Does a Cat N car need a new MOT?

A Category N vehicle is an insurance write-off with non-structural damage — think cosmetic panels, electrics, lights or trim — that the insurer decided was uneconomical to repair, but which does not affect the chassis or safety structure.

The MOT question

A Cat N marker does not automatically cancel the existing MOT. If the car still has a valid MOT and has been repaired properly, that certificate remains valid until its expiry date. There is no legal requirement for a fresh MOT purely because of the Cat N record.

That said, if the car has been repaired after significant damage, a new MOT (and an independent inspection) is a sensible way to confirm it is genuinely roadworthy before you rely on it.

Cat N vs Cat S

Cat N — non-structural damage. Keeps its registration; no re-registration needed.
Cat S — structural damage that has been repaired. The DVLA requires it to be re-registered and a new V5C issued before it returns to the road, though a valid MOT can still stand.

Always confirm a write-off category before buying. A repaired Cat N can be good value; a poorly repaired one can be dangerous. Check the record and ask for repair evidence.
