MOT history check: what to look for before buying
An MOT history check helps you review a used car’s recorded tests before you travel to see it. Start with the free GOV.UK service, then compare the results with the advert and ask the seller about anything that needs explaining.

How to check MOT history for free
Use the free GOV.UK MOT history check to look up the car’s past tests. Have the registration number ready and confirm that the vehicle details match the car you are considering.
- Ask the seller for the registration if the advert does not show it.
- Open the official service and enter the registration.
- Check the latest result and expiry date, then read the earlier tests.
- Compare recorded mileages with the advert and note any faults to ask about.
For cars tested in England, Scotland and Wales, records are available from 2005 onwards. Northern Ireland results start in 2017. The service also lets you download certificates for tests in England, Scotland and Wales; it does not offer certificate downloads for Northern Ireland tests.
What to look for in the results
Work through the history in date order. A recent pass is useful, but earlier entries can help you decide which parts of the car need a closer look.
| Look at | What to compare | What to ask the seller |
|---|---|---|
| Latest result and expiry | Whether the record supports an advert claiming a recent MOT. | Was any work needed to obtain the pass, and is there an invoice? |
| Mileage readings | The sequence of readings, their units and the advertised mileage. | Can you explain an unexpected reading and provide supporting records? |
| Failures followed by a pass | The faults listed and the date of the later test. | What repairs were completed between the tests? |
| Recurring advisories | Whether the same component or concern appears more than once. | Has it been repaired or replaced, and what condition is it in now? |
Keep a short list of unresolved points. The record can tell you what was noted at a test; an invoice and a check of the car can help establish what happened afterwards.
Understanding failures and advisories
The current MOT result categories classify major or dangerous defects as failures. A pass may still include minor defects or advisories that need attention or monitoring.
A later pass needs context
A failure followed by a pass shows that the car met the test requirements at the later test. Ask for the repair invoice to see what work was carried out. The pass alone does not describe the repair or its cost.
Read repeated advisories carefully
Repeated notes about tyres, brakes, suspension or corrosion give you specific points to discuss. Ask what has changed since the last test and have any remaining concerns assessed. If a note disappears from a later record, do not assume that a part was replaced: ask for evidence.
Checking mileage and gaps between tests
Compare each reading with the ones before and after it, checking whether it is recorded in miles or kilometres. Then compare the latest reading with the advert, service paperwork and odometer at the viewing. A lower later reading needs an explanation, but it does not by itself establish deliberate mileage alteration.
Recording mistakes can happen. If the seller says an entry is wrong, ask them to follow the official process for correcting an MOT record and provide evidence. Check the updated record before relying on that explanation.
A gap between tests also needs context. Ask whether the car was off the road or outside the records covered by the service, and request documents that explain the period. A gap does not prove neglect, and the absence of a test does not confirm that the car was unused.
What if no MOT history appears?
Recheck the registration and vehicle details, then ask the seller for the latest certificate and an explanation. The car may not yet have needed a test, or older tests may fall outside the service’s coverage. If a test should be present, follow up the missing record rather than treating an empty result as a clean history.
An example: turning an advisory into a question
Suppose an advert says “fresh MOT”, but two earlier tests mention a worn suspension joint. The latest test passes without that note. This is an illustrative example, not a finding about a particular car.
A useful question to send the seller
“The earlier MOTs mention wear in a suspension joint. Was it replaced before the latest test? If so, could you send the invoice showing the date, mileage and work done?”
Compare any invoice with the car’s details. If the work cannot be confirmed, give the earlier test notes to an independent inspector and ask them to assess the suspension. Get a quote for any work they identify before deciding what to offer.
What an MOT history check cannot tell you
An MOT records specific checks at the time of the test. The GOV.UK explanation of the MOT test confirms that it excludes the condition of the engine, clutch and gearbox. It also does not establish the car’s current condition or confirm routine servicing.
Ask for the maintenance paperwork using our service-history checklist to see which jobs have been recorded. For finance, theft and insurance write-off records, read our car history check guide and check what each product includes.
Use the findings to prepare for a pre purchase car inspection and brief the inspector on your concerns. Bring your questions to the viewing and work through the used-car buying checklist before committing to buy.
How CarDiligence helps with your next checks
CarDiligence Snapshot brings the available MOT evidence together with the advert, price and previous-advert information. It helps you understand the findings and prepare questions for the seller. Snapshot does not include finance, write-off, stolen or service-history checks.
The Full Report adds wider history and service checks, buying guidance and estimated servicing and repair costs. Availability depends on the sources, and missing information stays unverified. Neither report includes a physical inspection or a warranty.
See the free sample report to decide whether the guidance would help with the car you have found. You can use the official MOT lookup for free without buying a report.
MOT history check FAQs
Is an MOT history check free?
Yes. The official GOV.UK MOT history service is free to use. CarDiligence is a separate paid report service that helps you interpret available records alongside the advert and prepare questions for the seller.
Can I check MOT history using just the registration?
Yes. You need the registration number for the official history lookup. For tests in England, Scotland and Wales, seeing the test location also requires the 11-digit number from the V5C log book. You do not need that number for the basic history check.
How far back does MOT history go?
The GOV.UK service provides car, motorcycle and van test results from 2005 onwards for England, Scotland and Wales, and from 2017 onwards for Northern Ireland. The available history depends on where and when the vehicle was tested.
Should I avoid a car with MOT advisories?
An advisory alone does not tell you whether to buy the car. Read the specific issue, ask what work has been done and check its current condition. Repeated notes about the same part deserve follow-up. Ask a garage or independent inspector to assess unresolved concerns and quote for any work needed.
Does a fresh MOT mean the car has been serviced?
No. An MOT pass does not prove that routine servicing is up to date. Ask for service invoices or digital records showing the dates, mileages and work completed, and compare them with the manufacturer’s recommendations for that car.
