Do Electric Cars Need Servicing

Electric cars are now a familiar sight on UK roads, and with their rise in popularity comes a common question from drivers and homeowners alike. If electric vehicles are so different from petrol and diesel models, do they still need servicing? Many people assume that because electric cars have fewer moving parts, they require little or no maintenance at all. While it is true that servicing demands are reduced compared to traditional vehicles, regular checks and upkeep are still important for safety, performance, and long-term reliability.

Why Servicing Matters for Electric Cars

All vehicles, whether powered by fuel or electricity, are subject to wear and tear over time. Tyres, brakes, suspension, and steering components all need attention regardless of what is under the bonnet. With electric cars, the absence of an internal combustion engine does reduce the number of parts that require maintenance, but servicing remains essential to keep the car safe and roadworthy. In the UK, MOT requirements still apply to electric vehicles, meaning safety-critical systems must be regularly inspected.

Servicing is also important because electric vehicles rely heavily on advanced technology. Battery management systems, high-voltage components, and cooling systems all require careful inspection by trained technicians who understand the unique design of electric drivetrains. A lack of servicing could lead to reduced performance or even safety risks if potential problems go unnoticed.

The Differences Between Servicing Electric and Petrol Cars

Traditional cars rely on engines that burn fuel, which requires regular oil changes, spark plug replacements, exhaust maintenance, and timing belt inspections. Electric cars remove all of these needs. There is no oil to change, no gearbox filled with multiple gears to maintain, and no exhaust system to replace. Instead, the electric motor is a sealed unit with far fewer serviceable parts.

However, electric cars still require regular servicing of key areas. Brake fluid needs to be checked, as hydraulic systems are still used alongside regenerative braking. Coolant systems for the battery and motor must also be inspected, as overheating could reduce efficiency or damage components. Software updates are another unique aspect of electric vehicle servicing, as many manufacturers improve vehicle performance and safety through digital updates.

The Role of the Battery in Servicing

The battery is the most important and expensive component in an electric car. While modern lithium-ion batteries are designed to last for many years, their performance can decline over time if not properly maintained. Servicing helps monitor battery health, ensuring it charges and discharges efficiently. Thermal management is key, as batteries that are not kept within the correct operating temperature can lose range or in severe cases develop faults.

Technicians carry out diagnostic checks to measure battery performance, capacity, and charging efficiency. This data helps identify potential issues early, preventing costly repairs later. For UK drivers who rely on their electric cars daily, these checks are essential to guarantee long-term reliability.

Common Areas Checked During Servicing

Although electric vehicles have fewer service needs, there are still several areas that require routine attention. Tyres must be inspected for tread depth and wear, as electric cars are often heavier than petrol cars due to the battery, which can place extra strain on tyres. Brake systems are checked for both mechanical wear and fluid levels. Suspension and steering are also inspected to ensure the car remains safe and comfortable to drive.

Electrical systems, including the high-voltage cables, are checked for damage or wear. Heating and air conditioning systems, which often rely on electric compressors, must also be maintained. In addition, safety features such as lights, windscreen wipers, and driver-assist technology are all inspected during servicing.

How Often Do Electric Cars Need Servicing?

The frequency of servicing depends on the manufacturer, but most recommend a service every 12 months or a set number of miles, whichever comes first. Some electric cars may require less frequent servicing due to their simpler design, but drivers should not assume this means they can ignore maintenance altogether. Following the manufacturer’s guidance is important not only for safety but also for preserving warranties.

In the UK, electric cars must also undergo an MOT after three years, just like petrol and diesel cars. The MOT covers areas such as brakes, tyres, lights, and suspension, ensuring the vehicle remains safe for use on the road. The test does not include emissions checks, as electric cars produce no exhaust gases, but all other safety standards still apply.

Cost of Servicing Electric Cars

One of the advantages of owning an electric vehicle is that servicing is often cheaper than with traditional cars. Fewer parts need replacing, and the electric motor requires little maintenance. However, specialist knowledge is needed to work safely with high-voltage systems, which means servicing should only be carried out by trained technicians. In the UK, many garages are now investing in training and equipment to support electric vehicles, giving drivers more choice when it comes to servicing.

Costs will vary depending on the make and model, but in general, electric car servicing tends to be more affordable in the long run. Reduced wear on brakes due to regenerative systems and fewer engine-related repairs mean owners can save money over the lifetime of the vehicle.

Why Servicing Should Not Be Ignored

Some drivers may be tempted to put off servicing because electric cars seem more reliable. While it is true they often experience fewer breakdowns, ignoring servicing can lead to problems that reduce performance and increase costs later. For example, worn tyres can affect efficiency and safety, and neglected brake systems can lead to dangerous failures. Battery faults that go unchecked can also become expensive to repair.

Regular servicing also helps maintain the value of the car. A full service history reassures future buyers that the vehicle has been well cared for, which can make a big difference when selling or trading in.

Conclusion

Electric cars do need servicing, although the type and frequency of maintenance differ from petrol and diesel models. They benefit from fewer moving parts and reduced wear, which lowers costs and simplifies upkeep. However, the battery, motor, and high-voltage systems still require professional inspection, and routine checks of tyres, brakes, and suspension remain essential. For UK drivers, following manufacturer servicing schedules and keeping up with MOT requirements is the best way to ensure an electric vehicle remains safe, reliable, and cost-effective for years to come.
