What Does a Bad MOT History Look Like?

A “bad” MOT history is not a fixed number of failures or advisories. Read the pattern over time, then compare it with the car, its age, mileage, paperwork and seller.

What MOT history can tell you

GOV.UK’s MOT history service can show pass/fail results, recorded mileage and relevant defects or minor problems. It can help you identify themes and prepare questions before viewing.

What it cannot tell you

It is not a complete repair record or current-condition report. It does not prove why a problem occurred, whether a repair was high quality or whether an item has since deteriorated.

Is a failure automatically a bad sign?

No. Read what failed, when it happened, what occurred at a retest and whether the seller can support the story with relevant documents.

Repeated issues and patterns

Similar tyre, brake, suspension or corrosion entries over several tests can justify further investigation. Compare dates and mileage rather than treating every repeat as the same situation.

Mileage and gaps

Compare recorded mileage with service paperwork and the dashboard. Ask about long gaps too; a period of non-use can have ordinary explanations, but the evidence should make sense.

A clean recent MOT

A recent pass is useful information but does not establish perfect condition or remove the need to understand previous concerns.

Frequently asked questions

Are three MOT failures too many?

There is no responsible universal threshold. What failed, when, how it was resolved and current condition matter more than a count.

Does MOT history show every repair?

No. It records test outcomes and observations, not a complete maintenance history.
