How to Check a Used Car's History in Ireland

NCT, finance, mileage, write-offs — what to check and where

Cars.ie Editorial Published 23 April 2026

Why Run a History Check?

A vehicle history check is one of the most important steps before buying any used car. It can reveal hidden problems that aren't visible during a viewing — outstanding finance, mileage tampering, accident damage, or theft. A check costs a fraction of the car's price and can save you thousands.

Cartell vs Motorcheck

Ireland has two main vehicle history check providers:

Cartell

  • Ireland's longest-running vehicle check service
  • Checks Irish and UK databases
  • Reports include: finance status, write-off history, mileage records, ownership changes, stolen status
  • Reports typically from around €20–€35 depending on the level of check (prices may vary — check cartell.ie for current pricing)

Motorcheck

  • Similar coverage to Cartell, with a presence in both Ireland and the UK
  • Checks Irish, UK, and Northern Ireland records
  • Reports include: finance, write-offs, mileage, stolen checks, taxi/hackney history, vehicle recalls, and a free car valuation with full reports
  • Includes a data guarantee up to €30,000 with every full report
  • Free basic car check available (identity verification only — does not include finance, mileage, or write-off data)
  • Full reports available at motorcheck.ie (check site for current pricing)

Recommendation: Either service is reliable. Some buyers run both for maximum coverage, as each may have slightly different data sources. At minimum, run one.

What a History Check Reveals

Outstanding Finance

This is the most critical check. If the car has outstanding HP (hire purchase) or PCP finance, the finance company — not the seller — is the legal owner of the vehicle. If you buy a car with outstanding finance:

  • The finance company can legally repossess it from you
  • You would lose both the car and the money you paid
  • This applies even if you bought in good faith with no knowledge of the finance

Always check finance status before purchasing, especially from private sellers.

Write-Off / Insurance Claims History

A “write-off” means an insurance company decided the car wasn't worth repairing relative to its value. Ireland uses four write-off categories:

Category Meaning Can it return to the road?
Category A Vehicle must be crushed entirely — no parts can be salvaged. End-of-life vehicle. No
Category B Vehicle cannot be repaired, but usable parts may be recycled. The structural framework must be crushed. No
Category C Vehicle is repairable, but the cost of repair exceeds the pre-accident value. Yes, if properly repaired
Category D Vehicle is repairable and economically viable to fix, but the insurer has chosen not to repair it (often due to risk of further hidden damage). Yes, if properly repaired

Important notes:

  • Irish history checks (Cartell/Motorcheck) only record Category A and B write-offs from the Irish market. There is no official Irish database for Category C and D write-offs.
  • UK imports will show all categories, including the newer UK designations Category S (structural damage, replaced the old Cat C in 2017) and Category N (non-structural damage, replaced Cat D). A history check on a UK import will flag these.
  • A previously written-off car isn't necessarily unsafe — Category C/D (or UK Cat S/N) vehicles may have had cosmetic or minor damage only. But it significantly affects resale value, and you should always have a repaired write-off independently inspected before buying.

Mileage Discrepancies (Clocking)

Clocking — winding back a car's odometer — remains a significant problem in the Irish used car market. A history check compares the current mileage against previously recorded readings from NCT tests, services, and insurance records.

Red flags for clocking:

  • Mileage significantly lower than expected for the car's age
  • Wear on steering wheel, pedals, and gear lever inconsistent with stated mileage
  • Service book stamps that stop suddenly
  • History check showing higher mileage at an earlier date

Stolen Vehicle Check

The check will flag if the vehicle has been reported stolen. If you unknowingly buy a stolen car, you have no legal right to keep it — it must be returned to the rightful owner or insurer.

NCT Status

You can check a vehicle's current NCT status for free online at ncts.ie. Simply enter the vehicle's registration number.

What to check:

  • Expiry date: When is the next NCT due?
  • Pass/fail history: Repeated failures on the same items may indicate a recurring problem
  • Mileage at each test: Compare against the car's current reading — this is a key clocking indicator

NCT Testing Schedule

  • Cars under 4 years old do not require an NCT
  • First NCT at 4 years old
  • Then every 2 years until the car is 10 years old
  • Then annually from 10 years onward
  • Cars aged 30–39 years (non-commercial) revert to every 2 years
  • Cars registered before 1 January 1980 (or that have reached their 40th anniversary) are exempt

VIN (Vehicle Identification Number) Check

The VIN is a unique 17-character code that identifies every vehicle. Check that:

  • The VIN on the car matches the VIN on the registration documents
  • The VIN plates haven't been tampered with (look for scratches, new rivets, or misalignment)
  • The VIN is typically found on the dashboard (visible through the windscreen) and on a plate in the door jamb

Additional Checks

Logbook (Vehicle Registration Certificate)

  • Confirm the seller's name matches the registered keeper
  • Check the car's details (colour, engine size, registration date) match the physical vehicle
  • If the seller isn't the registered owner, ask why — there may be a legitimate reason (selling for a family member) but it could also be a warning sign

Independent Mechanical Inspection

A history check covers the paper trail, but it won't tell you about mechanical condition. For peace of mind, especially on higher-value purchases, consider an independent pre-purchase inspection from:

  • A qualified motor engineer — find an accredited assessor through the Institute of Automotive Engineer Assessors (IAEA) website, which lists engineers by location across Ireland. Note: AA Ireland no longer offers its own pre-purchase inspection service and now refers customers to the IAEA.
  • Independent inspection services such as CarExperts Ireland (from approximately €149 for a 150-point check) or Car Inspections Ireland
  • A trusted local mechanic (expect to pay €100–€200 for a thorough check)
