The real cost of going electric in 2026 — and why it’s often less than people think

“Electric cars are too expensive.” It’s the most common objection we hear — and it’s increasingly out of date.

The upfront price of EVs remains higher than equivalent petrol or diesel models in many cases. But the total cost of ownership — what it actually costs to run a car over three or four years — tells a very different story for a growing number of drivers.

Here’s an honest look at the numbers.

Purchase price: the gap is closing

The sticker price premium for EVs has been narrowing. Between increased production scale, new entrants to the market, and competitive pressure from Chinese manufacturers now operating in Europe, the price gap between electric and combustion vehicles in the mid-range has reduced significantly.

At the volume end of the market — the cars most people actually drive — fully electric options are now available at comparable or lower price points than their petrol equivalents, even more so when you factor in the tax position if you’re a company car or salary sacrifice driver.

Fuel costs: electric wins clearly

Charging at home on a standard tariff costs a fraction of what equivalent petrol or diesel mileage costs. The exact saving depends on your electricity tariff and how you drive, but a rough rule of thumb for a typical family car doing 10,000 miles per year:

• 
  Petrol: approximately £1,400–£1,800/year in fuel
• 
  Electric (home charging): approximately £400–£600/year

That’s a saving of roughly £1,000 per year from fuel alone, before you factor in any other running costs.

If you have access to an EV-specific tariff or solar panels, the saving is larger again.

Servicing: fewer moving parts means lower bills

Electric motors have dramatically fewer components than internal combustion engines. No oil changes, no exhaust system, no timing belt, fewer brake replacements (thanks to regenerative braking). Independent servicing data consistently shows EVs cost less to maintain over time.

The main exception is tyres — EVs are heavier and produce instant torque, which tends to accelerate tyre wear. Worth building into your budget.

The tax position in 2026/27

This is where EVs genuinely pull ahead for company car drivers and salary sacrifice users.

The Benefit in Kind (BiK) rate for fully electric cars is 4% in 2026/27. For a 40% taxpayer driving a £50,000 EV, the annual tax liability is just £800. The same value petrol car at a 30% BiK rate would cost that driver £6,000 in tax per year.

For businesses, the employer National Insurance saving on salary sacrifice (at 15%) combined with the low BiK rate makes the electric salary sacrifice proposition genuinely compelling — often the cheapest way for an employee to drive a new car.

The honest caveats

We’re not here to oversell electrification. A few things are genuinely less convenient about EVs right now:

• 
  Public charging infrastructure is improving but inconsistent. If you regularly travel to areas with poor coverage, or don’t have home charging, range anxiety remains a real consideration.
• 
  Long journeys take more planning than with petrol. A 350-mile motorway trip requires a stop at a rapid charger. That’s fine if you plan for it, but different to filling up in five minutes.
• 
  Residual values remain less predictable than petrol equivalents in some segments, which matters if you’re buying outright or on PCP.

None of these are insurmountable, but they’re worth weighing honestly against the running cost savings.

The overall picture

For most drivers doing regular, predictable mileage with access to home charging, the total cost of running an EV over three to four years is lower than an equivalent petrol car. The upfront premium, where it still exists, is typically recovered through fuel savings within two years.

For salary sacrifice drivers, the economics are even more compelling — the combination of pre-tax salary sacrifice, low BiK, and lower running costs makes a new EV genuinely affordable in a way that simply wasn’t true five years ago.
