Sell My Cat S or Cat N Car — Insurance Write-Off Valuation
Sell My Cat S or Cat N Car — Insurance Write-Off Valuation
If your car has been written off by an insurer and assigned Category S or Category N, you can still sell it — and it may be worth more than you think. Here's what the categories mean, how they affect value, and how to sell.
What Are Cat S and Cat N?
When an insurer declares a car a total loss (a "write-off"), it's assigned a category based on the type and severity of the damage. The categories changed in 2017 — the old Cat C and Cat D were replaced by Cat S and Cat N.
Category S (Structural Damage)
A Cat S write-off has structural damage — damage to the car's frame, chassis, or structural components. The car cannot be returned to the road without professional structural repair. Once repaired, it must pass an MOT before it can be driven legally.
Cat S replaced the old Category C.
Category N (Non-Structural Damage)
A Cat N write-off has non-structural damage — cosmetic or component damage that doesn't affect the car's structural integrity. This could include body panels, lights, brakes, or suspension. A Cat N car may be drivable without repair, though it should still be checked by a professional.
Cat N replaced the old Category D.
Key Difference
The key difference is whether the structure of the car has been damaged:
- Cat S = structural damage → requires structural repair before returning to the road
- Cat N = non-structural damage → may not need repair to be roadworthy
How Category Affects Value
A car's write-off category affects its value in several ways:
- Reduced market value — a categorised car is worth less than an equivalent uncategorised car, because buyers know it has been damaged
- Repair costs — if the car needs repair to be roadworthy (especially Cat S), the cost of that repair reduces the car's value
- Buyer pool — some buyers won't purchase categorised cars, which reduces demand and therefore price
- Insurance implications — insuring a categorised car can be more difficult or expensive, which affects the car's attractiveness
The exact impact on value depends on the car (make, model, age, mileage), the nature of the damage, and whether the car has been repaired since being categorised.
We don't provide percentage figures or typical discounts here, because the impact varies significantly by car and situation. The best way to find out what your specific car is worth is to get a valuation.
Can You Sell a Cat S or Cat N Car?
Yes. It's legal to sell a Cat S or Cat N car, as long as you declare the category to the buyer. The car can be sold:
- As-is (unrepaired) — to a buyer who will repair it or break it for parts
- After repair — if you've had the damage repaired and the car has a valid MOT
- To a car buyer — some online car buyers, including Fast Easy Car, consider write-offs
The key is transparency. You must tell the buyer about the category — failing to do so is fraud.
