As electric vehicles (EVs) continue to grow in popularity across the UK, more drivers and businesses are asking the same question: are electric cars cheaper to run than petrol or diesel vehicles?
While electric cars often come with a higher purchase price, their day-to-day running costs can be significantly lower. From reduced fuel expenses to lower maintenance requirements, EVs can offer substantial long-term savings. However, it's also important to understand the hidden costs of owning an electric car before making the switch.
In this guide, we'll break down electric car running costs in 2026, compare them with traditional vehicles, and explore the factors that influence the overall cost to run an electric car.
How much does it cost to run an electric car?
One of the biggest advantages of EV ownership is the lower cost of energy compared to petrol or diesel.
The exact cost to run an electric car depends on several factors, including:
The vehicle's efficiency.
Electricity prices.
Charging location.
Annual mileage.
Driving style.
Generally speaking, charging an electric car at home remains the most cost-effective option. Drivers who rely heavily on rapid public charging may see higher costs, although EVs are often still cheaper to run than equivalent petrol or diesel models.
Typical running cost comparison
Vehicle Type | Approximate Cost Per Mile |
|---|---|
Petrol Car | Higher |
Diesel Car | Higher |
Electric Car (Home Charging) | Lower |
Electric Car (Public Charging) | Moderate |
While electricity prices can fluctuate, many drivers find that the overall electric car running cost remains lower than the equivalent fuel spend for an internal combustion engine vehicle.
Are electric cars cheaper to run than petrol or diesel cars?
In many cases, yes.
When comparing EV running costs against petrol and diesel vehicles, several factors work in favour of electric cars.
Lower energy costs
Electricity is typically cheaper than petrol or diesel on a cost-per-mile basis, especially when charging at home or using workplace charging facilities.
Reduced maintenance requirements
Electric vehicles have fewer moving parts than conventional vehicles. This means fewer components that can wear out or require replacement over time.
Potential tax benefits
Businesses operating electric vehicles may benefit from lower Benefit-in-Kind (BiK) rates, reduced Vehicle Excise Duty liabilities, and other incentives depending on vehicle type and usage.

Electric car maintenance costs explained
When discussing electric car maintenance costs, it's important to understand how EVs differ from petrol and diesel vehicles.
Unlike traditional vehicles, electric cars do not require:
Oil changes.
Timing belt replacements.
Clutch repairs.
Exhaust system maintenance.
Spark plug replacements.
This often leads to lower servicing costs throughout the vehicle's lifetime.
What maintenance do electric cars need?
Although maintenance requirements are reduced, EVs still need regular servicing and inspections.
Common maintenance items include:
Tyre replacements.
Brake inspections.
Suspension checks.
Air conditioning servicing.
Cabin air filter replacement.
Battery health assessments.
Because EV batteries are heavy, tyre wear can sometimes be greater than on comparable petrol vehicles. However, the regenerative braking systems fitted to many EVs can reduce brake wear significantly.
Overall, electric car maintenance costs are generally lower than those associated with traditional vehicles.
The hidden costs of owning an electric car
While EVs can offer significant savings, there are some hidden costs of owning an electric car that prospective buyers should understand.
Home charger installation
Many EV owners choose to install a dedicated home charging point.
The upfront installation cost can vary depending on:
Property type.
Electrical system requirements.
Charger specification.
While this is typically a one-off expense, it should be factored into the overall ownership costs.
Public charging costs
Public charging can be more expensive than charging at home, particularly when using rapid and ultra-rapid chargers.
Drivers who regularly undertake long-distance journeys may therefore experience higher charging costs than those who primarily charge overnight at home.
Battery degradation
Although modern EV batteries are designed to last many years, all batteries naturally degrade over time.
Most manufacturers provide lengthy battery warranties, but battery performance may gradually reduce as the vehicle ages.
Insurance premiums
Some electric vehicles can be more expensive to insure due to higher repair costs and specialist parts.
However, insurance costs vary considerably between vehicle models and insurers.
Charging infrastructure planning
For businesses transitioning to electric fleets, charging infrastructure can represent a significant investment.
Our guide to Preparing for the EV Transition explores the practical considerations fleet operators should be aware of before making the switch.
EV running costs for business fleets
Businesses are increasingly adopting electric vehicles as part of their fleet strategy.
When managed effectively, EV running costs can help organisations reduce operating expenses while supporting sustainability goals.
Potential benefits include:
Lower fuel expenditure.
Reduced maintenance costs.
Simplified servicing schedules.
Lower emissions.
Potential tax efficiencies.
However, businesses should also consider:
Charging infrastructure requirements.
Driver charging reimbursement policies.
Route planning.
Vehicle suitability for specific operations.
Careful planning is essential to ensure the transition delivers the expected financial benefits.
How charging habits affect electric car running costs
The way an EV is charged can have a major impact on overall running costs.
Home charging
Home charging is often the most affordable option and can significantly reduce the cost to run an electric car.
Workplace charging
Businesses can support employees and fleet drivers by providing workplace charging facilities, helping to further reduce operational costs.
Public charging
Public charging networks offer convenience but may come at a higher cost than home charging.
Rapid charging
Rapid charging is ideal for longer journeys but is generally the most expensive charging option.
Businesses and drivers looking to maximise efficiency should also follow established EV charging best practices to help control costs and optimise battery performance.
Does vehicle weight affect EV running costs?
Vehicle weight can have a noticeable impact on efficiency.
Heavier electric vehicles typically require more energy to move, which can result in:
Reduced range.
Increased electricity consumption.
Higher charging costs.
Battery size, vehicle design, driving conditions, and load carried all contribute to overall efficiency.
For a deeper look at this topic, see our guide on electric car weight and how it affects performance and running costs.
Are electric cars worth it?
For many drivers and businesses, electric vehicles offer compelling long-term savings.
Although purchase prices may still be higher than some petrol or diesel alternatives, lower energy costs, reduced servicing requirements, and potential tax advantages can help offset the initial investment.
The key is understanding the full picture. While EV running costs are often lower, factors such as charging habits, infrastructure requirements, insurance, and battery performance should all be considered when calculating the true cost of ownership.
As charging infrastructure continues to improve and more businesses embrace electrification, electric vehicles are likely to become an increasingly attractive option for both private motorists and fleet operators.
FAQs around the cost of running an electric vehicle
How much does it cost to run an electric car?
