Car servicing: How to keep your car in top condition

Want your car to run smoothly and safely for as long as possible? You’ll need to take extra special care of it. Regular servicing can help you do this.

What is a car service?

Car servicing is essentially when a professional provides a comprehensive health check of your vehicle. It will help keep your vehicle safe to drive, assessing its brakes, engine, fluids and general condition.

Regular services can help keep your car running, prevent future issues and extend how long it lasts (while also keeping its value). The type of service you choose depends on how many miles you’ve driven and the age and state of your vehicle.

What is a car’s service history, and why is it important?

Your car service history is a complete record of the maintenance and repair work that has been carried out since it was manufactured. It shows the vehicle has been well maintained and could increase its resale value. A physical book or digital record, it can also help ensure the manufacturer’s warranty is valid.

What are the different types of car service?

Although it may differ between garages, there are typically three types of car service:

  • Interim service
  • Full service
  • Major service

What is an interim service?

An interim service is recommended every 6 months or 6,000 miles, whichever comes first. This service is particularly beneficial for high-mileage drivers, (Halfords recommends it for those who drive 2,000 miles or more per month), as they may require more than one service a year to maintain their vehicle's condition.

An interim service is designed to keep cars roadworthy in-between the annual, more in-depth services. A mechanic will check steering, suspension and tyres but this is not a replacement for a full service. An interim service tends to include:

  • Interior checks - Checking the lights, seat belts, horn, windscreen wipers, manual clutch operation and vehicle diagnostics for any errors.
  • Exterior checks - Are the doors and boot opening and closing properly? Is the petrol cap tight enough?
  • Under-the-bonnet checks - Is the battery working ok and all wiring still in place. Electrics and brake fluids will also be checked.

A mechanic might also change your oil, replace your oil filter and inspect a drive belt but this could vary between garages.

What is a full service?

Recommended every 12 months or 12,000 miles, a full car service is a more comprehensive annual check with some preventative maintenance. During a full service, a mechanic will make up to 80 checks to ensure your car is safe and roadworthy.

A full service can help your car run better by identifying problems before they get worse. A mechanic will look at the most important components of your car, ensuring the safety and mechanical systems are in working order and that your car is performing to its highest standard.

What does a full car service include?

  • Engine and oil - Check for leaks, change the oil, replace the filter.
  • Fluids - Check and top up brake fluid, coolant and screen wash.
  • Filters - Replace the air filter.
  • Brakes - Inspect pads, discs and your handbrake.
  • Tyres and wheels - Check the condition, tread dept, pressure, and alignment.
  • Steering and suspension - Controls, components and shock absorbers.
  • Lights, electrics and engine diagnostics - Check all internal and external lights are working, test the horn, examine the battery condition, and ensure codes are working.
  • Exhaust system - Check for damage or leaks.
  • Battery - How much charge does it have left?

They’ll also look at your windscreen, wipers, mirrors, seat belts, and assess bodywork for damage, which you can arrange to be repaired separately. Additional checks could also include air con, exhausts and fuel pipes.

Full services are often booked in at the same time as an MOT test.

What is the average cost of a full car service?

This will vary between type of service, vehicle and garage but the RAC claims the average cost for a full service is between £170 and £300.

What is a major service?

In a major service, a mechanic will provide a comprehensive check of your car, as they do in an annual service, but also check and change parts that need replacing on a longer-term basis e.g. brake fluid. It’s recommended you book a major service every two years or 24,000 miles - again, whichever one comes first.

According to The AA’s car servicing complete guide, major service checks to your car might include:

  • Brake fluid replacement
  • Odour and allergy filter replacement
  • Spark plugs replacement
  • Automatic transmission oil level inspection
  • Test battery

As an example of what individual garages may offer, Arnold Clark’s major service also includes:

  • Checking air con works effectively
  • Adjusting any misaligned wheels
  • Fitting air filters, spark plugs and fuel filters

If you own a higher-specification or more expensive model, you may need a manufacturer’s service. You can find out when this will be in your handbook.

In this service, mechanics will adhere to individual manufacturer service schedules and may only use official parts and fluids. It will normally be carried out at the dealership where you sold the car and can be more expensive.

How often should I service my car?

Although there is no legal requirement, many manufacturers recommend you service your car at least once a year, or after you’ve driven 12,000 miles. If you are a high-mileage driver, you can consider an interim service.

Where can I service my car?

There are a few options when it comes to servicing your car:

  • Independent garage: Often the convenient and affordable option, local and independent garages can carry out servicing on your cars. Check out online reviews and speak to others who have used them to confirm their reputation.
  • Mobile mechanic: A qualified professional can come to your home or workplace and carry out the service.
  • Dealership: If your car is under warranty, you may be able to get services at a dealership. These are also suitable if you have a high-end car and are looking to use genuine parts for any replacements.

What are the differences between an MOT and service?

  • An MOT is a test that confirms your car is in roadworthy condition. Your car must pass this on an annual basis.
  • A service is a comprehensive maintenance check that ensures your car is in working order.

Can I have an MOT without a service?

Yes, you legally need to pass an MOT test every year, but you do not need to put your car through a service. However, it is recommended that your car goes through an annual service to keep it in tip-top condition.

Why is a service more expensive than an MOT?

Services cost more than MOTs because they are more thorough maintenance checks. A service has many more checks than an MOT and can include replacement of fluids and other car parts.

It’s important to keep on top of regular servicing of your vehicle. Ideally, you should have your car serviced at least once a year - and maybe more if you are a high-mileage driver. You could alternate between full and major services or refer to the manufacturer’s recommendations.

When it’s time to take the car into a garage, ensure you take it to a trusted mechanic. Shop around and do your research before taking your car in. It’s so important to keep your car moving and avoid any unnecessary costs.
