Do Electric Cars Need Servicing? EV Maintenance Costs Explained

Summary

• Less maintenance needed: EVs have fewer moving parts. No oil changes, no spark plugs, no exhaust system to worry about.
• Still requires servicing: Brakes, tyres, suspension, coolant, and cabin filters still need attention. Most manufacturers recommend annual services.
• Lower costs: EV servicing typically costs 30-50% less than equivalent petrol/diesel cars. Check your MOT history to stay on top of issues.

One of the biggest benefits of electric cars is lower maintenance costs. Fewer moving parts means fewer things to go wrong.

But that doesn't mean EVs are maintenance-free. This guide explains exactly what servicing an electric car involves and what you can expect to pay.

What Electric Cars DON'T Need

Compared to petrol and diesel cars, EVs skip many traditional maintenance items:

Component	Petrol/Diesel	Electric
Engine oil	Change every 10,000-15,000 miles	Not needed
Oil filter	Replace with oil change	Not needed
Spark plugs	Replace every 30,000-60,000 miles	Not needed
Timing belt/chain	Replace every 60,000-100,000 miles	Not needed
Exhaust system	Can corrode, needs inspection	Not needed
Clutch	Wears over time	Not needed (single-speed)
Fuel filter	Replace periodically	Not needed

This is why EVs have lower running costs. You simply don't need many of the expensive maintenance items that combustion cars require.

What Electric Cars DO Need

EVs still have components that wear out or need regular attention:

Tyres

EVs are heavy (those batteries weigh a lot) and have instant torque. This combination means tyres can wear faster than on equivalent petrol cars.

• Check tread depth and pressure regularly
• Rotate tyres according to manufacturer schedule
• Consider EV-specific tyres designed for the extra weight

See our tyre tread guide for more details.

Brakes

Good news: EV brakes last longer thanks to regenerative braking. The motor slows the car and recovers energy, reducing wear on brake pads.

However, brakes still need inspection. Less use can mean corrosion if brake discs aren't used enough to stay clean.

Suspension and Steering

These components work the same as in any car. Bushings, ball joints, and dampers all wear over time and need inspection.

Cabin Air Filter

EVs still have cabin air filters that need replacing. Some have HEPA filters that are more expensive but last longer.

Battery Coolant

Most EVs have a thermal management system to keep the battery at optimal temperature. The coolant in this system needs checking and occasional replacement.

This is different from engine coolant in petrol cars, but serves a similar purpose.

Windscreen Wipers and Washers

These wear out just like any car. Replace wipers when they streak. See our wiper blade guide.

12V Battery

Yes, EVs still have a 12V battery! It powers the lights, computers, and accessories when the main battery is off. It typically lasts 4-6 years.

Typical EV Service Schedule

Most manufacturers recommend annual services or every 10,000-15,000 miles. Here's what a typical schedule looks like:

Interval	What's Checked/Replaced
Annual / 10,000 miles	Brake inspection, tyre check, fluid levels, cabin filter, software updates
Every 2 years	Brake fluid test/replacement, battery coolant check
Every 4-5 years	Battery coolant replacement, 12V battery replacement
As needed	Tyres, wiper blades, brake pads/discs

Always check your owner's manual for manufacturer-specific recommendations.

How Much Does EV Servicing Cost?

EV servicing is generally cheaper than petrol or diesel vehicles:

Car Type	Typical Annual Service Cost
Small petrol hatchback	£150-250
Medium diesel car	£200-350
Electric hatchback	£100-200
Tesla (using Tesla service)	£150-300
Premium EV (Porsche, Audi)	£200-400

Over a typical ownership period, EV owners save hundreds of pounds on maintenance compared to equivalent combustion cars.

Battery Health and Longevity

The biggest concern for many EV owners is battery degradation. Here's what you need to know:

How Long Do EV Batteries Last?

Modern EV batteries are designed to last the lifetime of the vehicle. Most manufacturers warranty batteries for 8 years or 100,000 miles.

Degradation does occur, but it's typically slow. Expect around 2-3% capacity loss per year under normal use.

What Affects Battery Life?

• Fast charging: Frequent DC rapid charging generates heat. Occasional use is fine, but relying on it exclusively can accelerate wear.
• Temperature extremes: Very hot or cold conditions stress the battery. Most EVs have thermal management to mitigate this.
• State of charge: Keeping the battery between 20-80% most of the time is ideal. Regularly charging to 100% or draining to near-empty isn't optimal.
• Age: Batteries degrade over time even without use, though slowly.

Battery Replacement Cost

If a battery does need replacing outside warranty, costs vary widely:

• Small EV: £5,000-10,000
• Mid-size EV: £10,000-15,000
• Large/premium EV: £15,000-25,000+

MOT Requirements for Electric Cars

EVs still need an annual MOT once they're 3 years old. The test is simpler because there's:

• No emissions test
• No exhaust to check
• No fuel system inspection

However, the test still covers:

• Brakes
• Tyres
• Lights
• Steering and suspension
• Seatbelts
• Windscreen and wipers
• High-voltage safety (visible cable condition, warning lights)

EVs have a high MOT pass rate because they have fewer components to fail.

Where to Get Your EV Serviced

Manufacturer Dealerships

The safest option. They have trained technicians and access to software updates. Often required to maintain warranty.

Independent EV Specialists

Growing in number. Can be cheaper than dealers while still having EV-specific expertise. Check reviews carefully.

General Garages

Many tasks (tyres, brakes, suspension) don't require EV-specific training. But avoid garages unfamiliar with high-voltage systems for anything electrical.

Safety note: High-voltage components in EVs are dangerous. Only qualified technicians should work on the electrical system.

---

Software Updates

EVs are essentially computers on wheels. Software updates can:

• Improve range and efficiency
• Add new features
• Fix bugs and improve reliability
• Update charging compatibility

Tesla updates over-the-air automatically. Other manufacturers may require a dealer visit for some updates.

Keep your car's software current for the best performance and security.

Common Questions

• Can any garage service an electric car?
  For basic items like tyres and brakes, yes. For anything electrical or battery-related, use a qualified EV technician.
• Do EVs need oil changes?
  No. Electric motors don't use oil. Some EVs have gearbox fluid that may need changing, but it's infrequent.
• How often should I service my electric car?
  Most manufacturers recommend annually or every 10,000-15,000 miles. Check your owner's manual.
• Are EV brake pads cheaper to replace?
  No, the parts cost is similar. But they last much longer thanks to regenerative braking, so you replace them less often.
• Does skipping servicing void my warranty?
  It can. Most warranties require following the manufacturer's service schedule. Keep records of all servicing.

Final Thoughts

Electric cars do need servicing, but it's simpler and cheaper than petrol or diesel vehicles. With no oil changes, no spark plugs, and regenerative braking extending brake life, your maintenance bills will be lower.

The key is finding a technician qualified to work on EVs, keeping up with the manufacturer's service schedule, and looking after your battery with good charging habits.

Do that, and your EV should provide years of reliable, low-cost motoring.
