Cat N Car Meaning & Cat S Differences
If you are browsing auction sites like Copart, ASM, or BCA, you will see thousands of vehicles marked as write-offs.
There are four main insurance write-off categories: A and B (must be crushed), and S and N (can be repaired). This guide explains the exact Cat N meaning, the V5C logbook rules, and the insurance reality for 2026.
At a Glance: The Key Differences
- Cat N (Non-Structural): Cosmetic or electrical damage. Safest for private buyers. No V5C surrender required (usually).
- Cat S (Structural): Chassis or frame damage. Requires professional repair. You must re-apply for a V5C logbook.
Cat N Meaning: What is a Cat N Car?
Cat N meaning: Category N stands for "Non-Structural." The insurance company has decided the car is not economical to repair, but the damage has not affected the structural integrity of the chassis or frame.
✅ Common Cat N Damage
- Bumpers, wings, and door panels.
- Headlights and taillights.
- Stolen & Recovered (often minimal damage but no keys).
- Interior damage or minor flood damage.
⚠️ Beware
"Non-structural" does not mean driveable. A Cat N car might have snapped suspension arms, broken steering racks, or deployed airbags. It simply means the metal frame is okay.
Cat S Meaning: Structural Damage Explained
Cat S meaning: Category S stands for "Structural." The vehicle has suffered damage to the main safety cell, chassis rails, crumple zones, or suspension mounting points.
These cars can be repaired safely, but it requires professional equipment (like a jig) to realign the chassis. As a DIY buyer, Cat S is much riskier than Cat N.
| Feature | Cat N (Non-Structural) | Cat S (Structural) |
|---|---|---|
| Damage Type | Cosmetic, Electrical, Suspension | Chassis, A/B Pillars, Crumple Zones |
| Repair Cost | Lower (Bolt-on parts) | High (Requires welding/jig) |
| V5C Logbook | Often retained by owner | Must be surrendered to DVLA |
| Resale Value | -20% to -25% | -30% to -40% |
Cat S Logbook Rules: The V62 Form
One of the most confusing aspects of buying salvage is the V5C logbook. This is where most auction buyers get stuck.
🚫 No V5C for Cat S
If you buy a Cat S car, the insurer is legally required to destroy the original V5C logbook. You will not receive a logbook or a "New Keeper Slip" (Green Slip).
To put a Cat S car back on the road, you must follow these steps:
- Repair the car: Ensure it is roadworthy.
- Insure the car: You need insurance to tax it.
- Apply for a V62 Form: Download the V62 form from GOV.UK.
- Pay the Fee: It costs £25 to apply for a new logbook.
- Wait: Processing usually takes 4-6 weeks. You cannot tax the vehicle at a Post Office until this process is complete.
Buying Advice: The Financials
1. The Discount
You should aim to pay significantly less for a write-off.
Cat N Target: 25-30% below market value.
Cat S Target: 40%+ below market value.
Tip: Use our Auction Calculator to factor in the hidden fees, as fees on salvage cars are often higher.
2. Insurance Premiums
A common myth is that Cat N cars cost double to insure. In reality, most UK insurers (Admiral, Hastings, Direct Line) do not charge extra premiums. However, some insurers may refuse cover entirely.
Crucial Note: If you crash a Cat N car later, the payout will be significantly lower than a standard car because the "Market Value" is lower.
Don't Get Caught Out
Sellers often hide the "Category" status in the description or claim a Cat S was just "light damage."

Frequently Asked Questions
Can I drive a Cat N car straight away?
Legally, yes, provided it is roadworthy, taxed, insured, and has a valid MOT. Unlike Cat S, the DVLA does not require a specific inspection. However, driving a damaged car is illegal if it is dangerous.
What happened to Cat C and Cat D?
In October 2017, the Association of British Insurers (ABI) changed the codes. Cat C became Cat S, and Cat D became Cat N. You may still see C and D on older cars written off before 2017.
Does Cat N need a new MOT?
Not strictly, if the current certificate is valid. However, damage may have occurred after the last test. We recommend checking the MOT history carefully before buying.
