How Often Should You Service an Electric Car?

Electric cars need servicing less frequently than petrol or diesel vehicles, but they are not maintenance-free. Because there is no engine oil to change, no timing belt to replace, and no spark plugs to wear out, the service checklist is shorter and the intervals between visits can be longer. That said, tyres, brakes, cabin filters, coolant, and brake fluid all still require attention, and your manufacturer's schedule remains the authoritative guide for your specific model. You can find the right charging cable for your EV and other ownership guides in our resource section.

Why do electric cars need less servicing than petrol cars?

A petrol or diesel engine has hundreds of moving parts that wear, require lubrication, and eventually need replacing. An electric motor has far fewer moving parts and no combustion to manage, so many of the most time-consuming and expensive service items simply do not exist. There is no engine oil, no oil filter, no air intake filter, no spark plugs, no timing belt, no exhaust system, and no clutch in most cases. The result is a significantly shorter service checklist and, for many drivers, lower average maintenance costs over the life of the vehicle, particularly during the middle years of ownership once the initial warranty period has passed.

What is actually checked during an EV service?

While the list is shorter, an EV service is not trivial. A trained technician will typically inspect or carry out the following:

• Tyres: tread depth, pressure, condition, and signs of uneven wear. EVs are heavier than equivalent ICE cars and deliver torque instantly, which can accelerate tyre wear, so this check matters.
• Brakes: pad thickness and disc condition. Because regenerative braking handles much of the deceleration, pads and discs last considerably longer, but they are still inspected for corrosion and function.
• Cabin air filter: replaced if dirty or past its service life, typically every one to two years.
• Coolant levels and condition: EVs use coolant to manage the temperature of the battery pack and motor, rather than an engine. The coolant still degrades over time and requires periodic replacement.
• Battery health check: a diagnostic report on the battery's state of health, capacity retention, and charging behaviour.
• Software updates: over-the-air updates handle many changes automatically, but some updates require the vehicle to be connected to workshop equipment.
• Suspension, steering, and lights: checked in the same way as any other vehicle.
• Windscreen wipers and washer fluid: simple but still part of a complete check.

How often should you service an electric car?

Follow your manufacturer's recommended schedule without exception. Most manufacturers suggest an annual service or a mileage-based interval, whichever comes first, though some higher-mileage drivers on longer intervals will find mileage triggers the visit rather than the calendar. The service interval for an EV is often longer than for a petrol equivalent, which is one of the practical ownership advantages. Do not be tempted to skip or delay services because the car feels fine: battery health checks and software updates need a workshop visit that cannot be self-assessed, and some items like brake fluid degrade on a time basis regardless of mileage.

Do electric cars still need an MOT?

Yes. An electric car requires an MOT from three years old, exactly the same as any other passenger car registered in the UK. The MOT checks cover brakes, tyres, lights, steering, suspension, body condition, and emissions (EVs produce zero tailpipe emissions, which they pass by definition). The battery is not directly part of the MOT test, but the vehicle's electrical safety systems and high-voltage warning labels are checked. Some older or specialist MOT stations may not have the specific connectors or diagnostic equipment for certain EV models, so it is worth choosing a centre familiar with electric vehicles.

Why does brake fluid still need replacing in an EV?

Brake fluid is hygroscopic, meaning it absorbs moisture from the atmosphere over time. As moisture content rises, the fluid's boiling point drops, which can lead to reduced braking performance under heavy or sustained use. This process happens regardless of how often the brakes are physically applied, which means it is time-based rather than mileage-based. Even if regenerative braking means your brake pedal is rarely depressed firmly, the fluid in the system still ages and still needs changing on schedule. Most manufacturers recommend a replacement interval of around two years, but check your vehicle's handbook for the specific requirement.

What does a battery health check actually cover?

A battery health check uses manufacturer-specific diagnostic software to measure the current state of health of the traction battery. It typically reports on the remaining usable capacity compared with the battery's original specification, the balance between individual cell groups, charging behaviour, and any fault codes stored in the battery management system. A healthy battery will retain the great majority of its original capacity for many years under normal use, but the check gives you a documented record and can identify any cells or modules that are beginning to underperform. Some manufacturers offer warranty protection on battery capacity below a defined threshold for a set number of years or kilometres: keeping service records showing regular health checks supports any future warranty claim.

Frequently asked questions

Is servicing an electric car cheaper than a petrol car?

Generally yes, over the long term, because there are fewer consumable parts and fewer labour-intensive service items. You will not pay for oil changes, timing belt replacements, or spark plugs. However, some EV-specific items, such as tyre replacement on heavier models, can cost more than the equivalent on a lighter petrol car. The overall saving varies by model, mileage, and how long you keep the vehicle.

Can any garage service an electric car?

Basic checks on tyres, wipers, lights, and visual inspections can be carried out by most garages. However, high-voltage system work, battery diagnostics, and software updates require trained EV technicians and specific equipment. For a thorough service that covers all manufacturer-specified items, use an authorised dealer or an independent garage with recognised EV qualifications.

Does regenerative braking mean brake pads never need replacing?

They last considerably longer in most EVs because regenerative braking handles a large proportion of normal deceleration without touching the friction brakes at all. However, brake pads and discs still wear eventually, and discs can also corrode if the friction brakes are rarely used. Technicians check both at each service. Replacement intervals vary widely by model and driving style, but most EV owners find they go much further between brake jobs than in a petrol car.

What happens if I miss a service on my EV?

Missing a service can affect your manufacturer warranty, particularly for battery coverage, as many warranties require evidence of adherence to the service schedule. You also risk missing brake fluid degradation, tyre issues, or software updates that could affect safety or efficiency. Book in promptly if you have fallen behind, and keep all records carefully.

Do EV tyres wear out faster than on a petrol car?

They can, for two reasons: EVs are typically heavier due to the battery pack, putting more load on each tyre; and the instant torque delivery of an electric motor can cause more tyre stress during acceleration. Some EV-specific tyre designs are optimised for lower rolling resistance and higher load ratings. Checking and rotating tyres regularly helps extend their life and keeps the wear even across all four wheels.

Are software updates part of the service or separate?

Many manufacturers push software updates over-the-air, meaning the car downloads and installs them without a visit to the garage. However, some updates, particularly those affecting critical vehicle systems, require connection to workshop diagnostic equipment and are applied during a scheduled service. Check your manufacturer's app or owner portal to see which updates have been applied and whether any require a visit.

Servicing an electric car is simpler than maintaining a petrol vehicle, but staying on top of the manufacturer's schedule protects your battery warranty and keeps everything working as it should.
