How do I buy a used car in the UK?

Updated October 2026 · How we answer

Short answerCheck the car's history with the official vehicle services, confirm the V5C registration document, and get an inspection before paying. Dealers and private sellers follow different rules for protection.

Checking the vehicle

In the UK, the registration document, often called the V5C, shows the registered keeper and key details. Compare it with the car and the seller's ID. Vehicle history checks can reveal finance owed on the car, write-offs, or mileage problems, so run one before paying.

Check the MOT history online to see past test results, failures, and advisories. This gives you a clear picture of the car's recent condition.

  • Compare the V5C with the seller's details
  • Run a vehicle history check
  • Review past MOT results
  • Confirm there is no outstanding finance

Protection and paperwork

Dealers have obligations under consumer law, including that the car should match its description and be of satisfactory quality. Private sales offer much less protection, so get a clear written receipt and check the seller carefully.

Rules and fees change, so confirm current details on official government guidance before you buy.

Also ask the seller for service history, receipts, and the number of keys, since a missing key can mean an expensive replacement. Keep every document you receive so the paperwork stays complete for a future resale.

Common mistakes

  • Buying without checking for outstanding finance on the car.
  • Relying only on the MOT certificate instead of reading the history.
  • Paying a private seller without a written receipt.
