Not reliably with one check. GOV.UK's vehicle enquiry service does not list a write-off category, and the MOT history does not either. A private history check reports write-offs, but it can miss some, so confirm with the logbook, the MOT record and an engineer.
This guide is for UK buyers weighing a damaged or repaired car, including lots at salvage auctions where the seller declares a category.
What each check can and cannot tell you
| Check | What it shows | What it will not tell you |
|---|---|---|
| Private history check | Whether the car has been stolen, has outstanding finance, has a mileage discrepancy or was previously written off (per GOV.UK's consumer guide) | Anything about the quality of a repair |
| DVLA vehicle enquiry | Including tax, SORN, MOT expiry, first registration date, last V5C issue date, year, type approval category, weight, engine size, fuel, emissions and export status | A write-off category. GOV.UK's page does not list one |
| MOT history | Pass or fail, recorded mileage and next MOT due. For tests in England, Scotland and Wales, also what failed or had minor problems | A write-off category. GOV.UK's page does not list one |
| V5C log book | The vehicle details, including the VIN, to compare with the car and with DVLA's record | Whether the repair was done properly |
| Engineer's report | Structural damage and repair quality | Past ownership or finance |
The first three rows come from official sources. The last two are our own summary. The first row comes from the Department for Transport's consumer guide to repaired written-off vehicles. The second comes from GOV.UK's vehicle information service page. The third comes from GOV.UK's MOT history page.
Why a clean history check is not proof
A 2019 Auto Express investigation tested 10 cars sold at salvage auction as declared Cat S. None was flagged as a write-off by HPI or Experian AutoCheck checks. Both used a register called MIAFTR, run by the Motor Insurers' Bureau (MIB).
The MIB told the magazine that MIAFTR was never designed as a definitive register of every damaged vehicle. It said it was in early talks with DVLA, which holds a more comprehensive write-off database. DVLA said there were "no plans" to open that database to third-party companies.
That article is several years old. We could not find a current statement saying the gap is closed, so treat a clear result as a reason to keep checking, not a reason to stop.
Checking a car you are about to buy
Work through these in order:
- Run a private history check on the registration number. Choose a provider that states it covers write-off records, and read the category it reports. If you cannot get the registration number, you cannot run one, so factor that risk into your price or walk away.
- Compare it with what you were told. If a seller or listing says Cat N and the check says Cat S, or shows a category you were not told about, walk away or reprice.
- Check the VIN and the logbook. GOV.UK's consumer guide says the VIN on the car should match the VIN in the V5C, and the logbook details should match DVLA's records on the vehicle enquiry service.
- Read the MOT history. It shows past test results, failures and mileage. Look for repeated corrosion or structural advisories. GOV.UK's consumer guide suggests it for cars over three years old.
- Get an engineer's report if the damage was structural. GOV.UK's consumer guide advises having the vehicle inspected by an engineer who can identify structural damage, and suggests an independent check.
CarMargin AI's MOT history and DVLA check covers the mileage-against-MOT comparison on a lot page. It does not replace a paid write-off search.
At auction, the category is already declared
On a salvage auction lot the category is part of the listing, so you are not hunting for a hidden write-off. The question changes. Does the declared category match the damage in the photos, and does the history check agree with the listing? The listing is the seller's declaration. It is not an independent check.
Our Cat S vs Cat N guide explains how a car assessed as Cat N can still have damage that points to Cat S, and what that does to your resale price. A mismatch between photos and category is a pricing problem as well as a safety one, because your own buyer may run the same check on the car you sell.
After you buy: tell your insurer
GOV.UK's consumer guide says that if you do not tell your insurer a car was previously written off, the insurer can reject a claim for non-disclosure. Keep the repair photos and receipts. Our guide to getting a Cat S or N car back on the road covers the paperwork after purchase.
Checklist before you pay
- Registration number obtained and a private history check read in full.
- Declared category and check result agree.
- VIN on the car matches the V5C, and the V5C matches DVLA's record.
- MOT history read for advisories and mileage jumps.
- Engineer booked if the damage touched the structure.
- Price set with the category discount already in, not added afterwards.
