  • May 26, 2023

If you charge an electric car at home, you can make big savings when you switch to the best EV tariff for your use. A simple EV tariff, like Octopus Go, typically saves a household a few hundred pounds each year. New, smarter EV tariffs, like Octopus Intelligent and OVO Charge Anytime, can mean cheaper charging and even bigger savings.

The best EV tariff depends on how much charging you do at home. It also depends on how much energy you use during the day and how much you could shift overnight. To explore what is best for you, try our free EV tariff and solar assessment tool.

More ways to save on charging at home

Once you’ve found the right EV tariff for your use, there are many more ways you can save with cleaner energy for your car and home. For instance, it’s cheaper than ever to install solar, or go a step further by selling energy back to the grid from a home battery.

Or how about owning a share in a wind farm or solar park, or getting rewarded for sharing your charger? Our free EV energy comparison helps you explore what works for your household.

What is an EV tariff?

Electric Vehicle (EV) tariffs basically offer cheap unit rates for overnight charging, usually in a four-hour period in the middle of the night. The drawback of these and other types of ‘time-of-use’ tariff are higher day-time energy costs and sometimes a higher daily standing charge. 

Which providers offer EV tariffs?

Octopus Energy offers many EV tariffs – Go (and Go Faster with a choice of time slots) and Intelligent. Octopus also has tariffs aimed at homes with solar and batteries (Flux) and heat pumps (Cosy). It also has a dynamically priced tariff, Agile, which offers prices that track the wholesale electricity price. OVO has an add-on for cheap flat-fee for EV charging. British Gas has relaunched its EV tariff and its rates are fairly competitive with Octopus and OVO. At the moment EDF hasn’t yet reintroduced its four ‘GoElectric’ tariffs. E.On Next and Scottish Power have yet to reenter the EV tariff market.

Is an EV tariff right for me?

This depends on how much energy you use during the day and how much charging and home energy use you could shift into the overnight window. EV tariffs might not offer the best value if you use lots of electricity in your home that you can’t realistically shift off-peak or if your driving patterns mean you aren’t doing much charging at home.

For many EV households though, an EV tariff could still be a good option. The more energy use you can shift overnight, the more you will save with an EV tariff. That doesn’t mean changing your waking hours, just think about timing an immersion heater, dishwasher or other energy hungry appliances to the off-peak window.

An EV tariff gives you a motive to avoid the energy ‘rush hour’, so it means you’ll be using less gas-powered energy and more lovely truly green electrons from renewable sources.

Tips on choosing a tariff

The first move, if you haven’t already got one, is to book a smart meter installation. If you aren’t ready to switch tariff yet, book this with your current supplier.

Some tariffs may offer ‘free miles’, but don’t forget that 2,000 miles is a discount of less than £10 per month. Check the rates they quote for electricity at any other time of the day, and the standing charge. Depending on all your normal home use you might end up paying more for that cheap overnight charging.

If there’s an offer of a free or discounted home charger installed at your home, check that the charger is right for you. For example, does it integrate with everything else in your home – like solar, or home assistants.

Who are the best energy providers for electric vehicle owners?

Octopus Energy has been hard to beat in terms of price and customer service for EV drivers. However, others like OVO and British Gas are starting to improve their game with tariffs that are competitive on price and offer more flexibility for EV charging and different home energy use patterns.

We’re expecting other tariffs to return to the market. Although limited in terms of compatible car and charger types, E.On Next had a super low off-peak rate and a clever app to help you keep on top of your charging costs and track the carbon intensity of your energy.

Big 6 providers have in the past made it very difficult to obtain a quote until you are already an energy customer.

How green are EV tariffs?

All EV energy tariffs in the UK guarantee 100% renewable energy, although the way in which they back this promise does vary. Read more on how green your ‘green’ energy really is for all our top tips on choosing a green energy supplier.

Can I use an Economy 7 meter to charge my EV?

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) 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 paying more on 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.

Green EV tariffs

Sometimes there’s even more you can do to save the planet and help your wallet. With record prices for energy, would solar pay? Does a home battery start to make sense? As well as finding the best EV tariff, our free EV charging and home energy assessment can show you how to squash your home’s energy carbon footprint and become more energy self-sufficient.
