Are Cat N cars more expensive to insure? The answer is more nuanced than commonly believed. While it’s often assumed that Category N vehicles carry higher insurance premiums, data from Finder UK reveals that Cat N cars can sometimes cost less to insure than equivalent undamaged vehicles. In their comparison, a Cat N version of a 2011 petrol car averaged £553 for insurance, compared to £558 for the undamaged model. According to AUTODOC experts, this variation demonstrates that insurance costs depend heavily on individual circumstances rather than category status alone.
What is a Cat N Car?
A Cat N (Category N) vehicle is a car that has sustained non-structural damage severe enough for an insurance company to declare it a total loss. The Association of British Insurers (ABI) introduced the Cat N classification in 2017, replacing the previous Cat D designation under the Motor Insurance Anti-Fraud and Theft Register (MIAFTR) system.
Cat N damage includes:
Unlike Cat S vehicles, Cat N cars don’t require a Vehicle Identity Check (VIC) before returning to the road, making them easier to repair and resell.
Why Cat N Insurance Costs Vary
Contrary to popular assumptions, Cat N vehicles don’t automatically result in higher insurance costs. The variation in premiums depends on several key factors that affect how insurers assess risk and calculate premiums.
Insurer Policy Differences. Not all insurance companies treat Cat N vehicles the same way. Some insurers avoid Cat N cars entirely or impose premium increases, whilst others don’t differentiate between category and clean vehicles when calculating quotes.
Market Value Impact. Since Cat N cars have reduced market value, insurers may actually charge lower premiums due to reduced potential payout costs in the event of a total loss claim.
Previous Accident History. Cat N cars have documented accident records that some insurers access through the Motor Insurance Database. However, this history doesn’t automatically translate to higher premiums across all insurance providers.
Repair Quality Assessment. Well-documented professional repairs can actually reduce perceived risk. AUTODOC technical team advises that insurers may offer competitive rates when repair quality is clearly demonstrated through:
Driver Profile Influence. Individual factors such as age, location, and driving history often influence premiums more significantly than vehicle category status.

Under the Road Traffic Act 1988, insurers must notify the DVLA when declaring a vehicle Cat N. The DVLA then updates the vehicle’s record, which appears on:
Disclosure Obligations
When Selling: The Consumer Rights Act 2015 requires sellers to disclose Cat N status. Failure to declare category marking constitutes misrepresentation and could void the sale contract.
When Insuring: You must declare Cat N status when obtaining insurance quotes. Non-disclosure could invalidate your policy and result in claim rejection.
