V5C Logbook Check: What to Look for Before Buying

What the V5C is — and isn’t

The V5C, or logbook, is the registration certificate for a vehicle. It records who the registered keeper is: the person responsible for taxing the car and the one who gets the letters. That is not the same as the legal owner. A car on finance is usually registered to the driver while the lender owns it; a company car is registered to the employee or the fleet company. The outstanding finance guide explains why that distinction costs buyers money.

It also carries no mileage. The V5C has never recorded odometer readings, so it cannot be used to check whether a car has been clocked. For that, the year-by-year readings on the MOT history are the record to use — the mileage discrepancy guide shows how to read them.

What the V5C is good for is comparison. Every detail on it can be checked against something: the seller, the address, the car itself, or the official vehicle records the free check reads.

The fields to check, one by one

Then look at the document itself. A genuine V5C has a watermark visible when held to the light and is printed on security paper. The current red design has been issued since 2019. An older blue document is not automatically a problem, but the details on it should still match, and a seller who has held the car since before 2019 and never updated anything is worth a question about how long they have actually had it.

Red flags

• A duplicate issued recently. The V5C shows its issue date. A duplicate issued in the last few weeks can be innocent — lost paperwork happens — but it is also how a document is obtained for a car that has changed hands informally or been cloned. Ask when and why.
• The address is a trader’s. A private advert with a V5C registered to a business, a unit or a car lot means you are buying from a trader who is presenting as a private seller. Your rights are different, and so is the reason for the pretence.
• The V5C is for a different colour. A respray with no paperwork, or a document that belongs to another car.
• The seller only has a photo of it. You need the document in your hands to check the watermark, the VIN and the issue date.
• The name on the V5C isn’t the seller’s and there is no explanation. Selling on behalf of a relative is common and fine; a name the seller cannot account for is not.

One rule covers all of them: the V5C is a document to compare, so a detail you cannot compare is a detail you have not checked.

What the V5C won’t tell you

Because the logbook only records keeper and vehicle details, it is silent on everything that makes a used car risky:

• Insurance write-off — a repaired Cat S or Cat N car has an ordinary V5C. See the write-off categories guide.
• Outstanding finance — the lender’s interest is not recorded on the logbook.
• Stolen marker — a cloned car comes with a convincing V5C; the stolen car guide covers what to compare.
• Mileage — never recorded on the V5C, so it cannot confirm or contradict the odometer.
• Plate changes — a car that has worn other registrations shows only its current one.

Those are the checks in the Full History Report: £9.99, one-off, no subscription, delivered instantly, with 60 days’ access. It reports what the industry provenance records hold — including the keeper count and any plate changes — but like every history check it cannot guarantee a car’s past.

After you buy

Once you have paid, the V5C has one more job. The seller keeps the main document and tells the registration authority that the car has changed hands; you keep the green new keeper slip (V5C/2) as proof until your own logbook arrives. The transfer can be done online on GOV.UK in a few minutes, and doing it there and then — while you are both still standing next to the car — is the cleanest way to make sure it happens.

1. Ask the seller to complete the transfer online on the GOV.UK vehicle log book page before you leave, or to fill in and post the paper section.
2. Take the green new keeper slip with you. Do not accept a car without it.
3. Tax the car in your own name before you drive it away — tax does not transfer with the car.
4. Expect your new V5C within a few weeks. If it does not arrive, chase it through GOV.UK rather than the seller.

The used car buying checklist puts the V5C checks alongside everything else to do on the day.
