Has this car been in an accident? The honest answer, and what you can actually check

Plenty of sites will sell you an "accident history check". None of them can tell you whether a car's been in an accident, because there's no accident database a buyer can search. What exists is a register of cars the insurers wrote off. That's useful, but it's a much narrower thing than the name on the button, and knowing the difference is most of what protects you.

Can you check if a car has been in an accident?

Not directly. There's no public record of accidents or accident repairs in the UK that a buyer can look up by registration. Insurers do share claims data with each other, through a database run by the Motor Insurers' Bureau, but MIB says only organisations that share claims data can access it, so it isn't something you or any car-check site can search on your behalf.

What you can check is narrower:

So the honest answer to "has this car been in an accident" comes from three places: the write-off register, the MOT record and the car itself. Each catches something the others miss.

How do you check if a car has been written off?

With a provenance check, often called an HPI check. When an insurer decides not to repair a damaged car, the insurance industry's code of practice says it must be categorised, A, B, S or N, and recorded on the industry's write-off register, which MIB now calls Vehicle Salvage and Theft Data. That register is passed to the vehicle data companies, and it's what every paid check reads.

A write-off can show up on the log book too, but not reliably. Under the ABI code, a Cat S car's V5C is reissued with a note of its status and a Cat N car's is reissued with no comment, so a clean V5C doesn't rule a write-off out. Cat N and Cat S explained covers what each category means and how much less you should pay.

What doesn't the write-off register catch?

Every accident where the insurer decided to repair the car rather than write it off. The ABI code only categorises vehicles where the insurer has decided not to repair, and says vehicles with no or minimal damage can sit outside it altogether. So a car that had a bumper, wing and headlamp repair paid for by an insurer is, as far as any check is concerned, a car that's never been in an accident.

Add the repairs nobody claimed for, the owner who paid cash to avoid losing their no-claims bonus, and the dealer who bought a damaged car cheaply and fixed it, and it's clear the register only ever sees the cars an insurer chose not to fix. That's not a criticism of it. It's a register of write-offs, and it does that job. It just isn't an accident history, whatever the check calls itself. What an HPI check won't tell you goes through the rest of what records can't see.

What can the MOT history tell you about accident damage?

More than people expect, for free. The GOV.UK MOT history lists every failure and advisory since 2005, and accident damage leaves tracks in it:

• Structural failures or advisories on the body, sills or floor, especially on a young car that shouldn't have any corrosion yet.
• Suspension and steering items on one side only, like a bent track rod, a damaged wishbone or a wheel misalignment noted on one corner.
• Lights and lamps replaced or failing on one corner, or a windscreen damage note, in the same test as other front-end items.
• A long gap in testing followed by a car that reappears looking fine, which can be a car that was off the road being repaired.

None of those proves an accident. Each is a reason to look closely at that corner of the car and to ask the seller a direct question. MOT advisories explained shows how to read the record as a sequence.

What are the physical signs a car has been in an accident?

At the viewing, in daylight and in the dry, look for repair rather than damage. Damage gets fixed; repairs leave traces:

• Panel gaps that differ from one side of the car to the other, or a bonnet or boot lid that doesn't sit evenly.
• Paint that doesn't quite match from one panel to the next, orange-peel texture, overspray on rubber seals, trim or glass.
• Bolts on the wings, bonnet hinges or door hinges with the paint cracked off them, which means the panel's been removed.
• New parts on an old car: one headlamp clearer than the other, a newer-looking radiator or bonnet catch, mismatched glass markings.
• Underneath and in the boot: creases or fresh sealant in the boot floor, the spare wheel well and the chassis legs.
• On the drive: a car that pulls to one side, a steering wheel that isn't straight, or tyres worn unevenly on one corner.

If you can't judge it, that's what an independent inspection is for; is a car inspection worth it compares what the AA, the RAC and the independents check and what they charge.

Does the advert give it away?

Often. Sellers of repaired cars rarely lie outright, they just choose words carefully. "Minor cosmetic marks", "small repair to rear", "paintwork not perfect" and "priced to reflect" can all be innocent, and they can all be the only mention you'll get of a repair. A recent respray or new headlamps mentioned in passing on a young car is worth a question. So are photos that only show one side of the car, or are taken from far away in poor light.

The question that works is a specific one: "Has it ever had any bodywork or paintwork done, and do you have the invoice?" A seller who knows about a repair and has the paperwork will say so, and a repair done properly with an invoice is nothing to worry about. A seller who says "not that I know of" on a car with mismatched paint has told you something.

Is it worth buying a car that's been in an accident?

A properly repaired one, yes, and often at a discount. What matters is the quality of the repair and whether it's declared. A declared Cat N with a good repair and the invoices is a known quantity. An undeclared structural repair done cheaply is the opposite, and you can't see the quality of a structural repair from the outside, which is why structural damage is where an inspection earns its fee.

Which of these can a check actually close?

Start with the concession, in full: no check, ours included, can tell you whether a car's been in an accident. The accident data that exists belongs to insurers and isn't sold to buyers, and the repairs nobody claimed for aren't recorded anywhere. On write-offs, our data is the same data everyone sells: it comes from the insurance industry's register through a data supplier, and so does every other provider's. Anyone implying they hold a complete accident history is describing a write-off check.

What we can do is close the two parts of the question that are on record, and read the third.

The Provenance Check runs the write-off register, along with outstanding finance and the police theft register, and where a write-off went through a salvage auction it shows the auction photos where they're available, which is the nearest thing to seeing the damage itself. A Cat A or B forces the report to its highest risk rating outright; a Cat S or N holds the verdict at caution, and pushes it to high risk when the advert hides it. It includes the full Smart Check too: known faults with repair costs, the questions to ask and a negotiation figure.

The free scan does the MOT half and the advert half. It reads the full DVSA history as a sequence, with long testing gaps and idle stretches marked and every failure and advisory in front of you, and it reads the seller's wording, so "never been in an accident" or "no accidents" sits next to whatever the record shows. It also checks the car against the known faults for that model, so you can tell a suspension advisory that's a documented weakness, as on our Ford Focus and Vauxhall Astra pages, from one that's worth asking about. On a Provenance report, a write-off the advert doesn't mention becomes a headline finding.

What remains is the car itself. A repair nobody claimed for and that the MOT never noticed is invisible to every database there is. That's the gap your own eyes, or an inspector's, have to close.

So what should you actually do?

Run the advert and the registration through the free scan before you view. It reads the MOT record and the seller's words together and tells you where to look on the car. If it's worth pursuing, upgrade the same report to a Provenance Check for the write-off, finance and theft records, then do the walk-round above in daylight. The upgrade runs on the same link with nothing re-run, so starting free costs you nothing if the first answer is walk away.
