As more UK drivers consider making the switch to electric vehicles (EVs), cost is a key factor in the decision-making process. While purchase prices can be higher for EVs, many people are attracted by the promise of lower running costs – particularly when it comes to servicing. But are electric cars cheaper to maintain than their petrol or diesel counterparts?
The answer lies in the differences in design, components, and servicing needs. Understanding these differences can help you decide if an EV is the right choice for your budget and driving habits.
Fewer Moving Parts Mean Less Maintenance
One of the biggest advantages of electric cars is their simpler mechanical design compared to petrol or diesel vehicles.
- No Oil Changes – EVs don’t have an engine that requires regular oil and filter changes.
Fewer Wear-Prone Components – There’s no exhaust system, fuel injectors, or clutch to maintain. - Simpler Transmission – Most EVs have a single-speed gearbox, which is less complex and less prone to failure.
- No Timing Belt Replacements – A common and costly job in petrol/diesel cars is unnecessary in EVs.
This reduction in moving parts means there’s less to go wrong, often resulting in fewer workshop visits and lower labour costs.
Areas Where EVs Still Need Regular Attention
While EVs generally need less servicing, they are not maintenance-free. Certain components still require regular checks and replacements.
- Tyres – EVs can be heavier than petrol/diesel cars, leading to faster tyre wear.
- Brakes – Regenerative braking reduces wear, but pads and discs still need periodic replacement.
- Suspension – The extra weight of the battery pack can put more strain on suspension components.
- Cabin Filters and Fluids – Air conditioning filters, coolant for battery systems, and brake fluid still need scheduled servicing.
It’s essential to note that, although overall costs may be lower, some replacement parts for EVs can be more expensive due to limited availability.
Comparing Average Servicing Costs in the UK
When looking at typical UK servicing costs, EVs generally come out ahead – but with some caveats.
- Annual Service Costs – Many EV services cost around £100–£200, compared to £200–£400 for petrol/diesel models.
- Brake Maintenance – Thanks to regenerative braking, EV brake components can last significantly longer, reducing replacement costs.
- MOT Costs – MOT prices are the same for all cars, but EVs are less likely to fail on emissions-related issues.
- Battery Health Checks – Some EV services include a battery inspection, which can add cost but is vital for long-term performance.
While servicing is generally cheaper, EV repairs after accidents or battery-related issues can be costly, so comprehensive insurance is important.
Tips to Keep Your EV Servicing Costs Low
Even with lower maintenance demands, you can take steps to further reduce your EV running costs.
- Choose an Independent EV Specialist – They often charge less than main dealers while still having the right training and tools.
- Follow the Manufacturer’s Schedule – This keeps your warranty valid and prevents small issues from becoming expensive problems.
- Drive Smoothly – Avoiding aggressive acceleration can reduce tyre and suspension wear.
- Keep Software Updated – Updates can improve efficiency and prevent issues without a garage visit.
- Check Tyres and Fluids at Home – A quick weekly inspection can prevent unexpected trips to the garage.
With these habits, you can maximise the cost-saving potential of EV ownership.
Electric cars are generally cheaper to service than petrol or diesel vehicles in the UK, thanks to their simpler design and fewer wear-prone parts. While they still require attention to tyres, brakes, and suspension, the overall annual servicing bill is usually lower.
However, potential high repair costs for battery or specialist components mean that good maintenance and comprehensive insurance are still essential. For most drivers, the reduced servicing costs are another compelling reason to consider making the switch to electric.
