The annual MOT test is a legal requirement for vehicles in the UK that are over three years old, ensuring they meet road safety and environmental standards. However, many car owners dread the test, fearing costly repairs and unexpected failures. The good news? With some insider knowledge and proactive steps, you can significantly reduce your MOT costs and improve your chances of passing on the first attempt.

We spoke to experienced mechanics and industry experts to compile the best tips on how to save money on your MOT while keeping your vehicle in top shape.

1. Conduct Pre-MOT Checks Yourself

One of the simplest ways to avoid unnecessary MOT failures is to carry out basic checks before taking your car to the test centre. Many faults flagged during an MOT are minor and can be fixed cheaply or even for free at home.

Things to check:

• Lights & Indicators – Ensure all bulbs are working. Check headlights, brake lights, indicators, and number plate lights.
• Tyres – The legal minimum tread depth is 1.6mm across the central three-quarters of the tyre. Ensure all tyres are properly inflated.
• Windscreen Wipers & Washers – Replace worn wiper blades and ensure washer fluid is topped up.
• Brakes – Listen for unusual noises and test brake responsiveness.
• Mirrors & Number Plates – Ensure they are secure and clean.

These simple checks can help you avoid failing due to minor issues that you could have fixed yourself.

2. Address Advisory Notes from Previous MOTs

Each MOT test provides not just a pass or fail but also advisory notes on potential future problems. These are not immediate failures but indicate components that are wearing out and may cause an issue in the future.

Why this matters: If an advisory was noted last year, it could worsen by the next MOT, leading to costly repairs. Dealing with these issues early can prevent an expensive failure. You can check your previous MOT history online at the official government website.

3. Consider a Council MOT Test Centre

Most MOT test centers are garages that also offer repairs, which can sometimes lead to unnecessary recommendations. If you’re concerned about being upsold repairs, consider a council-run MOT center. These facilities only conduct tests and do not carry out repairs, reducing any potential conflict of interest.

4. Book Your MOT and Service Together

A great way to save money is by combining your MOT with an annual service. Many garages offer discounted MOTs when booked with a service, as they can check and fix potential issues beforehand.

Benefits of combining MOT and service:

• Fix issues before the test, reducing failure risk.
• Save on labour costs by bundling services.
• Improve your vehicle’s overall performance and longevity.

Always compare local garages to find the best combined service and MOT deals.

5. Fix Minor Issues Yourself

While some repairs require a professional mechanic, many minor issues can be fixed at home with basic tools.

Common DIY repairs:

• Replacing bulbs (headlights, indicators, brake lights).
• Changing wiper blades.
• Topping up fluids (oil, coolant, washer fluid).
• Checking and inflating tyres.

Doing these simple fixes yourself can save on labour costs and prevent minor failures that require a retest.

6. Choose the Right MOT Test Centre

MOT test fees are capped by law, but prices vary between garages. The maximum fee for a standard car MOT is £54.85, but many garages offer discounts.

How to find the best price:

• Use price comparison websites.
• Look for special offers from local garages.
• Ask about discounts when booking with a service.

7. Drive Smoothly to Reduce Wear and Tear

Your driving habits have a direct impact on how quickly components wear out. Harsh acceleration, braking, and cornering put extra strain on your brakes, tyres, and suspension, increasing the likelihood of costly repairs.

Best practices to extend your car’s lifespan:

• Accelerate and brake gently.
• Shift gears smoothly.
• Avoid potholes and rough roads when possible.

8. Use Free Vehicle Health Checks

Many garages and dealerships offer free vehicle checks, which can help identify potential MOT failures in advance. Major companies like Halfords, Kwik Fit, and National Tyres often provide free safety checks, including:

• Tyre tread depth and pressure.
• Battery health.
• Brake inspections.

Taking advantage of these free checks can help you prepare for your MOT without spending extra money.

9. Address Dashboard Warning Lights Promptly

If your dashboard displays warning lights, your car will likely fail its MOT. Common warnings include:

• Engine management light (EML).
• ABS warning light.
• Airbag or SRS light.

Ignoring these lights could lead to a costly failure. A quick diagnostic check at a local garage (or using an OBD2 scanner at home) can help pinpoint and fix the issue before the test.

10. Plan Your MOT in Advance

Leaving your MOT to the last minute can be risky. If your car fails, you’ll need time for repairs before the current certificate expires.

Why book early?

• Gives time to fix issues before retesting.
• Allows flexibility in choosing the best test centre.
• Avoids last-minute price hikes from busy garages.

You can book your MOT test up to one month (minus a day) before your current certificate expires without losing any days on the new certificate. Check your MOT expiry date and book in advance here.

Conclusion

Saving money on your MOT doesn’t have to be difficult. By performing simple pre-MOT checks, fixing minor issues yourself, and booking strategically, you can reduce costs and increase your chances of passing on the first attempt.

The key takeaway? Prevention is always cheaper than repair regular maintenance and early issue detection will help keep your car roadworthy and your MOT bill low.
