Check Car Write-Off Status UK — Is Your Car Written Off?

Official DVLA & DVSA data · Updated 2026

A write-off check verifies whether a vehicle has been declared a total loss by an insurance company. Cars are categorized as Cat S (structural damage) or Cat N (non-structural damage). A write-off history significantly reduces resale value and financing options.

What this check shows

  • Whether the car has been declared a write-off by insurer
  • Write-off category (Cat S, Cat N, Cat D, Cat A, Cat B)
  • Date of declaration
  • Whether it's been repaired and re-registered
  • Insurance claims history

Why this matters

A written-off car is higher-risk. Even if repaired, it has a permanent loss of value (20–40% cheaper than equivalent unwritten cars). Insurance premiums increase, resale is difficult, and some buyers will refuse it entirely. Banks may decline to finance a written-off vehicle.

What drivers miss

Many buyers don't check write-off status. Critical gaps:

  • Cat N vs Cat S: Cat N (non-structural) is cheaper to repair but may have hidden damage. Cat S has structural damage—higher risk.
  • Repaired write-offs: If properly fixed, may be roadworthy. But resale value is permanently 20–40% lower.
  • Insurance difficulty: Some insurers won't cover written-off cars. Those that do charge significantly more.
  • Financing issues: Banks often refuse to lend on written-off vehicles (higher default risk)

Common warning signs

  • Car is recorded as Cat S (structural damage) — repairs may be incomplete, hidden damage risk
  • Cat N (non-structural) but no repair documentation — impossible to verify quality of work
  • Written-off car shows as 'back on road' with V5 reissued — check repair quality carefully
  • No write-off history found but seller says it was repaired — may be unrecorded damage

Can you still drive?

Yes, a repaired write-off can be driven legally. However, it carries higher insurance costs, reduced resale value, and potential structural integrity issues if repairs were poor.

What happens next

If your car is written-off:

  • Check repair history: Request all repair invoices, engineering reports, and paint thickness tests
  • Get a pre-purchase inspection: Hire a mechanic to check for hidden structural damage
  • Budget higher insurance: Premiums may be 20–40% higher than non-written-off equivalent
  • Factor resale loss: Expect 20–40% lower resale value despite repairs

UK write-off categories explained

Cat A: Total destruction. Crushed. Cannot be repaired or driven legally.

Cat B: Severe damage. Can only be used for spare parts. Cannot be driven.

Cat S (formerly D): Structural damage (frame, chassis). Repairable but significant damage. Requires engineering inspection to return to road.

Cat N (formerly C): Non-structural damage (panels, electrics). Usually cheaper to repair. Can return to road with repairs.

How write-off status affects value

  • Non-written car: £15,000 market value (baseline)
  • Cat N (repaired): £12,000–£13,500 (10–20% discount)
  • Cat S (repaired): £9,000–£12,000 (20–40% discount)
  • Cat S/N (unrepaired): £3,000–£6,000 (salvage value only)

What to check if buying a repaired write-off

  • Full repair invoices: From date of write-off to completion (parts, labour, timing)
  • Engineering report: Structural certification (required for Cat S cars)
  • Paint thickness test: Use a meter to check all panels—original paint is optimal
  • Panel alignment: Doors, boot, bonnet should align perfectly. Misalignment = poor repair
  • Professional inspection: Pay £150–£300 for a pre-purchase mechanic inspection
  • MOT history: Check if car passed all MOTs after being repaired (consistent quality)

Insurance implications of written-off cars

Insurance premium increase: 15–40% higher than equivalent non-written-off cars.

Some insurers won't cover: Certain underwriters refuse written-off cars entirely (especially Cat S).

Financing issues: Most banks/lenders won't provide loans on written-off vehicles (higher default risk).

Frequently asked questions

What does 'written off' mean?

Insurance company declares the vehicle a 'total loss' (repair cost exceeds 70–80% of market value). Vehicle is registered in the DVLA database with write-off status.

What are Cat S, Cat N, Cat D, Cat A, Cat B?

Cat A/B are complete write-offs (crushed). Cat D/S/N are repairable. Cat S = structural damage. Cat N = non-structural. Modern cars use Cat S/N only.

Can you buy a written-off car?

Yes. They're legal to buy and drive if repairs are completed and V5 reissued. But resale value is permanently lower and insurance is more expensive.

How do you check if a car is written off?

Use HPI, Experian, or our vehicle checker. Enter the registration and you'll see write-off status instantly. Some checks are free; detailed reports cost £5–£20.

Does a written-off car lose value permanently?

Yes. Even if perfectly repaired, a written-off car is worth 20–40% less than an equivalent non-written car for the rest of its life.
