The new categories are now A, B, S and N. You may also see Categories A and B referred to as ‘actual loss’, and S and N as ‘constructive loss’.
A: Category A refers to cars that are so badly damaged that they can never reappear on the road and even salvageable parts must be destroyed.
B: Category B signifies extensive damage, meaning that the car shouldn’t reappear on the road, although some parts are salvageable.
S (formerly C): Category S means that the car has sustained structural damage, for example a twisted or bent chassis. As the damage is more than cosmetic, the car must be professionally repaired before being deemed safe to drive.
N (formerly D): Category N cars haven’t sustained structural damage, so the issue must be cosmetic or electrical. The car will likely need to be professionally repaired before being deemed safe to drive, as non-structural problems can include brakes, steering or safety features.
