The figures above show that most UK EV drivers pay significantly less to run their car than they would with petrol. The remainder of this guide unpacks each cost category in detail, explains what drives the variation, and shows you exactly where the savings come from.

How much does it cost to charge an EV at home?

Home charging is, for most EV owners, the dominant variable in their annual running cost, and also the one they have the most control over. Two rates matter here: the standard Ofgem price cap rate, and the dedicated off-peak EV tariff rate.

Ofgem cap rate (April–June 2026): 26.55p/kWh. This is the unit rate on the default standing tariff for direct-debit customers on a standard variable contract. A full charge of a 60kWh battery at this rate costs around £15.93. At a typical real-world efficiency of 3.5 miles per kWh, that equates to roughly 7.6p per mile.

Dedicated EV tariff off-peak rate: from around 7p/kWh. Several energy suppliers offer time-of-use tariffs specifically designed for EV owners, with cheap overnight windows typically running from 11pm to 6am or similar. At 7p/kWh, the same 60kWh charge costs just £4.20, and the cost per mile drops to around 2p. That is a saving of over 70% compared with charging at the standard cap rate.

The single biggest variable in EV running cost is your electricity tariff. Switching from the standard cap rate to a dedicated EV tariff can cut your annual charging bill by up to 74%. See our full EV tariff comparison for current rates and eligibility criteria.

For the annual sums: at 8,000 miles and 3.5 miles per kWh, you use around 2,286kWh per year. At 7p that is approximately £160. At 26.55p it rises to around £607. The difference of roughly £447 a year represents the maximum potential saving from switching to a dedicated tariff, and is the reason tariff choice sits at the top of any EV running cost guide.

Two further points are worth noting. First, most suppliers charge a standing charge on top of the unit rate, typically 50–60p per day on standard tariffs. This does not change with your driving habits. Second, battery efficiency drops in cold weather; a realistic winter efficiency figure might be closer to 2.8–3.0 miles per kWh rather than 3.5. For a detailed look at how cold weather affects range, see our guide to electric car cold weather range.

How much does public charging cost?

Public charging is a fact of life for most EV owners, whether for long journeys, top-ups at the workplace, or situations where home charging is not practical. It is also, on a per-mile basis, substantially more expensive than home charging.

According to Zapmap's network pricing data for April 2026, the weighted average cost across rapid and ultra-rapid public chargers (typically 50kW and above) is approximately 79p/kWh. Prices range from around 62p/kWh at the cheaper end of the top-10 networks to 92p/kWh at the pricier providers. At 79p/kWh and 3.5 miles per kWh efficiency, public rapid charging works out at roughly 22p per mile, compared with around 2p per mile on a home overnight tariff. That is an eleven-fold difference.

Slower destination chargers, such as those found at supermarket car parks, hotels, and leisure centres, often charge between 35p and 55p/kWh, or are sometimes provided free as a customer benefit. These represent better value than rapid chargers and are worth building into longer journeys where there is time to spare.

For budgeting purposes, most EV owners with home-charging access use public charging for approximately 10–20% of their total mileage, according to Zapmap's user data. At 8,000 miles per year with 15% charged publicly at 79p/kWh and 85% charged at home at 7p/kWh, the blended annual cost comes to approximately £365, compared with approximately £160 for home charging alone. The lesson is clear: reducing reliance on rapid public charging is one of the most effective ways to keep EV running costs down.

Cost per mile: EV vs petrol vs diesel

The cost-per-mile comparison is the most direct way to see how EV economics compare with internal combustion alternatives. The table below uses April 2026 fuel prices (RAC Fuel Watch: petrol 157p/litre, diesel 165p/litre) and assumes 3.5 miles per kWh for the EV.

To put this in annual terms: at 8,000 miles per year, a petrol driver at 15.7p per mile spends approximately £1,256 on fuel. An EV owner charging mostly at home on a 7p tariff spends around £160 — a saving of over £1,000 per year on energy alone.

Even at the Ofgem cap rate, the EV owner pays approximately £608 versus the petrol driver's £1,256 — still a saving of around £648 a year. Only when relying heavily on rapid public charging (22p/mile) does the EV become more expensive to run on an energy basis than a reasonably efficient petrol car.

The diesel case is closer, because modern diesels achieve better fuel efficiency than petrol equivalents. At 55 mpg and 165p/litre, a diesel costs around 13.6p per mile, versus 2p for a home-charging EV. The annual gap at 8,000 miles is still approximately £910 in the EV's favour when charging at home on an off-peak tariff.

Road tax (VED) for electric cars from April 2025

The road tax exemption that EVs previously enjoyed ended on 1 April 2025. All electric cars now pay Vehicle Excise Duty (VED), though the rates differ depending on when the vehicle was registered.

New EVs registered on or after 1 April 2025 pay a first-year rate of just £10 (compared with up to £2,745 for high-emission petrol and diesel cars), then move to the standard £195 rate from year two onwards.

EVs registered between 1 April 2017 and 31 March 2025 moved directly to the £195 standard rate from April 2025. There is no discounted first-year rate for this cohort.

EVs registered before 1 April 2017 fall into band B of the older VED system and pay £20 per year.

The Expensive Car Supplement (ECS) is an additional charge of £425 per year applied to vehicles with an original list price over £40,000. It applies from the second year of registration through to the sixth year, making the total annual VED bill £620 for affected owners (£195 + £425). The November 2025 Budget announced that the ECS threshold would be raised to £50,000 for zero-emission vehicles registered from 1 April 2025; verify the exact threshold and applicable dates on GOV.UK at the time of reading, as the rules are subject to change.

For most EV owners in compact or mid-range models priced below £40,000, the annual road tax bill is simply £195 — still significantly lower than the first-year rates paid by new petrol and diesel buyers, and broadly in line with the standard rate paid by most combustion-engine owners thereafter.

How much does EV insurance cost in the UK?

Insurance is the cost category where EVs most clearly lag behind petrol equivalents, and it is worth understanding why before drawing conclusions.

Average EV insurance premiums in 2026 range from approximately £650 to £1,400 per year, depending on vehicle value, driver profile, location, and insurer. According to both the Association of British Insurers (ABI Q1 2026) and the MoneySuperMarket EV Insurance Index 2026, premiums for like-for-like EV models run approximately 10–25% higher than equivalent petrol cars.

The gap exists for several structural reasons. Battery packs are expensive components to repair or replace, and even minor damage to the pack can trigger a write-off decision. Thatcham Research data shows that EV repair times are on average around 14% longer than for equivalent petrol cars, partly because specialist technicians and parts may need to be sourced from further afield. The result is higher labour costs and more days in hire cars, both of which feed into premium calculations.

That said, the gap is narrowing. As the EV fleet grows and insurers accumulate more claims data, actuarial models are becoming more precise and competitive pricing is appearing. Several insurers now offer EV-specific policies with battery cover and roadside charging assistance included as standard. Shopping around annually, rather than auto-renewing, is particularly important for EV owners given the pace of change in pricing across the market.

VED and insurance rules apply UK-wide, including Scotland. Scotland's different income tax bands do not affect either of these cost categories.

Servicing and maintenance

This is one area where EVs hold a genuine advantage. Because electric motors have far fewer moving parts than combustion engines, there is simply less to go wrong, and less that needs routine replacement.

A typical EV service costs around £150–£200 per year (Which? Car Survey 2025; Kwik Fit 2026 pricing). An equivalent petrol car typically costs £200–£280 for the same annual service schedule. The saving is modest in absolute terms, perhaps £50–£80 a year, but it compounds over time and the gap is wider for higher-mileage drivers.

Items that EV owners will never need to budget for include engine oil and filter changes, spark plug replacements, and cambelt or timing chain work. Brake pads and discs also last significantly longer on EVs, because regenerative braking captures kinetic energy to slow the car before the physical brakes are engaged. Many EV owners report going 60,000–80,000 miles before needing brake pad replacements that would be needed at 30,000–40,000 miles in a petrol car.

Items that do still require attention include tyres (discussed in the next section), coolant (the battery thermal management system uses coolant), cabin air filters, and annual battery health checks. Most manufacturers include the latter as part of their standard service schedule. Wiper blades, screen wash, and 12V auxiliary batteries are also standard consumables regardless of drivetrain.

Tyres: the hidden EV running cost

Tyre wear is one EV running cost that often surprises owners who have switched from petrol. Electric cars are heavier than their combustion counterparts, typically by 200–400kg, because of the battery pack. They also deliver instant torque from a standstill, which places greater stress on the contact patch at the front wheels under acceleration.

The result is that EV tyres wear approximately 20% faster than equivalent tyres on petrol cars, according to data from tyre manufacturers and fleet operators. A set of tyres that might last 35,000–40,000 miles on a petrol car may need replacing at 25,000–30,000 miles on an EV of similar size.

Budget around £500–£700 for a full set of four EV-rated tyres, depending on the wheel size of your vehicle. Larger SUVs and premium models will be at the top of that range or beyond. Annualised over a 30,000-mile replacement interval at 8,000 miles per year, that works out to roughly £133–£187 per year, with wider variation for high-mileage or high-performance drivers.

It is worth specifying tyres that are rated for EV use where possible. EV-rated tyres are engineered to handle the additional load and torque characteristics of electric drivetrains; using standard tyres can result in faster wear, increased road noise (EVs are quiet enough for tyre noise to become perceptible), and reduced range due to higher rolling resistance. The Michelin e.Primacy, Continental EcoContact 6, and Bridgestone Turanza Eco are among the options commonly recommended for EV fitment.

Depreciation

Depreciation is, for many drivers, the largest single cost of car ownership over a three-to-five-year period, and EV depreciation has had a turbulent few years.

Used EV values dipped sharply in 2024 as a wave of ex-lease stock hit the market alongside concerns about residual values, battery health, and the pace of charging infrastructure development. However, the market stabilised through 2025. According to cap hpi and the AutoTrader Retail Price Index (Q1 2026), three-year residual values for mainstream EVs have settled at approximately 45–55% of the original list price, broadly in line with petrol equivalents in the same size category. The 2024 dip is now widely characterised by analysts as market-specific rather than structural.

Factors that support stronger EV residuals include generous manufacturer warranties on the battery, the ongoing roll-out of rapid charging infrastructure, and growing consumer familiarity with electric motoring. Models with longer WLTP ranges, established brand reputations, and well-regarded software platforms tend to retain value better than less-known entrants.

One way to sidestep depreciation risk entirely is to lease rather than buy outright. With a personal or business lease, you hand the car back at the end of the contract and have no exposure to any change in residual values. For more on whether leasing makes financial sense for you, see our guide to leasing an electric car in the UK.

Five-year total cost of ownership: EV vs petrol

Annual running costs tell only part of the story. The full picture emerges when you look at total cost of ownership (TCO) over a typical five-year ownership period, factoring in purchase price, depreciation, fuel, road tax, insurance, and servicing.

The example below compares the MG4 SE 51kWh, one of the most popular affordable EVs in the UK, with the Vauxhall Corsa 1.2 100PS, a direct petrol competitor in the same market segment. Both vehicles are driven 8,000 miles per year, with a mixed 80/20 home-to-public charging split for the EV. Insurance is estimated at the mid-tier market average for each model based on 2026 ABI data.

Figures are illustrative estimates for comparison purposes. Depreciation estimated at 45% of original list price for both models after 5 years. Charging split assumed at 80% home (7p/kWh) and 20% public (79p/kWh). Petrol assumed at 157p/litre, 45 mpg. Insurance mid-market estimate. Verify all figures against current market data before making a financial decision.

The five-year total favours the petrol Corsa by approximately £4,775 in this example, driven primarily by the higher purchase price and greater estimated depreciation on the MG4. However, the annual running cost advantage for the EV is around £1,100 per year once fuel, servicing, and road tax are accounted for. If you are considering the MG4 over a longer ownership period, or if you can negotiate a better purchase price, the TCO crossover point shifts in the EV's favour.

It is also worth noting that the Electric Car Grant, where applicable, reduces the EV's purchase cost, and that some EV owners will benefit from employer salary sacrifice schemes or business cost allowances that do not appear in a straight consumer comparison. The picture also looks very different if you compare vehicles of a similar price point rather than models in different market positions.

How to cut your EV running costs

If you want to bring your annual EV running costs down to the lower end of the range outlined above, here are the seven most impactful steps you can take.

1. Switch to a dedicated EV tariff. This is the single highest-leverage action available to most EV owners. Moving from the standard Ofgem cap rate to a dedicated overnight tariff can cut your home charging bill by up to 74%. See our EV tariff comparison to find the best current rates for your usage pattern and supplier region.
2. Install a 7kW home charger. A dedicated home wallbox not only unlocks access to EV-specific tariffs (most require smart charger compatibility for scheduling), it also charges your car roughly six times faster than a three-pin plug. Browse home EV chargers to find the right unit for your property.
3. Charge to 80% for daily use. Manufacturers and battery engineers consistently recommend keeping your state of charge between 20% and 80% for day-to-day use. This preserves long-term battery capacity and reduces the risk of accelerated degradation at the top end of the charge curve. Reserve 100% charges for long journeys where you need the full range.
4. Use free destination chargers wherever possible. An increasing number of supermarkets, hotels, retail parks, and car parks offer free or low-cost charging as a customer benefit. Apps such as Zapmap and PlugShare let you plan routes around free charge points. Even adding 10–20 miles of free charge per week materially reduces your annual spend.
5. Add solar PV if your roof is suitable. Generating your own electricity and using it to charge your car during daylight hours can reduce your effective charging rate to near-zero marginal cost. Pairing solar with a smart charger and battery storage extends the benefit into evening hours. The economics depend on your roof orientation, local irradiance, and upfront installation cost, but many owners report payback periods of 5–8 years.
6. Compare insurance every year without exception. EV insurance pricing is still maturing rapidly as insurers gather claims data. Premium differences of 20–30% between providers are common for identical risk profiles. Set a renewal reminder and get at least three comparison quotes each year rather than accepting the renewal offer.
7. Check eligibility for grants. The UK Electric Car Grant (currently up to £3,750 off eligible models under £35,000) can significantly reduce your upfront cost. Workplace charging grants, home charger grants for renters and flat owners, and local authority EV schemes may also apply to your situation. See our guide to government grants for electric cars in the UK for a full breakdown.

Frequently asked questions

How much does it cost to charge an electric car at home in the UK?

At the Ofgem cap rate (26.55p/kWh from April 2026), a full 60kWh charge costs around £15.93. On a dedicated EV tariff with an off-peak rate of around 7p/kWh, the same charge costs around £4.20. At 3.5 miles per kWh efficiency, that works out at around 2p per mile on an overnight tariff versus 7.6p at the cap rate.

Do electric cars pay road tax in the UK?

Yes, since 1 April 2025. New EVs registered after that date pay £10 in year one, then £195 per year. EVs registered from April 2017 to March 2025 moved to the £195 standard rate from April 2025. EVs with an original list price over £40,000 also pay the Expensive Car Supplement — verify the current threshold on GOV.UK at time of reading.

Are electric cars cheaper to run than petrol?

Yes for most UK drivers. Charging at home on a 7p/kWh off-peak tariff costs around 2p per mile. A 45 mpg petrol car at 157p/litre costs around 15.7p per mile, around eight times more. Annual servicing is also typically £50–£80 cheaper. The main cost gap versus petrol is insurance, which runs 10–25% higher for EVs.

How much more is EV insurance than petrol insurance?

Typically 10–25% higher on average in 2026 (MoneySuperMarket EV Insurance Index; ABI Q1 2026). Reasons include higher battery repair costs, longer repair times, and specialist parts. The gap is narrowing as insurers accumulate more EV claims data. Shopping around annually is particularly worthwhile for EV owners.

How long do EV batteries last and what does replacement cost?

Most manufacturers warrant EV batteries for 8 years or 100,000 miles. Capacity retention of 70% or above is the typical threshold. Full battery replacement, where needed, costs roughly £5,000–£15,000 depending on the vehicle (Thatcham Research). The vast majority of EV owners never need a replacement within normal ownership periods.
