V5C Logbook Guide (UK)

Owning a car in the UK means handling paperwork as well as wheels. One of the most essential documents you’ll come across is the V5C logbook, often simply called the logbook. The V5C is an important document and serves as the official vehicle logbook for all UK vehicles, recording ownership and registration details. At JDM Plates, we work with vehicle registrations every day, so we know how vital this document is when it comes to identifying your vehicle, assigning number plates, or transferring registrations.

This article is a complete guide to the V5C logbook and vehicle registration certificate, explaining what a V5C logbook is, why it matters, how to read it, and how it links to number plates and legal compliance.

What Is a V5C Logbook?

The V5C logbook, also known as the V5C document, is the official paper document issued by the Driver and Vehicle Licensing Agency (DVLA) that records who is registered as the keeper of a vehicle. As the official record of a vehicle, it contains essential vehicle information, including registration details, VIN, engine specifications, and ownership history. It’s not proof of ownership, but it does show who the DVLA recognises as responsible for the vehicle.

Key things the V5C shows:

• Registered keeper’s name and address
• Vehicle details (make, model, colour, engine size)
• Date of first registration
• Vehicle registration number (your number plate)
• DVLA reference numbers

The V5C logbook is an official document issued by the DVLA and is a four-page document that was blue until 2012, when it was changed to red.

Because the V5C connects the vehicle with its registration number, it’s central whenever number plates are ordered, changed, or transferred.

Why the V5C Matters for Number Plates

At JDM Plates, we’re often asked why the V5C is important when ordering plates, and the answer lies in legal compliance. The V5C, also known as the vehicle registration certificate, proves your legal right to display number plates and ensures your vehicle details are up to date.

It is essential to notify the DVLA and update your V5C logbook whenever there are changes to your vehicle or ownership. This helps avoid fines and ensures accurate records are maintained.

1. Your Number Plate Must Match the V5C

If you order or fit a number plate that doesn’t match the registration shown on the V5C (the vehicle’s log book issued by the DVLA), it’s illegal to use it on UK roads. This can lead to:

• MOT failures
• Fines
• Penalties from police enforcement

2. Assigning a New Plate Affects the V5C

When you buy a private or personalised number plate, it doesn’t automatically appear on your insurance or logbook. Instead, you must assign your private plate through the DVLA process so that it is properly recorded on your V5C. This ensures the private plate is officially linked to your vehicle before you can legally display new plates.

The V5C logbook also includes sections for notifying the DVLA of changes such as your name, address, or significant vehicle modifications.

How to Read Your V5C Logbook

A genuine V5C has a clear layout. The front page of the V5C logbook contains key information, such as the document reference number, which is often required when contacting authorities or insurance companies. You can verify the authenticity of the V5C document by checking for the ‘DVL’ watermark when you hold the logbook up to the light. Here’s how to understand the key sections:

Section 1 – Registered Keeper

This is your name and address, the person responsible for the vehicle.

Section 2 – New Keeper Details

Used when the vehicle changes hands.

Section 3 – SORN Details

Shows if the vehicle is declared off the road.

Section 4 – Vehicle Details

This includes:

• Registration number (your number plate)
• Make and model
• Colour
• VIN (Vehicle Identification Number)
• Engine size

Sections 6 & 8 – Changes and Signatures

These sections are used for reporting changes in ownership or keeper details.

How to Update a V5C Logbook

Updating the V5C is important when:

• You change address
• You buy or sell a vehicle
• You assign a personalised plate
• You import or export a car

Online Update

The quickest way to update keeper or address details is through the official DVLA online service.

Postal Update

If you prefer, you can send changes via mail, but this takes longer, and mistakes can delay processing.

At JDM Plates, we recommend using the online DVLA portal whenever possible for speed and accuracy.

Assigning a New Number Plate to Your Logbook (and Vehicle)

When you buy a private or personalised plate, it doesn’t become legal until it’s officially assigned to your vehicle and updated on the V5C.

Here’s how the process works:

1. Purchase a private or personalised plate
2. Apply to the DVLA to assign the plate to your vehicle
3. Once confirmed, order physical plates from a compliant supplier
4. Your V5C will then be updated with the new registration

Remember:

• You cannot legally display plates that do not match the V5C registration.
• Plates must be manufactured to DVLA and BSAU 145e standards to be road legal; this is where reputable suppliers like JDM Plates come in.

Common V5C Mistakes to Avoid

Here are errors we see drivers make that can cause problems:

• Failing to update your V5C logbook with your current address or ownership details can result in important legal notices, such as those for speeding fines or vehicle tax, being sent to the wrong address. This may cause you to miss deadlines and incur additional penalties.
• Not having a V5C logbook or failing to notify the DVLA of changes can lead to a fine of up to £1,000.
• Forgetting to renew or update your vehicle tax at the same time as updating your V5C can also result in fines or legal issues.

Using Plates That Don’t Match the V5C

Even with the right registration number, a mismatched or mistyped plate on your vehicle is illegal.

Assuming V5C Equals Ownership

The logbook shows the registered keeper, not necessarily the legal owner.

Delaying Updates

If your details change, failing to update the V5C promptly can lead to fines or complications, especially if you need to assign a new number plate.

Lost or Damaged V5C – What You Need to Do

If your V5C is lost, stolen, or damaged:

1. Apply for a replacement logbook via the DVLA
2. You’ll need details such as your registration number, VIN, and keeper information
3. There’s usually a small fee for replacement documents

Once you receive the replacement, check that all details, including your registration number, are correct before ordering plates or making assignments.

Why Keeping Your V5C Updated Matters

Keeping your vehicle logbook (V5C) up to date isn’t just about paperwork; it’s about staying legal and avoiding headaches with:

• Number plate orders
• MOT tests
• Insurance records
• DVLA records

The V5C logbook is especially important when buying or selling a used car. It proves who the registered keeper is, records the previous owner, and contains essential vehicle information such as registration details, VIN, and ownership history. When transferring ownership to a family member or a motor trader, it’s crucial to update the V5C to reflect the new keeper. Motor traders must complete Section 8 and notify the DVLA using Section 9, while the seller should retain Section 4. Insurance companies may also require the V5C logbook if the vehicle is written off or scrapped.

A current V5C means your number plate, vehicle records, and keeper information all align, which makes everything from assigning personalised plates to renewing tax easier. The V5C logbook’s design was revised to enhance customer experience and streamline the process for all users.

If you’re selling a car, follow these steps to stay compliant:

• Complete the ‘new keeper’ section of the V5C and provide the V5C/2 to the buyer.
• Notify the DVLA of the change of ownership immediately after the sale.
• The new keeper must tax the vehicle using the V5C/2 section if needed.
• The seller should destroy the old V5C after the transfer is complete.
• If selling to a motor trader, ensure the trader completes Section 8 and notifies the DVLA with Section 9.
• Failure to notify the DVLA of a vehicle being scrapped or written off can result in fines.
• Selling a car without a V5C is legal but not recommended, as it complicates the process and may reduce the car’s value due to concerns about legitimacy.

The V5C logbook is the backbone of your UK vehicle’s identity. Whether you’re simply checking details, assigning a personalised plate, or ensuring everything is compliant before buying replacement plates, understanding the V5C is essential.
