What Is a Car Insurance Write-Off?
Buying a used car can save money, but it also comes with risks.
Hidden damage, outstanding finance, mileage fraud, or cloned vehicles
can turn a good deal into an expensive mistake.
This used car buying checklist explains exactly what to check before
buying a used car in the UK, helping you spot warning signs and buy with confidence.
1️⃣ Check the Vehicle’s History
- Insurance write-off history
- Outstanding finance
- Stolen vehicle records
- Mileage discrepancies
- Number plate or identity changes
A vehicle history check should be done before viewing the car.
2️⃣ Verify the Registration & VIN
- Registration plates match documents
- VIN visible on windscreen and chassis
- VIN matches the V5C logbook
⚠️ VIN mismatches may indicate cloning or ringing.
3️⃣ Inspect the V5C Logbook
- Original document (not a copy)
- Seller listed as registered keeper
- Vehicle details match the car
- No unexplained “duplicate” markings
4️⃣ Check for Write-Off History
- Cat A / B – Cannot return to the road
- Cat S – Structural damage (repairable)
- Cat N – Non-structural damage (repairable)
Written-off cars should be cheaper and repairs must be verified.
Some insurers may charge higher premiums.
5️⃣ Look for Signs of Accident Damage
- Uneven panel gaps
- Mismatched paint colours
- Overspray on trims or seals
- New parts on an older car
6️⃣ Verify the Mileage
- Wear that doesn’t match mileage
- Inconsistent service records
- Mileage jumps in MOT history
Mileage fraud is still common in the UK.
7️⃣ Review Service History
- Stamped service book or digital record
- Invoices for major work
- Regular servicing intervals
8️⃣ Check MOT History
- Repeated advisories
- Corrosion or structural warnings
- Patterns of neglect
9️⃣ Test Drive the Car
- Straight steering and smooth braking
- No warning lights
- No knocking or unusual noises
- Comfortable clutch and gear changes
🔟 Confirm Insurance & Running Costs
- Get insurance quotes in advance
- Check road tax band
- Research common faults
- Compare fuel economy
✅ Final Advice
- Never rush into a purchase
- Don’t rely on seller assurances alone
- Always verify independently
A vehicle history check can reveal write-offs, finance, theft,
mileage issues, and identity problems.
Check before you buy - not after!
