How to check a car's MOT history (free)

A car's MOT history is one of the most honest records you can read before buying. It shows every test the vehicle has taken, what passed, what failed and what an inspector flagged as a concern — all for free, straight from the government. Here is how to check it and, more importantly, how to make sense of what you find.

What the MOT history actually shows

Every time a car over three years old is MOT tested in England, Scotland or Wales, the result is recorded on the DVSA's central database. When you look up a vehicle you can see, for each test:

• The result — a straightforward pass or fail on the day of the test.
• The mileage — the odometer reading the tester recorded at that visit.
• Advisories — items that are still legal but starting to wear and worth monitoring.
• Failure items — the specific defects that caused a fail, listed by category.

Taken together, these entries build a timeline of how the car has been treated across its life. A single test tells you little; the pattern across five or ten years tells you a great deal.

How to read it on the official gov.uk service

The check itself takes under a minute:

1. Search for the gov.uk service "Check the MOT history of a vehicle" and open the official page (the address ends in gov.uk — avoid look-alike sites).
2. Enter the vehicle's registration number and confirm the make and model shown match the car you are looking at.
3. Browse the list of tests, newest first. Expand each one to see the mileage, any advisories and any failure items in full.

You do not need to create an account or pay anything. If the make and model on screen do not match the car in front of you, treat that as a serious warning — the plates may not belong to the vehicle.

Advisories, majors and dangerous faults

Since 2018 the MOT has graded defects, and knowing the difference matters when you read a report:

• Advisory — not a failure. Something is wearing and will likely need attention before long, such as a tyre approaching the legal limit. The car still passes.
• Minor — a small fault that does not affect safety. The car passes, but the fault should be repaired.
• Major — a defect that could affect safety or the environment. This causes an automatic fail.
• Dangerous — a defect that presents a direct risk. It fails, and you must not drive the car until it is fixed.

A one-off major that was fixed and passed on retest is normal wear and tear. What deserves closer attention is the story the advisories tell over time.

How recurring advisories reveal neglect

The same advisory appearing year after year is a quiet signal that a car has been run to the bare minimum rather than properly maintained. Watch for repeating notes about:

• Tyres — advisories for tread "close to the legal limit" flagged repeatedly suggest the owner replaced tyres late, or not at all.
• Brakes — recurring mentions of worn discs, pads or binding brakes point to deferred servicing.
• Corrosion — advisories about rust on the sills, subframe or brake lines that come back each year mean the problem is spreading, not stable.

One advisory is routine. The same one three years running is a pattern, and patterns tell you how the previous owner made decisions about spending money on the car.

Using mileage readings to spot clocking

Every MOT records the odometer reading, which gives you a series of mileage snapshots stretching back years. In a normal history the mileage climbs steadily. What should stop you is a reading that goes down, or a sudden collapse in the yearly distance covered — for example a car doing 12,000 miles a year that suddenly appears to do 2,000.

"Clocking" — winding an odometer back to inflate a car's value — is much harder to hide when the MOT history holds a public record of past readings. If the figures do not rise consistently, ask the seller to explain, and do not accept a vague answer.

What a gap in MOTs means

A missing year in the MOT record is worth understanding rather than fearing. It usually means one of a few things: the car was declared off the road with a SORN and genuinely not used, it was exported and later returned, or it simply went untested for a period. None of these is automatically sinister, but each changes the picture. A long gap followed by a test with heavy advisories can suggest a car that sat unused and deteriorated. Ask the seller to account for any missing years, and see whether their explanation fits the mileage pattern.

How MOT status differs from MOT history

These two terms are easy to confuse. MOT status tells you one thing only: whether the car has a valid MOT right now and when it expires. MOT history is the full record of every past test, with all the advisories, failures and mileage readings behind it. A car can have a perfectly valid current MOT while its history reveals repeated corrosion advisories or an implausible mileage jump. Always read the history, not just the expiry date — the status tells you the car is legal to drive today, while the history tells you how it got here.

The free gov.uk service is the right place to start, and for many buyers it answers the essential questions. If you want the MOT record sitting alongside finance, write-off, stolen and mileage checks in a single report, our MOT history check pulls it together so you are not cross-referencing separate sources by hand.

The bottom line

Reading an MOT history well is a skill worth having: look past the pass or fail and study the pattern of advisories, the steady climb of the mileage and any unexplained gaps. Do that before you view a car and you will walk in knowing exactly which questions to ask.
