Are Electric Vehicles Cheaper To Run? 2025 Guide

Electric vehicles (EVs) promise lower running costs compared to petrol or diesel cars, primarily through cheaper energy and reduced maintenance. However, factors like higher upfront prices, insurance, taxes, and charging access can influence overall affordability. Recent studies show EVs often save owners thousands over 3-5 years, especially with home charging, but results vary by model, mileage, and location.

Energy Costs: The Biggest EV Advantage

Charging an EV at home is significantly less expensive than fueling a comparable petrol car. For instance, powering a Volkswagen ID.3 for 36,000 miles costs around £1,562, compared to £3,900 for a petrol Golf over the same distance—less than half the price. Similarly, a Vauxhall Corsa Electric incurs about 70% lower energy costs than its petrol counterpart.

A 2025 study by ElectricVehicles.uk across 50 EV models found new EV owners save an average of £7,785 over four years versus petrol equivalents, equating to roughly £2,000 annually. This relies heavily on home wallbox charging, where 97% of scenarios showed savings. Without home access, savings drop: 60% for 5,000 miles/year and 46% for over 10,000 miles.

Public charging is costlier but still competitive. Energy costs per mile for EVs average 4-6p at home, versus 15-20p for petrol at current UK prices. Over time, as electricity tariffs stabilize and fuel prices fluctuate, this gap widens in EVs’ favor.

Maintenance and Servicing Savings

EVs have fewer moving parts—no engine oil changes, timing belts, or complex transmissions—leading to lower servicing needs. A Skoda Elroq requires service every two years, totaling £200+ less over three years than a petrol Karoq. Toyota’s bZ4X servicing is about 30% cheaper than similar petrol SUVs, with fixed plans at £6+ per month.

Regenerative braking reduces wear on pads and discs, further cutting costs. Annual maintenance for EVs typically runs £200-300 less than ICE vehicles. Battery warranties (often 8 years/100,000 miles) provide peace of mind, minimizing unexpected repairs.

Taxation and Road Fees for EVs

EVs no longer fully escape Vehicle Excise Duty (VED); post-2025, owners pay a minimum £390 over three years, aligning with petrol cars. However, zero-emission incentives persist in some regions, though UK changes have narrowed the gap.

Company car tax remains lower for EVs (2% Benefit-in-Kind rate vs. 20-37% for petrol), benefiting fleet users. Salary sacrifice schemes amplify savings, but private owners face parity in VED.

Insurance Premiums: A Potential Drawback

EV insurance often exceeds petrol equivalents due to higher repair costs, specialized parts, and battery replacement risks. In comparisons, EVs like the ID.3 show £1,162 over three years versus lower for petrol Golfs. Newer models with advanced safety tech may close this gap over time.

Tyre Wear and Replacement Costs

EVs’ instant torque accelerates tyre wear, increasing costs. Higher vehicle weights (batteries add 200-500kg) compound this. Over 36,000 miles, tyres for an ID.3 cost £604, comparable to petrol but pricier per mile for some models. Low-rolling-resistance tyres optimized for EVs help mitigate.

Total Cost of Ownership Breakdown

Whole-life costs over three years/36,000 miles reveal nuances. The table below compares select models (excl. purchase price and depreciation):

Notes: Figures approximated from recent analyses; Skoda Elroq saves ~£5,000 over Karoq. EVs win on energy/servicing but lag in depreciation/insurance. Used EVs save £3,440 over five years, with 80% cheaper upfront.

New vs. Used EVs: Ownership Scenarios

New EVs shine in four-year leases/PCP, with £7,785 average savings. Used models (35 analyzed) offer upfront affordability but smaller £3,440 savings over five years—still positive for home chargers (£5,000+). High-mileage public chargers see diminished benefits.

Energy Innovation research confirms most US EVs are cheaper to own off-lot, a trend extending to UK with falling prices.

Depreciation and Upfront Costs

EVs depreciate faster initially due to tech evolution, impacting resale. ID.3 loses £21,336 over three years vs. Golf’s £18,500. Newer, longer-range models like Elroq buck this, matching or undercutting petrol TCO.

Future Trends Influencing EV Costs

Falling battery prices, expanded charging networks, and policy shifts (e.g., ZEV mandate) will enhance affordability. By 2026, expect tighter insurance and even lower energy via smart tariffs. Petrol prices volatility favors EVs long-term.

Who Benefits Most from EV Savings?

• Home chargers: Maximum savings (£2,000+/year).
• Low-mileage drivers: <10,000 miles/year amplifies advantages.
• Fleet/business users: Tax perks dominate.
• High-mileage/public chargers: Marginal or no savings.

97% of home-charging new EV owners save vs. petrol.

FAQs

Is charging an EV cheaper than petrol?

Yes, home charging costs half or less per mile; e.g., ID.3 at £1,562 vs. Golf £3,900 for 36,000 miles.

Do EVs have lower maintenance?

Yes, 20-30% less due to simpler design; e.g., Elroq £200 cheaper over three years.

Are EV taxes the same as petrol now?

Yes, VED £390/3 years for both post-2025.

What’s the average EV saving over 4 years?

£7,785 for new models with home charging.

Are used EVs cheaper to run?

Yes, £3,440 average over five years, especially if home-charged.

Conclusion: EVs Often Cheaper, But Not Always

EVs deliver substantial savings on energy and maintenance, often totaling thousands over ownership, but higher insurance, tyres, and depreciation can offset for some. Home charging is key; models like Skoda Elroq prove competitive TCO. As infrastructure improves, EVs edge ahead.
