An electric car does not have one standard annual running cost. The biggest variable is usually how and where you charge: home charging on an off-peak tariff can be inexpensive, while frequent public fast charging can sharply increase energy costs. To estimate your own total, combine your car’s real-world efficiency and annual mileage with your charging mix, then add model- and driver-specific insurance, maintenance and applicable vehicle taxes.
What counts as an electric car’s running cost?
Running costs are the recurring expenses of using a car: electricity or fuel, maintenance and repairs, insurance, and vehicle taxes. They are not the same as total cost of ownership. A full ownership comparison also includes the price you pay for the car, finance costs, depreciation, any home chargepoint installation and the amount you may recover when you sell it.

That distinction matters because a lower energy bill does not automatically make an EV cheaper overall. The result depends on the driver, vehicle, annual mileage, electricity tariff, proportion of public charging, insurance quote, tax eligibility and how long the car is kept. Compare the same mileage and ownership period for both vehicles, and make clear which costs are included in any headline figure.
How much does charging an EV cost?
Use your car’s efficiency and your electricity rates rather than battery size alone. Battery capacity helps estimate the energy needed for a full charge; efficiency tells you how much electricity the car uses to cover a given distance. The basic estimate is:

Annual home-charging cost = annual miles ÷ miles per kWh × electricity price per kWh.
For a mixed charging pattern, calculate the home, public slow and public fast portions separately, using the price that applies to each, then add them together. If your efficiency figure is expressed in kWh per 100 miles or per 100 kilometres, convert it to the same distance unit as your annual mileage before calculating. Use a realistic efficiency estimate for the conditions you drive in; an advertised laboratory range is not a guarantee of the distance you will get between charges.
Home charging and off-peak tariffs
Charging at home can cost less when you have off-street parking, a suitable chargepoint and a tariff with a lower overnight rate. Whether the tariff saves you money depends on its time window, eligibility rules and any other costs, as well as how much charging you can shift into that window. Compare the rate you can actually use with your current electricity price; do not assume every household can access the same EV tariff.

A UK government campaign illustration published in 2026 shows why assumptions matter. It estimates a full charge at £4.38 for a particular high-selling example vehicle using an 8p-per-kWh tariff available in April 2026. That car’s stated laboratory range is 259 miles and its stated consumption is 13.1kWh per 62 miles. In a separate journey illustration, the campaign applies a 24% adjustment to the laboratory range, producing a modeled 177-mile real-world journey. The £4.38 charge figure is an example based on its stated car and tariff, not a price promise for another EV or a guarantee of real-world range.
With a home charger, check compatibility with the car and electrical setup, charger power, installation requirements, warranty and total installed cost. Installation is a possible ownership cost, not part of the electricity price per mile. If you cannot charge at home, do not use a home-tariff example as your expected cost: calculate from the public prices and charging locations you will actually rely on.
Public slow and fast charging
Public charging can make a substantial difference to the energy bill. In its 2026 international analysis, the International Energy Agency found public slow charging could cost up to 150% more than residential electricity and public fast charging up to 240% more. It also concluded that relying exclusively on public fast charging could make EV running costs higher than those of a gasoline car. These are maximum premiums in an international analysis, not a price list for every UK network or a prediction for an individual route; local prices, vehicle efficiency and charging habits change the comparison.

HMRC’s advisory electric rates, effective from 1 September 2026, are 7p per mile for home charging and 15p per mile for public charging in the relevant company-car expenses context. HMRC calculates these rates using vehicle electricity consumption and electricity-price data, including public slow- and fast-charging price-index data. They are advisory rates for that expenses purpose, not the retail price at a charger, a household tariff or a personalized estimate of your cost per mile.
What does a modeled annual saving tell you?
The same UK government campaign presents a scenario with annual mileage of 10,000 miles. Its assumptions include EV consumption of 18.5kWh per 100km, petrol consumption of 8L per 100km, EV-specific off-peak electricity at 7.5p per kWh based on a sample intended to represent average 2025 home tariffs, and petrol at 143p per litre based on 2025 Department for Energy Security and Net Zero weekly prices. It also includes annual combined insurance-and-maintenance estimates of £1,680 for the EV and £1,490 for the petrol comparator.
| Modeled item | EV | Petrol comparator |
|---|---|---|
| Annual running cost in the campaign scenario | £1,902 | £3,320 |
| Difference under those assumptions | £1,420 lower modeled annual cost for the EV | |
| Combined annual insurance and maintenance estimate | £1,680 | £1,490 |
The model’s £1,420 difference is the arithmetic result of its assumptions; campaign messaging describes savings of up to £1,400 a year. These are modeled running costs, not current average household bills or a guaranteed saving. In particular, the combined insurance-and-maintenance estimates were developed by Element Energy for work last commissioned by the Department for Transport in 2021. The comparison does not give an insurance-only premium, and it excludes home charger installation. If your charging is mostly public, your mileage differs, or your actual quote and servicing costs are different, your result can change materially.

Maintenance and repairs: where an EV may differ
UK government guidance says EVs are cheaper to run in many cases and cites lower maintenance and repair costs. That is a qualified general finding, not a promise that every service visit or repair will cost less than for a petrol or diesel car. The cost for a particular vehicle depends on its model, age, condition, warranty and repair needs.
When comparing two cars, request or check the scheduled service plan for each exact model and include routine servicing, tyres, brakes, other consumables and likely repairs in your budget. Do not leave unexpected repairs out simply because a car is electric, and check which components or work the vehicle’s warranty covers, for how long and subject to what conditions. The available government comparison does not establish model-by-model prices for those items, so use manufacturer or repairer information for the cars you are considering rather than treating a general claim as a quote.
Insurance: get a quote for the actual car and driver
There is no universal EV insurance premium established by the available UK government figures. Insurance depends on the specific car and driver, so obtain a quote using the exact registration or model, postcode, annual mileage, intended use and driver details before deciding. For a useful comparison with a petrol or diesel car, request quotes for both using the same driver, cover assumptions and use.

The government campaign’s £1,680 EV and £1,490 petrol figures are combined annual insurance-and-maintenance estimates, not insurance-only prices. They were developed from Department for Transport-commissioned work last commissioned in 2021; they should not be presented as current premiums or as representative of every household. Keep insurance separate from maintenance in your own budget wherever your quotes and records allow, so you can see which cost is driving the difference.
Vehicle tax: separate today’s VED from announced future eVED
UK vehicle tax rules for EVs have changed and are scheduled to change again. Check the current GOV.UK vehicle tax tables for the relevant registration date and vehicle before budgeting. An April 2025 government guidance snapshot described a £10 first-year VED rate for EVs and company-car benefit-in-kind rates of 3%, rising by one percentage point each year to 5% in April 2028. Those dated figures should not be treated as a current tax quote: applicable VED and benefit-in-kind rates depend on the rules and circumstances in force.
Expensive Car Supplement threshold
Budget 2025 announced that from 1 April 2026 the VED Expensive Car Supplement threshold for zero-emission vehicles would rise from £40,000 to £50,000. The announcement applies to relevant zero-emission vehicles registered from 1 April 2025. If you are considering a higher-priced EV, check the current official rules and the vehicle’s registration and eligibility details; the purchase price alone may not settle the tax treatment.

HM Treasury’s Budget 2025 policy, restated in its 2026 consultation response, plans to introduce electric vehicle excise duty (eVED) from April 2028 alongside VED. The announced rates are 3p per mile for electric cars and 1.5p per mile for plug-in hybrids. Budget 2025 estimated that an average EV driver would pay around £240 a year under its assumptions. That official estimate is not interchangeable with multiplying a different driver’s mileage by the announced rate: at 10,000 miles, 3p per mile is arithmetically £300, but scheme details, mileage assumptions and any exemptions affect what an individual would owe. The announced start date is in the future; do not add eVED to a bill as though it is payable today.
How to compare your EV with another car
- Set the comparison. Use the same UK location, annual mileage and ownership period for the EV and the petrol or diesel alternative. Decide whether you are comparing running costs only or total ownership cost.
- Estimate energy separately. Use each vehicle’s realistic consumption and the prices you can access. Split EV mileage among home off-peak, other home and public slow or fast charging where relevant; use fuel consumption and a current local fuel price for the other car.
- Use real insurance quotes. Quote the exact vehicles for the same driver, postcode, annual mileage and type of use. Keep each quote’s cover assumptions consistent.
- Check maintenance and repair costs. Compare the service schedules, warranty terms, tyres, brakes, consumables and model-specific repair information. Treat unpriced items as unknown until you have a reliable estimate rather than assuming they cost the same.
- Apply the right tax rules. Check VED for the vehicle’s registration and current rules; consider company-car benefit-in-kind tax if relevant. For vehicles that may meet the Expensive Car Supplement criteria, check its threshold and eligibility. Keep the planned 2028 eVED separate from current charges.
- Add ownership costs only for a full comparison. Include purchase price or finance, depreciation, any home chargepoint installation and expected resale value over the same period. State clearly whether these are included in the result.
This method avoids a common false comparison: setting an EV’s home off-peak electricity against a petrol car’s fuel cost while leaving out the EV’s public charging, insurance or tax. The result is only as useful as the assumptions you can support, so keep them visible beside any total.
Quick Recap
Common estimating mistakes
- Using battery capacity as the whole cost calculation. Capacity indicates approximate energy for a full charge, but price per mile also depends on efficiency and the electricity rate.
- Assuming a laboratory range is the distance available in everyday driving. The 2026 campaign example applies a 24% adjustment to its stated laboratory range for one modeled journey; that is an illustration, not a universal adjustment for every car or driver.
- Treating an advisory rate as a tariff. HMRC’s September 2026 per-mile rates serve a company-car expenses purpose; your actual charging bill depends on the prices and charging locations you use.
- Applying a modeled saving to a different charging mix. The campaign’s scenario uses specified off-peak electricity, fuel prices, consumption, mileage and dated combined insurance-and-maintenance estimates. Change those inputs and the outcome changes.
- Combining running cost and ownership cost without saying so. Energy, insurance, maintenance and tax do not include purchase, finance, depreciation or installation unless the comparison explicitly adds them.
