What is a vehicle log book (V5C) in the UK

The vehicle log book, officially called the V5C registration certificate, is the legal proof of ownership for a motor vehicle in the UK. Unlike the V5C/2 'new keeper' slip, the full log book must not be kept in the vehicle. Owners should store it securely as it's required for key transactions: selling the vehicle, changing ownership details, or declaring the car off-road (SORN).

Replacing a lost V5C takes about 5 working days when applying online through the DVLA, or longer by post. You'll need the vehicle's registration number, the keeper's driving licence or passport details, and must pay a £25 fee. The process is quicker than reissuing other vehicle documents.

The V5C is essential when selling your car privately, exporting a vehicle, updating personal details after moving house, or scrapping the car. It contains the vehicle's registered keeper history and key specifications. While not needed for routine driving, losing it can delay important admin processes. Always notify the DVLA immediately if it's stolen.
