What is an HPI check — and do you need one?
5 min read · Updated 1 July 2026
'HPI check' is a brand name that became a generic term, like Hoover or Sellotape. Here's what's actually inside one, and where the same data comes from for less.
The short version
An HPI check is a vehicle history report keyed on the registration number. It reveals things you can't see from a walkaround: outstanding finance, insurance write-off history, stolen status, mileage discrepancies, plate and colour changes, previous keepers, and import/export records.
Where the data comes from
- Finance — from the Finance & Leasing Association and major lenders.
- Write-offs — from MIAFTR, the insurance industry's total-loss register.
- Stolen — from the Police National Computer.
- Mileage — from DVSA MOT records and the National Mileage Register.
- V5C, keepers, tax — from DVLA.
The point: every reputable provider — HPI, RAC, AA, us — pulls from the same wholesale feeds. The check is the check. Price differences are marketing, not data.
Do you need one?
For a private-sale purchase over about £1,000 — yes, always. Buying without a check leaves you exposed to two catastrophic outcomes:
- Finance repossession — the lender takes the car back and you lose the money.
- Undisclosed write-off — the car is worth a fraction of what you paid, and can be dangerous.
What's in a good report
Look for these categories at minimum: DVLA record, MOT and mileage history, outstanding finance, insurance write-off (all categories — S, N, C, D), stolen status, previous keepers, plate history, and market valuation. Our Full Buyer Protection Check covers all of these.
What a check doesn't tell you
History checks are documentary — they don't inspect the car. They won't flag a bodged repair that wasn't logged with an insurer, or an engine on its last legs. Combine the check with a physical inspection or an AA/RAC pre-purchase inspection for high-value buys.
