MOT First? Save Billions on Car Maintenance

Car ownership in the UK comes with its share of responsibilities, and among the most significant are the annual MOT test and regular vehicle servicing. For many motorists, these two essential appointments can feel like a drain on the bank account, especially when unexpected faults are uncovered. However, what if there was a simple, strategic change to your maintenance schedule that could save you a substantial amount of money? Recent research suggests that by simply reversing the order in which you undertake these vital checks, you could be saving billions across the country, avoiding costly duplicated work.

The Costly Overlap: Unnecessary Duplication of Checks

It’s a scenario many of us have faced: you book your car in for its annual service, anticipating a routine check-up, only to be hit with a bill for various repairs. Then, shortly after, comes the MOT test, which often flags some of the same issues. This isn't just frustrating; it's financially inefficient. A groundbreaking study by car repair start-up Motoreasy revealed a striking truth: approximately 80% of issues identified during a standard car service would also be picked up as part of the mandatory MOT test.

This significant overlap means that mechanics are often performing duplicated work, checking components that have already been scrutinised (or will be) during the MOT. Considering that the average hourly labour rate in the UK is around £77, and an MOT test typically takes about an hour, this duplication can lead to unnecessary expenditure for the motorist. With nearly 29 million MOT tests conducted annually, the potential savings nationwide are staggering – an estimated £2.2 billion in labour costs that could be entirely avoided.

Understanding the MOT Test: More Than Just a Legal Requirement

The MOT (Ministry of Transport) test is a legal requirement for most vehicles over three years old in the UK. Its primary purpose is to ensure that vehicles meet minimum road safety and environmental standards. It is not a service and doesn't involve replacing parts or fluids; rather, it’s an inspection. The MOT test rigorously checks several critical areas of your vehicle to ensure it is roadworthy:

• Bodywork and Vehicle Structure: Including corrosion, damage, and sharp edges.
• Steering: Condition and operation of the steering wheel and column.
• Suspension: Dampers, springs, and linkages for wear and damage.
• Brakes: Efficiency, condition, and operation of all braking components.
• Tyres and Wheels: Condition, size, and tread depth.
• Lights: Operation, condition, and alignment of all lights.
• Seatbelts: Condition and operation of all seatbelts.
• Windscreen Wipers and Washers: Ensuring clear visibility.
• Exhaust System and Emissions: Checking for leaks and excessive pollutants.
• Fuel System: For leaks and secure mounting.
• Horn: Operation.

The comprehensive nature of these checks means that any significant safety-related faults, such as issues with your brakes, tyres, lights, or suspension, are highly likely to be identified during an MOT. These are precisely the kinds of problems that often lead to costly repairs during a service if not caught earlier.

What a Car Service Entails: Beyond the MOT's Scope

While an MOT focuses purely on safety and environmental standards, a car service is designed to maintain your vehicle's overall health and performance. It involves preventative maintenance and typically includes:

• Oil and Filter Changes: Essential for engine lubrication and cleanliness.
• Fluid Level Checks and Top-ups: Including coolant, brake fluid, power steering fluid, and windscreen wash.
• Spark Plug Replacement: For optimal engine combustion.
• Air and Fuel Filter Replacements: To ensure clean air and fuel supply to the engine.
• General System Checks: Such as checking for hidden leaks, inspecting the gearbox oil, and assessing the wear and tear of various components that might not immediately impact safety but are crucial for longevity.

The key difference is that a service proactively addresses wear and tear and maintains performance, whereas an MOT is a snapshot inspection of current roadworthiness. However, as the research shows, many of the common service items that relate to safety, such as windscreen wipers, lights, suspension parts, tyres, and brakes, are already thoroughly examined during the MOT.

The Financial Impact: Why Timing Matters

The financial implications of getting your MOT before your service are substantial. If your vehicle fails its MOT, you'll know precisely what needs fixing to make it roadworthy. These are typically the most urgent and safety-critical repairs. By addressing these first, any subsequent service will then focus solely on the preventative maintenance items that the MOT doesn't cover, such as fluid changes or filter replacements. This strategic approach avoids paying for a mechanic to spend time diagnosing issues during a service that an MOT would have already identified for a fixed, statutory fee.

Consider the average hourly labour rate of £77. If a service takes an hour to identify issues that the MOT would have found, you're effectively paying £77 for information you could have received through the MOT, which has a maximum statutory fee of £54.85 for cars and motorbikes. This simple shift in scheduling could save you, on average, a significant portion of your service bill.

Urgency and Accuracy: The MOT's Edge

Motoreasy also highlighted another crucial point: the MOT test is often a more reliable indicator of faults that genuinely require urgent attention. While no system is perfect, their data suggested that MOT testers are twice as likely to pass a car that should have failed (19.3%) than to erroneously fail a car (8%). This means that if your vehicle fails its MOT, it's highly probable that it has a genuine fault that requires immediate rectification for safety reasons. This focus on critical safety items ensures that any repair work you undertake post-MOT is genuinely necessary and prioritised.

Strategic Planning for Savvy Motorists

Duncan McClure Fisher, founder of Motoreasy, strongly advises drivers to be strategic about their maintenance schedules, especially when using the same garage for both their MOT and service. He notes, "The problem is that, even if you get faults repaired as a result of the service, you’ll still have to pay for the MOT anyway because that is a legal obligation for all vehicles. So, when booking the two together, you should always request that the MOT is done first so that there is less work to carry out on the service."

This advice is particularly pertinent because the MOT is a pass/fail test with clear criteria, whereas a service can sometimes be more subjective in terms of what constitutes a "fault" requiring immediate attention versus preventative maintenance. By getting the MOT done first, any identified failures must be rectified to make the vehicle road legal. The subsequent service can then focus on the non-MOT related items, ensuring you're paying for genuinely separate and necessary work.

Where Are Labour Costs Highest?

The cost of vehicle maintenance can vary significantly across the UK, largely due to differences in labour rates. Motoreasy's analysis of labour costs reveals a clear geographical disparity. Knowing where your area stands can further highlight the importance of optimising your maintenance schedule to avoid unnecessary expenses.

As you can see, areas like Surrey and London command significantly higher hourly rates, making any duplicated labour even more costly. This table underscores the financial incentive for motorists in these regions, and indeed across the entire UK, to be more strategic about their vehicle maintenance appointments.

Frequently Asked Questions (FAQs)

Q1: What is the primary difference between an MOT and a car service?

An MOT is a legal inspection to ensure your vehicle meets minimum safety and environmental standards at the time of the test. It's a pass/fail assessment. A car service, on the other hand, is preventative maintenance that involves checking, topping up, or replacing fluids, filters, and other wear-and-tear components to keep your car running efficiently and reliably over time. It's about maintaining performance and longevity, not just legal compliance.

Q2: Is it legally required to have a car service?

No, unlike the MOT, a car service is not a legal requirement. However, it is highly recommended by manufacturers and mechanics to ensure the longevity, safety, and efficiency of your vehicle. Neglecting regular servicing can lead to more significant, costlier problems down the line and may even invalidate your vehicle's warranty.

Q3: Can I fail my MOT for minor issues?

An MOT test categorises faults as "minor," "major," or "dangerous." Your car will only fail if it has "major" or "dangerous" defects. Minor defects are advisory and do not result in a fail, but they should be rectified as soon as possible. The research mentioned suggests that if your car fails, it's usually for a genuine, significant fault.

Q4: How long does an MOT test typically take?

An MOT test usually takes between 45 to 60 minutes. However, garages may require your car for longer to complete the paperwork and allow for any necessary re-tests or minor adjustments if issues are found.

Q5: What should I do if my car fails its MOT?

If your car fails its MOT, you will receive a 'Refusal of an MOT Test Certificate' form detailing the reasons for failure. You cannot drive your car on the road until the 'major' or 'dangerous' faults are repaired and it passes a retest, unless you are driving it to a pre-booked appointment for repairs or to a pre-booked MOT retest. Many garages offer a free or reduced-price retest if the repairs are done at the same garage within a certain timeframe.

Conclusion: A Smarter Approach to Car Care

In conclusion, the evidence strongly supports a strategic shift in how UK motorists approach their annual vehicle maintenance. By prioritising your MOT test before your car service, you can effectively leverage the legal inspection to identify crucial safety-related faults without incurring additional labour costs for duplicated checks during a service. This intelligent sequencing not only has the potential to save you, and indeed the nation, billions of pounds in unnecessary expenditure but also ensures that any urgent safety issues are identified and addressed first. It’s about being a savvy motorist, making your money work harder, and ensuring your vehicle remains safe and roadworthy without breaking the bank. So, next time you book your car in, remember: MOT first, then service.
