What Is an MOT History Check?

An MOT history check allows you to view a vehicle's previous MOT records, including passes, failures, advisories, recorded defects, mileage readings and MOT expiry dates.

Checking the MOT history is one of the most important steps when buying a used car. It can reveal recurring faults, highlight likely repair costs and help you understand how well the vehicle has been maintained over time.

You can use our Free MOT History Check to review a vehicle's MOT records using official DVSA MOT data.

What Information Does an MOT History Check Show?

An MOT history check provides a chronological record of a vehicle's previous MOT tests.

It typically shows:

This information can provide valuable insight into the vehicle's condition, maintenance history and possible future repair requirements.

An MOT history check does not replace a mechanical inspection or full service history. However, it gives you a useful evidence-based starting point before viewing or buying a vehicle.

What an MOT history check cannot show

An MOT history does not confirm whether every advisory was repaired, whether the vehicle has been serviced correctly or whether it currently has faults that were not present during its last MOT. Always consider the MOT record alongside the service history, current condition and an independent inspection.

Why Is MOT History Important?

Many used cars look clean and well-presented during a viewing but may have underlying problems that are not immediately obvious.

An MOT history check can help identify:

One isolated advisory is not usually a major concern. However, the same issue appearing across several MOT tests may suggest that repairs have been delayed, the underlying cause has not been resolved or the vehicle has been maintained to a limited standard.

The overall pattern matters more than one individual test result.

What Are MOT Advisories?

MOT advisories are warnings recorded by the MOT tester when a component is worn, deteriorating or likely to require attention in the future.

The vehicle can still pass its MOT because the issue has not reached the threshold for failure.

Common advisories include:

Advisories should not automatically put you off buying a vehicle. A few age-related advisories are common, particularly on older or higher-mileage cars.

The more important questions are:

Can MOT Mileage Records Help Spot Problems?

Yes.

Mileage readings recorded during MOT tests can help you assess whether a vehicle's mileage history appears consistent.

Each test normally includes the mileage shown on the vehicle's odometer at the time of inspection. Reviewing these readings in date order can reveal unusual patterns.

Potential warning signs include:

A mileage discrepancy does not automatically prove that a vehicle has been clocked. Data-entry mistakes, replacement instrument clusters and unit changes can also create inconsistencies.

However, any unexplained difference should be investigated before buying.

⚠️ Do not rely on mileage alone

A consistent MOT mileage history is reassuring, but it does not guarantee that the displayed mileage is genuine. Compare MOT records with service invoices, maintenance receipts, previous adverts and the vehicle's physical condition.

What Should You Look For When Buying a Used Car?

When reviewing a vehicle's MOT history, do not focus only on whether the latest test was a pass.

Look at the complete record and identify patterns across several years.

Repeated Advisories

The same advisory appearing year after year may suggest that the issue has not been repaired.

Repeated warnings involving tyres, brakes, suspension or corrosion deserve particular attention because they may indicate delayed maintenance or an unresolved underlying problem.

A repeated advisory can also help you estimate which repairs may be required soon.

Brake and Tyre Issues

Brake and tyre advisories can indicate upcoming maintenance costs.

Look for references to:

Uneven tyre wear can sometimes indicate poor wheel alignment, worn suspension or incorrect tyre pressures rather than a problem with the tyre alone.

Corrosion

Corrosion advisories can range from minor surface rust to deterioration that may later affect structural areas or brake pipes.

One mild corrosion advisory on an older vehicle may not be unusual. Repeated or worsening corrosion warnings are more concerning, particularly when they involve:

Corrosion repairs can become expensive if cutting, welding or replacement components are required.

MOT Failures

A previous MOT failure does not automatically mean the vehicle is unreliable.

Many cars fail for relatively straightforward reasons such as:

What matters is the type of defect, whether it was repaired and whether the same problem returned later.

Repeated failures for the same safety-related issue may indicate poor maintenance or an unresolved fault.

Dangerous or Major Defects

Pay close attention to any previous major or dangerous defects.

A major defect causes an MOT failure because it may affect safety, the environment or other road users. A dangerous defect represents a direct and immediate road-safety risk.

A properly repaired historical defect is not necessarily a reason to reject the vehicle. However, repeated serious defects should prompt closer inspection.

Gaps in MOT History

A gap between MOT tests may have a reasonable explanation, such as the vehicle being declared SORN, kept off the road or used outside the UK.

However, unexplained gaps should be discussed with the seller, especially when the service history is also incomplete.

How to Interpret an MOT History

An MOT history should be assessed as a pattern rather than a simple list of passes and failures.

A strong history may include:

A weaker history may include:

At a glance

Repeated age-related advisories
Ask for evidence of maintenance and budget for repairs
Recurring brakes, tyres or suspension issues
Arrange an independent inspection
Mileage inconsistencies or repeated serious defects
Investigate fully before making an offer
Dangerous defects with no repair evidence
Do not proceed until the vehicle is professionally checked

A vehicle does not need a perfect MOT history to be a good purchase. Older cars naturally develop wear, and even well-maintained vehicles can receive advisories.

The key is whether problems were dealt with responsibly.

Does an MOT History Check Show Service History?

No.

An MOT history check and a service history are different records.

An MOT test checks whether a vehicle meets minimum legal safety and environmental standards at the time of the inspection.

A service involves routine maintenance and may include:

A vehicle can have a clean MOT history but a poor service history. It can also have a good service record while occasionally failing an MOT for worn or defective parts.

For the clearest picture, review both records.

Can You Check the MOT History of Any Vehicle?

You can normally check the MOT history of a UK vehicle using its registration number.

The available information depends on the vehicle and the records held by the DVSA.

Some vehicles may have limited or no visible history because:

A missing history does not automatically mean there is a problem, but it should be investigated before purchase.

The data is based on official DVSA MOT records.

You do not need the vehicle identification number or the seller's permission to carry out a standard MOT history check.

Can an MOT History Check Tell You Whether to Buy a Car?

It can help you make a better decision, but it cannot make the decision for you.

An MOT history is useful because it provides an independent record of defects observed during previous tests. It can help you identify risks, ask better questions and negotiate based on likely repair costs.

However, it does not show:

Frequently Asked Questions

Is an MOT history check free?

Yes. You can check a vehicle's MOT history, advisories, failures and mileage records free of charge using its registration number.

Does an MOT advisory mean a car is bad?

Not necessarily. Advisories identify wear or deterioration that was not serious enough to cause an MOT failure. Minor advisories are common, particularly on older vehicles.

Repeated or safety-related advisories require closer attention.

Can I check MOT history before buying a car?

Yes. Checking the MOT history before buying a used car is strongly recommended.

It can reveal recurring faults, previous failures, mileage inconsistencies and likely repair costs before you commit to the purchase.

Does MOT history show mileage?

Yes. The mileage recorded at each MOT test is normally included in the vehicle's MOT history.

These readings can help you identify unusual changes or inconsistencies.

Does a previous MOT failure mean I should avoid the car?

No. A previous failure is not automatically a reason to avoid a vehicle.

Consider why it failed, whether the defect was repaired and whether the same issue returned in later tests.

Can an MOT history be changed?

Official MOT records are retained by the DVSA. Genuine errors may sometimes be corrected through the appropriate process, but a seller cannot simply remove an unfavourable MOT result.

Does a valid MOT mean the car is safe?

A valid MOT confirms that the vehicle met the required standards when it was tested. It does not guarantee that the vehicle is still free from defects or will remain roadworthy for the full 12 months.

How far back does an MOT history check go?

The amount of history available depends on the vehicle and the records held digitally. Many vehicles have records covering several years, allowing you to identify long-term patterns.

What should I do if the mileage is inconsistent?

Ask the seller for an explanation and compare the MOT readings with service invoices, maintenance records and previous sale documents.

Do not proceed until you understand the reason for the discrepancy.

Final Thoughts

An MOT history check is one of the most useful tools available to used-car buyers.

By reviewing previous MOT records, advisories, failures, defects and mileage readings, you can better understand how the vehicle has been maintained and identify possible repair costs before buying.

A clean MOT history does not guarantee a fault-free car, and an imperfect history does not automatically make a vehicle a bad purchase. The important factors are the type of problems recorded, whether they were repaired and whether the same issues continued to return.
