What is a Cat N car?

Cat N means an insurer wrote the car off after damage that wasn't structural, and it can be repaired. What that means for the log book, getting it back on the road, and buying or selling one.

Facts checked on 12 October 2026

The short answer

A Cat N car was written off by an insurer after damage that wasn't structural, and it can be repaired. It can be used again once it's repaired to a roadworthy condition. An owner keeping a Cat N car can keep its log book.

What Cat N means

Cat N is one of the four insurance write-off categories (A, B, S and N). GOV.UK describes it as a vehicle that “can be repaired following non-structural damage”, and says “you can use the vehicle again if it's repaired to a roadworthy condition”. (GOV.UK)

“N” stands for non-structural: the AA's wording is “non-structurally damaged but repairable”. (The AA) The insurance company decides that a car is written off and which category it goes in. (GOV.UK)

Cat N and the log book

When a written-off car is in Cat N and the owner wants to keep it, GOV.UK says:

  • the insurance company gives the owner an insurance payout and sells the car back to them;
  • “You can keep the log book if you want to keep a category N vehicle.”

For Cat S, GOV.UK lists extra steps: the complete log book goes to the insurer, the owner applies for a free duplicate on form V62, and DVLA records the category in the log book. More in What is a Cat S car?

Cat N and the old Cat D

Cat N has been used since 1 October 2017, when the salvage code changed the categories from A, B, C and D to A, B, S and N, with “a greater focus on the condition of the vehicle rather than repair costs”. (Bodyshop magazine, 14 June 2017)

The old Cat D meant “repairable but repair costs don't exceed pre-accident value”. (The AA) So Cat D was about cost; Cat N is about the kind of damage. They aren't the same category under a new name. Cars written off before October 2017 were given the old letters.

Buying or selling a Cat N car

From trading standards' official guidance for businesses:

  • A trader not telling a consumer that a car “has previously been an insurance write-off” is listed as a misleading omission (Digital Markets, Competition and Consumers Act 2024).
  • Any seller, trader or not, has to describe the car correctly.
  • Selling, offering for sale or supplying an unroadworthy vehicle is illegal under the Road Traffic Act 1988 — for private sellers as well as traders.

Cat N cars on Motorwatchr

Motorwatchr marks a car Cat N only when the advert, the seller or the site's own vehicle check says so — “Cat N, seller says”, with the seller's words quoted and the link to the advert. We never guess a category from photos or price.

Questions

What does Cat N mean?

Cat N is the insurance write-off category for a vehicle that "can be repaired following non-structural damage" (GOV.UK). The AA describes it as "non-structurally damaged but repairable".

Can you drive a Cat N car?

GOV.UK: "You can use the vehicle again if it's repaired to a roadworthy condition."

What happens to the log book of a Cat N car?

GOV.UK: "You can keep the log book if you want to keep a category N vehicle." The extra log book steps — sending the complete log book to the insurer and applying for a duplicate on form V62 — are listed for Cat S.

Is Cat N the same as the old Cat D?

No. Cat D (used before 1 October 2017) meant the repair cost didn't exceed the car's pre-accident value. Cat N is about the kind of damage — not structural — not the repair cost.
