What Is An Insurance Write-Off?

An insurance write-off is when a car is damaged to a point where it is either no longer roadworthy or repairing it makes no financial sense. In a write-off, your insurance company will pay you the current value of the car instead of repairing it. In order to know how serious the write-off is, your car will be assigned to a specific category. We’ve taken a look at each below.

What Are The Different Insurance Write-Off Categories?

There are six write-off categories, all varying in how damaged your car is. Let’s break down each category.

• Category A - Category A is the worst level of write-off there is. At this point, the car is beyond repair and needs to be crushed.
• Category B - This is when the main part of the car is damaged but other parts can be salvaged.
• Category C - The car can be repaired but repairing it will cost more than what the car is worth.
• Category D - You can repair the car for less than it’s worth but transporting it for repairs might end up costing more than the car is worth.
• Category N - The car hasn’t suffered any major structural damage but must be repaired to make it roadworthy.
• Category S - The car has suffered structural damage but can be repaired. It will need to be repaired to be ready for the road.

What Is Cat S?

A Cat S car can be driven on the road again but will need repairs to make it roadworthy. The S itself stands for structural damage, but it can be repaired. Damage will likely have occurred to the chassis or suspension, but the important thing is that it can be fixed. Once the car is fixed, it’s important to remember that your car needs to be re-registered with the DVLA. Not doing this could lead to you receiving a fine. AutoTrader have listed some of the more common category s write-offs.

• Car chassis or frame damage.
• Damage to the frame of the car.
• Suspension damage.
• Severe roof damage.
• Damage to the floor pan.
• A severe front or rear-end collision causing structural damage.

What Is Cat N?

Cat N cars have suffered damage, but these aren’t structural. However, if the car is to be driven on the road, it will need to undergo repairs. Again, the car will need to be re-registered with the DVLA, or you could face a hefty fine. AutoTrader has detailed some of the more common examples of a Cat N write-off.

• Cosmetic damage like dents and scratches.
• Electrical issues like wiring.
• Interior damage like damaged seating and water damage.
• Damage to non-structural components.
• Engine and gearbox issues.
• Damage to windows or windscreen.
• Damage to the exhaust or catalytic converter.
• Cosmetic fire damage.

What Are the Differences Between Cat N And Cat S?

The main difference between a Cat N car and a Cat S car is the level of damage. In a Cat N car, non-structural damage has occurred. Whereas for a Cat S car, structural damage has occurred. Both can be driven on the road again but will need repairs in order to be road-worthy. Cat N issues tend to be more cosmetic, and Cat S issues more structural.

Should I Buy A Car That’s Previously Been Written Off?

You can buy a car that’s been written off in the past, but you should always request an inspection before making the final decision. Cars that can be bought after undergoing a write-off fall in the categories C,D,N, and S. Therefore, when it comes to making a car purchase, if you notice a previous write-off, it is best practice to request a full inspection of the car to make sure all previous issues are resolved. Alternatively, you can bring a mechanic with you to inspect the car in person.

Conclusion

Write-offs happen, and this doesn’t necessarily mean that the car is ruined. For Cat A and B, the car is unfortunately unrecoverable, but for the other categories, C,D,N and S, the car can get back to being road ready. If you are about to buy a car and spot a past write-off, don’t panic. Order an inspection of the car to make sure all previous issues are corrected, and if they are, you can go ahead and buy your car!
