Electric Car Running Costs UK (2026): The Real Numbers

Key takeaway: Electric cars are significantly cheaper to fuel than petrol or diesel cars (roughly 4p to 7p per mile vs 14p to 18p per mile for petrol), but higher insurance premiums, faster depreciation on some models, and the upfront purchase price mean the total cost of ownership picture is more nuanced than the headlines suggest. For high-mileage drivers (12,000+ miles per year) who can charge at home, an EV is almost certainly cheaper overall. For low-mileage drivers relying on public chargers, the savings narrow considerably.

Electric car sales in the UK have grown rapidly. As of early 2026, pure battery electric vehicles (BEVs) account for roughly 20% of new car sales and the used EV market is expanding fast as leased vehicles return. But the running cost question remains the most common concern for potential buyers.

This guide breaks down every running cost category with real 2026 UK figures, so you can make an informed decision. You can check the running costs of any specific car (electric, petrol, or diesel) using our free car check tool.

Charging Costs: Home vs Public

Charging is the EV equivalent of filling up with petrol. The cost depends entirely on where you charge:

A typical EV consumes 3 to 4 miles per kWh (or 25 to 35 kWh per 100 miles). Smaller, more efficient cars like the MG4 and Tesla Model 3 are closer to 3.5 to 4 miles per kWh. Larger SUVs like the Tesla Model X or BMW iX are closer to 2.5 to 3 miles per kWh.

Public Charging

Public charging is more expensive and varies widely by network:

Charger Type	Typical Cost per kWh	Cost per Mile	Cost per 10,000 Miles
Slow (7kW, destination)	30-45p	8-12p	£800-£1,200
Fast (50kW, most common)	50-65p	13-18p	£1,300-£1,800
Ultra-rapid (150kW+)	65-85p	17-24p	£1,700-£2,400

At ultra-rapid charger prices, an EV costs roughly the same per mile as a petrol car. The financial case for an EV relies heavily on home or workplace charging. If you cannot charge at home or work, the savings are much smaller.

Insurance Costs: The EV Premium

Electric cars are consistently more expensive to insure than equivalent petrol cars. The reasons are straightforward: battery replacement costs are extreme (£5,000 to £20,000+), specialist repair facilities are still limited, and repair times are longer because fewer mechanics are trained on EV systems.

Car	Insurance Group	Typical Premium (30yr, 5yr NCB)
MG4 Standard Range	18-22	£550-£800
Tesla Model 3	48-50	£900-£1,400
Nissan Leaf (40kWh)	16-21	£480-£700
BMW i4	41-49	£800-£1,300
VW ID.3	22-28	£550-£850

For comparison, a Ford Fiesta 1.0 EcoBoost sits in insurance groups 7 to 14 (typical premium £350 to £550 for the same driver). A Tesla Model 3 at group 48 to 50 costs roughly double to insure. This is a significant ongoing cost that narrows the fuel savings.

Road Tax (VED): EVs Now Pay Too

Since 1 April 2025, electric cars pay road tax. An EV first registered from 1 April 2017 pays the standard rate of £200 a year (a brand-new EV pays £10 for its first year). EVs registered between March 2001 and March 2017 pay the Band A rate of £20 a year. EVs registered from 1 April 2025 with a list price over £50,000 also pay the "expensive car supplement" of £440 a year for five years, starting from the second time the car is taxed, bringing the total to £640 a year. EVs registered before 1 April 2025 do not pay the supplement.

This is a significant change. If you are buying a used EV, factor in £200 a year for most cars registered since April 2017, or £640 a year for a newer EV that cost over £50,000.

Servicing and Maintenance

EVs have fewer moving parts than combustion engines: no oil changes, no spark plugs, no exhaust system, no clutch (in most cases), and no timing belt or chain. This translates to lower servicing costs:

Item	EV Cost	Petrol Car Cost
Annual service	£80-£150	£150-£300
Brake pads (lifetime)	100,000+ miles (regen braking)	25,000-40,000 miles
Tyres	£100-£200 each (heavier cars = faster wear)	£60-£150 each
Coolant system	Battery cooling check at service	Flush every 3-5 years (£80-£120)
12V battery	Replacement every 4-6 years (£80-£150)	Same

EVs save roughly £200 to £400 per year on servicing and maintenance compared to petrol equivalents. However, tyre wear is faster on EVs due to their heavier weight and instant torque, which partially offsets the savings.

MOT: electric cars need an MOT on the same schedule as any other car, from three years old. In 2025, 13.4% of electric cars failed their first MOT at the first attempt, against 10.3% of petrol cars, and they still failed about 12% more often than petrol cars with the same mileage. See our electric car MOT failure rates study for every fuel type and electric model.

Total Cost of Ownership: EV vs Petrol (10,000 Miles/Year)

Here is a realistic annual running cost comparison for a typical mid-range car, assuming home charging for the EV:

Cost Category	EV (e.g. MG4)	Petrol (e.g. Ford Focus 1.0)
Fuel / Charging	£350 (off-peak)	£1,400
Insurance	£650	£450
Road Tax	£200	£200
Servicing	£120	£250
Tyres	£200	£150
Total	£1,520	£2,450

On these numbers, the EV saves approximately £930 per year in running costs. Over 5 years, that is about £4,650. Whether this offsets the higher purchase price depends on the specific cars being compared and how depreciation plays out.

Depreciation: The Hidden Variable

Depreciation is the largest single cost of car ownership, and it is where EVs have historically struggled. Battery technology evolves rapidly, and a 3-year-old EV with 200 miles of range looks less attractive when new models offer 300+ miles. However, the used EV market is maturing and depreciation curves are stabilising.

Tesla Model 3s hold their value better than most EVs (roughly 55% to 60% after 3 years). Budget EVs like the MG4 and BYD Atto 3 depreciate faster (roughly 45% to 50% after 3 years) because new prices keep falling. Premium EVs (BMW i4, Mercedes EQC) depreciate aggressively (40% to 45% after 3 years) because the technology ages quickly relative to new models.

Should You Buy an EV in 2026?

An EV makes financial sense if:

• You can charge at home or work (ideally on a cheap overnight tariff)
• You drive 10,000+ miles per year (more miles = more fuel savings)
• You plan to keep the car for 3+ years (to offset the purchase premium)
• You do not need to make regular long journeys without reliable charging stops

An EV may NOT save you money if:

• You rely entirely on public rapid chargers
• You drive fewer than 6,000 miles per year (fuel savings are too small to offset higher insurance)
• You change cars every 1 to 2 years (depreciation may work against you)
• You are comparing against a very efficient petrol hybrid (e.g. Toyota Yaris Hybrid)
