HPI Check: Know a Used Car's Hidden History Before You Pay
Before you hand over a deposit on a used car, an HPI check tells you within minutes whether it is hiding outstanding finance, a write-off past, a stolen record or a clocked odometer. Around one in three used vehicles carries hidden history or unsettled finance (Solera cap hpi, 2024).
Enter a UK or NI registration plate in the tool on the right to run the history check, then use the same tool to estimate the VRT due if you bring the car home — no signup, no email required.

The basics
What Is an HPI Check (and What Does HPI Actually Mean)?
HPI stands for Hire Purchase Investigation — originally a simple check to see whether a car was still tied to a finance agreement, now the generic name for any full vehicle history check. When someone says "run an HPI check", they mean scanning a car's background for finance, write-off, theft and mileage red flags before purchase.
At a glance
- An HPI check queries finance, write-off, stolen and mileage records against a car's registration and VIN.
- Outstanding finance is the biggest legal risk: the lender can repossess a car you paid for in good faith.
- Cat A and Cat B cars must be scrapped; Cat S and Cat N can legally return to the road after repair.
- For a UK/NI import, check the history first, then estimate the registration cost (VRT) before you commit.
From "Hire Purchase Investigation" to a Generic Term
The phrase dates back to when finance houses needed a fast way to confirm a used car was not still under a hire purchase agreement. Over decades the "HPI check" name stuck and broadened, so today it is shorthand for a complete car history report rather than any single product. That is why buyers across Ireland use the term even when no company of that name is involved.
What an HPI Check Means in the Irish Context
In Ireland there is no local company called "HPI"; it is a generic label for a history check that draws on Irish finance records and the vehicle's own data. A check here queries the Central HPI Finance Database — the shared record of hire purchase and finance agreements held by Irish lenders — alongside write-off and mileage records, matched to the car's VRM (registration mark) and VIN.
Why this matters: that combination of finance database, VRM and VIN is what makes the result specific to the car in front of you — not a generic estimate for the model.
The report
What Shows Up on an HPI Check in Ireland?
An HPI check in Ireland surfaces six major risks: outstanding finance, write-off status, theft, tampered mileage, previous owners and the car's import/export history. With 29.2 million HPI Checks run in 2024 (Solera cap hpi), the format is the recognised standard for spotting these problems before money changes hands.
Outstanding Finance: The Risk of Liability and Repossession
Outstanding finance is the single most dangerous find. If a previous owner took the car on hire purchase and never cleared the debt, the lender — not the seller — remains the legal owner. You can pay in full, in good faith, and still have the car repossessed, checked against the Central HPI Finance Database. This is a financial and legal trap no visual inspection can catch.
Write-off, Theft and Clocked Mileage
Three classic red flags sit close together in any report. An insurance write-off means the car was once declared a total loss; a stolen marker (recorded with An Garda Síochána in an Irish context) means it should never be sold on; and a mileage discrepancy points to clocking.
-
Write-off.
Flagged with its category (see the table below).
-
Stolen.
A live theft marker should end the deal immediately.
-
Clocked mileage.
Spotted when two successive readings fall out of sequence — a 92,000 km reading followed by a later 68,000 km entry is a textbook clocking flag.
Previous Owners, VIN, Import/Export and Safety Recalls
The report also builds a picture of the car's ownership and origin. A long list of previous owners on a young car, or a VIN that does not match the registration plate, both warrant caution.
Write-off status
Insurance Write-off Categories Explained: Cat A, B, S and N
A car marked Cat S or Cat N can legally return to the road after repair, whereas a Cat A or Cat B must be destroyed and should never be sold to you as a runner. This matters in Ireland because plenty of UK imports carry these markers and can quietly re-enter the market.
| Category | What it means | Can it legally drive again? | What it means for an Irish buyer |
|---|---|---|---|
| Cat A | Scrap only — total loss, entire vehicle | No — must be crushed | Walk away; it should not exist as a runner |
| Cat B | Body shell must be destroyed; some parts may be reused | No — must not return to road | Walk away; only parts are salvageable |
| Cat S | Structural damage, repairable | Yes, after proper repair | Insurable but worth far less; demand repair evidence |
| Cat N | Non-structural damage, repairable | Yes, after repair | Often fine, but negotiate hard on price |
Cat A and Cat B: Fit Only for Scrap
Cat A is the most severe: the whole car, parts included, must be crushed. Cat B allows some components to be recycled, but the body shell must be destroyed and the vehicle can never legally return to the road. Neither should ever be sold to you to drive.
Cat S and Cat N: Repairable but Negotiable
Cat S means structural damage — to the chassis or crumple zones — while Cat N covers non-structural damage such as electrics or cosmetics. Both can be repaired and re-driven, but they permanently reduce the car's value, so they should always translate into a lower price and proof of a proper repair.
UK & NI imports
Buying a UK or NI Import? Check the History Before You Count the VRT
For a car imported from the UK or Northern Ireland, always run the HPI check before you estimate the registration cost — there is no point calculating VRT on a car dragging outstanding finance or a Cat S past. The Central Statistics Office (CSO) records tens of thousands of used cars imported into Ireland every year, and with new car registrations up 3.3% in January 2026 (SIMI, 2026), imports stay competitive — but they add a step UK-focused guides skip.
Why Order Matters: History First, VRT Second
A cheap import only stays cheap if its history is clean. A car that looks like a bargain on a UK forecourt can carry unsettled finance or a hidden write-off that no price saving offsets. Verify the history first, and only then move to the VRT estimate — because a failed history check kills the deal regardless of how attractive the registration maths looks.
Example: A 2020 Mazda CX-5 2.2 Skyactiv-D Imported From the UK
Say you spot a 2020 Mazda CX-5 2.2 Skyactiv-D (diesel) imported from the UK. First, the HPI check; only then does the VRT estimate follow.
Step 1 — HPI check result
| Vehicle | 2020 Mazda CX-5 2.2 Skyactiv-D |
| Outstanding finance | Clear |
| Write-off marker | None |
| Mileage sequence | Rises in sequence |
Step 2 — then estimate the cost
| History check | Clean |
| VRT | Depends on OMSP set by Revenue |
| Import VAT, where it applies | 23% |
Only then do you turn to cost. Using the plate tool at the top of this page, you get an indicative registration figure to weigh against the asking price, remembering that Irish import VAT, where it applies, is 23% (Revenue), and that the VRT itself depends on the OMSP set by Revenue. Clean history first, cost second — in that order you make an informed decision, and the import stacks up.

HPI Check FAQ
Short answers to the questions Irish buyers most often ask once they understand the essentials.
Can I check a car history for free in Ireland?
Yes, for basics like make, model and tax status. But finance and write-off status — the findings that carry real financial risk — require a full report, not a free lookup.
Is buying from an HPI "trade" account or dealer safe?
A trade account or dealer is not a guarantee on its own. Always insist on seeing a current history report for the specific vehicle you are buying, dated and matched to its plate, rather than trusting a general assurance.
What should I do if the check shows outstanding finance?
Do not pay until the debt is proven cleared. Ask the seller for a settlement letter from the lender confirming the finance is settled, and hold off on any deposit until you have it in writing.
Does an HPI check replace a mechanical inspection?
No. A history check and a mechanical inspection are two separate, complementary steps: one confirms the paperwork and legal status, the other confirms the car's physical condition. You need both.
Does an HPI check cover cars imported from Northern Ireland?
Yes. Finance, write-off, theft and mileage records are checked against the car's VRM and VIN regardless of whether it last sat on a GB or Northern Ireland plate, which matters given how many used cars cross the border into the Republic.
How long is an HPI check valid for?
A report is only a snapshot of the moment it was run. Finance can be taken out, or a write-off recorded, the day after your check. For any car you are seriously close to buying, run the check again just before you hand over money.
Will an HPI check show if a car was previously a taxi or rental?
Sometimes, when that use was recorded against the vehicle by an insurer or fleet operator, but coverage is inconsistent and it is not a guaranteed field on every report. Ask the seller directly and cross-check the service history for high, evenly-spaced mileage typical of fleet use.
In Summary
An HPI check queries a car's registration and VIN against finance, write-off, theft and mileage records. Outstanding finance is the biggest legal risk — the lender can repossess a car you paid for in good faith — and Cat A/Cat B write-offs should never be sold to you as runners.
Run the check in the tool above before you commit to a UK or NI import. Read outstanding finance and write-off status first, cross-check the VIN against the logbook, and only then move on to estimating the VRT.
A clean HPI check reduces risk sharply, but it does not replace a mechanical inspection — treat the two as complementary steps, not substitutes for each other.
