Is this car a Cat S write-off?

What counts as structural damage?

Structural damage affects the parts that give a car its strength in a crash, such as the chassis, crumple zones, suspension mountings, sills and pillars — not just cosmetic panels.

Typical examples include a bent or twisted chassis, a collapsed crumple zone, or damaged wing supports. These are the components that protect occupants in an accident, which is why the category exists and why repairs must be done properly.

Is Cat S the same as the old Cat C?

Yes. Category S replaced the old Category C in October 2017, when the ABI changed the codes to focus on the type of damage rather than the cost of repair.

If you see an older car listed as Cat C, that is the previous label for the same kind of structural write-off. The change means the category now tells you about safety-critical damage, not simply that repairs cost more than the car was worth.

Can a Cat S car go back on the road?

Yes, once it has been properly repaired and made roadworthy. A Cat S car must be re-registered with the DVLA (it gets a new V5C) before it returns to the road, so check the paperwork shows this.

Crucially, the repair is not independently inspected by the DVLA, so there is no official guarantee the work was done well. The re-registration confirms the car can legally be used again, not that the repair is sound — that is for you and an inspector to verify.

Can you insure a Category S car?

Yes, but only once it is fully repaired, and it is usually more expensive to insure than an equivalent car with no write-off history because insurers see it as higher risk.

A few insurers may decline a previously written-off car altogether, so it is wise to get a quote using the registration before you commit to buying.

How much does Cat S affect a car's value?

A repaired Cat S car is typically worth around 20% to 40% less than an equivalent car with a clean history, and it carries the marker for life, so it is harder to sell on.

That lower value is the trade-off: a well-repaired Cat S can be a genuine bargain to buy, but you should expect to take a similar hit when you come to sell it. Never pay clean-history money for one.

How do you check if a car is Cat S?

You check for a Cat S marker by running the registration through a vehicle history check that searches insurance write-off records, then confirming the recorded category and date.

CarVerify checks the registration against MIAFTR write-off records, so you can see whether a car that looks clean was recorded as a Category S total loss.

1. Enter the registration and run a Cat S / write-off check.
2. Look for an insurance write-off marker recorded as Category S.
3. Note the date of the loss and check the V5C shows the car was re-registered.
4. Get an independent inspection of the structural repairs before you buy.

Should you buy a Cat S car?

A well-repaired Cat S car can be a sound, cheaper buy, but only with proof of a professional repair and an independent inspection. Without those, the risk is not worth the saving.

1. Get an independent inspection focused on structural integrity, panel gaps and past repairs.
2. Ask the seller for documentation and photos of the repair work.
3. Confirm the car was re-registered with the DVLA after repair.
4. Get an insurance quote, expect a 20–40% lower price, and run the full write-off check for the wider picture.
