Combustion Engine and EV Servicing

Are you thinking about purchasing a new car but unsure about whether to opt for a combustion engine or an electric one? Traditional cars, also referred to as ICE vehicles, have been in existence for more than a century and are extensively used across the globe. They rely on internal combustion engines that transform the energy from burning fuel into mechanical energy to propel the car forward. However, toxic emissions from tailpipes of diesel and petrol cars have caused air pollution problems that is having a negative effect on the world as we know it – whereas electric vehicles are known to be better for the environment, and the purse-strings in regards to the maintenance of the car.

The United Kingdom is experiencing a surge in demand for electric vehicles and by 2028, unit sales of Electric Vehicles market in the United Kingdom are expected to reach 573.10k vehicles.

While electric vehicles, or EVs, are increasing in popularity over the years many people still like (or love) driving a petrol/diesel car – whatever your preference you should ensure that they are maintained well to ensure optimal performance and longevity.

It is important to note that a car service should not be confused with an MOT, which is a legal requirement for cars over three years old.

Combustion Engine Servicing

Car services are designed to keep your vehicle in optimal condition, ensuring both safety and ideal performance.

The extent of the service depends on the type you choose, as it will determine what is included. Opting for a full service means you can expect an engine oil and filter change, a thorough inspection of all fluids, a comprehensive brake check, and evaluations of over 50 other crucial components, including safety-related features.

Car services can also include minor repairs like belt tightening and timing adjustments, as well as more extensive repairs if required.

What Service Should I Choose and When?

Service Type


Regular Maintenance

When oil and filter need replacement

Interim Service

Every 6 months or 6,000 miles (whichever comes first)

Full Service

Every 12 months or 12,000 miles (whichever comes first)

Manufacturer Service

As per manufacturer service schedule, check your car manual for information

Regular maintenance is key to extending the lifespan of your car. By ensuring that all essential components are in optimal condition, your vehicle will remain roadworthy even after the warranty period expires. While servicing your car isn’t a legal requirement, it is integral to the car’s and therefore your own, safety. It gives your chosen mechanic the opportunity to spot anything wrong with the vehicle before it becomes a more serious problem.

Electric Vehicle Servicing

What’s potentially surprising is that electric motors are fairly simple, with most units made up of no more than 20 components; unlike their ICE counterparts that have thousands of moving parts. This means the motors are less likely to receive that much attention in a service which is one of the key differences in EV maintenance.

There’s no need to worry about changing oil or renewing filters, or even replacing the cambelt and water pump. However, a quick diagnostic check is still necessary to catch any potential fault codes that may require attention. The battery, on the other hand, is even easier to maintain as it has no moving parts whatsoever. Each individual cell will be thoroughly examined for performance, and any damaged cells will be clearly indicated in the data.

EVs, while not as mechanically intricate as ICE, rely on extremely high voltage electrical systems. If a repair is needed in this particular area of the vehicle, it may demand the expertise of a specialist. Our technicians have the relevant accreditation and experience to service your EV.

Car Servicing Similarities

Despite the contrasting engineering of electric vehicles and gas-powered vehicles, their maintenance requirements are remarkably similar, excluding powertrain-related aspects. Similar to traditional cars, EVs also require regular tyre rotations, either every 20K – 30K miles or annually. However, remember that the UKs minimum tread depth is 1.6mm across the middle ¾ of the width and around the whole of the tyre.

Additionally, they need their brakes serviced, the cabin air filter replaced, and the cooling system checked along with the suspension, steering linkages, tie-rod ends, and ball joints.
