A vehicle history check (commonly called an 'HPI check' after the market-leading provider) typically costs £10-£20 and checks a car's registration against national databases for outstanding finance, write-off/insurance-total-loss history, stolen markers, mileage discrepancies, and import/plate-change history. It cannot tell you about mechanical condition — that still requires a physical inspection or independent engineer's check.
At a glance
| Check item | What it flags |
|---|---|
| Outstanding finance | Whether the car is security against an unpaid loan |
| Write-off/insurance history | Whether the car has been declared a total loss, and its category |
| Stolen marker | Whether the vehicle is registered as stolen and not recovered |
| Mileage check | Discrepancies against previously recorded mileages ('clocking') |
| Plate changes/import status | Number plate change history and whether the car was imported |
Why a history check matters
Buying a used car with hidden outstanding finance means the finance company can, in some circumstances, repossess the car from you even though you bought it in good faith and paid in full — the debt sits against the vehicle, not just the previous owner. A history check for £10-£20 is cheap insurance against a mistake that could cost thousands, which is why it's considered a standard step for any private used car purchase in the UK.
What the check actually covers
- Outstanding finance: cross-references the registration against finance industry databases.
- Write-off status: flags whether an insurer has ever declared the car a total loss, and which category (Cat A, B, S or N) applied.
- Stolen marker: checks police records for vehicles reported stolen and not recovered.
- Mileage discrepancy: compares mileage recorded at MOT tests and other data points against the current odometer reading, flagging inconsistencies suggestive of clocking.
- Plate and identity history: shows number plate changes and, where relevant, import history and whether the VIN/registration combination is consistent.
What it doesn't tell you
A history check is a records check, not a physical inspection — it won't tell you about engine condition, hidden accident damage that was never claimed on insurance, or upcoming maintenance needs. Pair it with a proper test drive, a look underneath and around the car for damage or corrosion, and ideally an independent inspection for higher-value purchases.
How to run one, and what to do with the results
- Get the check from a reputable provider — HPI, RAC, AA and others offer essentially the same underlying data with slightly different presentation and price.
- Cross-check the VIN on the physical car against the VIN on the report and the V5C logbook — they should all match exactly.
- If outstanding finance is flagged, ask the seller to settle it before purchase, or walk away — never just take a verbal assurance it'll be 'sorted after the sale'.
- If a write-off category is flagged, ask for the repair paperwork and consider an independent engineer's inspection before proceeding, particularly for structural (Cat S) repairs.
Some free 'history check' websites only provide a partial picture (tax/MOT status from gov.uk, which is already free) rather than the finance, write-off and stolen-marker data that makes a paid check worthwhile — check exactly what's included before paying.
