Cat N Car Meaning

What do different insurance categories actually mean? It's a question you'll likely ask yourself if you see a Cat N registered car up for sale at well below the value of other cars in a similar condition. 

You want to buy with your eyes wide open, though, so keep reading as we delve deep into the world of insurance categories, explain what all the different categories of write offs mean and if you should consider buying one. Find yourself at the other end of the spectrum? Then we'll explain your rights when you're faced with having to write off your own car. 


Should I buy an insurance write-off?

Like most things in life, buying an insurance write off has its advantages and disadvantages. If you buy a car that's in need of repair, but nothing you can't handle yourself, you could grab a bargain and even make a little money when you sell it on. 

If you're a buyer not a seller, you'll get more car for your money if you buy a Cat N that's been repaired although when you come to sell it, it will still have a lower market value than an identical car that isn't a Cat N. 

Buying a written-off car shouldn't be as off-putting as it sounds. Cat N cars, for example, haven't suffered structural damage and on most cases can be returned to an un-crashed condition relatively easily. 


What is a total loss on a car?

Put simply, your car will be recorded as a total loss when the costs to repair it (to its pre-accident condition) are more than the car's market value before it was damaged. Your car will not be a total loss if the repair costs are less than the car's market value. 

Your insurance policy should contain the words "we indemnify you up to the market value of your vehicle", meaning your insurance company is contracted to repair your car if the repair costs do not exceed its market value – if this is the case, you are legally within your rights to insist the repairs are carried out. To not do this would be a breach of contract on the part of the insurer.


What is a constructive total loss of a car?

A 'constructive total loss' is when you give your insurer consent to write-off your car.  Why would you do this? Maybe that particular car holds sentimental value to you – enough so that you want hold onto it, rather than have it replaced.


Will my insurer offer me the full value of a written-off car?

An insurer should offer you the full value of a written off car prior to any accident damage. That said, insurance companies are businesses and they'll likely make an initial offer towards the bottom end of its market value. You can and should contest this based on the condition of your car pre-accident and the price such a car is going for on the used market. You're unlikely to be offered the best price straight off the bat. 


What about insuring a written off car?

Check with insurers before you hand over any money to buy a car that’s been written off. Insurers are cautious by nature. They want to be sure they’re not going to have to pay out on a hefty personal injury claim caused by the written-off car they’ve covered.

Some won’t cover write-offs at all. Others will make the premium you pay more expensive. Some insurers may even want to see an engineer’s report before they’ll cover a car.

Cat N car meaning

Formerly known as Cat D, a Cat N car means that it hasn't suffered any structural damage and could even be legally drivable. This is the lowest class of insurance write-off and therefore the most likely to be fixed, put back on the road and sold.

Category N damage is non-structural. The only reason the car is written off is because the insurer doesn’t think it makes financial sense to fix it.

The insurance company will pay the owner what they’re entitled to. The car then belongs to the insurer, who will either sell it back to the original owner or put it into a salvage sale.

Although a car may not have suffered structural damage, it still might not be safe to drive. A car could be written off because it’s suffered damage to its brakes, steering or airbags. If you’re buying any car that’s been written off it’s worth paying for a vehicle inspection. You should ask for a full history check to be done: some people may try to pass Category N cars off as undamaged.


Cat S car meaning

Cat S (which used to be called Cat C) damage means that a car has suffered serious damage that is uneconomical to repair. That said, the car can be repaired and once the work has been carried out and deemed safe, the car can return to the road. Buying one of these cars makes sense if you have the tools and mechanical knowledge to repair the car yourself because the cost of your labour is free. In monetary terms at least.  


Cat B car meaning

A Cat B car has suffered serious structural, fire or flood damage to the point that it's not economic to repair and its shell must be crushed. Some parts might be salvable, however, and these parts can legally be used on another cars. 


Cat A car meaning

No part of a Cat A car is salvageable – maybe it was stolen, taken for a joyride and, for good measure, torched. All that really remains is the shell and even it is past its useful life. It goes without saying that a Cat A car can never go back on the road. 

Mostly likely yes, some insurance companies may even refuse you cover, but most will just charge you more. All cars are different though so a classic car – one that is 40-years old or older and more likely to have suffered a knock in its life time, which has been professionally repaired may cost no more to cover than one that has never been involved in an accident. 

You can likely knock between 20-40% off the value of a Cat N car compared to one that has no recorded damage, although the value has a lot to do with how well the car was repaired and what type of car it is. 

There's no legal obligation to but, saying that, most insurance companies will ask and in that case, you'll be legally obliged to answer the question truthfully – signing a deceleration to confirm that you have to the best of your knowledge, given the correct answer to every question. If you don't declare it, your insurance will likely be null and void, anyway.
