What is a Cat N Check?

A Cat N check (Category N) identifies vehicles that insurers have written off due to non-structural damage. While the chassis remains intact, Cat N markers often hide serious issues like electrical faults, engine damage, or flood immersion. Our comprehensive report pulls data directly from the MIAFTR database to protect you from bad investments.

Why Category N is Often Misunderstood

Sellers often claim Cat N damage was 'just a light scuff' or 'minor cosmetic work.' In reality, insurance companies only write off a vehicle when repair costs are uneconomical. A professional Cat N lookup ensures you aren't being misled about the severity of previous damage.

Stories From People Just Like You

Good site and very helpful. I found what I needed and will recommend the site to friends.

Very good and easy too use as a company

Car Owl gave an instant report to me flagging an issue with the car I was about to buy. This helped me take the right decision.

Gave me all the information I needed in one place.

Easy to use service that presented data in a clear and easy to consume way. Would happily use again and recommend to others.

Great service for instant and clear reports on a car with way more details than expected. Definitely recommended.

A clear and precise report.

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

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.

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

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

Good site and very helpful. I found what I needed and will recommend the site to my friends and colleagues.

Professional & faultless service. Does exactly what it says on the tin. Would definitely recommend anyone to use Car Owl services!

Very good very quick and on the ball report

Motorcycle vin with only 7 characters was causing issues with background checks and correct registration. This was the only company that provided the correct information. Recommended

Got all the information on my car. for a good price

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

First rate (indeed- unbelievable- instant) response to emails. Brilliant Customer Service- RATE for this day and era. Their Customer Service demonstrates that Big Firms CAN have a personal relationship with their Inquirers. Brilliant Customer Service. Simply outstanding. Ad multos annos to all at Car Owl.

Really worth paying for this detailed background check. Gave me sufficient information to make a better informed decision and after the checks were done we decided not to buy the vehicle. Money well spent!

Really pleased with the app. Actually found some information that I have been trying to find for a while.

Very good service

Good found out what I needed

Cat N Check: Frequently Asked Questions

Category N (formerly Cat D) is a common marker in the used car market. Here is what you need to know before signing the logbook.

What is the difference between Cat N and Cat S?

Cat S (Structural) means the car's frame or chassis was damaged. Cat N (Non-structural) means the damage did not affect the structural integrity of the vehicle. However, Cat N can still involve expensive repairs to the engine, electrics, or safety features.

Does a Cat N marker affect my insurance?

Yes. While most insurers will cover a Cat N car, some may charge higher premiums or require a fresh MOT to prove roadworthiness. Always perform a Cat N check so you can disclose the status to your insurer accurately.

Can I remove a Cat N marker from a car?

No. Once an insurance company has recorded a vehicle as a Category N write-off on the MIAFTR register, the marker is permanent and will stay with the vehicle's history forever.

Expert FAQ: Category N Write-offs

What is a Cat N check?

A Cat N check is a search of insurance databases to see if a vehicle has been written off as Category N (Non-structural). This means the car sustained damage that didn't affect the frame or chassis but was too expensive for an insurer to fix.

Is it safe to buy a Cat N car?

Cat N cars can be safe if repaired properly, but they often involve complex issues like electrical faults or suspension damage. A Cat N check helps you identify the vehicle's history so you can perform a targeted mechanical inspection.

Does a Cat N check include photos?

While our Cat N check provides the official insurance category and write-off date from the MIAFTR register, it does not include salvage auction photos. It focuses on providing verified legal and insurance status.

What was Cat N called before?

Before 2017, Category N was known as Category D. Both refer to non-structural write-offs where the repair costs were significant compared to the vehicle's value.

Will a Cat N car have a lower resale value?

Yes, typically a Cat N car is worth 20% to 30% less than a car with a clean history. Checking the status ensures you pay a fair price.
