Score breakdown
What the health score means
Every vehicle gets a score from 0 to 100. The score reflects the overall risk profile — not just whether the latest MOT was passed.
Strong first-time pass rate, no dangerous defects, consistent mileage. A well-maintained vehicle with a clean record — a good starting point for any used car purchase.
Lower pass rates, one or more major defects, or mileage irregularities in the record. Not necessarily a dealbreaker — but warrants further investigation before committing.
Dangerous defects, repeated MOT failures, structural issues, or confirmed mileage anomalies. An independent physical inspection by a qualified mechanic is strongly recommended before purchase.
Scoring factors
What goes into the score
The score combines multiple dimensions of the vehicle's history. Safety-critical outcomes carry more weight than minor advisories.
We look at test history — how consistently the vehicle has passed, and whether failures are isolated or recurring. Vehicles with repeated pre-test failures tell a different story to those with a clean first-time pass streak.
Defect severity matters too. A handful of minor advisories is normal wear. Dangerous defects, corrosion failures, or structural issues are weighted heavily — they indicate real risk, not just age.
Mileage credibility is checked against every recorded odometer reading. Any drop in mileage between tests is a definitive red flag. Implausible annual additions are flagged as inconsistencies.
Finally, current status — MOT validity, SORN history, and how recently the vehicle was last tested — rounds out the picture.
How it works
Free, instant, and pulled directly from official DVLA records — no account or sign-up required.
Type in a number plate — any UK vehicle with MOT records from 2005 onwards is supported. No account or sign-up required.
Every MOT test result, defect, advisory note and odometer reading is pulled directly from the official government database in real time.
Our algorithm scores pass rates, defect severity, mileage consistency and safety flags — then gives you a plain-English verdict and full breakdown you can act on.
A used car's MOT history tells you what the seller can't
A single MOT pass tells you a car met the minimum legal standard on one specific day. It says nothing about how often it failed in the past, what defects have been recorded over the years, or whether the same problems keep coming back. Our MOT Health Check analyses the complete history — every test, every defect, every recorded odometer reading — and produces a clear verdict.
A vehicle with a strong recent MOT but a history of dangerous defects, corrosion failures, or a low first-time pass rate is a very different risk to one with a clean, consistent record. The health check surfaces that difference immediately, without requiring you to interpret years of raw government data yourself.
The mileage credibility check is equally important. Clocking — fraudulently winding back the odometer — affects an estimated 150,000 vehicles sold in the UK every year. Because DVLA records the odometer at every test, any decrease in mileage between tests is unambiguous evidence of tampering. We also flag implausible annual increases that suggest the record has gaps.
Estimated UK vehicles with wound-back odometers sold each year — often at inflated prices.
A vehicle consistently below this average is a red flag worth understanding before buying.
"The health check is an essential first step — not a substitute for a physical inspection, but the fastest way to know whether a vehicle's history is worth trusting."
