Car Write-Off Check

Insurance write-offs don't always disappear. They're recorded.

When an insurer writes off a car, it's categorised A, B, S or N depending on damage severity. Cat A and B are crushed and never return to the road. Cat S (structural damage) and Cat N (non-structural) can return after repair — but must be reported to DVLA, and carry reduced resale value and insurance implications. SortedCheck's paid tiers reveal Cat S and Cat N status, backed by up to £30,000 in data guarantee.

Paid check required

Write-off category requires a paid tier

Insurance write-off records (Cat A, B, S, N) sit in the MIAFTR database — commercial data from Experian, not DVLA. Every paid tier from £4.99 reveals the write-off category if flagged. The free check below returns DVLA + MOT data as supporting context.

UK insurance write-off categories explained

A "write-off" is industry shorthand for a vehicle that an insurer has declared a total loss — meaning the cost of repair has exceeded the economic threshold against the vehicle's pre-accident value. The decision is recorded by the insurer on the Motor Insurance Anti-Fraud and Theft Register (MIAFTR), run by the Association of British Insurers (ABI). MIAFTR is the source of every UK write-off marker you will ever see on a paid history check.

The current four categories (since October 2017)

The ABI replaced the old Cat C and Cat D classifications with Cat S and Cat N on 1 October 2017. The four categories now in force are:

Cars written off before 1 October 2017 still carry their original Cat C or Cat D marker on MIAFTR — the new categories are not retrospectively applied.

What the V5C tells you

If the registered keeper has notified DVLA, the V5C will carry a "previously notified as salvage" marker. This tells you the car has been written off at some point but does not tell you which category. A paid history check returns the category and the date.

A keeper is not legally compelled to notify DVLA after a Cat S or Cat N repair, so absence of the marker does not prove a clean history. The MIAFTR record is the authoritative source.

Insurance and resale impact

Insurers price written-off vehicles individually. Cat S and Cat N cars are typically harder to insure, attract higher premiums, and some insurers decline cover altogether. Resale value is also reduced: a previously written-off vehicle sells for materially less than a clean equivalent, and the gap widens for newer cars.

Should you ever buy a Cat S or Cat N car?

It can be a sensible purchase if the price reflects the history, the repair was carried out by a qualified body-shop with documentation, and you have an independent inspection done. The risks are: poor repair quality, hidden damage that emerges later, harder onward sale, and insurance friction. A Cat S buyer should always commission an independent post-repair inspection — particularly an alignment check and a structural integrity check — before committing.

What about the abolished VIC test?

Until 2015 a Vehicle Identity Check (VIC) was required for older Cat C and Cat B vehicles before they could be re-registered. The test was abolished in October 2015 because the Department for Transport found it was largely ineffective at detecting cloning. There is now no government-mandated post-repair test for Cat S or Cat N vehicles — the only quality control is the body-shop's own work and any optional independent inspection.

Common questions about write-off checks

What is the difference between Cat S and Cat N?

Cat S means the vehicle has had structural damage repaired — to load-bearing or safety-critical components. Cat N means the damage was non-structural: cosmetic, electrical, trim or interior. Cat S is the more serious of the two and harder to insure.

Does a free car check show whether a car has been written off?

No. Write-off data lives on MIAFTR, which is licensed commercially. Free DVLA and DVSA data does not include write-off history. SortedCheck's Protected paid tiers return the category and date.

Can a Cat A or Cat B car ever be put back on the road?

Cat A vehicles cannot — they must be crushed in their entirety. Cat B vehicles cannot return to the road as a whole vehicle, but salvaged parts can be re-used in other cars. If a seller is offering you a Cat A or Cat B car as roadworthy, it is either a fraud or the original write-off was logged incorrectly. Walk away.

Will my insurance go up if I buy a Cat N car?

Often, yes. Some insurers refuse cover for written-off vehicles entirely; those that will cover one tend to load the premium and may require an engineer's report before issuing the policy. Always run an insurance quote on the specific registration before agreeing the purchase.

Frequently asked questions

What is an insurance write-off?

When repair cost exceeds a threshold of the car's pre-accident value, the insurer declares the car a 'total loss' — a write-off. The category (A/B/S/N) records the damage severity.

What do Cat A, B, S, N mean?

Cat A: crush only, no parts salvageable. Cat B: body shell destroyed, parts can be reused, never back on road. Cat S: structural damage, repairable. Cat N: non-structural damage (panels, electrics, cosmetic), repairable.

Can I insure a written-off car?

Cat S and Cat N cars can be insured but some providers decline or charge higher premiums. Always tell your insurer upfront — failing to disclose can void your cover.

Does a write-off appear on the V5C logbook?

It should — but unscrupulous sellers sometimes obtain replacement logbooks that hide it. Always check against a commercial write-off register (our paid tiers) rather than relying on the V5C alone.

What if the seller didn't tell me?

Under the Consumer Rights Act 2015, you may have grounds to reject the car and reclaim your money if a material fact (like a prior write-off) was withheld. Trading Standards and the Motor Ombudsman can help.
