What is a Cat S Check?

A Cat S check identifies vehicles that have been written off due to structural damage. Unlike Category N, a Cat S vehicle has suffered damage to its 'skeleton'—the chassis or crumple zones. For complete peace of mind, our comprehensive history report includes insurance write-off details, salvage records, and high-resolution damage photos where available.

Structural Integrity

Find out if the vehicle's frame, chassis, or structural pillars were compromised in a major accident.

Write-off Records

We query the MIAFTR database to confirm if an insurer declared the car a Category S total loss.

Resale Value Impact

A Cat S marker can reduce a car's value by 30-50%. Ensure you aren't paying full market price for a write-off.

Safety & Roadworthiness

Structural repairs must be professional. Our check helps you decide if a car is safe for you and your family.

Why a Cat S Check is Essential

A Category S vehicle is one that an insurance company decided was too expensive to repair structurally. While these cars can return to the road, buying one without knowing its history is a massive financial and safety risk.

Identify Hidden Damage

Sellers often hide a car's 'S' status. Our report brings the truth to light using official insurance data.

Negotiate Better

If you choose to buy a Cat S car, use our report to negotiate a price that reflects its true history.

Salvage History

See where the damage occurred and whether the vehicle was sold through a salvage auction like Copart.

Ed Wheeler

My second time using car owl , and certainly didn’t disappoint, they guys really do take out all the hard work, great effective services highly recommend

Jonathan Barratt

Brilliant tool that helped me feel confident about buying a used car. I was able to check out the history of the vehicle before seeing it, to ensure I knew the info given was correct, and check it had no hidden issues. The fact that the check goes deep enough to show previous number plates that have been on a vehicle and at what time etc just shows the quality. Once I was with the car and happy I wanted to proceed, I was able to enter the vin number onto the report and it confirmed that it was in fact the correct car. Hoping not to buy a car any time soon but will definitely use again when I do.

Stan

Found a car I really liked online and was about to put down a deposit, but thought I’d run a quick Car Owl check first just to be sure. Turned out the mileage had been tampered with and it had failed multiple inspections in the past. The ad made it look spotless. Honestly can’t believe how much info the report showed. Would’ve never known otherwise. Car Owl probably saved me thousands. Honestly, don’t skip it

Dan W

Revealed the car was still on finance. Without Car Owl I would have been stuck paying off someone else's loan. Highly recommend

I used this to find the registration for a project car that I bought with no documentation so I could send off a v62… old vin so most places couldn’t help. But this came straight back with all of the relevant information 👌

Stopped be buying a potential stolen vehicle. So well worth the cost of getting it checked

Cat S vs Cat N: What You Need to Know

Understanding the severity of a 'Cat S' marker is vital for any used car buyer. It is significantly more serious than a non-structural Cat N marker.

Is it legal to drive a Cat S car?

Yes, it is legal to drive a Cat S car on UK roads once it has been repaired and the DVLA has been notified. However, you must ensure the repairs were carried out to a professional standard, as the structural integrity was once compromised.

Does a Cat S check show photos of the damage?

Our premium Cat S reports often include salvage auction photos. This allows you to see the actual extent of the structural damage before it was repaired, giving you a better idea of the car's 'before' state.

Will Cat S affect my insurance premiums?

Most insurance companies will cover a Cat S vehicle, but your premiums may be higher. Some niche insurers may refuse cover entirely. Always run a Cat S check before buying to get an insurance quote first.

Frequently Asked Questions about Cat S Checks

What does Cat S stand for?

Cat S stands for 'Category S' (Structural). It is a category of insurance write-off where the vehicle has sustained structural damage but is deemed repairable.

How do I know if a car is Cat S?

The most reliable way is to perform a Cat S check using the vehicle's registration. This queries insurance databases that record every structural write-off in the UK.

Is Cat S worse than Cat N?

Yes. Cat S involves structural damage (chassis, pillars, etc.), whereas Cat N is non-structural (cosmetic or electrical). Structural damage is more expensive and difficult to repair correctly.

Can a Cat S car be put back on the road?

Yes, if it is repaired to a professional standard. However, the Cat S marker will remain on the vehicle's record for life.

Does a Cat S check provide photos of the vehicle damage?

While our Cat S check does not include salvage auction photos, it provides the most critical information: the official insurance write-off category and the date it was recorded. This data is pulled directly from the MIAFTR (Motor Insurance Anti-Fraud and Theft Register) to confirm the vehicle has been legally classified as having structural damage.
