Is my car a write-off? Cat S, Cat N and what happens next
Your car is a write-off when the insurer decides it can't be repaired safely, or that repairing it doesn't make sense compared with what the car is worth. You'll be offered a payout based on its market value just before the accident. The car is then put into one of the car write-off categories: A or B if it must never go back on the road, S or N if it can be repaired.
Insurers call it a total loss. At Newbridge Accident Repair Centre we're often the ones who have to tell an owner their car isn't worth repairing, and the next question is usually whether the insurer's figure is fair.
Car write-off categories: A, B, S and N
| Category | What it means | Back on the road? |
|---|---|---|
| Cat A | Scrap. The car can't be repaired and the whole thing is crushed. | No |
| Cat B | The body shell must be crushed, but some parts can be salvaged. | No |
| Cat S | Structural damage, for example to the chassis or crumple zones. | Yes, once properly repaired |
| Cat N | Non-structural damage, such as bumpers, panels or lights. | Yes |
The category stays on the car's record and shows up on history checks, so anyone buying it later can see it. You'll still come across the old Cat C and Cat D labels on older cars; S and N replaced them.
How an insurer decides it isn't worth repairing
The insurer weighs the cost of putting the car right against what the car is worth. On the repair side, that means the bodyshop's estimate plus what the claim costs while the car is off the road, such as storage and a hire car. On the other side is the car's market value, and the insurer also factors in what the damaged car would fetch as salvage. Each insurer sets its own threshold, and there's no single percentage that applies everywhere.
That's why older cars are written off so easily. We see this a lot: a front-end knock that doesn't look dramatic, but the airbags have gone off, and replacing them along with the sensors and trim around them costs more than an older car is worth.
What your payout is based on
The payout is based on the car's market value immediately before the accident: what it would cost to buy a similar car of the same make, model and age, with similar mileage, condition and specification. It isn't what you paid. It isn't the price of a new one either, unless your policy includes new car replacement cover and the car is young enough to qualify. On a fault claim, your excess comes off the figure.
How to challenge a low valuation
You don't have to accept the first offer. If it looks low:
- ask the insurer how they reached the figure and which sources they used
- find adverts for the same model, age, mileage and spec, and send screenshots
- send the service history, receipts for recent work such as new tyres or a cambelt, and details of any factory options
- put your case in writing and keep copies of everything
If the insurer won't move and you still think the figure is wrong, use its complaints process. After that, you can take it to the Financial Ombudsman Service, which handles complaints about insurers.
Can I keep a written-off car?
With Cat S or Cat N, usually yes. The insurer deducts the salvage value from your payout and you keep the car to repair. Cat A and Cat B cars can't be kept for the road.
Think it through first. The category stays with the car and pulls its value down when you come to sell. A Cat S car also needs a proper structural repair before it's driven again, which means checking and correcting the body alignment, not just bolting on new panels. If you're keeping one, get a repair quote before you agree to the deduction, so you know the numbers work.
If the accident wasn't your fault
You claim the car's value from the other driver's insurer, not your own. Through our non-fault accident claims service, independent insurance engineers inspect the car and, if repair isn't economical, provide a fair written valuation. There's no excess to pay and nothing goes on your own policy. We go after the rest of your losses for you, and you have a replacement car similar to yours in the meantime. How a non-fault write-off shows up when you renew is covered in will a non-fault accident affect my insurance?
A second opinion from Newbridge
If your insurer says the car's a write-off and you aren't sure, we can look at it. Sometimes our estimate comes out differently, for instance where a panel can be repaired rather than replaced. Sometimes we agree it isn't worth repairing, and we'll tell you that plainly.

Questions
01Does a write-off affect my no claims bonus?
If the accident was your fault, yes. A write-off is a claim like any other, and your no claims bonus will drop unless you've protected it. If it wasn't your fault and the full cost is recovered from the other driver's insurer, it shouldn't be affected. Either way, you'll need to declare the accident the next time you renew or get a quote.
02Is a Cat N car safe to drive?
It can be, once it's been repaired properly. Cat N means the insurer didn't find structural damage, so the chassis and crumple zones weren't the problem. The standard of the repair is what counts. If you're buying one, ask for photos of the original damage and the repair invoice, and have it checked over by someone independent first.
03What happens to my car once it's been written off?
It's collected by a salvage agent working for the insurer. Before it goes, take out everything that's yours, including the boot and door pockets, and if it has a private number plate, apply to DVLA to keep it, or you could lose the registration. The insurer will also ask for the V5C logbook and the keys.
04Will my insurer pay off my car finance if the car is written off?
The payout goes to the finance company first, up to what you owe. If the payout is less than the outstanding balance, you're still responsible for the difference unless you have GAP insurance, which is designed to cover that shortfall. If the payout is more than you owe, the rest comes to you. Speak to your finance company as soon as you know.
05Do I have to tell a new insurer my car is Cat S or Cat N?
Yes. Insurers ask whether a car has been written off, and the category shows up on history checks, so they'll usually find out anyway. Leaving it off can give them grounds to cut or refuse a later claim, or to cancel the policy. Some insurers charge more for a Cat S car and a few won't cover one, so shop around.
