In most cases, your insurer will pay the market value of your car immediately before the accident, fire or theft, minus any excess you owe. That is not necessarily what you paid for it, and it is not the price of a similar car on a dealer forecourt. The final figure depends on your policy wording, the car's condition and how the valuation is reached.
If your car is declared a total loss, the insurer is effectively buying it from you at its pre-loss value. Below we explain how that figure is worked out, what can push it down, and what you can do if the offer looks too low.
How insurers work out the value of a written off car
Insurers normally use trade valuation guides and recent adverts for comparable cars. They look at:
- Make, model, age and trim level of your car
- Mileage at the time of the loss
- Condition, including any existing damage, wear or faults
- Service history and MOT record, which can support a higher value
- Optional extras and modifications, if they were declared to your insurer
- Local and national market prices for similar cars at that time
Valuations are an estimate, so two insurers could land on slightly different figures for the same car. The offer is also usually closer to a retail-style market value than to a quick trade-in price, but this varies, so always ask how the figure was calculated.
When is a car declared a total loss?
A car is usually written off when the cost of repair, plus factors such as salvage value, is too high compared with what the car was worth. It can also be written off if it is judged unsafe to repair. There is no single fixed percentage that applies to every insurer or every car, so an older, lower-value car can be written off after relatively modest damage.
UK write-off categories
Insurers record total losses on the Motor Insurance Anti-Fraud and Theft Register (MIAFTR) using these categories:
- Cat A: scrap only. The car should be crushed and no parts can be reused.
- Cat B: the body shell must be crushed, but some parts can be salvaged.
- Cat S: structurally damaged but repairable.
- Cat N: non-structural damage, repairable.
Cat S and Cat N replaced the old Cat C and Cat D in October 2017. The category affects what the salvage is worth, and that can matter if you want to keep the car.
What can reduce your payout
- Your excess is normally deducted from a claim settlement.
- Undeclared modifications may not be valued, and in some cases could affect the claim itself.
- Poor condition or missing history can lower the valuation.
- Keeping the salvage means the insurer will deduct what the wreck is worth.
- Outstanding finance is settled first, so you may receive less than you expect, or nothing.
What if the car is on finance?
If you still owe money on a hire purchase or PCP agreement, the finance company owns the car until the agreement is settled. The insurer will generally pay the finance company first. If the payout is lower than your settlement figure, you are normally still responsible for the shortfall. GAP insurance, if you bought it, may cover some or all of that difference, so check the terms of your policy.
How to challenge a low valuation
You do not have to accept the first offer. You could:
- Ask the insurer for a written explanation of how the valuation was reached.
- Collect adverts for similar cars with comparable mileage, age and condition.
- Provide evidence of recent work, such as service invoices, new tyres, MOT certificates and photos taken before the loss.
- Point out any optional extras or specification details that may have been missed.
- Make a formal complaint if the insurer will not reconsider. If you remain unhappy after their final response, you may be able to refer the complaint to the Financial Ombudsman Service.
There is no guarantee of a higher figure, but well-documented evidence gives you the best chance of a fair review.
Can you keep a written off car?
Sometimes. If the car is Cat S or Cat N, you may be able to keep it and have the insurer deduct the salvage value from your payout. The car must be repaired to a roadworthy standard before it goes back on the road, and the write-off record stays with it for life. Cat A and Cat B cars cannot be put back on the road as they are. Some insurers also make it harder to insure a repaired write-off, so get quotes before you commit.
Buying a used car? Check for write-off history
If you are on the other side of this, buying a used car, the same records matter. A repaired Cat S or Cat N car can look perfectly normal, and a seller may not mention its past. Before you hand over any money, check the vehicle's registration on motorpeek.com to look for write-off records, along with other checks such as outstanding finance, stolen markers, MOT history and mileage discrepancies. No check can replace a thorough physical inspection, but it can help you spot problems early and negotiate with more confidence.
Remember that a write-off marker usually means a lower resale value, which is one reason sellers sometimes try to hide it. Ask for repair invoices and photos, and be wary of anyone who cannot explain the car's history clearly.
Frequently asked questions
Will insurance pay what I paid for my car if it is written off?
Not necessarily. Insurers usually pay the car's market value immediately before the loss, which could be higher or lower than your purchase price. Age, mileage, condition and market prices all affect the figure, and your excess is normally deducted.
Can I get more than the first offer from my insurer?
You can challenge it. Ask how the valuation was calculated, then send evidence such as adverts for similar cars, service records and receipts for recent work. If the insurer will not reconsider, you may be able to complain and then go to the Financial Ombudsman Service, though a higher payout is not guaranteed.
What happens to my written off car if I still owe finance?
The insurer will usually pay the finance company first, because it owns the car until the agreement is settled. If the payout does not cover what you owe, you may have to pay the shortfall yourself unless you have GAP insurance or a similar policy that covers it.
