For many drivers, MOTs and car servicing can feel confusing or even unnecessary—until something goes wrong. Yet both play an important role in keeping your car safe, legal, and reliable. This article answers some of the most common questions drivers have about MOTs and servicing, helping you understand why they matter and how they work together.
What Is an MOT?
An MOT is a legal requirement in the UK for most vehicles over three years old. It checks whether your car meets minimum safety and environmental standards. During an MOT, testers inspect key components such as brakes, lights, tyres, steering, suspension, and emissions. Passing an MOT means your car is legally allowed on the road, but it doesn’t guarantee the vehicle is in perfect condition.
What Is a Car Service?
A car service is a routine maintenance check designed to keep your vehicle running smoothly. Unlike an MOT, servicing is not legally required, but it is strongly recommended. A service typically includes an oil change, filter replacement, fluid checks, and inspection of key engine components. Regular servicing helps identify wear and tear early, reducing the risk of breakdowns.
Do I Need Both an MOT and a Service?
Yes. An MOT ensures your car meets legal safety standards at the time of testing, while a service focuses on long-term performance and reliability. Skipping servicing may not affect your MOT immediately, but it can lead to problems that cause MOT failures later.
Can I Book an MOT and Service Together?
Many garages offer combined MOT and service appointments. This can save time and money, as technicians can address issues during the service before the MOT test begins. It also reduces the risk of failing due to minor, preventable faults.
Does a Failed MOT Mean My Car Is Unsafe?
Not always. Some MOT failures are minor, such as worn tyres or faulty bulbs. However, serious faults should be fixed immediately. Regular servicing helps reduce the chance of unexpected MOT failures.
How Often Should I Service My Car?
Most manufacturers recommend servicing once a year or every 10,000–12,000 miles. Check your owner’s manual for specific guidance.
Final Thoughts
Understanding MOT and service requirements helps drivers make smarter decisions. Together, they keep your car safe, legal, and dependable—giving you confidence every time you drive.
