Car Write Off Check
Enter a UK registration to instantly reveal whether a vehicle has been declared an insurance write-off and which damage category it carries.
What Is Included in a Car Write Off Check?
562,185 vehicles were written off in the UK in 2024 — roughly one every minute. Many are repaired, relisted and sold without full disclosure. Our write off check searches the MIAFTR database and insurance records to give you the complete picture before you buy.
- Make and model confirmation: Verifies the vehicle identity matches the details provided by the seller.
- Write-off category: The insurance category assigned — Cat A, Cat B, Cat S or Cat N — and what it means for roadworthiness and legality.
- Insurer name: The insurance company that declared the vehicle a total loss.
- Cause of damage: The nature of the incident that led to the write-off, such as accident, fire, flood or theft recovery.
- Loss date: The date the vehicle was declared a write-off, allowing you to cross-reference with mileage and ownership history.
- Theft indicator: Whether the vehicle was reported as stolen in connection with the write-off event.
- Damage location: The area of the vehicle that sustained damage, such as front, rear or offside, where available.
- Damage chart: A visual representation of the damage location where data is available from insurer records.
Write-off data is sourced from the Motor Insurance Anti-Fraud and Theft Register (MIAFTR), the industry-standard database used by UK insurers to record total loss declarations. A write-off category is permanent — it stays on the vehicle's record for life, affecting resale value, insurance costs and financing options for every future owner.
Frequently Asked Questions
What is a write-off check?
A write-off check searches the Motor Insurance Anti-Fraud and Theft Register (MIAFTR) and related insurance databases to reveal whether a vehicle has ever been declared a total loss by an insurer. It returns the write-off category assigned (A, B, S or N), the insurer involved, the cause of damage, the loss date and the damaged areas of the vehicle where recorded. In 2024 alone, 562,185 vehicles were written off in the UK — roughly one every minute — making this one of the most important checks to carry out before buying any used car.
What are the UK car write-off categories?
UK insurers use four write-off categories introduced by the Association of British Insurers in October 2017. Understanding which category applies to a car you are considering buying is essential, as they have very different implications for safety, legality and value.
- Category A (Scrap): The vehicle is so severely damaged it must be crushed entirely. No parts may be reused and the car can never return to the road under any circumstances. Never purchase a Cat A vehicle.
- Category B (Break): The vehicle cannot return to the road and the body shell must be destroyed, but some mechanical parts may be salvaged and reused. Never purchase a Cat B vehicle for road use.
- Category S (Structural): The vehicle has sustained structural damage to the chassis, crumple zones or body frame. It can be professionally repaired and returned to road use after re-inspection, but all repairs must be disclosed and the marker remains permanently on the vehicle's history.
- Category N (Non-Structural): The vehicle has non-structural damage such as cosmetic, electrical, braking or suspension issues. It can be repaired and driven again, but the write-off marker is permanent. Research by CarVeto suggests a Cat N write-off typically reduces resale value by 30 to 50 percent.
Only Category S and Category N vehicles can legally be purchased and put back on the road. Categories S and N replaced the old Categories C and D in October 2017, so older vehicles may still carry the previous classification.
Does a write-off show on V5C?
Yes. When an insurer declares a vehicle a total loss, they are required to notify the DVLA, who updates the vehicle record. The write-off status should appear on the V5C registration document. However, you should not rely on the V5C alone: not all write-offs are recorded promptly, there can be reporting delays, and the V5C does not show the specific damage details, the insurer involved or the cause of the write-off. A dedicated write-off check against the MIAFTR database provides considerably more comprehensive and reliable information than inspecting the V5C alone.
Is it safe to buy a Cat S or Cat N car?
Buying a Category S or Category N vehicle is legal and can represent good value if repairs were carried out to a professional standard using manufacturer-approved or Thatcham Research-approved methods. However, there are important factors every buyer must consider before proceeding. A write-off category is permanent and remains on the vehicle's record for life, affecting resale value — typically by 30 to 50 percent for Cat N vehicles — insurance premiums and the availability of financing. Some insurers charge higher premiums for previously written-off vehicles or decline to cover them at all. Before buying any Cat S or Cat N car, request proof of repair documentation, consider commissioning an independent pre-purchase inspection, and confirm with your insurer that they will provide cover before you commit.
Can I refuse my car being written off?
You can challenge an insurer's write-off decision if you believe the car's market value has been undervalued or that the repairs are more economical than estimated. Gather evidence including comparable used car listings from reputable platforms, service history records and independent garage repair quotes to support your position. Submit a written challenge to your insurer's valuation team. If they reject it, you can escalate to the Financial Ombudsman Service, which recorded a 38 percent rise in car and motorcycle insurance complaints in 2024, many concerning write-off settlement values. For Category S and Category N write-offs you may also have the option to buy back the vehicle from the insurer — typically at 10 to 30 percent of its pre-accident market value — and arrange repairs yourself before returning it to the road.
How do I check if a car is categorised as a write-off for free?
The DVLA's free online vehicle enquiry returns basic details such as MOT status and road tax but does not provide write-off category information. The MIAFTR database that holds insurance write-off records is not accessible through any free government service. A visual inspection can highlight indicators of previous repair work — mismatched paint, uneven panel gaps, welding marks or inconsistent surface texture — but it cannot confirm a write-off category, identify the insurer or provide the loss date. A paid write-off check via a vehicle history report is the only reliable way to access complete MIAFTR data including category, cause of damage, loss date and insurer name.
Why a Car Write Off Check Matters When Buying Used
Here is what a write off check protects you from when buying a second-hand vehicle:
- Buying a Cat A or Cat B vehicle unknowingly — these cars are illegal to drive and should never appear for sale, yet examples do reach the used car market.
- Overpaying for a Cat S or Cat N car — sellers are not legally required to disclose a write-off history in a private sale, and many do not. Without a check, you have no way of knowing the car's true market value.
- Hidden structural damage — a Cat S car with poor-quality repairs can have compromised crumple zones, a weakened chassis or misaligned body panels that are invisible to a standard visual inspection.
- Insurance complications — some insurers will not cover a previously written-off vehicle, or charge significantly higher premiums. Discovering this after purchase can leave you unable to use the car affordably.
- Reduced future resale value — a write-off marker is permanent. Even if the car looks and drives perfectly, the history will affect every future private sale and trade-in valuation.
A write off check takes seconds and gives you the verified MIAFTR data you need to decide whether to proceed, negotiate a lower price or walk away entirely.
Our write off check is part of a full vehicle history report that also covers outstanding finance, stolen markers, mileage anomalies, keeper history and vehicle valuation — everything you need to buy with confidence.
