could also depend on where you live so be sure to get a quote from the provider first to check what rates you will be offered.

 

Octopus Go

Octopus Energy is perhaps the most well-known supplier in the UK EV world because it was one of the first to offer a flexible tariff aimed at drivers of electric cars. It also has a reputation for good customer service, while its electricity comes from 100% renewable sources.

Octopus offers two main choices when it comes to electric cars, including Octopus Go.

  • 4 hours super off-peak electricity every night
  • 5p/kWh between the hours of 12:30 and 4:30am
  • This is probably the simplest smart tariff Octopus offer

Octopus Agile

Octopus Agile is probably the most innovative and smartest energy tariffs available. Prices are dependent on grid demand, so when demand is low then the prices are low - even to the point where you will get paid to use electricity! 

The prices change every half an hour, although Octopus give you advanced notice of the prices so you can plan around them. This is an excellent tariff if you can shift you electricity usage outside the typical peak 5pm-7pm period. The changing prices, however, do make it complicated to compare car charging costs. 

Tip: the Ohme Intelligent Wall Charger is the perfect companion for Octopus Agile. Because it syncs with your energy tariff, it knows what the Agile prices are in advance and can automatically charge your EV when prices are low on Octopus Agile. Learn more about the Ohme here.
  • Half hourly electricity prices that update daily based on the wholesale cost
  • Save money by moving your energy use outside peak demand hours of 4-7pm
  • This tariff means electricity prices change every half hour – sometimes they will be very low and other times higher
  • Good for those who want the cheapest rates across the day without waiting until midnight.
  • Works perfectly with the Ohme Intelligent Wall Charger, which will work with the agileOctopus tariff and automatically charge your car at the cheapest rates.
