HPI is the best-known brand name in UK vehicle history checks. Most people who say "run an HPI check" mean any paid vehicle history search, in the same way people say "Hoover" when they mean any vacuum cleaner.
The HPI brand charges £19.99. Bad Drivers UK charges £9.99 for a check using the same Experian-sourced data.
Here is what an HPI check actually covers, what the results mean, and why the price difference exists.
What Is an HPI Check?
HPI originally stood for Hire Purchase Information. The register was set up to let lenders and buyers check whether a car had outstanding hire purchase finance on it. Over time the service expanded to cover stolen markers, write-offs, keeper history, and more.
The HPI brand is now owned by Solera, a US data company. When you run an HPI check through their website, you are paying Solera to query Experian's vehicle data platform on your behalf and return the results in their branded format.
What Does an HPI Check Show?
A full vehicle history check, regardless of provider, should cover these data sources:
Finance register. Searches Experian's register of UK vehicles with outstanding finance agreements. If a car has finance, the lender's claim is secured against the vehicle itself. You could buy the car and still lose it.
Stolen vehicle register. Cross-references the Police National Computer and insurance industry stolen databases. A stolen car cannot legally be sold, and buying one in good faith does not protect your ownership.
Write-off register. Shows whether the car has ever been declared a total loss by an insurer. Categories are: Cat A (crush only), Cat B (body shell to be crushed), Cat S (structural damage, can be repaired and returned to road), Cat N (non-structural damage, can be returned to road). A Cat S or Cat N write-off is not automatically a problem, but it must be declared and priced accordingly.
Keeper history. How many registered keepers the vehicle has had, and the dates of keeper changes. More keepers than expected for the age and mileage can indicate problems.
Plate changes. Whether the registration has been changed. Changed plates can be used to disguise a stolen vehicle or hide a poor history from a previous registration.
Mileage data. Cross-references mileage figures from MOT tests, finance applications, and other sources to flag potential odometer tampering.
MOT history. Full DVSA MOT records showing pass and fail dates, mileages at each test, failure reasons, and advisories.
DVLA registration data. Confirms make, model, colour, engine size, and year against the DVLA record. Useful for confirming the car in front of you matches what is on the V5C.
How Much Does an HPI Check Cost?
The HPI brand charges £19.99 for a standard check. This gives you a single report covering the data sources listed above.
Bad Drivers UK charges £9.99 for a full vehicle history check. The check uses the same Experian data sources and covers the same registers.
The price difference is not a difference in data quality. It is a difference in overhead, branding, and marketing spend. The underlying data is sourced from the same place.
The Experian Connection
Experian is the data provider behind most UK vehicle history checks, including HPI. Experian maintains the finance register, processes the insurance write-off data, and manages the central vehicle data platform that third-party check providers query.
When you pay for an HPI check through the HPI brand, you are paying for access to Experian's data. When you run a check through Bad Drivers UK, you are also accessing Experian's data. The output is branded differently and the price is different. The source data is the same.
This is not unique to vehicle checks. Most financial data products in the UK work this way. Several providers sell access to the same underlying bureau data at different price points.
What to Do With the Results
A clean result means no finance, stolen marker, write-off, or suspicious mileage entries were found. That is a positive sign, not a guarantee. Very small informal finance arrangements may not appear on the register. But a clean result from a reputable provider significantly reduces your risk.
If the check shows outstanding finance, walk away unless the seller can demonstrate in writing that the finance has been settled before you hand over money.
If the check shows a stolen marker, do not buy the car and report it to the police.
If the check shows a Cat S or Cat N write-off, factor that into your price negotiation and get an independent mechanical inspection before proceeding.
If there is a plate change, ask the seller for an explanation and check the V5C for consistency.
Is an HPI Check Worth It?
Yes. The only question is which provider to use.
You should run a full vehicle history check before any used car purchase, without exception. The check tells you things the seller may not know and things some sellers are actively hiding. A car with outstanding finance can be repossessed by the lender even after you buy it.
Spending £9.99 before handing over thousands is not optional.
