Running an HPI check before buying is one of the most important habits a UK car flipper can build. Here is exactly what it checks, what to do when it flags something, and what it does not cover.
Of all the checks you should run before buying a car to flip, the HPI check is the one that protects you from a category of problem you cannot identify any other way. A car can look perfect, drive perfectly, and still be a legal and financial disaster waiting to happen.
Outstanding finance means the lender owns the car. A stolen marker means it can be recovered. A write-off status you did not know about means buyers will pay significantly less than you paid. An HPI check flags all of these in two minutes for £10 to £20.
HPI stands for Hire Purchase Information. The name comes from the original purpose of the check, which was to verify whether a vehicle had outstanding hire purchase finance registered against it. The term is now used generically to refer to any full vehicle history check, regardless of which provider runs it.
HPI is the original provider and the most widely recognised name. Other reputable providers include the AA Vehicle Check, the RAC Car History Check, and AutoTrader's history check. The underlying data sources are broadly similar across providers - all access the DVLA database, the finance register, the Insurance Write-Off Register, and the Police National Computer for stolen vehicles.
If a car has finance registered against it from a hire purchase or conditional sale agreement, the finance company retains legal title to the vehicle until the debt is fully paid. Buying a car with outstanding finance does not transfer that ownership to you - you are buying something the seller does not have the legal right to sell.
The lender can repossess the vehicle from you even though you paid the seller in good faith. Recovering your money from the seller is a separate civil matter - and often practically impossible if the seller has disappeared or has no assets.
The HPI check reveals whether the car has been declared a write-off by an insurer and, if so, which category. Category A and B vehicles should not be on the road. Category S and N vehicles can legally be repaired and resold but the status must be disclosed and it permanently suppresses value. Buying a Cat S or Cat N car without knowing it means you paid too much and will have difficulty selling at the price you expected.
If a vehicle is recorded as stolen on the Police National Computer, buying it and driving it constitutes possession of stolen property. The car can be seized by police at any point regardless of whether you knew it was stolen. The good faith buyer position offers some legal protection but the practical outcome - losing the car and being in a legal dispute - is serious.
The HPI check cross-references mileage recorded at MOT tests, at DVLA changes of keeper, and through other data points. A significant inconsistency - particularly a lower mileage at a later point than at an earlier point - is evidence of clocking. A car with artificially reduced mileage is worth substantially less than you are being asked to pay for it.
The check shows how many times the registered keeper has changed. This can be informative - a car that has had eight keepers in seven years has been passed around for a reason. It does not automatically indicate a problem but it is worth understanding before you buy.
An HPI check is not a mechanical assessment. It does not tell you whether the engine is in good condition, whether the gearbox is about to fail, or whether there are undisclosed faults. It covers legal and financial history only. You still need a physical inspection and a test drive.
It also does not guarantee the car is exactly as described in areas outside its database coverage. For full mechanical protection on higher value purchases, a pre-purchase inspection from the AA or RAC is a separate, worthwhile step.
Do not proceed until the finance is fully settled and you have written confirmation from the lender. The seller can contact their lender for a settlement figure and you can structure the payment to clear the finance directly. If the seller is reluctant to facilitate this, walk away.
Cat S or Cat N - decide whether you want a write-off flip based on the information above. Price your offer to reflect the permanent discount the marker applies and ensure you have full documentation of the repair. Cat A or Cat B - walk away immediately.
Do not buy the vehicle under any circumstances. If you are standing with the seller, you do not need to explain why you are leaving. Report the vehicle to the police if you are confident the stolen record is current.
The car has likely been clocked. Walk away, or negotiate a price that reflects what the actual mileage should be. Buying a clocked car and selling it without disclosing the discrepancy exposes you to misrepresentation claims.
Run the HPI check before you travel to view the car, not after. If the check flags a serious issue, you have avoided a wasted journey. If it comes back clean, you can view with confidence. The cost is £10 to £20. The cost of skipping it is potentially the full value of the car.
