A vehicle’s MOT history is one of the most powerful tools available to buyers, dealers, and traders when assessing risk. Beyond simple pass or fail results, MOT records can reveal patterns of neglect, predict future repair costs, and highlight potential safety concerns.
In this guide, we answer two key questions — and a few closely related ones — to help you interpret MOT history with confidence.

Should I worry about repeated MOT advisories?
Yes — repeated MOT advisories are often a red flag and should never be ignored.
An MOT advisory is issued when a component is worn, deteriorating, or approaching the point where it could soon fail. While a single advisory isn’t usually a cause for concern, the same advisory appearing year after year can indicate a deeper issue.
Why repeated MOT advisories matter
When advisories are repeated across multiple tests, it may suggest:
- Deferred maintenance – Repairs are being postponed until parts fail completely.
- Increased ownership risk – The vehicle may require significant work shortly after purchase.
- Safety concerns – Worn brakes, tyres, suspension, or steering components can deteriorate rapidly.
- Poor servicing habits – A lack of preventative maintenance often affects multiple systems.
Repeated advisories show a pattern — and patterns are far more important than individual MOT results.

Advisories that deserve extra attention
Some advisories are particularly important when they appear more than once:
- Tyres close to or below the legal tread limit
- Brake pads or discs worn or deteriorating
- Suspension components with play, wear, or corrosion
- Exhaust corrosion or leaks
- Oil leaks noted at consecutive tests
If these advisories continue without improvement, the vehicle may be maintained only to the bare minimum standard.
Are repeated advisories always a deal-breaker?
Not necessarily. Some advisories are common and relatively low risk, especially on older vehicles:
- Minor surface corrosion that hasn’t worsened
- Light oil misting with no active leaks
- Non-structural exhaust corrosion
The key is trend and severity. A single advisory that disappears the following year suggests repairs were carried out. Repeated advisories with no change suggest neglect.
How long does MOT history stay on record?
MOT history is stored on the DVSA database and remains accessible for the lifetime of the vehicle, as long as records exist.
In practice, you can usually view:
- All MOT tests from the vehicle’s first MOT (typically at three years old)
- Passes, failures, and advisories for each test
- Mileage readings recorded at each MOT
There is no automatic expiry date for MOT history. Older records may become less relevant over time, but they are still valuable for spotting long-term trends.

Related MOT history questions buyers often ask
Should I be concerned if advisories disappear suddenly?
Sometimes. Advisories disappearing can mean repairs were carried out — but they can also indicate:
- A change of MOT testing station
- Inconsistent inspection standards
- Items being overlooked rather than repaired
Comparing mileage, test timing, and advisory patterns helps clarify what’s really happening.
Is a clean MOT history always a good sign?
Not always. A vehicle with no advisories at all over many years can raise questions, especially on higher-mileage cars. Genuine wear is normal — a completely spotless history may warrant closer inspection.
How far back should I check MOT history?
Ideally, review at least the last 5–6 MOTs. This gives a clear picture of how the vehicle has been maintained and whether issues are improving, worsening, or being ignored.
Why MOT history matters when assessing vehicle risk
MOT records aren’t just about legality — they help predict:
- Future repair and servicing costs
- Safety risks
- Long-term reliability
- Ownership habits of previous keepers
When combined with finance, write-off, mileage, and theft checks, MOT history becomes a vital part of making an informed decision.
Additional MOT history questions
Do MOT advisories affect a car’s value?
Yes. Repeated or serious advisories can reduce a vehicle’s resale value, especially if they relate to safety-critical components such as brakes, suspension, tyres, or structural corrosion. Buyers often factor expected repair costs into their offer, and dealers may price vehicles more conservatively when advisory patterns suggest future work.
Can a car pass its MOT and still have serious issues?
Yes. An MOT is a minimum roadworthiness test, not a full mechanical inspection. A vehicle can legally pass while still having worn components, underlying faults, or advisories that may soon turn into failures. This is why reviewing advisories — not just pass results — is essential.
Are MOT advisories legally required to be fixed?
No. Advisories are not a legal requirement to repair. However, ignoring them can lead to:
- MOT failures at future tests
- Increased safety risks
- Higher repair costs if issues worsen
Responsible owners usually address advisories before they escalate.
Can MOT history show signs of clocking or mileage issues?
Yes. MOT mileage readings recorded each year can help identify inconsistencies, sudden drops, or unusual gaps that may indicate mileage discrepancies. When combined with other mileage data, MOT history becomes a key tool for detecting potential odometer fraud.
Do different MOT testing stations give different advisories?
They can. While MOT standards are regulated, advisory wording and interpretation can vary slightly between testing stations. However, consistent advisories across different garages often strengthen the case that an issue is genuine and unresolved.
Is corrosion on an MOT advisory always serious?
Not always. Surface corrosion is common, particularly on older vehicles. However, advisories mentioning structural corrosion, excessive deterioration, or corrosion close to mounting points should be treated seriously, as they can lead to costly repairs or future failures.
Should dealers disclose MOT advisories to buyers?
Yes. Transparency around MOT history helps build trust and reduces the risk of disputes. Providing context — such as repairs completed after advisories — can reassure buyers and support a smoother sale.
Key takeaway:
Don’t just check whether a vehicle passed its MOT — look for patterns across advisories, mileage, and failures. MOT history tells a long-term story about maintenance, risk, and ownership habits, and that story often matters more than a single pass certificate.
