EV vs petrol: total cost of ownership in 2026

Total cost of ownership for any car has five major components: purchase price (or finance cost), fuel/energy, servicing, insurance, and depreciation. EVs win or draw on most of these, but the picture varies sharply by country and by car class.

For this comparison we assume 14,000 km/year, a five-year ownership window, a typical mixed charging pattern (80% home off-peak / 20% rapid) for the EVs, and current 2026 fuel prices for the petrol equivalents (£1.45/L UK, €1.85/L France, €1.95/L Italy, AU$1.95/L Australia).

On a 14,000 km/year pattern, a Tesla Model 3 LR averages around 15 kWh/100 km. At our mixed home/rapid mix, that's roughly £370/year in the UK, €530/year in France, €620/year in Italy, and AU$510/year in Australia. A Volkswagen Golf 1.5 TSI at 6.5 L/100 km uses 910 L/year — roughly £1,320 UK, €1,684 France, €1,775 Italy, AU$1,775 Australia.

Over five years, the Model 3 saves £4,750 in the UK, €5,770 in France, €5,775 in Italy and AU$6,325 in Australia versus the Golf on fuel alone. The Kia EV6 vs Audi A4 numbers are broadly similar with a slightly larger absolute saving because the A4 burns more.

EVs have no oil, no spark plugs, no cambelt, no exhaust, no clutch, and brakes that wear glacially thanks to regenerative braking. Manufacturer service schedules reflect this — Tesla recommends inspections rather than fixed-interval services; Kia and Hyundai charge meaningfully less for EV service plans than ICE equivalents.

Typical 5-year servicing costs in 2026: Tesla Model 3 around £700 UK, €900 FR/IT, AU$950 AU. VW Golf around £1,800 UK, €2,300 FR/IT, AU$2,400 AU. Net EV saving of around £1,100 / €1,400 / AU$1,450 over five years.

EV insurance premiums are still settling out in 2026. Repair costs are higher (battery proximity, sensor complexity, fewer approved bodyshops) and theft rates on some popular EVs have spiked. Expect to pay 10-25% more to insure a Model 3 or EV6 than the petrol equivalent — roughly £150-300/year more in the UK, €120-250/year more in France/Italy, AU$200-400/year more in Australia.

Over five years, this typically erodes £750-£2,000 of the fuel saving. See our EV insurance guide for shop-around advice that can pull this number back.

EV residuals took a hammering in 2023-2024 and have stabilised through 2025 and into 2026. Current 5-year residuals on the comparison cars in this guide are roughly: Tesla Model 3 LR 45-50% of new price, Kia EV6 50-55%, VW Golf 1.5 TSI 50-55%, Audi A4 45-50%. Honours roughly even when measured in percentage terms.

In absolute money, the EV usually loses slightly more because the sticker price was higher, but the gap is much smaller than the 2024 panic suggested. Our EV resale value tool tracks the latest numbers.

UK: company car BiK rate of 3% in 2026/27 keeps EVs hugely attractive for salary-sacrifice schemes; private VED has been levelled to ICE equivalents from April 2025. France: bonus écologique is being scaled back but stays meaningful for sub-€47,000 EVs; lower TVS and free regional cards still apply. Italy: Ecobonus EV remains for sub-€35,000 cars; ZTL access in major cities is a non-cash benefit. Australia: federal FBT exemption on novated EV leases under the LCT threshold remains in place into 2026; state stamp duty and rego discounts vary.

These incentives can swing the comparison by £2,000-£5,000 over five years, especially for company-car buyers. See our EV incentives guide for the latest position.

Stacking it all together for a private UK buyer comparing a Tesla Model 3 LR against a VW Golf 1.5 TSI over five years and 70,000 km: fuel saves £4,750, servicing saves £1,100, insurance costs £1,250 more, depreciation costs roughly £9,700 more in absolute money. Headline: roughly £5,100 worse on TCO before incentives, equal-to-better after factoring in any company car or salary sacrifice scheme.

For company car drivers, the EV wins by a clear margin in every country we cover. For private buyers on retail finance, the picture is closer and depends heavily on incentives and the residual at the end of the deal.

The single biggest TCO swing factor isn't fuel or depreciation — it's how you bought the car. Company car / salary-sacrifice drivers in the UK pay tax on 3% of P11D value as Benefit-in-Kind for BEVs in 2026/27, compared to 30-37% for petrol equivalents. On a £45k Tesla Model 3 LR for a 40% taxpayer, that's roughly £540/year of BiK versus £6,750 for a petrol Audi A4 equivalent — a £6,200/year tax saving that dwarfs every other line in the comparison.

Australian novated-lease buyers under the LCT fuel-efficient threshold (~AU$91k) get the FBT exemption, which on a typical AU$70k EV salary-package deal saves AU$6,000-8,000/year of equivalent tax. French TVS reduction and Italian regional incentives are smaller but meaningful for company fleet.

Private retail buyers see none of this. The TCO comparison for a private cash buyer is genuinely close — BEV slightly behind on absolute money over five years, comfortably ahead if you have home off-peak charging and any state incentive. The honest answer to 'is an EV cheaper than petrol' depends almost entirely on which side of that company-car / private-buyer line you sit on.

Stretching the comparison out to 100,000 km (roughly seven years of typical UK use) sharpens the picture. EV fuel and servicing savings compound; depreciation flattens after year four; insurance gap closes as repair networks mature. By 100,000 km the BEV is usually comfortably ahead of the petrol equivalent in absolute money for a private buyer, before any incentive.

The crossover point — the kilometre at which cumulative EV ownership cost overtakes cumulative petrol cost in the buyer's favour — has moved earlier through 2025-26. For a Tesla Model 3 LR vs VW Golf 1.5 TSI it now sits around 55-65,000 km on a UK private buyer profile, down from 80-90,000 km in 2023.

Three line items rarely shown in marketing comparisons but worth real money over five years. Tyres: EVs wear them 15-25% faster due to weight and instant torque. Budget for one extra set of premium EV-rated tyres (~£600 in UK, ~AU$900 in Australia) over a five-year ownership window.

Home wallbox install: £800-£1,400 in UK, AU$1,200-2,000 in Australia. One-off, but a real cost in year zero. Pays back fast in saved public-charging fees but should be in the TCO. Battery health check on used purchase: £100-£200 from independent specialists (Cleevely EV, AVID, Aviloo). Worth doing on any used EV — quietly catches the small minority of cars with real degradation issues.

On the other side: EVs save on small items that add up — congestion charge exemptions (London ULEZ, Milan Area B, Paris Crit'Air 0), some toll discounts in Norway and parts of France, free or discounted parking in many Australian and Italian council areas. Worth £200-£1,000/year for urban-based drivers depending on city.
