Is the car safe to drive? Understanding insurance write-offs

An insurance write-off means the car has been damaged to the point where an insurer decided it was uneconomical to repair. While some write-offs are professionally repaired and returned to the road, many carry hidden structural weaknesses or are worth significantly less than equivalent undamaged vehicles. Sellers often omit this information entirely.

Understanding Write-Off Categories

  • Category A (Scrap): The car must be crushed in its entirety. It should never appear on the road under any circumstances.
  • Category B (Break): Can be stripped for parts, but the body shell must be destroyed. Like Cat A, it should never be driven.
  • Category S (Structural): The car suffered structural damage but has been repaired and returned to the road. Value is permanently reduced. Formerly known as Cat C.
  • Category N (Non-Structural): Cosmetic or electrical damage. Often safe if repaired correctly, but always check the quality of repairs and factor in the reduced resale value.

Sellers often "forget" to mention that a car is a Cat S or Cat N. A Cargeni report reveals the truth instantly from the Motor Insurance Anti-Fraud and Theft Register (MIAFTR) — the same data source used by professional dealers and insurers.

Important:

Always factor the write-off category into the price you negotiate. Cat S and Cat N cars should be priced noticeably below clean market value — if they are not, the seller is concealing the history.

Car Write-Off Check — Frequently Asked Questions

What does Cat S mean on a car?
Category S (formerly Cat C) means the vehicle suffered structural damage — to the chassis, crumple zones, or core frame — that an insurer declared uneconomical to repair. It has since been repaired and returned to the road, but carries a permanent write-off marker. Cat S cars are worth significantly less than undamaged equivalents of the same age and mileage.
What is the difference between Cat S and Cat N?
Cat S means structural damage to the chassis, crumple zones, pillars, or suspension mounting points. Cat N means non-structural damage — body panels, interior components, or electrical systems. Both categories result in an insurer declaring the car a write-off, but Cat N cars are generally safer to buy if the repairs were completed to a high standard.
Is it safe to buy a Cat S car?
It can be, provided the repairs were carried out by a reputable bodyshop using genuine manufacturer parts and the car has passed an independent structural inspection. That said, the resale value is permanently reduced, some insurers charge higher premiums, and you should pay substantially less than clean market value to account for these factors.
Should I buy a Cat N car?
Cat N cars can represent good value if the damage was minor and the repairs were completed properly. Always request original repair receipts and photos, inspect the quality of the bodywork yourself or have a mechanic do so, and factor the permanently reduced resale value into the price you're willing to pay.
How do I check if a car has been written off?
Enter the registration number above. Cargeni checks the Motor Insurance Anti-Fraud and Theft Register (MIAFTR) and insurance databases to reveal any write-off markers, the specific category (A, B, S, or N), and the date the record was created.
Can a Category A or Category B car be driven on the road?
Absolutely not. Category A cars must be crushed in their entirety and can never be used on a road. Category B cars must have their body shell destroyed, though individual mechanical parts can be salvaged. If you are offered a Cat A or Cat B vehicle for sale, do not buy it — report it to the DVSA and local police immediately.
Does a write-off marker affect car insurance costs?
Yes. Insurers view Cat S and Cat N vehicles as higher risk due to their repair history. Premiums are typically higher than for an undamaged equivalent, and some insurers refuse to cover them at standard rates or at all. Always obtain insurance quotes before committing to buy a write-off category vehicle.
