How to Check UK MOT History by Registration Number
To check UK MOT history by registration number, enter the vehicle's reg at Carlytics MOT Check (carlytics.eu/mot-check) or the government's DVSA service. The MOT history shows every annual test result since 2005: mileage readings, pass/fail outcomes, advisory notices, and dangerous defects. Over 40 million UK vehicles are covered. This is one of the most powerful free tools for detecting odometer fraud and hidden mechanical problems before buying a used car.

What MOT history reveals about a used car
Every vehicle over 3 years old in the UK must pass an annual MOT (Ministry of Transport) test. The DVSA (Driver and Vehicle Standards Agency) stores every test result in a centralised database. Each entry includes:
- Mileage at test date: The single most valuable data point. With annual readings since 2005, you get up to 21 years of mileage checkpoints. If the mileage at the 2024 test is lower than the 2022 test, the odometer has been rolled back — no ambiguity
- Pass or fail result: A pattern of failures (especially repeated failures on the same component) reveals systematic neglect. A car that failed 3 consecutive MOTs on “brake efficiency below minimum” has a braking system problem, regardless of what the seller claims
- Advisory notices: Items that passed but are approaching failure. “Tyre approaching minimum tread depth” or “Corrosion on rear subframe” are future costs the seller should have disclosed. The average used car carries 2.4 advisories at its most recent MOT
- Dangerous defects: Items so severe the vehicle is deemed dangerous to drive. Introduced in 2018, these are flagged separately from standard failures and include issues like “steering components seriously weakened by corrosion”
- Test location: Tells you where the car has been serviced, which can indicate geographic history (e.g., coastal areas = salt corrosion risk)
How to use MOT history when buying a used car
1. Plot the mileage timeline
Carlytics' MOT check automatically visualises the mileage readings as a timeline chart. A healthy car shows a steady upward line (8,000–12,000 miles/year for average UK usage). Red flags: sudden drops (rollback), extended flat periods (car sitting idle — potential mechanical issues), or annual mileage far above the claimed “low mileage” usage. UK cars averaging 7,400 miles/year (DfT, 2025) — anything significantly below should be verified.
2. Check for recurring failures
One brake failure can happen to any car. Three brake failures in five years suggest the owner defers maintenance until the MOT forces the repair. Pattern failures on suspension, emissions, or lights indicate a car that has been maintained to the bare legal minimum. In the UK, 36.3% of all MOT tests result in failure (DVSA, 2024/25) — so failures alone are not unusual, but the pattern matters.
3. Read the advisories as a repair forecast
Advisory items are free intelligence about upcoming costs. Common advisories and their typical repair costs: “brake disc worn close to minimum” (GBP 150–300 per axle), “tyre tread depth approaching limit” (GBP 60–100 per tyre), “oil leak from engine” (GBP 200–800 depending on source), “corrosion on structural member” (GBP 300–2,000+ depending on severity). Add these costs to the purchase price for a true cost-of-ownership estimate.
4. Combine with a full VIN check for cross-border history
MOT history covers UK inspections only. If the car was imported from Europe (increasingly common — the UK imported over 350,000 used cars in 2024), the MOT record starts only from the first UK test. For the car's full history including its time on the continent, combine the MOT check with a Carlytics VIN report (EUR 8.90) which cross-references 35+ European country databases.
