Car Write Off: What It Means and How It Affects Your Insurance

If your car is badly damaged in an accident, your insurer may decide it’s a write-off. That doesn’t always mean the vehicle is a complete wreck - it could simply be too costly to repair compared with its market value. In this guide, we’ll explain what a write-off means, the official insurance categories, how the process works, and what it means for payouts, premiums and even buying or insuring a written-off car.

Key Points

• Cars are written off when repairs cost more than their value or they’re unsafe to fix.
• Four categories exist, from scrap-only to repairable (A, B, S, N).
• Payouts are based on market value minus your excess.
• Write-offs can affect premiums and financed cars.

What Is a Car Write Off?

A car is classed as a write-off when your insurer decides it’s not worth repairing. This usually happens for one of two reasons:

• Economic write-off: the repair bill would be higher than the car’s current market value. For example, if an older car worth £2,000 needs £3,000 of repairs, it will be declared a write off.
• Structural write-off: the car has suffered damage that makes it unsafe to put back on the road, even if repairs are possible. This often applies to cars with serious frame or chassis damage.

Write-offs aren’t just the result of major crashes. A flood, fire, or even a small accident on an older vehicle can also trigger one. When this happens, the insurer usually takes ownership of the vehicle and pays you a settlement based on its pre-accident market value.

Understanding the Car Write Off Categories

• Cat A – Scrap only, nothing can be salvaged.
• Cat B – Some parts can be salvaged, but the body must be crushed.
• Cat S – Structural damage, repairable but must be declared. Deemed uneconomical to repair by insurers, but it can be repaired. However, this will likely need to be professionally restored, inspected, and re-registered with the DVLA.
• Cat N – Non-structural damage, repairable and can return to the road.

Categories matter when buying or selling, as they affect value, safety, and insurability.

When Do Insurers Write Off Cars?

Insurers use professional assessors to compare repair costs with the car’s current market value and check whether it’s safe to repair. If the repairs approach or exceed about 50–60% of the car’s value, the vehicle may be declared a write off. In some cases, safety concerns alone - such as damage to the chassis-are enough to trigger a write-off, regardless of cost.

The Car Insurance Write Off Process

• Report the incident to your insurer. This starts the claims process and allows the insurer to arrange an inspection.
• Vehicle inspection. An assessor checks the damage and compares repair costs against the car’s value.
• Write-off category assigned. If the car is deemed a write off, you’ll be told why. You can read more in Why is my car a total loss/write-off?.
• Settlement offer. The insurer will offer compensation based on the vehicle’s pre-accident market value. If the car can’t be fixed safely, see What happens if my car isn’t repairable? for more detail.
• Payout. In straightforward cases, this is usually made within a few weeks.

Insurance Payouts and Premium Impact

When your car is written off, your insurer will usually pay you its pre-accident market value, minus your policy excess. This value is based on what similar cars are selling for at the time, not the price you originally paid.

If the car is on finance, the payout goes directly towards your outstanding balance. Depending on the settlement, you may still have money to pay.

A write-off claim can also affect the future cost of cover. Insurers can view drivers with a total-loss claim as higher risk, which means premiums may rise when you renew.

In some cases, you may be able to buy back a Cat S or Cat N vehicle, repair it, and get it reinsured. This can be cheaper in the short term, but resale values are lower and insurance can be more limited.

Can You Insure a Written-Off Car?

Whether or not you can insure a written off car depends on what category of write off it falls into and its condition:

• Cat S/N: These vehicles can be insured once they’ve been properly repaired and declared roadworthy with the DVLA. However, cover may be more limited and premiums higher, because insurers see them as higher risk.
• Cat A/B: These cars cannot legally go back on the road, so they can’t be insured.

If you’re thinking of insuring a repaired write-off, be aware of the limitations: resale value will be lower, not all insurers will cover the car, and you may need a specialist policy tailored for written-off vehicles.

Conclusion: Be Prepared and Protect Your Investment

A car write-off can be unsettling, but knowing how the process works makes it easier to handle. Understanding the categories, how payouts are calculated, and what your options are if your car is financed helps you plan ahead. If you’re considering buying back or insuring a written-off car, make sure you know the risks and limitations. Regularly reviewing your cover also means you’ll be prepared if the unexpected happens.
