How to Check a Car's History in the UK
A used car's history is the single most important factor in any purchase decision. The UK has three main official data sources that together give a complete picture. Here is how to use them and what to look for.
The Three Official Data Sources
A complete UK car history check draws on three distinct databases:
- DVLA (Driver and Vehicle Licensing Agency)— holds registration data including keeper count, tax status, CO2 rating, first registration date, and V5C issue history.
- DVSA (Driver and Vehicle Standards Agency)— holds the full MOT test history including pass/fail status, mileage at each test, and advisory items going back to 2005.
- Experian AutoCheck — holds finance data (outstanding agreements registered with lenders), insurance write-off categories (Cat A, B, S, N), police-recorded theft markers, previous registration plates, and VIC (Vehicle Identity Check) markers.
DVLA and DVSA data is accessible for free. Experian data requires a paid query — this is the data that matters most when buying a used car.
Step-by-Step: Running a Check
- Enter the vehicle's registration number at vehixa.co.uk
- The free check returns MOT history, tax status, keeper count, and basic vehicle details
- For a full check, purchase a report to add finance, theft, and write-off data
- Review the results against what the seller has told you
- If any red flags appear, investigate further before committing to a purchase
What to Look For in MOT History
MOT history is free and provides crucial data points beyond just pass or fail:
- Mileage progression — check that mileage increases consistently over time. Any decrease or suspiciously flat period is a strong indicator of odometer clocking.
- Recurring advisories — if the same items appear as advisories year after year, they have not been addressed.
- MOT gaps — a gap in the MOT record (especially on an older car) suggests a period off the road. Ask why.
- Failure items — MOT failures reveal what was wrong with the car. Check whether repairs were made or the car was simply retested at a different station.
Critical Red Flags
These findings in a history check should cause you to reconsider or negotiate significantly:
- Outstanding finance — the finance company can legally repossess the car
- Cat A or Cat B write-off — should never legally be on the road again
- Active theft marker — the car could be seized by police
- Mileage discrepancy in MOT records — strong evidence of clocking
- Previous identity as a different vehicle — suggests plate cloning
Frequently Asked Questions
What is the best way to check a car's history in the UK?
The most comprehensive approach is to use a service like VEHIXA that combines DVLA data (tax, keeper count), DVSA data (MOT history, mileage), and Experian AutoCheck data (finance, stolen, write-off). Together these cover the main risks of buying a used car.
Can I check a car's history for free?
Partially. MOT history is available free via the DVSA's official check tool, and tax/SORN status is free via the DVLA enquiry. However, finance checks, theft markers, and write-off data require a paid report from services like VEHIXA.
What does a full car history check include?
A full check covers: DVLA data (keeper count, tax status, first registration date), DVSA data (full MOT history with mileage), Experian AutoCheck data (outstanding finance, stolen markers, insurance write-off categories, previous number plates, VIC markers), and optionally a valuation.
How far back does UK MOT history go?
The DVSA holds MOT records going back to 2005 for most vehicles, with some records earlier than that. Each record includes the test date, result (pass or fail), mileage, and any advisory or failure items. This mileage data is invaluable for spotting odometer clocking.
What are the biggest red flags in a car's history?
The most serious red flags are: outstanding finance (someone else legally owns it), Cat A or Cat B write-off (structurally unsafe, should never be on the road), active theft marker, significant mileage discrepancy between MOT records, and a large gap in MOT history that cannot be explained.
