How to Read a V5C Logbook — What to Check When Buying a Used Car
The V5C is the first document you should ask to see when buying a used car — but most buyers do not know what to check beyond the name on the front. Here is a complete section-by-section guide, including the red flags that indicate fraud or hidden problems.
What Is a V5C?
The V5C — officially called the Vehicle Registration Certificate — is a document issued by the DVLA that records a vehicle's registration details and its current registered keeper. It is commonly called a "logbook". Every UK-registered vehicle should have one.
Important: keeper is not the same as owner
The V5C records the registered keeper — the person responsible for taxing and registering the vehicle. It does not record the legal owner. On a financed vehicle, the finance company is the legal owner while the driver is the keeper. The V5C does not prove the seller has the right to sell.
Key Sections to Check
Section 1 — Registered Keeper
The name and address must match the seller in front of you. If the seller says they moved recently, ask for proof. If the name on the V5C is different from the person selling — ask why. A mismatch can indicate the car has been sold on before.
Section 2 — Vehicle Details
Make, model, colour, and body type. Verify these match the physical car. Pay particular attention to colour — a repainted car that does not match the V5C colour could be a write-off repair or accident damage.
Section 3 — Engine
Engine capacity and number. The engine number stamped on the engine block should match. A non-matching engine number can indicate an engine swap — legitimate in some cases, suspicious in others.
Date of First Registration
Verify this matches the registration plate. UK plates encode the registration year (e.g. 66 plate = September 2016). A car with a plate that does not match the registration date has had its plate changed — check for plate change history in a full vehicle report.
Number of Previous Keepers
This field shows the number of previous registered keepers. Cross-reference this against the number shown in a full VEHIXA report — discrepancies can indicate tampering.
V5C Document Reference Number
An 11-digit reference number in the top right corner. Make a note of this — you can verify it against DVLA records. A duplicate or forged V5C will often have an invalid or previously used reference number.
Red Flags on a V5C
- Finance company listed as keeper — outstanding finance has not been cleared. Do not buy without a settlement letter.
- Seller's address is in a different region to where the car is being sold — may indicate a professional dealer posing as a private seller ("trade seller"), which affects your consumer rights.
- Recent keeper change — if the V5C was recently updated, it could mean the car was quickly moved on after a problem was discovered.
- Missing V5C — a common fraud tactic. The seller claims it is "in the post from the DVLA". Walk away unless there is a clear, verifiable explanation.
- V5C sent by email or photo — always inspect the physical document. A photocopy or digital image cannot be verified and is a classic sign of a phantom listing or VIN cloning fraud.
What the V5C Cannot Tell You
Even a genuine V5C does not tell you whether the car has outstanding finance, has been stolen, has been written off, or has had its mileage tampered with. For all of these, you need a full vehicle history check. Run a full VEHIXA report alongside your V5C check — the two together give you a complete picture before you commit.
