Do you have to declare a write-off when selling a car?
Selling a Cat S or Cat N car and not sure of your legal obligations? Here is what you must disclose, and what happens if you do not.
SELLING · 3 min read
The short answer
Yes, in practice. If you sell as a trader, leaving a write-off marker out is a misleading omission under the Digital Markets, Competition and Consumers Act 2024. A private seller must describe the car accurately and answer questions truthfully, and a Cat S car's category is printed on its logbook anyway. Describing it as clean, or denying the marker when asked, is misrepresentation and can leave you liable to refund the buyer and pay damages.
Why hiding it never works
Write-off markers show up on any decent history check, which most buyers now run for a few pounds. If a buyer discovers the marker after purchase and you did not disclose it, they have a strong claim against you for misrepresentation, and if you sold as a trader, under the Consumer Rights Act as well. It is not worth the risk.
How to disclose it properly
State the category clearly in the advert, for example repaired Cat N, and mention it again in writing before money changes hands. Keep proof of what you told them. Honest disclosure attracts the right buyers who understand salvage and filters out those who would complain later.

Disclosure actually helps your sale
Buyers of repaired salvage expect the marker. What builds trust is a folder of evidence: pre-repair photos, parts invoices and an MOT. A well-documented Cat N sells faster and for more than a vague one, because you remove the buyer's fear of hidden problems.
The bottom line
Always declare. Price it fairly against clean equivalents, back it with evidence, and you turn a legal obligation into a selling point.
