Car write-off categories and what they mean
Key takeaways
- A car is a write-off when repair costs are higher than (or close to) its market value
- Insurers classify write-offs into four categories (A, B, S, N) depending on damage severity
- You’re usually paid the car’s pre-accident market value, minus excess and any finance
- Write-offs can affect your no-claims bonus (NCB) and future insurance premiums
- Category S and N cars can often be repaired and reinsured if made roadworthy
What does it mean when your car is a write-off?
A car is classed as a write-off (or “total loss”) when your insurer decides it isn’t worth repairing after it’s been damaged. This can happen if the cost of fixing the vehicle is higher than its market value, or close enough that repairing it wouldn’t be economical.
Your insurer will arrange for the car to be inspected, usually by a loss adjuster or engineer. They assess the damage, estimate the repair costs and compare this to what the car was worth before the incident.
If the vehicle is written off, it will be given a category (such as Cat A, B, S or N) which explains the level of damage and whether it can legally return to the road.
What makes a car a write-off?
A car becomes a write-off when the insurer decides that repairing it isn’t financially practical. This decision is usually based on:
- The estimated cost of repairs
- The car’s market value before it was damaged
- Whether the vehicle can be safely and economically returned to the road
An engineer or loss adjuster will:
- Assess the damage
- Estimate the total repair costs
- Compare these costs with the vehicle’s pre-incident value
If repair costs exceed - or come close to - the vehicle’s value, the insurer will usually declare it a total loss instead of repairing it.
What are the different write-off categories?
When a car is written off, it is placed into one of four car insurance categories, Cat A, Cat B, Cat S, and Cat N. These categories explain how badly the vehicle is damaged and whether it can be repaired or used again.
| Categories | Description |
|---|---|
| Category A (Scrap) | The vehicle is so severely damaged that it must be crushed. No parts can be salvaged, and it can never return to the road. |
| Category B (Break) | The car cannot be driven again, but some parts may be removed and reused. The remaining shell must be scrapped. |
| Category S (Structural damage) | The car has sustained structural damage, such as to the chassis or frame, but it can be repaired and returned to the road if fixed properly and declared roadworthy. |
| Category N (Non-structural damage) | The damage does not affect the structural integrity of the vehicle. This may include cosmetic or electrical issues. The car can be repaired and driven again once it is safe to do so. |
What happens if my car is declared a write-off?
If your car has been in a car accident or damaged, for example, in a storm or a flood, the first thing to do is to inform your insurer. Your insurance provider will then inspect the vehicle to determine if it is safe to drive again.
If your insurer decides the car is not salvageable or it would cost more than its value to be made roadworthy again, your car will be deemed a write-off or ‘total loss’.
What is the car insurance write-off procedure?
The write-off process usually follows a set of steps after your car has been damaged:
- Report the claim: Contact your insurer as soon as possible after the incident.
- Damage assessment: An engineer or loss adjuster inspects the vehicle, either in person or remotely, to assess the extent of the damage.
- Cost evaluation: The insurer compares the estimated repair costs with the car’s pre-incident market value.
- Write-off decision: If repairs aren’t economical, the vehicle is declared a total loss and assigned a write-off category.
- Settlement offer: You receive a payment based on the market value of the car (minus any excess or outstanding finance).
- Vehicle disposal: The insurer typically takes ownership of the vehicle and arranges salvage or scrapping, unless you choose to retain it where permitted.
What happens to my insurance when my car is written off?
- The vehicle is removed from your policy: Once your claim is settled and ownership of the written-off car is transferred to the insurer, it will be removed from your policy.
- Your policy may stay active: If you have other vehicles insured under the same policy, your cover will continue, but your premium will be recalculated based on the remaining vehicles.
- Impact on your no-claims bonus (NCB): A total loss claim will usually affect your NCB, even if you weren’t at fault. This remains the case until the claim is fully settled and the insurer has recovered their costs, where applicable.
- Future premiums: When you insure a replacement or new vehicle, your premium is likely to be higher due to having a significant claim on your record.
If my car is written off, how much will I get?
Your insurer’s payout should be enough to replace your car with a similar vehicle in a similar condition in your area, normally with the car insurance excess deducted. The settlement you’ll receive will depend on what the assessor agrees the car was worth before it was damaged.
Be warned that it is unlikely you will get the same value as you paid for it.
What if I don't agree with the write-off decision?
Most insurers will have room for a second, slightly higher offer if you negotiate. To help you negotiate, consider the following:
- Research the prices of vehicles of a similar age and mileage – online or in motor trade magazines
- Make sure anything you have done which may have increased its value – such as new tyres or a stereo - is taken into account.
- You can also pay for an engineer’s report to independently value your car.
If you and your insurer cannot come to an agreement, you can complain and then take your case to the Financial Ombudsman Service. The value of write-offs is a major source of complaints, and the ombudsman upholds about half of all complaints.
The ABI/Lloyd’s Salvage Code says, “In the event of a dispute between the insurer and other interested parties regarding categorisation, the matter should be escalated to an appropriately qualified person who assumes responsibility for the final decision.”
Should I buy a written-off car?
Buying a written-off car can be a way to save money, but it comes with important risks and responsibilities you need to understand before committing.
| Pros of buying a written-off car | Cons of buying a written-off car |
|---|---|
| Lower purchase price compared to similar non-written-off cars | Reduced resale value, even after repairs |
| Potential to get a higher-spec vehicle for your budget | Risk of hidden damage or future reliability issues |
| Category N and S cars can be safe once properly repaired | Potentially higher insurance costs or limited cover options |
Category A and B cars should be scrapped, so they are generally best avoided (except for parts in the case of Category B). Category N and S vehicles, however, can return to the road safely once they have been professionally repaired.
Once repaired, the car may need to be re-registered with the DVLA and must pass an MOT to confirm it is roadworthy. It’s important to check with the seller whether this has already been done or if the vehicle is still a project car.
Even after repair, written-off vehicles usually have a lower market value than equivalent cars with a clean history, so it’s worth factoring this into your decision.
Can I get insurance for a written-off car?
It is possible to insure some written-off cars, but only if they have been properly repaired and are safe to drive.
To insure a written-off vehicle:
- Only Category S and Category N cars are usually insurable
- The vehicle must be fully repaired and declared roadworthy
- You must tell the insurer about its write-off status when getting a quote
Even when insurance is available, premiums may be higher, or fewer insurers may offer cover. Comparing policies is the easiest way to find out whether you can get cover for a previously written-off car and see which insurers may be willing to insure it.
