If you purchase a second-hand vehicle, you may hear the term Category A write-off. This is the worst form of insurance write-off, and it means the car is totally beyond repair and has to be scrapped. Category A cars are different from other write-off categories in that they cannot be returned to the road, and even their parts cannot be resold or reused.
But why is a car Category A, and how do you avoid getting ripped off into buying a car that should have been crushed?
Here's what we'll cover in this guide:
- What Category A is and how it differs from other write-offs.
- Why these cars must be scrapped and cannot be salvaged.
- The legal and safety risks of owning a Category A vehicle.
- How insurance companies classify vehicles as Category A.
- How to establish whether a car is a write-off.
- How to avoid scams when purchasing a written-off car.
What Is Category A?
Category A is the worst description of vehicle write-offs. It is where a vehicle has suffered damage so great that it's never safe to ever fix, drive, or even take apart for spares.
These kinds of cars are normally employed in:
- Severe high-speed accidents that make the structure unsalvageable.
- Aggressive fires that soften the car body and internal systems.
- Extreme flood damage causing irreparable electrical and mechanical failures.
- Structural collapse where significant elements like the roof, chassis, or pillars get completely crushed.
After a vehicle is rated Category A, it must be demolished completely at an Authorised Treatment Facility (ATF) according to law.
Why Are Category A Cars Destroyed?
In contrast to other write-off types, Category A cars are so unsafe that nothing on the vehicle is reusable. This is due to:
- The frame itself is too damaged to be repaired, posing a risk to drivers and other motor users.
- Fire-damaged cars release poisonous chemicals, so they are not safe to touch.
- Flood-damaged cars tend to have electrical faults, and these may cause uncontrollable malfunctioning.
- Seriously wrecked cars may have hidden stress fractures that lead to catastrophic failures even after repair.
Because of these risks, Category A cars must be crushed beyond recognition, with no parts sold or reused.
How Is Category A Different from Other Write-Offs?
Understanding the different insurance write-off categories makes it clear why Category A is the worst:
- Category A: The car must be completely destroyed—no reused components.
- Category B: The car won't be driveable, but salvage some virgin parts.
- Category S: The car has structural damage but is repairable.
- Category N: Non-structural damage is caused to the vehicle but needs to be repaired.
How Do Insurers Classify Category A Cars?
Insurance companies determine a vehicle's write-off status via damage assessment and cost estimation. When the repair cost of a car exceeds its market value and is deemed unsafe for use, it will fall under Category A.
Some of the steps are:
- A professional inspection to assess structural damage.
- A cost comparison between repair costs and market value.
- A safety test to determine whether the vehicle is risky.
- If deemed irreparable, the insurer notifies the DVLA and marks the car for destruction.
The Legal Risks of Purchasing a Category A Car
Category A cars must never find their way onto the market, but some unscrupulous traders attempt to hide a car's history and get rid of it secretly. That is why buying one can prove to be a costly folly:
- It is illegal to return a Category A car to the road.
- You cannot insure, tax, or register a Category A vehicle.
- You could be prosecuted criminally or fined for knowingly buying one.
- You won't receive an insurance claim in the event of an accident.
How to Verify If a Car is Category A
To ensure you don't buy a Category A vehicle (or spares from one) unintentionally, follow these:
1. Find the Vehicle Registration Number (VRN)
You should be able to find the VRN on the car's number plate or logbook (V5C).
2. Do a Vehicle History Check
A DVLA check may not always determine write-off status, so use a reliable service to check a car's history. Do a full write-off check to verify its status.
3. Inspect the Report
The report will confirm:
- If the car has been categorized as Category A.
- Insurance write-off history in the past.
- Recorded mileage and previous ownership.
Final Thoughts
Category A write-offs are the most severe classification, meaning the vehicle is completely beyond repair and must be scrapped.
If you’re looking to buy a second-hand car, always run a full history check to make sure it hasn’t been classified as a write-off. Check a vehicle’s write-off status here before making a decision.
