One of the advantages of electric cars is lower maintenance. But they still need servicing. Here's what you need to know.
EVs Need Less Servicing Than Petrol/Diesel
Why? Fewer moving parts:
| Component | Petrol/Diesel | EV |
|---|---|---|
| Engine oil | Yes — needs changing | No engine oil |
| Oil filter | Yes | None |
| Spark plugs | Yes (petrol) | None |
| Timing belt/chain | Yes | None |
| Clutch | Yes (manual) | None |
| Exhaust system | Yes | None |
| Fuel filter | Yes | None |
| Gearbox oil | Often | Single-speed, minimal |
Typical EV Service Intervals
Manufacturer Recommendations
| Manufacturer | Service Interval |
|---|---|
| Tesla | As needed / annual check |
| Hyundai/Kia | 12 months or 10,000 miles |
| VW Group | 12–24 months or 18,000 miles |
| BMW | Condition-based (car tells you) |
| Nissan | 12 months or 18,000 miles |
| Mercedes | 12–24 months |
| MG | 12 months or 10,000 miles |
General rule: Annual service or every 10,000–15,000 miles, whichever comes first.
What Gets Checked/Replaced
Every Service (Annual)
| Item | What Happens |
|---|---|
| Brake fluid | Check condition, replace if needed (every 2 years typical) |
| Cabin air filter | Replace (every 1–2 years) |
| Coolant | Check level and condition |
| Tyres | Check wear, pressure, alignment |
| Brakes | Inspect pads and discs |
| Suspension | Check condition |
| Lights | Test all lights |
| Wipers | Check condition, replace if worn |
| 12V battery | Test condition |
| Software | Update if available |
Periodic Items
| Item | Interval |
|---|---|
| Brake fluid replacement | Every 2 years |
| Coolant replacement | Every 4–8 years (varies) |
| Battery coolant | Every 4–8 years |
| Gearbox oil (if applicable) | 60,000–100,000 miles |
What's NOT Needed
| Item | Why Not |
|---|---|
| Oil changes | No engine oil |
| Oil filter | None exists |
| Spark plugs | No combustion engine |
| Fuel filter | No fuel system |
| Exhaust repairs | No exhaust |
| Emission tests | No emissions |
| Timing belt | No belt |
| Clutch replacement | No clutch |
Service Costs Comparison
Typical Annual Service Cost
| Vehicle Type | Typical Cost |
|---|---|
| Petrol car | £150–300 |
| Diesel car | £180–350 |
| Electric car | £80–150 |
Lifetime Maintenance Savings
Over 100,000 miles:
| Cost Type | Petrol | EV | EV Saving |
|---|---|---|---|
| Services | £1,500–2,500 | £600–1,200 | £900–1,300 |
| Brakes | £400–800 | £100–300 | £300–500 |
| Other repairs | £500–1,500 | £200–500 | £300–1,000 |
| Total | £2,400–4,800 | £900–2,000 | £1,500–2,800 |
Brakes Last Longer on EVs
Why?
Regenerative braking means:
What Still Needs Checking
Tip: Use friction brakes occasionally to keep them working properly.
Where to Service Your EV
Options
| Location | Pros | Cons |
|---|---|---|
| Main dealer | Manufacturer-trained, genuine parts | Most expensive |
| Independent EV specialist | Trained, often cheaper | May not have all diagnostic tools |
| General garage | Cheapest | May lack EV-specific knowledge |
What to Look For
Can Any Garage Service an EV?
Basic servicing: Yes — filters, brakes, tyres, fluids
EV-specific work: Needs trained technicians with HV certification
Battery/drivetrain: Usually dealer only
The 12V Battery
Often Overlooked
EVs have a small 12V battery (like any car) that:
Symptoms of failing 12V: Car won't start despite full traction battery, warning lights, electrical glitches.
Software Updates
Part of Modern EV Servicing
Many EVs receive over-the-air updates:
At service: Dealer may install updates not sent OTA.
Warranty Considerations

Summary
| Aspect | EV Advantage |
|---|---|
| Service frequency | Similar to petrol (annual) |
| Service cost | 40–60% cheaper |
| Major repairs | Far less common |
| Brake wear | Much slower |
| Complexity | Simpler overall |
The Bottom Line
EVs need less maintenance, and it costs less. Annual services are still recommended, but they're simpler and cheaper. The big-ticket items that plague older petrol/diesel cars (clutch, timing belt, exhaust, engine repairs) simply don't exist.
Budget around £100–150 per year for servicing, compared to £200–350 for an equivalent petrol car. Over the life of the car, you'll save £1,500–3,000 on maintenance alone.
