What Does an HPI Check Show?

What an HPI-style provenance check actually shows

A provenance check pulls together records from several sources — finance houses, insurers, the police national stolen register and the DVLA — to build a picture of a vehicle's documented past. The aim is to surface the things a dishonest or simply uninformed seller might not mention. These are the checks that protect you legally and financially, not mechanically.

The headline items most people buy a provenance check for are outstanding finance and write-off history, because both can cost you the car or thousands of pounds after you have already paid. The other records help you confirm the car is what the seller claims it is.

A typical provenance check covers the following:

• Outstanding finance: whether money is still owed on the car under a hire purchase or PCP agreement. If there is, the finance company can legally repossess the car even after you buy it.
• Insurance write-off and salvage records: whether an insurer has ever declared the car a total loss, and the category (Cat A, B, S or N) that tells you how serious the damage was.
• Stolen status: whether the vehicle is currently recorded as stolen on the Police National Computer.
• Mileage records: readings logged at MOTs and other points, flagged where they fall rather than rise, which can indicate clocking.
• Number plate (VRM) changes: previous registrations, which can sometimes be used to obscure a car's past.
• Registered keeper changes: how many keepers the car has had and when ownership changed, which provides context for the rest of the history.
• Vehicle identity: make, model, colour, engine size and other DVLA-held details so you can confirm the V5C logbook matches the actual car.

Why finance and write-off checks matter most

Of everything a provenance check shows, outstanding finance is the one that can hurt you most directly. In the UK, if a car is still on a finance agreement when you buy it, the finance company — not the seller — legally owns it. They can repossess the car from you, and you are left chasing the seller for your money. A finance check is the single best reason to run a provenance check before handing over cash.

Write-off history is the other big one. When an insurer pays out a total loss, the car is given a salvage category. Cat A and Cat B vehicles should never return to the road. Cat S means structural damage was repaired; Cat N means non-structural damage was repaired. A Cat S or Cat N car can be perfectly safe and legal to drive, but it is worth significantly less than a clean equivalent, and you have every right to know before you pay full price.

A provenance check tells you that a write-off was recorded and its category. It does not tell you how well the repair was carried out — that is a job for a physical inspection, which we cover below.

Mileage flags matter too. A car advertised with low mileage that has an MOT reading higher than its current odometer is a red flag for clocking, and clocked cars are both unsafe to value and potentially being sold dishonestly.

What an HPI check does NOT show

This is the part most guides skip, and it is exactly where buyers get caught out. A provenance check is a records check. If something was never reported to an insurer, the police or the DVLA, it will not appear — and the absence of a record is never proof that a car is clean or safe.

A check cannot tell you the mechanical or cosmetic condition of the car in front of you. It will not reveal worn brakes, a tired clutch, a slipping gearbox, oil leaks, electrical faults or the state of the tyres. None of that is in any database.

It also cannot judge repair quality. A car may carry a Cat N record, but only an inspection will tell you whether the repair was done to a high standard or bodged. Equally, a car with no write-off record may still have been crash-damaged and repaired privately, without any insurer ever being involved — so no record exists.

Treat a clean provenance report as a green light to proceed with viewing and inspecting, not as a guarantee. The records confirm the car is legally safe to buy; your eyes, a test drive and ideally an independent inspection confirm it is mechanically worth buying.

• Mechanical condition — engine, gearbox, clutch, brakes, suspension, tyres.
• Repair quality — whether recorded or unrecorded damage was fixed properly.
• Unrecorded damage — accidents repaired privately with no insurance claim.
• Service history gaps — whether the car was actually maintained on schedule.
• Hidden cosmetic issues — fresh paint or filler covering past damage.

What you can check for FREE before paying for anything

You do not need to pay for a provenance check to start. Several of the most useful records are public, and you can confirm them in minutes from the registration number alone. This is where we recommend every buyer begins — it is honest, it is free, and it often surfaces a problem before you spend a penny on a paid report.

From the reg, you can pull the car's full MOT history, including every recorded mileage reading, advisories and failure items. Comparing those mileage readings over time is one of the most reliable free ways to spot clocking, because a genuine odometer only ever goes up. You can also check the car's tax status, and confirm that the make, model, colour and engine details match the V5C logbook and the car in front of you.

These free checks — MOT history, mileage trail, tax status and DVLA vehicle details — are exactly what MOT Checkup provides at no cost. They tell you a lot about whether a car has been looked after and whether its mileage story holds up.

What free public data does not include is licensed finance and stolen records, or a consolidated write-off marker. Those come from finance houses, insurers and the police register, which are only available through a paid provenance check. Be wary of any free tool that implies it can confirm a car is finance-free or has never been stolen — that data is not free.

When a paid provenance check is worth it

A free check is the right first step, but it is not the whole job. Once a car passes your free checks and you are seriously considering buying it, a paid provenance check is worth the small cost — especially for any car bought privately, any car at the higher end of your budget, and any car where the price looks suspiciously good.

The two things you are really paying for are the licensed finance check and the consolidated write-off and stolen markers. On a car costing several thousand pounds, paying for that peace of mind is sensible insurance against a very expensive mistake.

Be realistic about what you are getting, though. A paid report confirms the records; it still does not inspect the car. The strongest position for any private buyer is the combination of free public checks, a paid provenance check, and a physical inspection or independent mechanic's report before money changes hands.

Start with the free checks. Run the MOT history, mileage trail, tax status and vehicle details on MOT Checkup using just the registration, and see whether the car's story holds up before you pay for anything. When you are ready to add licensed finance, write-off and stolen data on top, our HPI check alternative page explains your options and how an honest provenance check fits alongside the free data you have already gathered.
