HPI Checks Explained — What They Tell You and When You Need One

Outstanding finance, write-off history, stolen status — what a vehicle history check covers and why it matters.

A vehicle history check is not an optional extra when buying a used car privately — it is essential due diligence. The cost is typically between £5 and £25. The potential loss from buying a car with outstanding finance or a hidden write-off history can be thousands of pounds and loss of the vehicle entirely.

01.What a history check covers

A full HPI or equivalent check tells you whether the car has outstanding finance secured against it, whether it has been recorded as written off by an insurer (Category S, N, A, or B), whether it has been reported stolen, and whether the recorded mileage is consistent with its MOT history. It also confirms the DVLA's record of the make, model, and colour.

02.Outstanding finance — the biggest risk

If a seller has finance outstanding on a car and sells it to you, the finance company retains a legal interest in the vehicle. They can, in some circumstances, repossess the car even after you have paid for it. This is the most common costly problem found on history checks.

03.Write-off categories explained

Category A and B cars have been destroyed or salvaged and should never return to the road. Category S (structural damage) and Category N (non-structural) cars may have been repaired and returned to use — but you need to know. A repaired Cat S car may be safe, but it should be reflected in the price and disclosed by the seller.

04.How to run a check

You need the vehicle registration number. Use a reputable service — HPI, Carfax, Experian AutoCheck, or the DVSA's free MOT history checker at check.mot.gov.uk. The free MOT history check is a minimum — it covers mileage consistency and MOT advisories but not finance or write-off status.
