What is a Category N Write-off?

You've found a great deal on a used car, but the listing mentions it's a "Category N" write-off. What does that mean, and should you buy it?

What does Category N mean?

A Category N (Cat N) write-off means the vehicle has suffered damage that the insurance company deemed uneconomical to repair, but critically, the damage is Non-structural. Before October 2017, this was known as a Category D write-off.

Unlike a Cat S (Structural) write-off, the vehicle's structural frame or chassis remains intact. The damage might be cosmetic (scraped panels, cracked bumpers) or electrical (flood damage to wiring, stolen infotainment systems).

Why do insurers write off cars for cosmetic damage?

Insurance companies must repair cars using brand-new, original manufacturer parts and approved labor rates. If a car is worth £3,000, and it needs a new genuine bumper, headlight, and paintwork costing £2,500, the insurer will write it off. An independent garage or a DIY mechanic might be able to source used parts and fix it safely for £800.

Should you buy a Category N car?

A Cat N vehicle may be priced differently from a comparable vehicle without a recorded write-off marker, but prices vary with the vehicle and its condition. Consider the repair history and independent inspection before deciding:

1. Verify the damage

Ask for pre-repair photographs and invoices for the work done. A Full Vehicle History Check may report a write-off marker and recorded date where available; it cannot assess the damage or verify the quality of repairs, so arrange an appropriate independent inspection.

2. Insurance implications

While easier to insure than a Cat S, some insurance companies may still charge a higher premium for a Cat N car, or refuse to pay out the full market value if it gets written off again.

3. Resale value

Just as you are buying the car at a discount, you will have to sell it at a discount. Bear this in mind if you plan to upgrade in a year or two.
