A Guide to Car Services and MOTs

Owning a car comes with responsibilities, and two of the most important things to keep your vehicle in top condition are car services and MOTs. You might be wondering what these terms mean, how they differ, and why they matter. This guide will break it all down for you in a simple and informative way.

What is an MOT?

An MOT (Ministry of Transport test) is a legal requirement for most vehicles over three years old. It is an annual inspection that ensures your car meets road safety and environmental standards. Without a valid MOT certificate, your car is not legally allowed on the road, and you could face a fine of up to £1,000.

What Does an MOT Check?

An MOT test includes an inspection of key components such as:

  • Brakes and brake systems
  • Lights and indicators
  • Tyres and wheels (including tread depth and condition)
  • Suspension and steering
  • Exhaust emissions
  • Seatbelts and airbags
  • Windscreen, wipers, and mirrors

The test does not check the engine, clutch, or gearbox, as these are covered in a car service.

If your car passes, you’ll receive an MOT certificate valid for 12 months. If it fails, you’ll be given a list of necessary repairs before your car can be deemed roadworthy again.

What is a Car Service?

A car service is not legally required, but it is highly recommended to keep your car running smoothly and efficiently. Unlike an MOT, which ensures legal roadworthiness, a service is focused on preventative maintenance to extend your car’s lifespan and performance.

Types of Car Services

There are different levels of car servicing available, depending on how frequently you drive and the manufacturer’s recommendations:

1. Interim Service (Every 6 months or 6,000 miles)

A basic check-up that includes:

  • Oil and filter change
  • Brake checks
  • Tyre and tread inspection
  • Top-up of essential fluids
  • General safety inspection

2. Full Service (Every 12 months or 12,000 miles)

A more in-depth service that includes:

  • All interim service checks
  • Air and fuel filter replacements
  • Battery and charging system checks
  • Cooling system inspection
  • Steering and suspension checks

3. Major Service (Every 24 months or 24,000 miles)

The most comprehensive service, covering:

  • Everything from a full-service
  • Brake fluid replacement
  • Transmission fluid check
  • More detailed inspections of key components

Regular servicing helps you avoid expensive breakdowns, improves fuel efficiency, and maintains the value of your car.

Why Do You Need Both an MOT and a Service?

While some people assume an MOT is enough, the reality is that an MOT only checks for roadworthiness—it does not include maintenance or repairs. A service ensures your car stays in peak condition, reducing the risk of failures and costly repairs in the long run. Together, they keep your car safe, reliable, and running efficiently.

How to Prepare for an MOT or Service

Before taking your car in, follow these simple steps to increase the chances of passing an MOT and make your service smoother:

  • Check your lights – Make sure all indicators, brake lights, and headlights work.
  • Inspect your tyres – Ensure they have at least 1.6mm tread depth and are properly inflated. Top up essential fluids – Oil, brake fluid, coolant, and screen wash.
  • Clean your car – A dirty or cluttered car could lead to a test refusal.
  • Check your wipers and horn – Both must function properly to pass an MOT.

For a service, make sure to inform the garage of any concerns you’ve noticed, such as strange noises, warning lights, or performance issues.

How Much Do an MOT and Service Cost?

  • MOT test – Typically £54.85
  • Servicing Prices - Situational and will vary per vehicle

Final Thoughts

Understanding MOTs and car servicing is essential for safe, efficient, and cost-effective vehicle ownership. While an MOT ensures your car meets legal roadworthiness, regular servicing keeps it running at its best. Scheduling both at the right intervals will save you money in the long run and help prevent breakdowns.

If your MOT is due, why not book a service at the same time? It’s a smart investment in your car’s health and safety.
