Car crash damage categories in the UK are a system used to classify the severity of damage to vehicles involved in accidents or incidents. These categories, Cat A, B, S, and N, determine whether a car can be repaired, safely returned to the road, or is destined for the scrap heap. Established by the Association of British Insurers (ABI), the categories ensure transparency for insurers, buyers, and sellers in assessing the condition and value of a vehicle. They categories provide a clear framework to determine a car’s safety, repairability, and future market value.
What Does It Mean When a Car Is Written Off?
A car is written off when the cost of repairs exceeds a percentage of its current market value, or when the damage is so severe that it’s deemed unsafe to drive. This decision is made by an insurance assessor who evaluates the car’s damage and determines its classification.
Write-offs are divided into two main types:
- Repairable write-offs: Cars that can be repaired and safely driven again.
- Non-repairable write-offs: Vehicles that are too damaged to repair and must be scrapped.
This classification affects how the car can be used in the future, its insurability, and its resale value. Knowing which car damage category applies is crucial for making informed decisions.
A Breakdown of Car Crash Damage Categories
Category A: Total Loss, No Salvage
Category A vehicles are the most severely damaged. These cars cannot be repaired or salvaged for parts and must be scrapped entirely. Common examples include vehicles involved in catastrophic accidents or severe fires. Cars classified as Cat A cannot return to the road under any circumstances.
Category B: No Road Use, Parts Salvageable
Cat B vehicles also cannot be repaired and returned to the road. However, unlike Cat A cars, some parts may be salvaged and reused. The body shell must be crushed, ensuring that the vehicle cannot be rebuilt. These vehicles often suffer extensive structural damage, but their engines, electronics, or other components might still be functional.
Category S: Structural Damage, Repairable
Category S applies to vehicles that have sustained structural damage to their chassis or frame. While these cars can be repaired and safely returned to the road, the repairs must be carried out to a professional standard. Buyers of Cat S vehicles should carefully inspect the repair work and ensure all necessary safety checks have been completed.
Category N: Non-Structural Damage, Repairable
Category N is the least severe classification. Cars in this category have sustained non-structural damage, such as cosmetic issues or problems with brakes, suspension, or electrical components. These vehicles are generally easier and cheaper to repair than Cat S cars. However, buyers should still confirm that all repairs meet safety standards before purchasing.
Why Car Crash Damage Categories Matter
Car crash damage categories play a significant role in the used car market. They help buyers and sellers assess the safety, value, and repairability of vehicles. For buyers, knowing the category helps identify potential risks and repair costs. For sellers, it determines how much the car can be sold for and the documentation required.
For instance, a Category N car might be an affordable option for budget-conscious buyers, but its history of damage may lead to higher insurance premiums. Similarly, a Category S vehicle, while repairable, may require significant investment in professional repairs before being roadworthy again.

Buying and Selling Written-Off Vehicles
Buying a car with a write-off classification can be a cost-effective choice, but it comes with certain risks. It’s important to check the car’s crash damage category and understand the implications for repairs, insurance, and resale value. Here are some tips:
- Conduct a Vehicle History Check
Use services like the HPI Check or the GOV.UK MOT history checker to confirm the car’s category and uncover details about previous damage. - Inspect Repairs Thoroughly
For Cat S and N vehicles, ensure that repairs have been completed to a professional standard. A pre-purchase inspection by a qualified mechanic can uncover hidden issues. - Be Aware of Insurance Implications
Cars with a write-off history may attract higher insurance premiums. Always disclose the car’s damage category to your insurer to avoid complications during claims. - Keep Documentation Ready When Selling
If you’re selling a repaired Cat S or N car, provide all necessary documentation, including the V5C logbook and repair invoices. Transparency builds trust and simplifies the sale process.
Legal and Insurance Considerations
Driving or selling a written-off vehicle comes with certain legal and insurance responsibilities. For Category S cars, repairs must be carried out by professionals, and the vehicle must pass a thorough inspection to confirm its roadworthiness. It is illegal to drive a car that has not been properly repaired after being classified as a write-off.
Insurance can also be a challenge. Many insurers require additional documentation, such as an engineer’s report, to confirm that repairs meet safety standards. Additionally, premiums for written-off cars are often higher because insurers view them as higher risk.
Always inform your insurer if you purchase a vehicle with a write-off classification. Failing to do so could result in denied claims or policy cancellations. Also remember that when you are involved in a non-fault accident, if the vehicle is repairable you are entitled to decide where it goes to be repaired.
The Impact of Car Crash Damage Categories on Value
A car’s damage category significantly affects its resale value. Category A and B vehicles are worth very little, as they cannot be returned to the road. These cars are usually sold to scrapyards or dismantlers. In contrast, Category S and N vehicles can be repaired and resold, but they still tend to sell for less than undamaged cars.
For example:
- A Cat S car might sell for 20-30% less than its market value due to its structural damage history.
- A Cat N car could lose 10-20% of its value, depending on the extent of the damage and the quality of repairs.
Buyers should weigh the initial savings against potential long-term costs, such as repairs and higher insurance premiums.
Making Sense of Car Crash Damage Categories
Car damage categories in the UK provide a standardised way to assess the condition of vehicles after an accident or incident. These categories, Cat A, B, S, and N, not only determine a car’s safety and repairability but also affect its resale value and insurance costs. Whether you’re buying or selling, understanding these categories helps you make informed decisions and avoid unexpected surprises.
If you’re dealing with a Category N or S vehicle, professional repairs from trusted experts like Sandown Coachworks can ensure the car is safe and roadworthy. Always prioritise safety, check vehicle histories, and comply with legal requirements to navigate the world of car damage categories confidently.
