An MOT expiry date tells you when the next test is due. The history shows what happened at earlier tests: recurring corrosion, suspension wear, failed items and mileage readings worth questioning. Review both before deciding whether a car deserves a viewing.
Start with the free GOV.UK check
You can access the records yourself, free of charge:
- Visit the official GOV.UK MOT history service and start the check.
- Enter the registration number, then confirm that the returned vehicle details match the car you are considering.
- Review the expiry date and previous tests, including results, recorded mileage, defects and advisories.
Anyone can make a basic check, including a prospective buyer. The registration number is enough; viewing test locations requires the 11-digit reference from the V5C log book.
Used cars on finance need the same scrutiny as cars bought outright: review the test history before agreeing to buy, while there is still time to ask the seller about anything unusual.
Turn failures and advisories into questions
Work through the entries in date order, looking for recurring issues as well as individual failures.
Major and dangerous defects cause an MOT failure. A car can pass with minor defects, which still need attention. Advisories are a separate category of observations about matters to monitor or address.
Treat a previous failure as a starting point for questions, rather than an automatic reason to reject the car. Ask what happened afterwards and request supporting paperwork.
If corrosion or suspension wear appears across several tests, establish which component was affected, what action was taken and whether further work has been recommended. Look for invoices identifying the vehicle, date and work completed, rather than a general assurance that everything was sorted.
An advisory disappearing from a later result is a reason to ask what changed. On its own, that absence provides no documentary evidence of a particular repair.
A worked example: advisory, failure and retest
In this hypothetical history, one annual test records an advisory for wear in a front suspension bush. At the next test, deterioration in that bush results in a failure. A few days later, the car passes a retest.
Ask whether the bush was replaced or a larger suspension assembly was fitted. The invoice should identify the parts fitted and work carried out; compare its date and component description with the test entries.
If the seller struggles to explain the sequence, flag that area for an independent inspector to examine.
Clarify unusual mileage and missing records
Compare successive mileage readings with the advertised mileage and, at the viewing, the dashboard. Check the units as well as the figures.
A lower reading at a later test warrants investigation, not an immediate accusation of clocking. A recording error or documented instrument replacement could explain it. Ask for service invoices carrying mileage readings or paperwork for a replacement instrument cluster, and check whether those documents support the explanation.
Missing records also need context. The official service holds car test results from 2005 in England, Scotland and Wales, and from 2017 in Northern Ireland. Earlier tests therefore fall outside those online records.
If an expected test is absent, recheck the registration and available date range first. Then ask the seller for relevant certificates or an explanation of the gap. Establish the reason before assuming that an empty year means the car was used illegally.
Put the MOT record alongside other evidence
MOT history and service history answer different questions. For oil changes, timing-belt replacements and other scheduled maintenance, look for separate service records and invoices. Check that they relate to the same vehicle and show when the work took place.
Outstanding finance, theft and insurance write-offs also require separate vehicle-history checks. Keep those enquiries distinct from the MOT lookup.
A historical pass records compliance with the tested standards at that point, not a guarantee of the car’s condition today. Take a short list of unresolved entries to the viewing and ask the seller to explain them alongside the paperwork. Where defects recur, mileage remains unclear or documents conflict with the explanation, consider an independent inspection before committing.
