If your insurer writes the car off: total loss categories and what follows

What being written off actually means

A write-off is a claims decision, not a mechanical verdict: GOV.UK says the insurance company decides whether the vehicle should be written off and then pays the current value of the vehicle instead of the cost of repairing it. Sources: ^[1]

The Financial Ombudsman Service says insurers sometimes call a write-off a total loss, and that a vehicle might be written off because it is not worth the cost of repairing it or because it has been stolen and never found. Sources: ^[10]

The amount normally in issue is market value, which the Financial Ombudsman Service describes as what the vehicle would have been worth just before it was stolen or damaged. Sources: ^[10]

When your vehicle is written off, your insurance company pays you the current value of the vehicle, instead of the cost of repairing it.

Your insurance company will decide if the vehicle should be written off or not.

What to do

• Ask the insurer for the engineer's report and the figures behind the decision before you accept anything.
• Ask which category has been applied, in writing, and ask when it will be reported.

Who sets the category, and under what authority

The categories come from the ABI Code of Practice for the Categorisation of Motorised Vehicle Salvage, which requires all motorised vehicle salvage to be categorised as A (Scrap / Recycle), B (Break), S (Repairable Structural) or N (Repairable Non-Structural). Sources: ^[6]

The code says the category must be applied by an Appropriately Qualified Person, defined as someone with a comprehensive technical education and training record relevant to motorised vehicle repair who holds a current competency-based assessment on salvage categorisation from the Institute of Automotive Engineer Assessors or an equivalent industry recognised body. Sources: ^[6]

An ABI news release describes the Salvage Code of Practice as a voluntary code that gives insurers and salvage firms guidance on categorising written-off vehicles; the code itself says it was produced and supported by the ABI and sets out ABI best practice. Sources: ^{[7] [6]}

The code has been revised repeatedly, with version 10 finalised in September 2017, version 11 in November 2019 and version 12 in 2025, and the stakeholders undertake to review the criteria every two years. Sources: ^[6]

The Salvage Code of Practice is a voluntary code

What each category means for repair and for road use

GOV.UK sets out four categories and says what you do next depends on which category the vehicle is in. Sources: ^[1]

Category A cannot be repaired and the entire vehicle has to be crushed; the ABI code adds that the whole vehicle is crushed following depollution and the removal of any recyclable components. Sources: ^{[1] [6]}

Category B cannot be repaired and the body shell has to be crushed, although other parts can be salvaged from it; the ABI code puts this as the structural framework being beyond repair while suitable parts can be reused. Sources: ^{[1] [6]}

Category S is a repairable vehicle that has sustained damage to some part of the structural frame or chassis, and GOV.UK says you can use the vehicle again if it is repaired to a roadworthy condition. Sources: ^{[1] [6]}

Category N is a repairable vehicle that has not sustained damage to the structural framework or chassis, and GOV.UK again says you can use the vehicle again if it is repaired to a roadworthy condition. Sources: ^{[1] [6]}

Category N does not mean the damage is cosmetic: the ABI code warns that although the damage has been noted as non-structural, there may still be some safety critical items that require replacement. Sources: ^[6]

A vehicle cannot be pushed into a repairable category by planning to use second-hand structure: the ABI code says vehicles should never be categorised as repairable on the basis that second-hand body structures, structural elements or frames will be used, and that the category should then always be Category B. Sources: ^[6]

For electric and hybrid vehicles the code treats a damaged structural high-voltage battery as making the vehicle Category S, because in some designs the battery forms part of the structural frame. Sources: ^[6]

A | Cannot be repaired | Entire vehicle has to be crushed

B | Cannot be repaired | Body shell has to be crushed, but you can salvage other parts from it

N | Can be repaired following non-structural damage | You can use the vehicle again if it’s repaired to a roadworthy condition

S | Can be repaired following structural damage | You can use the vehicle again if it’s repaired to a roadworthy condition

Whilst the damage to the vehicle has been noted as non-structural, there may still be some safety critical items that require replacement.

Where the decision is recorded and how long it follows the vehicle

The ABI's voluntary code says a MIAFTR entry, the Motor Insurance Anti-Fraud Theft Register, must be completed for every categorised vehicle, indicating the salvage category as soon as reasonably practical after the inspection, with amended or updated information submitted within two working days of the final decision. Sources: ^[6]

The ABI code says that completing a MIAFTR entry meets the regulatory requirements for insurers or self-insured organisations to notify DVLA. The legislation it cites does not itself name MIAFTR: Schedule 3A paragraph 1(1)(a) of the Road Vehicles (Registration and Licensing) Regulations 2002, substituted by regulation 8(a) of the 2018 Amendment Regulations, requires an insurer to notify the Secretary of State whether the vehicle is suitable for repair and, for notifications made on or after 20 February 2018, if it is suitable, whether it sustained structural damage. This guide does not determine whether a particular MIAFTR entry satisfies that statutory duty. Sources: ^{[6] [5]}

The ABI code says MIAFTR notifications are passed to vehicle data agencies, which use the information to provide a vehicle check service to the motor trade and the public, so a category is visible to future buyers through commercial history checks. Sources: ^[6]

The code says MIAFTR data should not be modified or removed other than to correct errors, and that re-categorisation may only take place in exceptional circumstances. Sources: ^[6]

For a Category A or B vehicle the code requires the MIAFTR entry to ensure the V5C is never reissued, and says that where the V5C is in your possession it must be securely destroyed. Sources: ^[6]

The record has a lasting effect on value: the Financial Ombudsman Service says vehicles that have been previously written off can put off potential buyers no matter how well they have been repaired, that this can affect market value, and that insurers are likely to lower the valuation as a result. Sources: ^[10]

If you later insure a repaired write-off and it is written off again, the Financial Ombudsman Service says a deduction may be fair where you knew or should have known you were buying a repaired write-off, but it is likely to require full market value where it was reasonable for you to be unaware of the history. Sources: ^[10]

All notifications to MIAFTR whether indicating theft or damage are passed to vehicle data agencies for a finance check. The data agencies use the information to provide a vehicle check service to the motor trade and the public.

Vehicles that have been previously written off can put off potential buyers, no matter how well they’ve been repaired. This can affect the market value of the vehicle, so insurers are likely to lower the valuation.

Buying the vehicle back and what you must do afterwards

GOV.UK says that if you want to keep a vehicle in category N or S, the insurance company will give you an insurance payout and sell the vehicle back to you; it does not offer the same route for category A or B. Sources: ^[1]

To keep a category S vehicle, GOV.UK says you must send the complete log book to your insurance company and apply for a free duplicate log book using form V62, and that DVLA will record the vehicle's category in the log book. Sources: ^{[1] [3]}

GOV.UK says you can keep the log book if you want to keep a category N vehicle. Sources: ^[1]

Whichever repairable category applies, GOV.UK conditions road use on the vehicle being repaired to a roadworthy condition; the payout and the buy-back do not by themselves make the vehicle legal to drive. Sources: ^[1]

The Financial Ombudsman Service says that when a vehicle is written off the insurer usually owns the salvage once the owner has accepted payment for the full market value, so the moment you accept the settlement matters if you want to keep the vehicle. Sources: ^[10]

The Financial Ombudsman Service says it does not think it is fair for an insurer to scrap your vehicle without telling you, and it will check whether you agreed to accept a payment and whether you told the insurer you wanted to keep the salvage. Sources: ^[10]

Where an insurer pays market value but returns the damaged vehicle less a salvage deduction, the Financial Ombudsman Service normally treats a deduction as fair but asks the insurer for evidence of how much it would have got for the salvage. Sources: ^[10]

If you want to keep a vehicle in category N or S, the insurance company will give you an insurance payout and sell the vehicle back to you.

DVLA will record the vehicle’s category in the log book.

When a vehicle is written off, the insurer usually owns the salvage once the owner has accepted payment for the full market value. But we don’t think it’s fair for your insurer to scrap your vehicle without telling you.

Checklist

• Say in writing that you want to retain the salvage before you accept any settlement figure.
• Get the salvage deduction itemised and ask for the evidence behind it.
• Retrieve personal belongings from the vehicle before it leaves the insurer's storage.
• For a category S buy-back, send the complete log book to the insurer and apply for the duplicate using form V62.
• Have the repair specified and inspected against manufacturer methods before the vehicle is used on the road.

The DVLA side: log book, registration number and vehicle tax

GOV.UK says you must tell DVLA your vehicle has been written off, and that you can be fined £1,000 if you do not. Sources: ^[1]

GOV.UK says to send the vehicle log book (V5C) to your insurance company but to keep the yellow sell, transfer or part-exchange your vehicle to the motor trade section from it. Sources: ^[1]

If you want to keep a private registration number, GOV.UK says to apply to take the registration number off the vehicle before the rest of the process; taking a private number off produces a V778 retention document proving you still have the right to use the number. Sources: ^{[1] [4]}

GOV.UK lists a vehicle being written off by your insurance company as one of the ways vehicle tax is cancelled, and says there is no other way to cancel vehicle tax. Sources: ^[2]

GOV.UK says you will automatically get a refund cheque for any full months left on your vehicle tax, calculated from the date DVLA gets your information, and that a Direct Debit will be cancelled automatically. Sources: ^[2]

GOV.UK says the refund cheque is sent to the name and address on the vehicle log book, and to contact DVLA if it has not arrived after 8 weeks. Sources: ^[2]

If you buy the salvage back and keep the vehicle off the road while it is repaired, the off-road route is a Statutory Off Road Notification (SORN), which GOV.UK lists alongside a write-off as a separate way of cancelling vehicle tax. Sources: ^[2]

You can be fined £1,000 if you do not tell DVLA.

You’ll automatically get a refund cheque for any full months left on your vehicle tax. The refund is calculated from the date DVLA gets your information.

What to do

• Deal with the private registration number first; once the vehicle has gone to the insurer or a salvage agent it is harder to unpick.
• Do not assume the insurer has told DVLA on your behalf. Confirm it, because the fine attaches to the registered keeper.
• SORN, and the point at which a retained vehicle must be taxed again before use, is covered separately; follow the official SORN route rather than guessing.

If you disagree with the valuation or the category

The Financial Ombudsman Service sees complaints that an insurer has not paid a fair price for the vehicle and complaints that an insurer has written the vehicle off without telling the owner first. Sources: ^[10]

It assesses whether a valuation is fair using specialist motor valuation guides and any other evidence provided, and it says it now typically considers adverts when assessing market value. Sources: ^[10]

If it thinks the valuation is unfair, it will tell the insurer to adjust it to either the highest figure in the guides or to the valuation supported by the other evidence, whichever is fairest in the circumstances. Sources: ^[10]

It will look at engineers' reports where an insurer says the vehicle was not in good condition, and says it would probably disagree with a lower valuation where the engineer has given no specific reasons or has relied on wear and tear expected in a car of that age. Sources: ^[10]

Under an agreed-value policy it expects the insurer to pay the amount agreed in the policy rather than a guide-based market value. Sources: ^[10]

You must complain to the insurer first. For most complaints, FCA DISP 1.6 requires the insurer to send either a final response or a written explanation by the end of eight weeks; the Financial Ombudsman Service says you can refer the complaint once you have a final response, or after eight weeks without one. Sources: ^{[8] [9] [12]}

FCA DISP 2.8 usually prevents the Financial Ombudsman Service from considering a complaint referred more than six months after the date on which the insurer sent a qualifying final response. The response must explain the six-month limit; exceptional circumstances or the insurer's consent can permit a late referral. Sources: ^{[9] [11]}

FOS consumer guidance summarises the deadline in simpler language, but the FCA Handbook rule controls the legal trigger: use the date the insurer sent the qualifying final response and keep evidence of sending. Sources: ^{[9] [11]}

FCA DISP 2.8 also normally prevents the Ombudsman from considering a complaint referred more than six years after the event complained of or, if later, more than three years after you became aware, or ought reasonably to have become aware, that you had cause to complain. Sources: ^{[9] [11]}

The six-year/three-year branch has a separate preservation rule: FCA DISP 2.8 says that branch does not exclude a complaint if you referred it to the insurer (the respondent) or the Ombudsman within the applicable period and have a written acknowledgement or another record that it was received. The six-month clock after a qualifying final response remains a separate rule. Sources: ^[9]

The Financial Ombudsman Service says its service is free, that you do not need to pay anyone such as a lawyer or claims management company to represent you, and that if it finds the business treated you unfairly it will tell them to put you back where you would be if they had not made a mistake, and may award for distress and inconvenience. Sources: ^{[12] [13]}

Disagreement specifically about the category letter, rather than the money, is dealt with inside the industry code first: the ABI code says a dispute about categorisation should be escalated to an Appropriately Qualified Person who assumes responsibility for the final decision. Sources: ^[6]

If we think the valuation is unfair, we’ll tell your insurer to adjust it to either the highest in the guides or to be in line with the valuation supported by the other evidence – whichever is the fairest in the circumstances.

more than six months after the date on which the respondent sent the complainant its final response

In the event of a dispute between the insurer/self-insured and other interested parties regarding categorisation, the matter should be escalated to an AQP who assumes responsibility for the final decision.

Checklist

• Complain to the insurer in writing and ask it to issue a qualifying final response.
• Gather the valuation evidence the ombudsman actually uses: guide valuations, close-specification adverts, service history, mileage and any independent engineer's report.
• Keep the engineer's report the insurer relied on, and challenge any condition or pre-existing damage deduction that is not given specific reasons.
• Record the date the insurer sent the qualifying final response and keep the envelope, email headers or other evidence of sending. FCA DISP 2.8 normally measures the six-month period from that sending date; note the stated deadline too and refer promptly if there is any discrepancy.
• If the argument is about the category letter rather than the payout, ask the insurer to escalate it to an Appropriately Qualified Person and to say who that person is.

Why this is not the same as a dispute with a garage

The complaint here is against your insurer about how it handled the claim and settlement, not against the garage that quoted for or carried out the repair. Sources: ^{[13] [10]}

The remedy route is different too: the Financial Ombudsman Service takes complaints about financial businesses after the business's own complaints process, and it says it weighs the relevant law, any regulations that applied at the time and any industry codes of conduct that were in force at the time. Sources: ^{[13] [12]}

A complaint about the standard of workmanship on a repair the insurer arranged is a different type of complaint from a valuation or write-off complaint, and the Financial Ombudsman Service lists vehicle repairs separately from motor valuations and write-offs. Sources: ^[13]

If your argument is that a garage did the work badly, charged too much or took too long, that is a consumer services claim against the garage and it follows the repair-dispute route: complain to the garage in writing, then alternative dispute resolution, then court.

If your argument is that the insurer valued the vehicle too low, categorised it wrongly, scrapped it without telling you or refused to sell the salvage back, that is an insurance complaint and it follows the route on this page.

The two can overlap. A repair that was botched before the accident, or an inspection report you commissioned yourself, can be evidence in an insurance complaint even though the garage is not the respondent.

Important

Do not drive a vehicle that has been declared a total loss on the assumption that a repairable category makes it legal. GOV.UK conditions further use on the vehicle being repaired to a roadworthy condition.

Nothing here values your vehicle or predicts what an insurer or the ombudsman will decide.
