Introduction
Electric vehicles (EVs) promise cleaner air, lower running costs, and a glimpse into the future of driving.
But one of the most common claims is that they’re cheaper to maintain than traditional petrol or diesel cars.
Is it really true?
In this guide, we’ll break down exactly what EV maintenance involves, where you can save money, and where hidden costs might sneak in.
Why EVs Have Lower Maintenance Requirements
The key reason electric cars require less maintenance is simplicity.
Compared to internal combustion engine (ICE) vehicles, EVs have:
- No oil changes
- No spark plugs
- No timing belts
- No fuel systems
- No exhaust systems
Fewer moving parts mean fewer opportunities for things to wear out or break.
Typical drivetrain component count:
- EV: Around 20 moving parts
- Petrol/diesel car: Over 2,000 moving parts
This mechanical simplicity leads directly to lower servicing needs and fewer mechanical breakdowns.
Regular Maintenance Tasks for Electric Cars
While EVs need less servicing, they are not maintenance-free. Here’s what you’ll still need to care for:
- Tyre rotation and alignment: EVs are heavier, so tyre wear can be quicker.
- Brake system inspection: Thanks to regenerative braking, brakes last longer—but still need checking.
- Battery coolant system maintenance: Ensures optimal battery temperatures.
- Cabin air filter replacement: Usually once a year.
- Software updates: Often delivered remotely but sometimes require checks.
Tip: Follow your manufacturer’s service schedule to keep your EV running smoothly.
Comparing Maintenance Costs: EVs vs Petrol and Diesel Cars
Let’s look at some basics:
| Service Area | Petrol/Diesel Car | Electric Car |
|---|---|---|
| Oil changes | Every 10,000–15,000 km | Not needed |
| Brake pads | More frequent | Less frequent (regenerative braking) |
| Air filter replacement | Regular | Cabin filter only |
| Engine maintenance | Essential | None |
| Transmission repairs | Possible | Minimal (single-speed in most EVs) |
On average, EV owners spend about 30–50% less annually on servicing compared to ICE vehicle owners.
Common EV-Specific Repairs
Although EVs are simpler, they introduce some unique maintenance considerations:
- Battery cooling systems: These require occasional monitoring and maintenance.
- Charging port and cables: Need to be kept clean and inspected for wear.
- Software troubleshooting: Occasionally, updates or fixes might be needed, though these are often free.
Overall, such issues are rare and usually inexpensive compared to mechanical engine repairs.
Battery Health: Should You Be Concerned?
Batteries are the single most expensive component in an EV. Understandably, many buyers worry about lifespan and potential replacement costs.
Here’s what you need to know:
- Modern EV batteries are incredibly robust.
- Most lose only 1–2% capacity per year.
- Manufacturers often provide 8–10 year warranties on the battery.
After 8 years, many EVs still have 70–80% of their original capacity, more than enough for daily use.
Battery replacement is costly (£4,000–£8,000), but very few owners ever need one outside warranty.
Software Updates and Remote Diagnostics
Another hidden bonus:
Modern EVs can self-diagnose issues through software and receive updates over the air (OTA).
- Minor bugs or performance improvements can be fixed without visiting a garage.
- Some manufacturers (Tesla, Polestar, Ford) even unlock new features remotely after purchase.
Less time in the garage = lower maintenance costs and greater convenience.
When EV Maintenance Can Become Costly
There are a few situations where EVs can incur unexpected costs:
- Out-of-warranty battery replacement (though this is rare).
- Accident repairs: Bodywork for some EVs (especially Teslas) can be costly.
- High-voltage system repairs: If something does go wrong electrically, specialist repairs may be needed.
Still, for the average driver, these scenarios are rare during the first 8–10 years of ownership.
Real-World Cost Examples
Let’s compare typical servicing costs over 5 years:
| Vehicle | Estimated Maintenance Costs (5 years) |
|---|---|
| Nissan Leaf (EV) | ~£1,000–£1,500 |
| Ford Focus (Petrol) | ~£2,500–£3,500 |
Even without factoring in fuel savings, tax incentives, and reduced brake wear, EVs offer a clear maintenance advantage.
Final Thoughts
- Yes—EVs really are cheaper to maintain for most owners.
- They need fewer services, fewer replacement parts, and enjoy the benefits of software-based care.
- While battery concerns are valid, real-world data shows modern EVs are impressively durable.
Switching to an electric car not only saves on petrol—it reduces the time, hassle, and cost of traditional car ownership too.
Because when it comes to the future of driving, less maintenance truly means more freedom.
