How to Check If a Car Has Been in an Accident
Run a car damage check on the registration and then look at the car, because the two find different things. The check shows accidents that an insurer recorded as a write-off, with the category and date. It cannot show a crash that was repaired privately, and a great many are — which is why the physical tells matter as much as the report. Here’s what each half tells you, and what to do with a result.
What a car damage check shows, and what it doesn’t
A damage check queries the insurance industry’s write-off register. If an insurer ever assessed the car as uneconomic to repair, it’s there: the category (A, B, S or N), and the date. That is the whole of what’s on record, and it’s important to be clear about it. A car hit in a car park and repaired at a body shop for cash has no marker. A car repaired under an insurance claim that fell short of a total loss has no marker either. So a clear damage check means “never written off”, not “never damaged” — a distinction sellers are happy to let you blur.
Reading a write-off result
Category S is structural damage that has been repaired; Category N is non-structural — typically bodywork, electrics or a flood. Both can legally return to the road and both can be sound cars if the repair was competent. Both are also worth materially less than an unrecorded equivalent, harder to insure, and harder to sell on. Categories A and B are scrap-only and shouldn’t be for sale at all. If a check returns S or N and the seller didn’t mention it, that’s your answer about the seller before it’s an answer about the car. Our categories guide explains each letter in full.
The physical tells of a repaired accident
Look at the car in daylight, from the corners. Panel gaps: uneven gaps around a bonnet, boot or door mean a panel has been off or a chassis leg is not where it was. Paint: a slight colour or texture mismatch between panels, overspray on rubber seals or in the door shuts, and masking lines under the bonnet are all body-shop signatures. Glass: windscreens and lights should carry the same manufacturer marking as the rest of the car; one odd one out has been replaced. Underneath: fresh underseal in one area, new-looking welds, or a crumpled inner wing behind a straight outer one. Inside: airbag warning lights that stay on, or — worse — go off suspiciously quickly. Alignment: on the test drive, the steering wheel should be straight when the car is; a car that pulls or wears its tyres unevenly has been bent.
None of these proves an accident alone. Two or three together, on a car with a “clear” check, tell you the check wasn’t the whole story.
Undeclared repairs and what you can do
From a dealer, describing a repaired write-off as clean is a misdescription under consumer law, and you have a claim. From a private seller it’s harder: the car must be as described, but “no accidents” said in a driveway is difficult to prove later. The practical protection is the same as everywhere in this hub — check before you pay, not after, and get an independent inspection on any car where the tells and the price don’t agree.
When accident history is fine
Plenty of good cars have had a bump. A Cat N for a stolen-and-recovered car with cosmetic damage, repaired by a main dealer with invoices, priced accordingly, is an honest buy. A clean-check car with one resprayed door and a receipt is an honest buy. The problem car is the one where the story and the metal disagree, or where nobody mentioned it until you asked. Run a free car check for the history and the Premium check for the write-off record, then go and look at the corners.
Accident check FAQs
Can I check if a car has been in an accident for free? Not the write-off record — that comes from insurers and sits in the paid layer everywhere. The free check shows MOT advisories, which sometimes note accident-related items, and keeper history, which shows a car that changed hands right after a date that might matter.
Does a damage check show minor accidents? No. Only accidents that resulted in an insurer writing the car off. Minor and privately repaired damage leaves no record.
Is a Cat N car safe to buy? It can be. Ask for repair invoices and photos, get an inspection, and pay a Cat N price, not a clean-car price.
What if the check is clear but the car looks repaired? Trust the metal. A clear check rules out a recorded write-off; it doesn’t rule out a repair. Price it as a repaired car or walk.
