For years, electric cars have enjoyed a near-mythical status in the cost-of-ownership conversation. Cheap to run, cheap to tax, and—if you played the charging game right—almost smugly inexpensive per mile. That advantage is about to shrink.

From April 2028, the UK government plans to introduce a pay-per-mile road tax for electrified vehicles, officially known as eVED (Electric Vehicle Excise Duty). In simple terms, it means EV and plug-in hybrid drivers will start paying for how far they drive, not just what they drive. In practice, it could add £200–£300 a year to the cost of running an electric car—and that’s before standard road tax is factored in.

This isn’t just a new line item on a spreadsheet. It’s a philosophical shift in how EVs are taxed, and one that arrives at a delicate moment in Britain’s electric transition.

How It Works (At Least on Paper)

Under current proposals, fully electric cars will be charged three pence per mile, while plug-in hybrids will pay one and a half pence per mile. Both rates will rise annually in line with inflation. The charge sits on top of regular Vehicle Excise Duty, which currently stands at £195 per year and is unlikely to be frozen until 2028.

Mileage won’t be tracked digitally. Instead, odometer readings will be logged annually—via the MoT for cars over three years old, or through accredited mileage checks for newer vehicles. Once a year, drivers will log into the DVLA system, estimate their annual mileage (much like an insurance declaration), and choose whether to pay in one go or spread the cost over 12 months. Drive more than expected? You’ll get a bill. Drive less? A rebate lands back in your account.

Simple, relatively low-tech, and deliberately light on surveillance. The downside is equally simple: you pay for every mile, including those driven outside the UK.

EVs vs ICE: The Numbers Still Favour Electric—For Now

One of the strongest arguments for EVs has always been running costs, and eVED doesn’t completely undo that. But it does blur the lines.

Take a Volkswagen Golf and its electric cousin, the ID.3. Charged at home on an off-peak tariff—around eight pence per kWh—the ID.3 works out at roughly two pence per mile for electricity, plus three pence per mile in tax. That’s still comfortably cheaper than a petrol Golf at roughly 12 pence per mile, or a diesel at around 10 pence.

The picture changes quickly, though. Charge at the energy price cap of 26p per kWh, and the ID.3 climbs to around nine pence per mile all-in, effectively matching the cost of running an ICE Golf. Rely on public rapid charging at up to 90p per kWh, and the electric option becomes decisively more expensive per mile than petrol.

The conclusion is unavoidable: where and how you charge now matters more than ever. The mileage tax doesn’t kill the EV cost advantage, but it makes it fragile.

Why the Government Is Doing This

The motivation isn’t subtle. As fuel duty revenue collapses with the rise of EVs, the Treasury is staring at a growing hole in the public finances. According to the Office for Budget Responsibility, eVED could raise up to £1.4 billion per year by 2029–30.

But there’s a catch. The same OBR estimates that by 2031, around 440,000 fewer EVs will be sold than would otherwise have been the case, as buyers react to higher ownership costs. That’s a remarkable admission: the tax raises money, but actively slows adoption.

Which leads to the central question—is this the right tax at the wrong time?

Industry Pushback—and Consumer Doubt

Reaction has been predictably mixed. A survey of readers found 37 percent consider the charge fair, while 23 percent see it as an unjust penalty on EV drivers. Another 32 percent believe it’s poorly timed and risks stalling momentum just as EVs approach the mainstream.

Industry voices have been sharper. Ford UK described the policy as “a confusing message at a critical moment,” warning that investment in charging and purchase incentives can’t offset the damage of a new usage tax. Charging providers echo that concern, arguing that reduced EV uptake weakens the business case for expanding rapid-charging networks—exactly the infrastructure the transition depends on.

Even organisations broadly supportive of fair road pricing, like the AA, stress the need for safeguards. Rural drivers, carers, and others who depend heavily on their cars could be disproportionately affected by a flat per-mile charge.

A Transition at a Crossroads

The government has attempted some damage control. From April 2026, the Expensive Vehicle Supplement threshold for EVs will rise to £50,000, easing the blow for higher-end electric cars. It helps—but it doesn’t change the broader message.

For the first time, EVs are being treated not as a special case, but as just another way of moving down the road. In one sense, that’s a sign of maturity. In another, it risks undermining the very incentives that helped electric cars gain traction in the first place.

Come 2028, the honeymoon is officially over. Electric cars will still make sense—often financial sense—but no longer by default. Every mile will count, literally. And for a government betting heavily on electrification targets, that may prove to be a risky recalculation.
