Tesla write-offs: Cat S and Cat N explained
An insurer "writes off" a car when repair would cost too much compared with its value. Electric cars, including Teslas, can be written off after damage that would be repaired on a petrol car.
Why it happens
- Damage near the battery. Insurers and repairers are cautious with high-voltage batteries. Checking or replacing a battery can cost a large share of the car's value.
- Structural parts. Newer Teslas use large single-piece castings. Damage to one can be costly to repair.
- Repair capacity. Few bodyshops are approved for some repairs, so time and cost rise.
The categories
| Category | Meaning | Back on the road? |
|---|---|---|
| Cat A | Scrap only | No |
| Cat B | Body must be crushed; parts can be salvaged | No |
| Cat S | Structural damage, repairable | Yes, after repair; must be re-registered with the DVLA |
| Cat N | Non-structural damage, repairable | Yes |
Buying a written-off Tesla
Cat S and Cat N cars sell for less, but:
- Ask for evidence of how and where it was repaired.
- Check whether Tesla will still provide service, connectivity and Supercharging. Some salvage cars lose access to features or warranty.
- Get a battery health check.
- Insurance may cost more, and resale value will be lower.
