How to Check MOT History: The Complete Guide

Whether you are buying a used car, checking on your own vehicle, or simply curious about a registration you have spotted, checking MOT history is one of the most important tools available to UK motorists. In this comprehensive guide, we explain everything you need to know about MOT history checks — how to do them, what to look for, and how to interpret the results.

What Is MOT History?

MOT history is the complete record of every MOT test a vehicle has undergone since records were digitised in 2005. Each entry includes the date of the test, whether the vehicle passed or failed, any defects or advisories recorded, and the odometer reading at the time of the test.

This data is maintained by the DVSA (Driver and Vehicle Standards Agency) and is publicly available to anyone with a vehicle registration number. The information is invaluable for understanding a vehicle's condition and maintenance history.

How to Check MOT History for Free

Checking MOT history is straightforward and takes just a few seconds:

1. Visit PlateCheck or download the free iOS app from the App Store.
2. Enter the vehicle registration number in the search box. This is the number shown on the vehicle's number plates.
3. View the results instantly. PlateCheck will display the complete MOT history along with tax status, mileage records, ULEZ compliance, and AI analysis.

You do not need to create an account, pay anything, or have the V5C logbook. Just the registration number is enough.

Understanding MOT Test Results

Each MOT test in the history will show one of three outcomes:

Pass

The vehicle met all required standards and is certified as roadworthy for another year. A pass may still include advisory items that do not cause failure but are noted for the owner's attention.

Fail

The vehicle did not meet one or more required standards and must be repaired before it can legally be driven on public roads. The specific defects that caused the failure will be listed in the test record.

Pass with Defects

Since May 2018, the MOT categorises defects into three levels: dangerous (most severe), major (causes failure), and minor (noted but does not cause failure). A vehicle can pass with minor defects recorded.

What to Look for in MOT History

When reviewing a vehicle's MOT history, there are several key things to pay attention to:

Mileage Progression

The mileage recorded at each MOT test should increase steadily over time. The average UK driver covers around 7,000 to 10,000 miles per year. Look for:

• Consistent yearly increases — this suggests normal, genuine use.
• Sudden drops in mileage — this is a major red flag indicating possible odometer tampering (clocking). If the mileage goes down between tests, the odometer may have been wound back.
• Unusually high mileage years — not necessarily bad, but worth understanding. A car that did 30,000 miles in one year may have been used as a taxi or delivery vehicle.
• Very low mileage — a car that barely moves can develop its own problems, including seized brakes, deteriorating seals, and flat-spotted tyres.

Recurring Defects

If the same issue appears across multiple MOT tests, it suggests either a persistent mechanical problem or a pattern of neglect. Pay particular attention to:

• Structural corrosion — rust that appears as an advisory or defect repeatedly may indicate a serious underlying problem that is progressing.
• Suspension issues — repeated suspension failures suggest the vehicle is being driven hard or that cheap, low-quality parts are being used for repairs.
• Brake problems — recurring brake defects could indicate a fundamental issue with the braking system rather than normal wear.

Gap Between Tests

If there is a long gap with no MOT test recorded, the vehicle may have been off the road (SORN), out of the country, or simply driven illegally without a valid MOT. Any unexplained gap is worth investigating.

Number of Retests

A vehicle that frequently fails its MOT and requires retests may have underlying reliability issues. While occasional failures are normal, a pattern of annual failures suggests the vehicle is only maintained to the minimum standard needed to pass.

MOT Defect Categories Explained

Since May 2018, MOT defects have been categorised into three severity levels:

• Dangerous: A direct and immediate risk to road safety or the environment. The vehicle must not be driven until repaired.
• Major: May affect safety, put other road users at risk, or have an impact on the environment. These cause an MOT failure and must be repaired.
• Minor: No significant effect on safety or the environment but should be repaired as soon as possible. These are recorded but do not cause failure.

Advisory items are separate from defects. They are notes about components that are in acceptable condition now but may deteriorate to the point of failure in the future. Advisories are useful for predicting upcoming maintenance costs.

How MOT History Helps When Buying a Used Car

The MOT history is one of the most powerful tools available to used car buyers. Here is how to use it effectively:

• Verify the seller's claims: If a seller says a car has low mileage, a clean history, or recent repairs, you can verify all of this through the MOT record.
• Estimate upcoming costs: Recent advisories tell you what is likely to need replacing soon. Factor these costs into your offer.
• Negotiate the price: Armed with knowledge of defects and advisories, you are in a much stronger position to negotiate a fair price.
• Compare vehicles: If you are choosing between similar cars, the MOT history can help you identify which has been better maintained.
• Detect fraud: Mileage clocking is a serious problem in the UK used car market. MOT mileage records are your best defence against odometer fraud.

Common MOT Failure Points

According to DVSA statistics, the most common reasons for MOT failure are:

1. Lighting and signalling (18%) — the most common cause of failure, usually due to blown bulbs or misaligned headlamps.
2. Suspension (13%) — worn shock absorbers, ball joints, and anti-roll bar links.
3. Brakes (10%) — worn pads, corroded discs, and fluid leaks.
4. Tyres (8%) — insufficient tread (below 1.6mm legal minimum), damage, or wrong size.
5. Visibility (7%) — windscreen damage in the swept area, faulty wipers, and missing mirrors.
6. Emissions (5%) — vehicles exceeding legal exhaust emission limits.

Understanding these common failures helps you assess what is normal wear versus genuine cause for concern when reviewing a vehicle's history.

Beyond MOT History: Complete Vehicle Checks

While MOT history tells you a lot about a vehicle's mechanical condition, it does not cover everything. For a complete picture, consider combining your MOT check with:

• Tax status check — confirm the vehicle is currently taxed and road-legal.
• Mileage analysis — our dedicated mileage check uses AI to detect anomalies in the odometer readings.
• ULEZ compliance check — essential if you drive in London or other Clean Air Zones.
• Vehicle history check — add stolen markers, finance verification, and write-off history for complete peace of mind.

All of these checks are available through PlateCheck. The core checks are completely free, with optional paid upgrades for advanced background data.

Conclusion

Checking MOT history is quick, free, and incredibly valuable. Whether you are buying a used car, monitoring your own vehicle, or helping a friend make a decision, the MOT record provides unparalleled insight into a vehicle's true condition and history.
