Cat N auction car

When a vehicle is declared a ‘total loss’ after an accident, it will be put into one of four categories: A, B, S and N. Find out what Category N means, who decides whether a car is Cat N, and if it’s safe to buy a Cat N car.

What does Cat N mean?

Category N is one of four categories of write-off that insurance companies use to accurately determine the level of damage a vehicle has suffered. Cat N vehicles have sustained damage that is non-structural in nature. The damage does not affect the vehicle’s structural integrity, but the cumulative cost of repairing the vehicle still leads to it being written off.

Category N replaced the previous Cat D classification in 2017.

How cars get a category N classification

Your motor insurance company will make an assessment of the damage a vehicle has sustained after an accident. If they judge the damage to cost more to repair than they are prepared to pay, it will be deemed a write-off. Even though a vehicle may only have sustained cosmetic damage, like dents to bodywork, a Cat N status can still be applied if the insurance assessor judges that the total cost of the damage will cost more to repair than the current value of the car.

If your car is given a Category N classification, and you decide to keep it, you will need to inform the DVLA – but unlike a Cat S car, it won’t be de-registered.

What kind of damage qualifies as Cat N?

Cat N classification can include any superficial damage, including the following:

Issues with steering or brakes
Water damage
Bodywork scratches
Electrical faults

Structural damage (Cat S) is when a vehicle has suffered serious damage that compromises its safety or structural integrity, such as a crumpled chassis or cracked bulkhead. To get a Cat S vehicle back to roadworthy condition would take significant work by professional mechanics.

Who decides a car is Cat N?

Insurance companies employ vehicle assessors, who estimate if it is worth paying out for the cost of repairing cars involved in accidents. They will assign a write-off classification, from A to N. A means the car is only good for scrappage; B means parts can be salvaged, but the shell must be destroyed.

Is it safe to buy a Cat N car?

As long as you are diligent in your checks, and know what to look out for, it is possible and safe to buy a Cat N car.

Can I drive a Cat N car?

Yes, you can drive a Cat N car – and in fact, you don’t have to de-register it with the DVLA. As the damage might only be slight, Cat N cars might still be roadworthy, and they can stay on the road until their next MOT.

Repairing non-structural damage

When a vehicle is classified as Category N, it means that the car hasn’t sustained structural damage and the only repair work required is normally aesthetic. This means you might have to replace some bodywork, but this is something you could get a trusted local mechanic to do.

What to check before buying a Cat N vehicle

If you are buying a second hand car from a private dealer, you can check on its history by running an HPI check. This will tell you if a car has Cat S or N status, as well as other information, such as if it has been stolen or involved in an accident.

Should you buy a Cat N vehicle? Pros and cons

Pros

Cat N vehicles are cheap, for obvious reasons. Car dealerships must by law declare if a car they are selling is a Cat N or Cat S, so you can be more confident of the vehicle’s safety. Because the damage a Cat N car has sustained is not that serious, you also may not have to pay that much to bring it back to its former state.

Cons

There are fewer risks with buying a Cat N car than a Cat S. But because work by bodyshop specialists and independent garages is unregulated, you can’t be sure that a vehicle is 100% safe. Private sellers also don’t have to declare anything about a car’s history or write-off status.

You will also have to factor in that the insurance premiums on a Cat N car are much higher than an undamaged vehicle, and they lose their value more quickly.

Who buys Cat N cars?

Budget-conscious buyers appreciate the bargain they can pick up with a Cat N purchase. For those who know their way around repairing vehicles, Cat N cars can be a money spinner too. There are fewer risks for first-time car owners than with Cat S vehicles, but they still might want to be cautious when buying a Cat N.

Cat N v Cat S: What’s the difference?

Which is better: Cat N v Cat S?

While a Cat S write-off is a vehicle that has sustained structural damage, a Cat N vehicle is one that has no structural damage, with only bodywork requiring attention. This means that Cat N vehicles usually have only cosmetic damage following road accidents, with their overall structure and chassis remaining intact.

Although a Cat N vehicle is still deemed to be too expensive for insurers to repair, buyers of Cat N cars can realistically expect to get the vehicle back to being roadworthy.

Does Cat N affect insurance?

The insurance policy for your Cat N car will be ended by your insurer. You will need to seek new insurance quotes for your vehicle as a Cat N car. You will pay more on your monthly premiums, as insurers will deem it to be a greater risk to you and other road users than non-damaged vehicles.

Does Cat N show on a V5?

No, Cat N status is permanently recorded, but the vehicle can still be roadworthy.

Will a Cat N pass an MOT?
