What to do if your car is written off

Insurers call a write-off a total loss. The Financial Ombudsman Service gives the two triggers plainly: the vehicle is not worth the cost of repairing it, or it has been stolen and never found. Neither is a safety judgement in the first instance. A structurally sound car with a cracked bumper, a deployed airbag and a bent tailgate can be a total loss because parts and labour exceed what it was worth, while a far more damaged car worth ten times as much is repaired. The threshold is economic, which is why cheap older cars are written off for damage that looks trivial.

Once the vehicle is declared a total loss, the insurer's engineer applies a salvage category. GOV.UK sets out four. Category A means the damage is so severe that the vehicle cannot be repaired and the entire thing must be crushed, with no parts salvaged. Category B means the vehicle itself cannot be repaired and the body shell must be crushed, though mechanical and electrical parts may be reclaimed and reused. Category S means structural damage that can be repaired. Category N means non-structural damage — cosmetic, electrical or mechanical — that can be repaired.

The Department for Transport's consumer guide to buying repaired write-offs draws the line differently and more usefully. Categories A and B are actual losses: vehicles that cannot or should not be repaired, and which will not be re-registered by DVLA. Categories S and N are constructive losses, where the repair cost exceeded the replacement value at the time but the vehicle may often be subsequently repaired and returned to the road. If your car is a Cat S or Cat N, keeping it is a real option. If it is Cat A or Cat B, it is not, and no amount of arguing changes that.

The categorisation is the insurer's decision, taken by its engineer, not DVLA's and not a government body's. DVLA's role comes afterwards: it is notified, and it records the category against the vehicle. Regulation 15A of the Road Vehicles (Registration and Licensing) Regulations 2002, as amended in 2018, is the mechanism — it deals with what happens to a registration document once an insurer has informed the Secretary of State that a vehicle has sustained damage, and it applies to cars, small goods vehicles and certain two and three-wheel vehicles.

That record is permanent. A Cat S or Cat N marker follows the vehicle for life, appears on history checks, and depresses what it will sell for even after a faultless repair. It also affects insurability — the Department for Transport's guide warns that not all insurers will automatically provide cover on a repaired write-off, and that failing to tell an insurer about the history can cost you a future claim.

Keep the two decisions apart from the start. Whether the car is a total loss and what category it gets is one conversation, generally short. What the car was worth is a different conversation, and it is the one worth having. Insurers often present both as a single settled outcome in the same phone call, which is how people accept a number they never examined.

The single most useful sentence in this whole area comes from the Financial Ombudsman Service's guidance to insurers: the market value is the price the vehicle would have sold for at a reputable dealership immediately before it was damaged or stolen. Not what a trader would have given you in part-exchange. Not the auction figure. Not a private-sale figure. The test is what it would have cost you to walk into a dealership and replace the car with its equivalent, and that number is materially higher than trade in almost every case.

To decide whether an insurer's figure is fair, the Ombudsman compares it with prices in online motor valuation guides — it names AutoTrader, CAP, Percayso and Glass's. Where the guides all give a similar value and the insurer's offer is in line with them, the Ombudsman is likely to agree with it. Where the guides vary significantly, the position shifts sharply in the consumer's favour: if the insurer's valuation is not at or very close to the highest guide, it must be supported by other evidence, and if it is not, the Ombudsman is likely to tell the insurer to settle at the highest guide value.

The Financial Conduct Authority's March 2024 multi-firm review pushed the same standard onto firms directly. It found that all the firms reviewed used retail transacted valuations from one or more trade guides, but warned against relying on a single guide, and said it expects firms to follow the Ombudsman's approach. It grounded that in existing rules rather than new ones — ICOBS 8.1.1R requires an insurer to handle claims promptly and fairly, to provide reasonable guidance and information on progress, not to unreasonably reject a claim and to settle promptly once terms are agreed.

The FCA also named the tactic. It found that some firms made low initial offers in the expectation of pushback, and said the practice can lead to systematically different outcomes for different customers largely based on their propensity to challenge or complain. In its accompanying press release it said some firms were only increasing offers when a customer complained, and told consumers who believe they have been undervalued to complain to the insurer and then take it to the Financial Ombudsman Service.

The guides do not cover everything, and the Ombudsman says so. Vehicles over 20 years old — sometimes less for particular models — unusual vehicles such as agricultural machinery, and conversions like campers and ice-cream vans often fall outside them. Where the guides cannot produce a fair figure, the Ombudsman asks both sides for other evidence, typically an engineer's report. If you own something the guides cannot price, expect to build the valuation yourself.

One thing that is not evidence is the value you declared when you bought the policy. The Ombudsman states directly that although you may have been asked to estimate your vehicle's value on the application form, that is not the amount the insurer would have to pay out on a claim. Insurers occasionally raise it. It does not set a ceiling, and the Ombudsman would not expect a valuation to be limited by it unless it was made clear at the point of sale that it would be.

Start by asking for the workings, in writing, before you argue about the number. Ask which valuation guides were used, what figure each returned, what mileage and specification were entered, and what deductions have been applied and why. The Ombudsman's guidance to insurers makes the point that valuations in dispute are often based on the wrong details, and tells firms to check the vehicle's details have been recorded correctly. A trim level, an engine size or a mileage entered wrongly moves the guide price on its own, and that is the cheapest correction available to you.

Then build the adverts. The Ombudsman historically placed little weight on advertised prices because cars tended to sell below them, but has changed position: the guides now report that cars sell at or close to advertised prices, so adverts are considered. The condition attached is strict. They must be like-for-like, because small variations matter — the Ombudsman singles out differences in mileage and year of registration as having a big effect on the value of the same model. Match the model, trim, engine, transmission, fuel, year and mileage as closely as you can, capture the full advert with the date and the dealer, and send three rather than one.

If you bought the car second-hand shortly before the claim, say so and produce the receipt. The Ombudsman still expects the insurer to use the guides as a starting point, but says it should take into account what you recently paid. Where you paid more than the guides suggest, the question becomes whether that was a fair market price, and other evidence is weighed. It is not automatic, but a dated invoice from a dealer three months before the accident is far stronger than an argument about condition.

Be realistic about modifications and extras, because this is where people waste effort. The Ombudsman's view is that many modifications and optional extras have little effect on second-hand value compared with guide prices — a satnav, or work done to keep the car roadworthy such as an engine replacement. Spoilers and sports exhausts may appeal to some buyers and put others off, so on balance the market value may not be any higher. Occasionally the quality of an accessory does add value, but the Ombudsman notes those vehicles are usually insured on an agreed-value basis instead.

If you hold an agreed-value policy, the argument is different and much shorter. Those policies, normally used for valuable or classic vehicles, require the insurer to pay a previously agreed amount, and the Ombudsman expects that amount to be paid on a total loss because the premium was assessed on it. Check the schedule before you engage with a market-value discussion at all.

Two specific traps are worth knowing. If the vehicle is commercial — a van, typically — VAT is due on a replacement from a dealer, and the Ombudsman says that where the policyholder is not VAT registered the settlement should usually include VAT; where there is doubt, the insurer must show it has allowed for it. And if the car was new or under 12 months old, most policies replace it rather than pay market value where the repair cost exceeds 60% to 70% of the current list price. If the insurer says the repair cost falls under that threshold, the Ombudsman checks the repair cost has been worked out fairly.

Wear and tear is the deduction to challenge first. The FCA's review said firms should not, as part of a standard valuation process, deduct for wear and tear that would reasonably be expected for a vehicle of similar age and mileage, because that is already reflected in the guide price. The Ombudsman puts it from the other end: it is unlikely to agree with a lower valuation where the engineer has given no specific reasons, or for wear and tear that would be expected in a car of that age. A deduction with no named defect attached to it is the weakest thing an insurer can send you.

Pre-existing damage is legitimate in principle and often overstated in practice. The Ombudsman will only treat a reduction as fair where the pre-existing damage would actually have affected the vehicle's market value, and gives a clean illustration: small scratches might affect the value of a brand new vehicle but not one that is 15 years old. Ask what the damage was, what it would have cost to repair, and how that translates into the sum deducted. If the answer is a percentage rather than a repair estimate, push back.

A missing MOT is a real vulnerability. The Ombudsman says that if it finds the vehicle did not have a valid MOT and would have failed one, a small deduction from the valuation is probably fair. The related point is broader and more serious: most policies require the vehicle to be maintained in a roadworthy state, and where an insurer rejects a claim on that basis the Ombudsman looks for evidence that the loss or damage was caused or significantly affected by it. ICOBS makes it unreasonable to reject a claim for breach of a warranty or condition unless the circumstances of the claim are connected to the breach.

A previous write-off is the deduction with the most movement in it. The Ombudsman's position turns on knowledge. If you knew, or reasonably should have known, that you were buying a repaired write-off, a deduction may be fair — but the insurer must show what impact the previous total loss actually had on market value. If it is reasonable that you did not know about the vehicle's history when you bought it, the Ombudsman is likely to say you should be paid the full market value. The FCA specifically criticised firms applying a standard deduction, often around 20%, without considering individual circumstances.

Left-hand drive and imports usually justify something. Left-hand-drive vehicles are generally worth less in the UK, so the Ombudsman would normally accept a deduction reflecting the difference against a right-hand-drive equivalent, and the same logic applies to imported right-hand-drive cars. But the insurer must produce supporting evidence that the deduction is fair, and the position reverses for classics, where left-hand drive may be a feature to a specialist market and the car is often on an agreed-value policy anyway.

Finally, separate deductions from the valuation itself. Your policy excess comes off the settlement, and if the accident was not your fault your excess is one of the uninsured losses Citizens Advice says you can pursue from the other driver's insurer, alongside alternative transport, loss of earnings and personal injury. A comprehensive policyholder can also lose the no-claims discount where the insurer cannot recover from the other side. None of that is an argument about what the car was worth, and mixing the two weakens both.

Say early and in writing that you want to keep the vehicle, before you agree to anything else. GOV.UK confirms you can keep a Category N or Category S vehicle where the insurer pays out and sells the salvage back to you. Category A and Category B are not available on any terms — those vehicles must be destroyed and DVLA will not re-register them. The Ombudsman hears from people whose cars were scrapped before they realised keeping them was possible, and its position is that it is not fair to scrap a vehicle without warning; it checks whether the owner told the insurer they wanted to keep the salvage.

The arithmetic of keeping it is straightforward and worth understanding before you ask. The insurer pays the full market value and deducts what it would have received for selling the salvage. The Ombudsman treats that as normally fair — but it asks the insurer for evidence to prove how much the salvage would have made. If the deduction arrives as a round percentage with no supporting figure, that is a challengeable number in exactly the same way an unexplained condition deduction is.

Get your possessions and your private plate out before the vehicle leaves. The Ombudsman deals with people who lost items inside a scrapped car and can require compensation for them, but recovering an object is easier than being compensated for it. A personalised registration must be retained or transferred while you can still act on the vehicle; once it has gone to salvage that becomes much harder.

The paperwork differs if you keep it. GOV.UK's instruction for a Category S vehicle is that you send the complete log book to your insurer and then apply for a duplicate using form V62. That is a postal application, not the online duplicate route, and it takes correspondingly longer. Build that delay into any plan that involves repairing and taxing the car quickly, because a vehicle cannot be taxed or sold cleanly without a registration document in your name.

Repairing it properly is a separate discipline from getting it through an MOT. An MOT is a roadworthiness test on the day, not a certificate that structural repairs were done to standard, and the Department for Transport's consumer guide recommends a report from an independent expert and checking that VINs match the documentation. If you would insist on that before buying somebody else's repaired Cat S, apply it to your own.

Tell your insurer before you insure it, not after. The consumer guide is blunt that not all insurers will automatically provide cover on a repaired write-off, and that you should inform your insurer once you have bought one to avoid a claim being rejected later. The same applies to the car you have just bought back from your own insurer — it is a different vehicle on the record from the one you insured last year, and the record now says so.

If the car is on hire purchase or a personal contract purchase, you are not the owner. The Financial Ombudsman states the position directly in the context of new-vehicle replacements: the finance company is the owner of the vehicle until the final payment is made. That has an immediate consequence on a total loss — the settlement is paid towards the finance agreement first, and you receive only what is left over, if anything. It also means the finance company is a party to decisions about replacement vehicles, and the Ombudsman expects an insurer to provide a new-vehicle replacement under a policy term as long as the finance company agrees.

Where the settlement is less than the outstanding balance, the difference does not disappear. You still owe it, and it is owed to the lender rather than to the insurer, which is why people are surprised to find themselves paying for a car that no longer exists. This is the gap that GAP insurance was designed for. The FCA describes GAP as cover for a financial shortfall that can arise when a customer's vehicle is written off or stolen and the insurance payout does not cover the original purchase price or the remaining finance.

Check what you actually bought, because GAP is not one product. Some policies pay the difference between the insurer's settlement and the price you originally paid; others pay the difference between the settlement and the outstanding finance balance; others fund a replacement vehicle. They pay different amounts on the same claim. Read the schedule and the claims conditions before you agree a settlement figure with the motor insurer, because a low motor settlement can transfer straight onto the GAP insurer, and both will be interested in the number.

The FCA has been unusually active on GAP. In February 2024 it asked firms accounting for around 80% of the market to pause sales, after finding that only 6% of the amount customers paid in premiums was paid out in claims and that some firms paid up to 70% of premium value in commission to those selling the policies. The read-across is that a GAP policy bought before that intervention is worth reading closely rather than assuming it does what the salesperson said.

The valuation fight matters more, not less, when finance is involved. Every pound added to the motor settlement is a pound off the shortfall, and the same evidence pack works on both. Where the GAP insurer is also regulated, both complaints run to the same place — a final response from each firm, then the Financial Ombudsman Service.

If the accident was not your fault and the other driver was uninsured or untraced, the Motor Insurers' Bureau exists for that situation and handles claims from victims of uninsured, hit-and-run and foreign-registered drivers. Citizens Advice also sets out the uninsured losses you can pursue directly from an at-fault driver's insurer, including the excess, alternative transport, loss of earnings and personal injury — none of which your own comprehensive settlement covers.

Telling DVLA the vehicle has been written off is your responsibility, not the insurer's, and GOV.UK states that you can be fined £1,000 if you do not. It is quick, and the required details are specific: your insurance company's name and postcode, the vehicle registration number, and the 11-digit reference number from the yellow 'sell, transfer or part-exchange your vehicle to the motor trade' section of the V5C log book.

Check the log book before you send anything. GOV.UK tells you to make sure the name and address on the log book are correct — and there is a financial reason as well as an administrative one. The vehicle tax refund is issued as a cheque to the name and address on the log book, so an old address means a cheque posted to somebody else's letterbox. Correct the record first, notify second.

The mechanics are that writing the vehicle off is treated like selling it to your insurance company. You keep the yellow section, send the rest of the log book to the insurer, and destroy the yellow section once you have finished with it. DVLA then cancels the vehicle tax and refunds any full months remaining, calculated from when it receives the information — which is the reason to notify the same day rather than a fortnight later. A Direct Debit is cancelled automatically. Part months, card fees and Direct Debit surcharges are not refunded.

Do not cancel the insurance policy the moment the car goes. That policy is what is paying the claim. Deal with the settlement first, then discuss the remainder of the policy term and moving cover to a replacement vehicle.

If you are keeping a Cat S or Cat N vehicle off the road while it is repaired, make a Statutory Off Road Notification rather than letting tax and insurance lapse silently, and remember a SORN vehicle cannot be kept or parked on a public road. Before it moves under its own power again you will need the replacement registration document, valid tax and an MOT.

The process is identical across England, Scotland and Wales, because vehicle registration and licensing are reserved to DVLA. Northern Ireland is the exception people assume exists and then get wrong in the other direction: driver licensing and vehicle testing there are run by the Driver and Vehicle Agency, but nidirect directs vehicle tax and registration queries — including SORN — to DVLA in Swansea. The insurance side is UK-wide throughout, because the FCA and the Financial Ombudsman Service cover all four nations.

Put the complaint in writing and make it a complaint, using the word. Set out what happened, what you say the car was worth, the evidence you rely on, and what you want the insurer to do. Attach the adverts, the purchase invoice, the service records and anything showing recent work. Ask for the engineer's report and the guide valuations if you have not already been given them. Keep every letter, email and call note — the Ombudsman asks for this material, and providing it up front makes a case move faster.

The insurer then has a clock. For most complaints a firm has eight weeks to consider it, and should send a final response before that runs out. If you do not receive a final response within the time limit, you can refer the complaint to the Financial Ombudsman Service without waiting. The final response must tell you the outcome and must mention your right to refer the matter to the Ombudsman.

There are two further limits worth knowing before you delay. You generally need to complain to the firm within six years of the problem, or within three years of becoming aware you had cause to complain — and once you have a final response, you have six months from the date on it to bring the complaint to the Ombudsman. Miss the six months and the Ombudsman usually cannot help, unless there were exceptional circumstances, the final response was not valid, or the firm consents.

You do not have to leave the money on the table while you argue. The Ombudsman's own guidance to insurers refers to firms making it clear to a customer that a payment can be taken without prejudicing the complaint, which is the mechanism to ask for by name: request written confirmation that accepting the undisputed amount now does not settle or withdraw your dispute about the valuation. Get that in writing before you accept anything, because the Ombudsman will look at whether you agreed to accept a payment.

The service is free and you do not need a representative — no lawyer, no claims management company — though a friend or family member can help you. Tell the Ombudsman if you are in financial difficulty, seriously ill or need help urgently, because that can affect how quickly a case is handled. Citizens Advice notes that a final decision is binding on your insurer; it is not binding on you unless you accept it, which leaves your legal rights intact if you do not.

The remedies are more generous than most people expect. If the Ombudsman decides the valuation was unfair it will normally tell the insurer to increase it, and to add 8% interest to the additional amount. Where a vehicle was scrapped without consent it looks at the effect on you and can require compensation for distress and inconvenience as well as for possessions lost inside the car. If the firm's conduct is the wider problem rather than your individual claim, the FCA's consumer helpline on 0800 111 6768 is the route for telling the regulator, though the FCA does not settle individual complaints.
