What Is a V5C Logbook? The Complete UK Guide (2026)
If you own a car in the UK, you have a V5C logbook — but most drivers have only a vague idea of what it actually is, what it contains, and why it matters. Whether you're buying a used car, selling your vehicle, or trying to work out what to do after losing your paperwork, this guide covers everything you need to know.
Quick Answer: The V5C is the official vehicle registration certificate issued by the DVLA. It records who is the registered keeper of a vehicle and contains key details about the car itself. It is not proof of ownership — but you need it for selling, taxing, and updating your vehicle's details.
What Is a V5C Logbook?
The V5C — officially called the Vehicle Registration Certificate — is a paper document issued by the DVLA (Driver and Vehicle Licensing Agency) to the registered keeper of every vehicle registered in the UK.
It is commonly called the "logbook", a name that dates back to when vehicle records were kept in a physical book format. Today it's a single multi-section document, but the name has stuck.
The V5C serves two main purposes. First, it records who is currently the registered keeper of the vehicle. Second, it provides an official record of the vehicle's key specifications and history.
The DVLA issues a new or updated V5C whenever a vehicle changes keeper, or when certain details about the vehicle change. Every vehicle registered in the UK — cars, vans, motorcycles, and most other motor vehicles — must have one.
What Information Does a V5C Contain?
The V5C is divided into sections, each covering different information.
Vehicle Details:
Registration number, make and model, colour, engine size (cc), fuel type, Vehicle Identification Number (VIN), date of first UK registration, number of previous registered keepers, and whether the vehicle has been imported or exported.
Keeper Details:
Full name and address of the current registered keeper, and the date the current keeper was registered.
Document Details:
An 11-digit document reference number (keep this secure) and the date the current V5C was issued.
Important: The document reference number on your V5C can be used to tax your vehicle or apply for a replacement. Keep it safe and never share it with anyone you do not fully trust.
Registered Keeper vs Owner: An Important Distinction
This is one of the most commonly misunderstood aspects of the V5C, and it matters — particularly when buying or selling a used car.
The V5C document itself states clearly: "This document is not proof of ownership."
The registered keeper is the person responsible for registering and taxing the vehicle — named on the V5C. The legal owner is the person who legally owns the vehicle, and this is not necessarily the same person.
This distinction matters in several situations. With finance agreements, if a car has outstanding finance, the finance company may be the legal owner even though someone else is the registered keeper. With company cars, an employee may drive the car but the company is the registered keeper. With lease vehicles, the leasing company is typically the registered keeper, not the driver.
Always check for outstanding finance separately when buying a used car. The V5C tells you who is the registered keeper — it does not tell you whether someone else has a legal claim over the vehicle.
Run a full HPI Check to verify the V5C and check for hidden finance, theft, write-off, and mileage discrepancy before buying any used car.
Old vs New V5C: What Changed?
There are two versions of the V5C currently in circulation. Both are legally valid, but they look different and the sections are numbered differently.
The old-style V5C was introduced in 2004. It has a blue-green colour and 12 sections, with the new keeper slip in Section 10.
The new-style V5C was introduced in 2012. It has a red-pink colour and 11 sections, with the new keeper slip in Section 6.
Both versions remain valid. The DVLA recommends updating to the new-style V5C, but this is not a legal requirement.
When Do You Need Your V5C?
The V5C sits in a drawer for most of its life — but there are specific situations where you will need it.
Selling your vehicle: You must complete the relevant section and notify the DVLA online or post the completed document to them.
Buying a used car: Always inspect the V5C before purchase. The seller should hand you the new keeper slip on the day.
Taxing your vehicle: You will need the document reference number from the V5C to pay Vehicle Excise Duty online.
Modifying your vehicle: Certain changes — engine swap, colour change, body modification — must be declared to the DVLA.
Writing off or scrapping your car: You must notify the DVLA and surrender or update the V5C.
Changing your name or address: You must update the DVLA so the V5C reflects your current details. Failure to do so can result in a fine of up to £1,000.
Importing or exporting a vehicle: The V5C must be updated or surrendered as part of the process.
Fine reminder: Failing to keep your V5C up to date — for example, not notifying the DVLA of a change of address — can result in a fine of up to £1,000. Updates can be made online at gov.uk in minutes.
How to Check a V5C When Buying a Used Car
The V5C is a key document in any used car transaction. Here is what to check before handing over any money.
Step 1 — Verify the Document is Genuine: Hold it up to light and look for a continuous "DVL" watermark. The background has a multi-coloured pattern that is difficult to reproduce. The paper quality should feel specific — not too thin or smooth.
Step 2 — Check the Details Match the Vehicle: Registration number matches the number plates. Make, model, colour, and engine size match what you are viewing. VIN on the document matches the VIN stamped on the car.
Step 3 — Check the Seller Details: The name on the V5C matches the person selling the car. Ask for photo ID to confirm. If they want to meet somewhere other than the address on the V5C, ask why.
Step 4 — Look at the Issue Date: A brand new V5C on a car with a long history can indicate a replacement was recently issued. Multiple previous keepers in a short time can indicate problems.
Step 5 — Run a Full Vehicle History Check: The V5C alone will not tell you whether the car has outstanding finance, has been written off, reported stolen, or has a clocked odometer. For that, you need a full vehicle history check. Run a full HPI Check before buying any used car.

Frequently Asked Questions
Is the V5C proof of ownership? No. The V5C states clearly that it is not proof of ownership. It identifies the registered keeper — not necessarily the legal owner.
Can I sell a car without a V5C? Yes, but it is significantly more complicated. Replacing the V5C before selling costs £25 and is strongly advisable.
Can I tax my car without a V5C? Yes. If you have recently bought the car, you can use the green new keeper slip to tax it immediately.
How many previous keepers should a car have? There is no hard rule. A high number of keepers relative to the car's age is worth investigating with a full vehicle history check.
What if the VIN on the car doesn't match the V5C? This is a serious red flag and may indicate the car has been cloned or the V5C is fraudulent. Do not proceed with the purchase.
Can I view my V5C online? No. The V5C is a physical paper document only. You can apply for a replacement online but cannot download a digital copy.
Key Takeaways
The V5C is the DVLA-issued vehicle registration certificate — commonly called the logbook. It identifies the registered keeper, not necessarily the legal owner. Always inspect the V5C before buying a used car and verify it matches the vehicle. Run a full vehicle history check alongside the V5C — the logbook alone does not reveal finance, theft, or write-off history. A lost V5C can be replaced online at gov.uk for £25. Failure to keep the V5C up to date can result in a fine of up to £1,000.
Before buying any used car, protect yourself with a full vehicle history check — including V5C verification, outstanding finance, and mileage data.
