Is an EV Really Cheaper to Run in the UK? A Full Cost Breakdown

Electric vehicles (EVs) are often hailed as the wallet-friendly, eco-warrior’s dream compared to petrol and diesel cars in the UK. But when you dig into the nitty-gritty costs—from purchase price to ongoing maintenance—is owning an EV really cheaper? Let’s take a joyride through the numbers with a full cost breakdown for 2025, so you can decide if an EV is the financially savvy choice or just a shiny new gadget to impress your neighbours.

Purchase Price: Sticker Shock vs. Battery Breakthroughs

First things first—getting behind the wheel of a new EV might require a slightly bigger handshake with your bank manager. The average price tag for a new EV in the UK stands at around £40,000, compared to about £30,000 for petrol or diesel cars. That’s quite the difference, unless you’re willing to lease or bet on battery tech continuing to drop in price faster than your morning toast burns.

Good news is, battery costs are steadily sliding downward, and more affordable EV options pop up each year. So don’t let the upfront sticker shock scare you off—there’s payback in the details.

Fuel and Energy Costs: Charging Your Car (and Your Wallet)

Here’s where EVs really start to flex their financial muscles. Charging an EV at home can set you back as little as 2p to 8p per mile during off-peak hours with smart tariffs. For a 60kWh battery that can cover around 200 miles, a full charge might cost about £8.40. Meanwhile, burning petrol or diesel for the same distance can cost you upwards of £28, often more.

While public rapid chargers tend to be pricier than a cosy home socket, they still usually beat petrol pumps in cost. So unless you enjoy the thrilling aroma of petrol stations, EVs are likely to keep more pounds in your pocket during your daily drives.

Maintenance: Fewer Moving Parts, Fewer Headaches

EVs are like the low-maintenance friends of the vehicle world—they skip the oil changes, wave goodbye to complex transmissions, and even wear their brake pads less thanks to regenerative braking.

Expect to spend about £235 a year on maintenance for an EV, while petrol or diesel cars hover around £400 annually. That’s almost like your car going on a diet and saving you some cash!

Insurance: A Pricey Peace of Mind

Here’s one area where EVs cause a little bit of sticker shock—insurance. With repairs on specialized parts like batteries often more expensive, average premiums for EVs come in at around £1,020 per year, compared to approximately £740 for petrol or diesel vehicles.

But before you call your insurance broker in despair, keep this in mind: as EVs become more mainstream and repair networks expand, those premiums are expected to mellow out like a good cheese.

Taxation: The Changing Landscape

Once upon a time, EVs lived a tax-free life in the UK. Good news for the green drivers—they now pay a modest £10 in the first year and £195 per year afterward from April 2025. This is still in the same ballpark as many petrol and diesel cars, especially the pricier models.

For the business crowd, running an EV is even sweeter: the Benefit-in-Kind (BIK) tax rate is just 3% in 2025/26, climbing gently to 5% in 2027/28—much kinder than the tax burden on petrol or diesel company cars. That could mean serious savings for company car drivers.

Government Incentives: Charging Up Your Savings

While direct purchase grants may have buzzed off for some EV models, the UK government still offers clever incentives to soften ownership costs:

• Up to £350 towards home charging point installation via the Electric Vehicle Homecharge Scheme.
• Workplace charging infrastructure grants.
• Support for on-street residential charging for those without private driveways (because who needs parking drama?).

These perks help electrify the appeal beyond just the price tag on the car itself.

So, Is an EV Really Cheaper to Run in the UK?

Summing it all up, despite a pricier dance card at purchase and a slightly heftier insurance bill, EVs generally deliver lower running costs in the UK. Your wallet will thank you most at the pump—or rather, the socket—where electricity tends to beat petrol and diesel hands down. Couple that with cheaper maintenance, tax benefits (especially for company car drivers), and government incentives, and the balance tips strongly in favour of going electric.

If you have a chance to charge at home, drive a typical amount of miles, and don’t mind shelling out a bit upfront, an EV is likely the more economical long-term partner on your journeys. Plus, the EV market is evolving faster than a squirrel on espresso—so keep an eye on prices and incentives, as changes could further sweeten the deal.
