App StoreA write-off check helps buyers understand whether a vehicle has been recorded by an insurer after accident, theft, fire, flood or other damage. Some write-offs should never return to the road, while others may be repaired and sold legally.
The key is transparency. A repaired write-off may be cheaper, but it can affect safety, resale value, insurance and finance. You should know about it before buying, not after.
UK write-off categories
Category A vehicles are usually scrap only and should not return to the road. Category B vehicles have a body shell that should be crushed, although some parts may be salvaged. Category S means structural damage was recorded, and Category N means non-structural damage was recorded.
Older records may use previous category names. If a seller mentions Cat C or Cat D, ask for more detail and repair evidence.
Why buyers should care
Write-off history can affect safety and value. Structural damage may have been repaired well, poorly or not fully documented. Non-structural damage can still be expensive and may involve electronics, trim, suspension or other components.
Insurance can also be affected. Some insurers may ask about write-off history, and future buyers may value the vehicle lower.
How to use a write-off result
If a check shows write-off history, ask for repair invoices, photographs, inspection evidence and a clear explanation. Consider a professional inspection, especially for Category S vehicles.
If the seller did not disclose the write-off marker, be cautious. A transparent seller should be willing to discuss the history and price the car accordingly.
Price, safety and future resale
A write-off marker can follow the car for the rest of its life. Even when the vehicle has been repaired well, future buyers may be more cautious and insurers may ask additional questions. That can affect what the car is worth today and what it may be worth when you sell it.
For that reason, write-off history should be reflected in the price and supported by clear repair evidence. If the car is expensive, performance-focused or structurally damaged, independent inspection is a sensible step before buying.
Ask who repaired the vehicle, what parts were replaced and whether alignment, airbags, sensors or safety systems were checked. Cosmetic repairs can look convincing in photographs, but a written repair history and inspection report give you stronger evidence than appearance alone.
If you plan to finance or insure the vehicle, check the position before committing. Some providers may treat previously written-off cars differently, and discovering that after payment can make ownership more complicated than expected.
When in doubt, compare the car against similar non-written-off examples so you can judge whether the discount is enough for the added risk.
