How to check a vehicle's MOT history and what gaps might mean

Checking a vehicle's MOT history is one of the quickest ways to learn more about its condition and how it has been maintained.

For anyone buying a used car, MOT records can highlight recurring faults, reveal patterns of neglect and help identify areas that may need attention in the future.

How to check MOT history

You can check a vehicle's MOT history free of charge using the Government's MOT history service.

You'll need:

• The vehicle registration number

The service allows you to:

• Check whether the MOT is currently valid
• View previous MOT results
• Review advisory notices
• See recorded failures and defects

Always use the official GOV.UK service when checking MOT records.

What can you learn from MOT history?

MOT records provide much more than a simple pass or fail result.

Depending on the vehicle's history, you may be able to see:

• Previous failures
• Advisory notices
• Mileage recorded at each test
• The date of each MOT

Before reviewing the results, make sure the vehicle details shown match the car you're looking at.

The MOT checker displays information including:

• Make
• Model
• Colour

If these details do not match the vehicle, stop and investigate further.

Why advisories matter

Advisories often provide the most useful information when assessing a used vehicle.

They can highlight developing issues such as:

• Tyres approaching the legal tread limit
• Brake wear
• Corrosion
• Oil leaks
• Windscreen damage

A single advisory is not necessarily a concern.

However, repeated advisories over several years can indicate that issues are being left unresolved.

What do gaps in MOT history mean?

A gap in MOT history does not automatically indicate a problem.

Tony Rich, former AA Patrol of the Year, says buyers: "Shouldn't read into too much into gaps in history and should instead focus on the advisories."

There are several legitimate reasons why an MOT record may contain gaps.

The vehicle was off the road

The vehicle may simply not have been used.

Examples include:

• Seasonal vehicles
• Convertibles used mainly in summer
• Vehicles placed in storage
• Cars undergoing restoration or repair

The vehicle was held in stock

Some dealers may keep vehicles off the road before sale and arrange a fresh MOT when a buyer is found.

Administrative reasons

In some cases, owners may simply have delayed booking an MOT or not used the vehicle for a period of time.

A gap on its own rarely tells the full story.

How to assess risk when reviewing MOT history

Focus on the most recent MOT

The latest MOT often provides the clearest picture of the vehicle's current condition.

Review:

• Advisories
• Defects
• Previous failures
• Mileage progression

This information can help identify likely future maintenance costs.

Look for recurring issues

Repeated advisories can reveal long-term problems.

Pay particular attention to recurring references to:

• Corrosion
• Brake wear
• Suspension wear
• Tyres

If the same issue appears year after year, it may indicate that repairs have been delayed or only partially addressed.

Compare old and new MOTs

One useful approach is to compare the most recent MOT with earlier tests.

Ask yourself:

• Have previous advisories disappeared?
• Have faults been repaired?
• Are the same issues being reported repeatedly?

A vehicle whose advisories are consistently addressed may suggest more diligent maintenance.

Questions to ask the seller

If the MOT history raises concerns, ask direct questions.

For example:

• Why was there a gap in testing?
• Were previous advisories repaired?
• Is there evidence of work being carried out?

A genuine seller should usually be able to explain major gaps or provide supporting paperwork.

Check MOT history alongside service history

MOT history and service history work best when viewed together.

An MOT shows the condition of the vehicle at the time of testing.

A service history helps demonstrate whether routine maintenance has been carried out in line with manufacturer recommendations.

When reviewing both records, consider:

• Whether servicing has been carried out at the correct intervals
• Whether advisory items appear to have been repaired
• Whether maintenance records support the vehicle's condition

Together, they provide a more complete picture than either record alone.

What should raise concern?

While MOT gaps are not necessarily a problem, some patterns deserve closer attention.

Examples include:

• Repeated corrosion advisories
• Persistent brake or tyre warnings
• Frequent failures for the same fault
• Large unexplained mileage changes
• A complete lack of service records

These do not automatically mean you should walk away, but they should prompt further questions before buying.
