EV vs Petrol and Diesel: What Servicing Really Costs UK Drivers

If you are weighing up an electric car against a petrol or diesel model, running costs matter just as much as the price on the windscreen. Fuel and tax get most of the attention, but vehicle servicing is where the real day-to-day difference shows up. Here is why: an EV and a petrol car are built differently under the skin, and that changes what a mechanic actually does when your car goes in for a check-up.

This guide breaks down what UK drivers can expect to pay for routine car maintenance on each type of vehicle, what gets checked, and where the hidden costs sit. Let's break it down properly, using figures from UK-based sources rather than guesswork.

Why Servicing Costs Differ Between EVs and Petrol Cars

A petrol or diesel engine has hundreds of moving car parts. Pistons, valves, a timing belt or chain, a fuel injection system, an exhaust with a catalytic converter, and a gearbox all wear down over time and need regular attention. Every one of these components adds a line item to your bill.

An electric motor has a fraction of the moving parts. There is no oil to change, no spark plugs, no exhaust system, and no clutch on most models. That simplicity is the main reason electric vehicle maintenance tends to cost less over the life of the car, according to guidance from Dick Lovett, a UK main dealer group.

That does not mean an EV needs no attention at all. Garages still check the battery, high-voltage cabling, cooling systems, brakes, tyres, and software. It just means fewer of those checks involve replacing worn mechanical parts.

Average Vehicle Servicing Costs Compared

Prices vary by make, model, and garage, but the pattern across independent UK sources is consistent. Here is a rough picture for a typical family car, based on data from Car Friend and Dick Lovett:

• Petrol or diesel full service: roughly £220 to £350, sometimes more once parts like timing belts or clutches need replacing.

• Electric car full service: roughly £160 to £240, depending on vehicle size and whether you use a dealer or an independent specialist.

• Annual servicing average: EV owners often report figures nearer £150 to £250 a year, against £300 to £500 for petrol cars once age-related repairs are factored in.

Put simply, most drivers can expect to save something in the region of 20 to 40 per cent on servicing by going electric, though this narrows if you need specialist battery or high-voltage work done at a dealership rather than a trained independent garage.

What Routine Car Maintenance Looks Like for Each

The best way to understand the cost gap is to look at what actually happens during a service.

Petrol and Diesel Servicing Checklist

A typical interim or full service on a petrol or diesel car usually covers:

1. Engine oil and filter change

2. Air filter and fuel filter checks or replacement

3. Spark plug inspection (petrol) or glow plug checks (diesel)

4. Timing belt or chain inspection, with replacement at set mileage intervals

5. Exhaust and emissions system checks

6. Clutch and gearbox fluid checks

7. Brake, tyre, and suspension inspection

Several of these, especially the timing belt and clutch, are expensive once they need replacing rather than just checking. This is where preventive car maintenance pays off. Catching a worn belt early is far cheaper than dealing with the engine damage it causes if it snaps.

EV Servicing Checklist

An electric car service focuses on different areas:

1. Battery health and cell diagnostics

2. High-voltage cable and connector inspection

3. Cooling system checks for the battery and motor

4. Brake fluid and brake component checks

5. Tyre condition, tread depth, and wear pattern

6. Software updates and fault-code scans

7. Suspension and steering checks

Notice what is missing. No oil change, no spark plugs, no exhaust, no clutch. That is roughly half the usual checklist gone, which is the main reason auto maintenance services for EVs cost less on paper.

Hidden Costs to Watch: Tyres and Brakes

EVs are not maintenance-free, and two areas can catch new owners out.

Tyres wear faster. Electric cars are heavier than their petrol equivalents because of the battery pack, and they deliver instant torque from a standstill. Both factors increase tyre wear, so budget for replacing tyres somewhat more often than you would on a petrol car of the same size.

Brakes often last longer, not shorter. Most EVs use regenerative braking, which slows the car by feeding energy back into the battery rather than relying purely on the brake pads. This means brake pads and discs typically last longer on an EV than on a comparable petrol car, according to Dick Lovett's maintenance guidance.

Battery replacement is the wildcard. A full battery replacement is expensive if it ever happens outside warranty, though most manufacturers now offer battery warranties of around eight years. For the vast majority of owners, this cost never materialises within a normal ownership period.

MOT Rules for EVs vs Petrol Cars

One area where the two are almost identical is the MOT. Electric cars still need an annual MOT test from three years old, exactly like petrol and diesel cars. The only real difference is that there is no tailpipe emissions test for an EV, since there is no tailpipe to test. Everything else, including tyres, brakes, lights, suspension, steering, seatbelts, and visibility, gets checked the same way it would on any other car.

How to Keep Servicing Costs Down, Whatever You Drive

Whether you run an EV, a petrol car, or a diesel, a few habits keep your bills lower over time:

• Stick to the service schedule. Skipping a service to save money now often costs more later, since small issues turn into bigger repairs.

• Use a garage that knows your vehicle type. EVs need technicians trained to work safely with high-voltage systems. Petrol and diesel cars need mechanics who know the engine and gearbox well.

• Check tyre pressure and tread regularly. This is one of the simplest forms of preventive car maintenance, and it matters even more on a heavier EV.

• Compare quotes before booking. Prices for the same job can vary a fair amount between garages in the same area, so it is worth checking before you commit.

• Keep records. A full service history protects your car's resale value, whether it runs on petrol, diesel, or electricity.

If you are searching for car maintenance near me and want to compare options without ringing round several garages, Drivlu lets you book vehicle servicing online and see upfront pricing before you commit. The platform connects drivers across the UK with local, vetted garages for everything from routine maintenance to MOTs, so you are not stuck guessing what a job should cost.

Which Is Actually Cheaper to Service?

On the numbers alone, electric cars come out ahead for routine servicing. Fewer parts, simpler systems, and longer-lasting brakes all point the same way. Petrol and diesel cars are not necessarily bad value, though, especially if you keep up with maintenance and avoid the big repair bills that come from ignoring early warning signs.

The honest answer is that both types of car reward good habits. Regular checks, a trusted garage, and catching small problems early will keep your costs down no matter what is under the bonnet. If you want affordable car repair and servicing without the guesswork, comparing your options through a service like Drivlu is a straightforward way to see real prices before you book.

FAQs

Is it cheaper to service an electric car than a petrol car in the UK? 

Yes, in most cases. EVs typically cost 20 to 40 per cent less to service because they skip oil changes, spark plugs, and exhaust work. Petrol and diesel cars need more mechanical upkeep as they age, which adds to the total bill over time.

Do electric cars need an MOT? 

Yes. Electric cars need an MOT from three years old, the same as petrol and diesel cars. The only difference is there is no emissions test, since EVs have no tailpipe.

Why do EV tyres wear out faster? 

EVs are heavier due to the battery pack and produce instant torque, which puts more strain on tyres. Regular pressure checks and careful driving can help slow this down.

Do EV brakes last longer than petrol car brakes? 

Usually, yes. Regenerative braking means the electric motor handles much of the slowing down, so brake pads and discs see less wear and often last longer between replacements.

How often should I service my car for preventive maintenance? 

Most manufacturers recommend a service every 12 months or 10,000 to 12,000 miles, whichever comes first. Sticking to this schedule, whether for an EV or a petrol car, helps catch small issues before they become costly repairs.
