How do I check if a car has been written off?
The four write-off categories
When an insurer decides a damaged car isn’t worth repairing, it pays out the car’s value and puts it in one of four categories. What happens next depends on the category:
| Category | Repair | Back on the road? |
|---|---|---|
| Cat A | Cannot be repaired | No — the whole vehicle has to be crushed |
| Cat B | Cannot be repaired | No — the body shell has to be crushed, but other parts can be salvaged |
| Cat S | Can be repaired after structural damage | Yes, once it's repaired to a roadworthy condition |
| Cat N | Can be repaired after non-structural damage | Yes, once it's repaired to a roadworthy condition |
Source: gov.uk, insurance write-offs. S and N replaced the older C and D in October 2017; a car written off before then can still carry one of those.
Where write-offs are recorded
The insurers’ register. Insurers record the cars they write off on the salvage and theft data held by the Motor Insurers’ Bureau. It was called MIAFTR; it now lives in MIB’s Navigate platform, and MIB has retired the old name. The category stays on the record for good. The public see it through vehicle history checks.
The V5C. If an owner keeps a Category S car after the payout, gov.uk says “DVLA will record the vehicle’s category in the log book”. An owner keeping a Category N car can keep the existing logbook, so a Cat N often isn’t on the V5C at all.
What isn’t recorded. The register holds what insurers report. A car repaired privately after an accident, without an insurance payout, can have a damage history and no write-off record — which is why the physical signs below still matter.
Free clues a car may have been written off
- The V5C. Look for a write-off category on the logbook.
- The MOT history. A long gap between tests means the car was off the road for a while — often for an innocent reason, sometimes after an accident. The free MOT history check shows every test date.
- The car itself. Paint that doesn’t quite match between panels, uneven gaps, paint on rubber seals or trim, newer glass or lights on an otherwise older car, or an airbag warning light. None of these proves a write-off; each is worth a question.
- The price. A repaired write-off is worth less, so one advertised well under similar cars should make you ask why.
- The seller. Ask directly whether it’s ever been an insurance write-off, and keep the answer in writing.
Scrapped cars
A Category A or B car should never be back on the road, and nor should a car that has been scrapped. When a vehicle is scrapped the keeper has to tell DVLA, and DVLA’s record shows it. If a car recorded as scrapped is offered for sale, it may be a clone, or a car rebuilt around a scrapped car’s identity. Our car check shows DVLA's scrapped marker.
Should you buy a Cat S or Cat N car?
It can be fine: many repaired write-offs are sound and cost less. The risk is the repair. Get an independent inspection, ask for photos of the damage and receipts for the work, check your insurance before you commit, and expect the lower value when you sell. Our guide to Cat S and Cat N write-offs goes through it in detail, and a service history check shows whether the work since went through a franchised dealer.
What our car check shows
- Outstanding finance, with the lender, the type of agreement, when it started and its term.
- Stolen: whether the car is recorded as stolen on the Police National Computer, with the police force to contact.
- Insurance write-offs: the category (A, B, S or N, or the older C and D), the date of the loss and where the damage was.
- Salvage auctions: any listing, with the lot description, damage, mileage and links to the auction photos where they exist.
- DVLA history: scrapped, exported and imported markers, plate changes, colour changes, the number of previous keepers and V5C logbook dates.
- Experian’s Data Guarantee: up to £10,000 for 12 months from the check if the finance, stolen or write-off data turns out to be wrong. The check must be run before you buy, and Experian’s terms apply.

It comes with Experian’s Data Guarantee: up to £10,000, or the car’s market value if lower, for 12 months from the check, if the finance, stolen or write-off data is wrong (Experian’s terms apply, and claims go to Experian).

FAQ
Frequently Asked Questions
How do I check if a car has been written off?
Run a write-off check on the registration: it reads the insurers' register and shows the category, the date of the loss and where the damage was. The V5C is a second clue — DVLA records a Category S on the logbook when the owner keeps the car — but a Category N often doesn't appear there, so the check is the reliable route.
How do I check if a car is Cat S or Cat N?
Our car check shows the category and the date of the loss. On the paperwork, a Cat S car that the owner kept has its category recorded on the V5C by DVLA; a Cat N often doesn't, because the owner can keep the existing logbook.
Is there a free write-off check?
Not of the insurers' register: it's used by insurers, the police and vehicle history companies, and the public reach it through paid checks. The free clues are the V5C, the MOT history and a careful look at the car.
What is a scrapped car check?
It shows whether DVLA records the vehicle as scrapped. A scrapped car should never be on the road again, so one offered for sale may be a clone or a car rebuilt around a scrapped car's identity. Our car check includes DVLA's scrapped marker.
Can a write-off marker be removed?
No. The category stays on the vehicle's record after it's repaired, which is why a repaired write-off is worth less when you come to sell it too.
Do I need to tell my insurer a car is a repaired write-off?
Yes. Insurers ask, and a wrong answer can affect a claim. Some insurers won't cover a repaired Cat S and others charge more, so get a quote before you buy.
What were Cat C and Cat D?
The categories before October 2017. They were about cost — whether a repair cost more or less than the car was worth — where S and N are about where the damage was. A car written off before then can still carry a Cat C or Cat D marker.
Does a service history check show write-offs?
No. It shows the manufacturer's dealer service records — useful for seeing whether work after an accident went through a franchised dealer, but it doesn't read the write-off register. Our car check does, and the two can go in one report.
