Full Vehicle Health Report
Overall verdict, defect breakdown, mileage credibility — all from official DVSA records. Free for any UK vehicle, results in seconds.
What's included
Everything in one free health check
Based on the complete DVSA record — every MOT test ever recorded for the vehicle, going back to 2005.
Overall Verdict
A scored verdict of Positive History, Proceed with Caution, or Needs Investigation — calculated from the complete record, not just the most recent test.
Pass Rate Analysis
The first-time pass rate across every recorded MOT. A vehicle that repeatedly fails before passing has a very different risk profile to one with a clean streak.
Defect Breakdown
All defects and advisories grouped by system — brakes, suspension, corrosion, steering, tyres — with severity labels and plain-English explanations of what each means.
Mileage Credibility
Every recorded odometer reading plotted over time. Any drop in mileage, suspicious jump, or implausible annual average is flagged as a clocking risk.
Safety Red Flags
Dangerous defects, recurring structural failures, SORN history, and mileage anomalies all surface clearly — not buried in pages of test data.

Understanding your result
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 — dangerous defects and mileage inconsistencies — 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.

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.
Why it matters
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 DVSA 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.
~150,000
Clocked cars sold annually
An estimated 150,000 vehicles with wound-back odometers are sold in the UK every year — often at inflated prices.
68–70%
UK national pass rate
The UK average first-time pass rate is 68–70%. A vehicle consistently below this 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."
