What is a reg check?
A reg check is a vehicle registration lookup that uses a UK number plate to reveal important car information. It is one of the quickest ways to check a used vehicle before you travel to view it, pay a deposit or complete a purchase.
Most buyers start with a free check to confirm basic information such as make, model, MOT history, tax status and mileage records. A full report goes further by checking risk markers that may not be obvious from the advert or logbook, including outstanding finance, stolen records, write-off history, plate changes and mileage discrepancies.
This is especially useful when buying privately, because the seller may not know or disclose the full background of the vehicle. A clean-looking car can still have hidden finance, previous accident damage, mileage problems or identity issues.
Full vehicle history check for used car buyers
A full report is recommended before buying a used vehicle because it can reveal hidden history that may affect safety, value or ownership.
- Outstanding finance check: See whether a vehicle may have a current finance agreement registered against it.
- Written-off check: Find out whether the vehicle has been recorded as an insurance write-off.
- Stolen vehicle check: Check for stolen markers from relevant police and insurance data sources.
- Previous keeper check: Review the number of previous keepers recorded for the vehicle where available.
- Mileage check: Identify possible mileage discrepancies using available MOT and history records.
- Vehicle identity checks: Review plate changes, import/export markers, scrapped status, colour changes, VIN/chassis data and engine number where available.
Why check a used car before buying?
A used car advert only tells you what the seller wants to show. A vehicle history check helps you compare the advert against independent data so you can spot possible problems before handing over money.
| Used car risk | Buying without a check | Buying with a vehicle report |
|---|---|---|
| Outstanding finance | You may not know if money is still owed. | A full check can reveal finance markers. |
| Stolen vehicle | The car may look legitimate. | A full report can highlight stolen records. |
| Insurance write-off | Previous damage may not be obvious. | Write-off history can be revealed. |
| Mileage fraud | The odometer may not tell the full story. | Mileage records can highlight discrepancies. |
| Vehicle identity | Plate changes or identity issues may be missed. | Vehicle identity data helps you compare details. |
