If you’re browsing the used car market, you may come across the term “Cat D car” (short for Category D). But what does it actually mean? And should you buy one? In this guide, we’ll explain the meaning of a Cat D car, how it differs from other insurance write-off categories, and how you can check if a car has ever been written off using tools like Total Car Check.
What Is a Cat D Car?
A Cat D car is a vehicle that has been classified as a Category D insurance write-off. This means the car was damaged in an accident, stolen and recovered, or otherwise compromised, but the insurer decided it was uneconomical to repair through the insurance process.
Importantly, the damage to a Cat D car is usually less severe than Cat C (now known as Cat S), and often the car can be safely repaired and put back on the road. In many cases, Cat D write-offs involve cosmetic damage, minor structural repairs, or theft recovery.
The Difference Between Cat D and Other Write-Off Categories
The DVLA and insurance industry updated write-off categories in 2017, but many cars are still described using the older terms. Here’s how Cat D compares:
- Cat A – Scrap only; must be destroyed.
- Cat B – Vehicle body must be crushed, but some parts may be salvaged.
- Cat C (now Cat S) – Structural damage, but repairable.
- Cat D (now Cat N) – Non-structural damage; repair costs high relative to value.
So, if you see “Cat D” on a used car listing, it usually means the vehicle had non-structural issues that made repair uneconomical for the insurer, but it was later fixed and deemed roadworthy.
Should You Buy a Cat D Car?
Buying a Cat D car can be a good way to save money, but there are risks:
Pros:
- Often significantly cheaper than equivalent non-write-offs.
- May be perfectly safe and reliable if repairs were carried out to a good standard.
Cons:
- Harder to resell.
- Insurance premiums may be higher.
- Repairs might not have been done to manufacturer standards.
Always arrange a professional inspection before purchasing.
