MOT guides
Write-off categories: A, B, S and N explained
A written-off car is not always a no-go — but you must know which category it was. Here is what each one means.
The categories
- Category A: scrap only. The entire vehicle must be crushed, including all parts.
- Category B: the body shell must be crushed, but some parts can be reused. Never to return to the road as a whole vehicle.
- Category S: structurally damaged but repairable. Can be returned to the road after proper repair.
- Category N: non-structural damage (for example electrical, cosmetic). Repairable and roadworthy.
Categories S and N replaced the old C and D categories in October 2017. A Cat S or N car can be a sensible buy if repaired correctly and priced to reflect its history — but always get an independent inspection.
How to check
Write-off status comes from insurance records, which MOTIntel does not hold. For a confirmed write-off and finance check, use a paid provenance provider; use MOTIntel free for the MOT history, mileage record and next-MOT risk. See what we do and do not check.
