Category S
The vehicle has suffered damage to its structural framework. That makes the quality of structural repair, alignment and supporting evidence especially important.

Cat S vs Cat N: what's the difference?
Cat S means recorded structural damage. Cat N means recorded non-structural damage. Neither label tells you everything about repair quality, condition or value, so investigate the history before you buy.

THE SIMPLE DIFFERENCE
Cat S is structural. Cat N is non-structural.
Category N
The recorded damage was non-structural, but significant components such as suspension, steering, electronics or safety systems may still have been affected.
A category is a starting point, not a complete condition report. A repaired vehicle may look excellent in photographs while still leaving unanswered questions about what was damaged, who repaired it and how well the work was completed.
WHAT TO CHECK
Ask for evidence of the damage and the repair.
Before-and-after photographs
They can help you understand the scale and location of the original damage rather than relying only on the category label.
Repair invoices
Look for evidence of parts, labour and the business or technician responsible for the repair.
Geometry or structural evidence
For Cat S vehicles in particular, appropriate alignment or structural inspection evidence may be valuable.
Current physical inspection
Panel gaps, paint finish, tyre wear, warning lights, steering behaviour and unusual noises can all justify further investigation.
VALUE AND INSURANCE
A repaired write-off should be judged differently from an equivalent car with no recorded write-off marker.
There is no universal percentage discount for Cat S or Cat N. Value depends on the vehicle, damage severity, repair quality, documentation, mileage, specification, market demand and how easy it may be to insure or resell later.
Before agreeing a price, run a car write-off check and consider contacting your intended insurer with the registration and history.
MOT DOES NOT ANSWER EVERYTHING
A valid MOT is not a certificate of previous accident-repair quality.
An MOT result can be useful for understanding test history, advisories and recorded mileage, but it does not replace an investigation into the quality of historical body or structural repairs. Review the MOT history alongside provenance information rather than treating either one in isolation.
FAQ
Cat S and Cat N questions
What is the main difference between Cat S and Cat N?
Cat S means the vehicle suffered recorded structural damage. Cat N means the recorded damage was non-structural. Both can still involve significant repairs and should be investigated carefully before purchase.
Is Cat N always safer than Cat S?
No. Cat N describes the type of recorded damage, not whether every repair was minor or whether the vehicle is automatically a better buy. Repair quality and the parts affected still matter.
Can a Cat S or Cat N car be driven again?
Vehicles in these categories can return to the road after appropriate repair, but buyers should verify the exact history, condition and current status before purchase.
Will Cat S or Cat N affect value and insurance?
It can. Previous write-off history may affect market value, resale and how an insurer prices or underwrites the vehicle.
