Cat N Check
What is a Cat N Car?
A Category N (Cat N) car is a vehicle that has been written off by an insurance company after being damaged, but the damage is not structural. Instead, the damage may affect non-structural parts such as the bodywork, suspension, electrical systems or interior.
Although the vehicle was declared a total loss by an insurer, it can usually be repaired, pass an MOT if required, and legally return to the road once it is safe to drive.
The decision to classify a vehicle as Category N is based on the cost of repairs compared with the vehicle's value, rather than the severity of the damage alone.
What does Category N mean?
Category N replaced the old Category D write-off classification in October 2017.
A Cat N vehicle has not suffered structural damage, but it may have required repairs to components such as:
- Body panels
- Doors
- Bumpers
- Lights
- Suspension components
- Steering components
- Electrical systems
- Interior trim
Because these repairs can still be expensive, insurers sometimes decide it is uneconomical to repair the vehicle, even if it could be safely repaired.
Can you buy a Cat N vehicle?
Yes. Many Cat N vehicles are repaired and sold back onto the used car market.
However, before buying one, it's important to check:
- Whether it has been recorded as a Category N write-off
- The vehicle's MOT history
- Previous mileage records
- Any outstanding finance
- Signs of repeated repairs or recurring advisories
A full VehicleScore check helps you understand the vehicle's history before you decide to buy.
How to Check if a Car is a Category N Write-Off
If you're buying a used car, carrying out a Cat N check is one of the most important steps before handing over your money. A vehicle may look to be in excellent condition, but if it has previously been declared a Category N insurance write-off, it could affect its value, insurance costs and future resale price.
Fortunately, checking a vehicle's history only takes a few moments.
Enter the Vehicle Registration
Simply enter the vehicle's registration number into the VehicleScore search box to generate a comprehensive vehicle history report.
Unlike basic registration lookups, VehicleScore combines information from multiple trusted data sources to give you a complete picture of the vehicle's past.
Review the Vehicle History Report
As shown in the example report, you'll receive far more than just a Cat N result. Your report includes a range of important vehicle checks, including:
- Category N insurance write-off records
- Category S insurance write-off records
- MOT history and advisory notices
- Mileage history
- Outstanding finance checks
- Road tax status
- Vehicle specifications
- VehicleScore rating and AI-powered insights
Looking at the vehicle's complete history helps you understand whether previous damage could affect its long-term reliability or value.
Make an Informed Buying Decision
A Category N vehicle isn't necessarily one to avoid. Many are professionally repaired and provide years of reliable motoring. However, it's important to understand exactly what you're buying before making a decision.
By checking a vehicle's write-off history alongside its MOT records, mileage history and other important information, you'll be in a much stronger position to negotiate with confidence and avoid unexpected surprises after purchase.
Should You Buy a Cat N Car?
Buying a Category N (Cat N) vehicle can be an excellent way to save money, but it's important to understand both the advantages and potential drawbacks before making a purchase.
A Cat N classification doesn't automatically mean a vehicle is unsafe or unreliable. Unlike a Category S vehicle, a Cat N car has not suffered structural damage. Instead, the insurer decided that repairing the vehicle wasn't economically worthwhile, even though it could often be repaired safely.
Many Category N vehicles return to the road after professional repairs and provide years of dependable motoring. However, as with any used car, it's essential to carry out proper checks before buying.
Advantages of Buying a Cat N Vehicle
A Cat N vehicle can offer several benefits, including:
- A lower purchase price than an equivalent non-write-off vehicle.
- Good value for buyers willing to accept a previous insurance write-off.
- Damage is non-structural, meaning the vehicle's chassis or structural frame has not been affected.
- Many vehicles are repaired to a high standard and continue to provide reliable service.
For buyers who have carried out thorough checks, a Cat N vehicle can represent excellent value for money.
Things to Consider Before Buying
Before purchasing a Category N vehicle, it's worth taking a little extra time to understand its history.
Consider checking:
- The reason the vehicle was classified as Cat N.
- Whether repairs appear to have been completed professionally.
- The vehicle's MOT history and advisory notices.
- Mileage records to ensure they are consistent.
- Whether there is any outstanding finance.
- The vehicle's overall condition during inspection.
Completing a full vehicle history check can help identify potential issues before they become expensive problems.
Our Recommendation
A Cat N vehicle shouldn't automatically be ruled out simply because it has previously been written off. Many are perfectly good cars that were uneconomical for an insurer to repair but have since been restored to a safe and roadworthy condition.
The key is understanding why the vehicle received its Category N classification and reviewing its complete history before making a decision. By checking insurance write-off records alongside MOT history, mileage, finance and other vehicle information, you'll be in a much stronger position to decide whether the car represents good value.
Cat N vs Cat S: What's the Difference?
Category N and Category S vehicles are both insurance write-offs, but they describe very different types of damage. Understanding the distinction can help you make a more informed decision when buying a used car.
The most important difference is whether the vehicle has suffered structural damage.
While both categories can legally return to the road after repairs, Category S vehicles have sustained damage to structural components such as the chassis or frame, whereas Category N vehicles have not.
Feature | Cat N | Cat S |
|---|---|---|
Structural damage | No | Yes |
Chassis/frame damaged | No | Yes |
Can return to the road | Yes | Yes |
Typical repairs | Panels, lights, bumpers, suspension, electrical | Chassis, frame, structural repairs |
Resale value | Usually reduced | Usually reduced further |
Recommended before buying | Full vehicle history check | Full vehicle history check |
Which Should You Buy?
Neither Category N nor Category S automatically means a vehicle is a bad purchase. Many examples of both have been professionally repaired and continue to provide years of reliable service.
However, because Category S vehicles have previously suffered structural damage, buyers should take extra care to assess the quality of repairs. A Category N vehicle is often considered the lower-risk option because the damage did not affect the vehicle's structural integrity.
Regardless of the category, always carry out a full vehicle history check before purchasing a used vehicle.

Frequently Asked Questions
What is a Cat N car?
A Cat N (Category N) car is a vehicle that has been written off by an insurance company because it was considered uneconomical to repair. Unlike a Category S vehicle, the damage is non-structural, meaning the vehicle's chassis or structural frame has not been damaged. Many Cat N vehicles are repaired and legally returned to the road.
Is Cat N the same as Category D?
No. Category N replaced the old Category D classification in 2017. Both categories describe vehicles with non-structural damage, but Category N uses the newer insurance write-off system introduced by the Association of British Insurers (ABI).
Is a Cat N car safe to drive?
A Cat N vehicle can be perfectly safe to drive if it has been repaired correctly and is roadworthy. The Category N classification simply means the damage was not structural. As with any used vehicle, it's important to inspect the car thoroughly and review its history before buying.
Can a Cat N car pass an MOT?
Yes. A Category N vehicle can pass an MOT provided it meets all legal roadworthiness requirements. Its Cat N status does not prevent it from being tested or legally driven on UK roads.
Does Cat N reduce a car's value?
Yes. A Category N vehicle is usually worth less than an equivalent vehicle with no insurance write-off history. The exact reduction depends on factors such as the age of the vehicle, the quality of repairs and market demand.
Can you insure a Cat N car?
Yes. Most insurers will insure Category N vehicles. However, some insurers may charge a higher premium or ask additional questions about previous damage and repairs.
Can I finance a Cat N vehicle?
Some lenders will provide finance for Category N vehicles, while others may have restrictions. Approval depends on the lender's policies, the vehicle's value and your personal circumstances.
Can a dealer sell a Cat N vehicle?
Yes. Dealers can legally sell Category N vehicles, provided they accurately disclose the vehicle's write-off history where required. Buyers should always carry out an independent vehicle history check before purchasing.
Can Cat N status be removed?
No. Once a vehicle has been classified as Category N, the record remains part of its history permanently. It cannot be removed simply because repairs have been completed.
How do I check if a vehicle is Cat N?
The easiest way is to carry out a vehicle history check using the vehicle's registration number. A comprehensive report will confirm whether the vehicle has ever been recorded as a Category N insurance write-off, along with other important history such as MOT records, mileage and finance.

A Category N vehicle can represent excellent value if it has been repaired to a high standard and is priced appropriately. Before buying, review its full history, inspect the quality of repairs and consider arranging an independent inspection if you have any concerns.
Does Cat N affect road tax?
No. A Category N classification has no direct effect on Vehicle Excise Duty (road tax). Road tax is calculated based on factors such as the vehicle's age, emissions and fuel type.
Does Cat N affect resale value?
Yes. Most Category N vehicles sell for less than similar vehicles without a write-off history. Buyers often expect a discount because the insurance write-off record remains with the vehicle permanently.
Why should I carry out a Cat N check before buying a used car?
A Cat N check helps you understand whether a vehicle has previously been written off by an insurance company and provides valuable information about its history. Combined with MOT records, mileage history, finance checks and vehicle specifications, it allows you to make a more informed purchasing decision and avoid unexpected surprises after buying.
