Do Electric Cars Need Servicing? The Ultimate Guide for UK Drivers

Electric vehicles are becoming a familiar sight on UK roads now. With more public chargers, better range, and cheaper running costs, a lot of drivers are making the switch. But with that switch comes one question we hear at Advance Motors almost every week: Do electric cars need servicing?

It’s a fair question. People know EVs don’t have oil changes or spark plugs, so there’s a sense that the car looks after itself. But the truth is that electric cars still need attention, just in a different way than petrol and diesel models. They have fewer moving parts, yes, but they also rely heavily on electrical systems, cooling systems, and software that require proper checks.

If you’ve recently bought an EV or you’re thinking about one, this guide explains everything you need to know about servicing an electric car in the UK. No jargon, no over-complication, just practical information that helps you keep your EV in its best shape.

Do Electric Cars Need Servicing?

The straight answer is yes. All electric car needs servicing. The difference is in what gets checked and how often.

Electric cars have far fewer mechanical parts than traditional engines. There’s no oil, no exhaust, no clutch, no timing belt, no spark plugs, and no engine-filter replacements. But EVs still have brakes, tyres, suspension, cooling systems, and battery components that need professional inspection.

There are also software checks and battery-health diagnostics that simply didn’t exist with older cars. In our workshop at Advance Motors, we plug EVs into manufacturer systems to check their electronic modules, update the software, and run safety tests on the high-voltage components.

Skipping servicing can lead to bigger problems later, and in many cases, it invalidates the manufacturer's warranty. That’s why it’s not something to ignore.

Why Electric Cars Need Servicing Even With Fewer Moving Parts

Some drivers assume an EV should be maintenance-free. It feels logical at first because electric motors have so few wearable components. But here’s what most people don’t realise until they’ve owned an EV for a while.

1. The High-Voltage Battery Needs Professional Health Checks

The big battery pack is the heart of the car. It’s also the most expensive part to replace. EVs constantly monitor their own battery, but these systems still rely on proper servicing to catch early issues like:

• reduced state of health
• poor thermal performance
• charging irregularities
• cell imbalance
• cooling system faults

During servicing, technicians run battery health diagnostics and check how the car is managing heat. This helps you understand how the battery is ageing and whether anything needs attention now rather than later.

2. The Cooling System Protects the Battery

A lot of drivers don’t realise that EVs use coolant to keep the battery and electronics at the right temperature. If the coolant level drops or the system develops a leak, the car may limit power or refuse to fast charge.

Servicing includes checking the coolant condition and ensuring the thermal-management system is working correctly. This isn’t something you can identify visually at home.

3. The Brakes Still Wear (Just More Slowly)

Regenerative braking reduces wear, but it doesn’t eliminate it. Brake pads and discs can corrode faster on EVs because they aren’t used as heavily. When the brakes aren’t used regularly, moisture can build up and cause binding or uneven wear.

Brake fluid also still needs replacing every couple of years. Many UK drivers assume EVs don’t need brake work at all, but that’s not accurate.

4. Tyres Wear Out Faster Than Petrol Cars

EVs are heavier because of the battery weight. They also produce instant torque. This combination means tyres can wear quickly, especially on the driven wheels.

During EV servicing, we look for:

• uneven tyre wear
• cracking
• shoulder wear
• incorrect pressures
• damage from potholes

Tyre condition is a safety priority, and EV tyres follow UK legal tread laws just like any other car.

5. Software Updates Require Professional Tools

Modern EVs rely on software for:

• range accuracy
• battery conditioning
• driver-assistance features
• charging management
• safety systems

Some updates install automatically. Others require dealership tools. These updates often improve performance, fix bugs, and improve efficiency. Servicing ensures the car is fully up to date.

6. Suspension wear is common on heavier EVs

Because electric cars are heavier, components like bushings, track rods, drop links and dampers experience more strain than on some smaller petrol cars. Regular servicing helps catch issues before they turn into knocks, loose handling or uneven tyre wear.

What’s Included in an Electric Car Service?

This is another question we hear often. The simplest way to understand it is that EV servicing focuses on electrical health, software, cooling, and general vehicle checks rather than engine work.

A typical EV service includes:

Battery Health Inspection

• state of health
• battery conditioning systems
• temperature regulation checks

Brake System Inspection

• brake pads and discs
• hydraulic system
• fluid condition

Tyre and Wheel Checks

• tread depth, pressure and wear patterns
• rotation if needed
• alignment if pulling or uneven wear is found

Cooling System Inspection

• coolant level
• cooling lines
• heat-pump system (on some EVs)

Steering and Suspension

• joints
• bushes
• mounts

Cabin Filter Replacement

EVs rely heavily on their HVAC systems because they don’t have a traditional heater. Clean filters are important.

Software and Diagnostic Scan

We check for:

• error codes
• software updates
• calibration issues
• service alerts

It’s much more diagnostic-driven compared to petrol servicing.

How Often Do Electric Cars Need Servicing in the UK?

It varies by manufacturer, but most EVs follow: once a year or every 10,000 to 20,000 miles. Whichever comes first.

Some brands stretch the interval longer, but from our experience at Advance Motors, annual inspections are smart, especially with UK weather and road conditions.

Short journeys, potholed roads and winter temperatures all affect EV components differently, so a yearly check keeps things running smoothly.

Is EV Servicing Cheaper Than Petrol or Diesel?

In most cases, yes. EV servicing tends to be cheaper than petrol version for one simple reason: there are fewer mechanical parts to maintain.

What EV owners save money on:

• engine oil
• spark plugs
• clutch
• timing belts
• exhaust repairs
• fuel filters
• engine diagnostics

Costs that still apply:

• brake fluid
• coolant
• tyres
• suspension work
• cabin filter
• >MOT (though EVs skip emissions tests)
• battery health checks (varies by dealership)

Long-term, EV maintenance costs are lower. But regular servicing still matters to keep the car safe and to protect the battery.

Common Myths About Electric Car Servicing

Let’s clear up a few misconceptions we hear often from customers.

Myth 1: EVs never need servicing

Not true. They require less, not none.

Myth 2: Regenerative braking means brakes last forever

Brakes last longer, but they still corrode and need fluid changes.

Myth 3: The battery lasts the lifetime of the car

Modern EV batteries are durable, but degradation still happens. How much it depends on driving habits and charging routines.

Myth 4: Software updates happen automatically

Some do. Some require workshop tools.

Myth 5: EV servicing is expensive

Usually, the opposite. EVs tend to be cheaper to maintain annually.

Do Electric Cars Still Need an MOT in the UK?

Yes, but the test is slightly different. EVs have no emissions test, so that part of the MOT is skipped. But MOT testers still check: lights, tyres, suspension, brakes, steering, structural integrity, seatbelts, and high-voltage system safety markers.

EVs need their first MOT after 3 years, just like any other vehicle.

How Battery Health Affects Servicing Needs

Battery health is something that doesn’t exist in petrol cars, but it’s one of the most important aspects of EV ownership. Factors that impact battery health:

• frequent rapid charging
• extreme cold or heat
• long periods at high charge (near 100 percent)
• constantly running low
• cabin filter
• short repeated trips

A battery with poor thermal management or repeated deep discharges may show reduced range. This is why regular servicing and battery checks help catch early signs of decline.

Most EVs lose between 1 and 3 percent battery health per year. Well-maintained ones lose even less.

Unexpected EV Issues That Can Show Up Between Services

Even with fewer parts, EVs are not immune to the occasional hitch. Some of the issues we’ve seen in our workshop include:

• faulty charge ports
• damaged charging cables
• corroded connectors
• software glitches
• damaged HV wiring from debris
• 12V auxiliary battery failure
• coolant leaks
• worn suspension bushings

The small 12V battery is a big one. Many drivers assume only the main high-voltage battery matters, but the 12V battery starts the systems that allow the main battery to activate. If the 12V battery fails, the car won’t start even if the main battery is full.
