What Is the V5C?
The V5C, commonly called the log book, is the official vehicle registration document issued by the DVLA. It records the vehicle’s details, such as make, model, engine size, and the registered keeper’s name. The V5C is not the same as the vehicle’s title or ownership certificate, but it is the key paper that proves a vehicle’s identity and its keeper history.
Why the V5C Matters for Used‑Car Buyers
When you’re buying a used car in the UK, the V5C is your first line of evidence that the vehicle is genuine and has not been tampered with. A clean V5C shows:
- No missing or altered registration details.
- No red‑flagged mileage changes.
- No previous keeper changes that could indicate a history of theft or fraud.
However, the V5C alone does not guarantee the car’s condition. It does not include MOT history, insurance write‑off status, or outstanding finance. For a comprehensive picture, you need a full vehicle history report.
What Information Does the V5C Contain?
Key details on the V5C include:
- Vehicle registration number
- Make, model and colour
- Engine size and type
- Previous keepers – each keeper’s name and address
- Date of first registration
It also lists any insurance write‑off categories (Cat A, B, S, N) that have been recorded by the DVLA. These categories indicate the severity of damage and whether the vehicle was written off by insurers. A vehicle marked as Cat A or B has been deemed a total loss, which can affect its value and resale potential.
Limitations of the V5C
While the V5C is essential, it has several limitations:
- It does not show the vehicle’s MOT history – whether the car has passed its annual safety checks.
- It does not reveal any outstanding finance that might still be attached to the vehicle.
- It does not provide a record of previous keepers’ mileage – you’ll need a separate mileage check to detect clocking.
- It does not include the vehicle’s PNC stolen marker status, which indicates if the vehicle has been reported stolen.
Because of these gaps, a V5C should be paired with a detailed vehicle history report for peace of mind.
How to Use the V5C When Buying a Car
1. Verify the registration number – ensure it matches the vehicle you’re inspecting.
2. Check the keeper history – a long list of previous keepers can raise red flags.
3. Look for write‑off categories – any Cat A, B, S or N entries should prompt further investigation.
4. Cross‑reference with a vehicle history check – use a service that pulls DVSA MOT data, insurance write‑off records, PNC markers, and finance status.
Why a Full Vehicle History Check Is Worth It
A comprehensive report will give you:
- Complete MOT history – dates, mileage, and any failures.
- Details of insurance write‑off categories – confirming the V5C entries.
- Information on outstanding finance – ensuring the vehicle isn’t tied to a loan.
- Evidence of stolen or recovered status via PNC markers.
- Insights into previous keepers and any potential mileage discrepancies.
With this data, you can negotiate a fair price and avoid future surprises.

Frequently asked questions
What does the V5C log book show about a car’s previous keepers?
The V5C lists each previous keeper’s name and address along with the dates they held the vehicle. A long keeper history can indicate frequent ownership changes, which may warrant further investigation.
Can the V5C tell me if a car has been written off by an insurer?
Yes, the V5C will include insurance write‑off categories such as Cat A, B, S or N. These categories show the severity of damage and whether the vehicle was declared a total loss.
Is the V5C enough to prove a car’s safety and mileage?
No. The V5C does not contain MOT history or mileage records. For safety and mileage verification, you need a separate vehicle history report that pulls MOT and mileage data from official sources.
