Buying a Car With a Private Plate: What Must the Seller Transfer?

Before agreeing the car's price, get one point in writing: is the private registration included? It can stay assigned to the car, or the seller can retain it before the sale. Those arrangements require different paperwork.

The physical number plates are not the entitlement. A spare set of plates in the boot does not give you the right to use that registration.

Write the registration into the deal

Record whether the displayed registration is included on the order form or receipt, alongside the VIN. A private number can have its own value even when it appears in every advert photograph.

If the number is excluded, record that the car will be supplied with the registration DVLA assigns after removal. Agree who will provide and fit the correct plates, and whether collection depends on the updated V5C arriving.

Which transfer applies to your purchase?

The number is included and stays on the car

The current V5C should show the registration fitted to the car. Check the make, model and VIN against the vehicle, and follow the normal used-car keeper-change procedure. The seller gives you the green new keeper slip and notifies DVLA of the transfer.

You do not normally need a separate V750 or V778 to keep using a registration already assigned to the car you buy. Those documents relate to entitlement or retention when a number is not being used in the same way.

Our guide to changing the registered keeper explains the handover. Remember that a V5C records the keeper; it is not proof that the seller owns the car free of finance or other claims.

The seller keeps the number

The seller should apply to take the private registration off the car. DVLA normally reassigns the original registration and issues an updated V5C, along with the relevant retention document.

DVLA says the seller must have the retention document and new V5C before selling the vehicle or they risk losing the right to use the private number. An online confirmation that removal has started is not the complete collection paperwork.

Check the replacement registration against the updated V5C and the plates fitted to the car. If these do not match, pause handover and ask the seller to resolve it. Do not agree to drive home using the old plates while a different registration is officially assigned.

Allow for documents to arrive rather than building your collection plan around a promised instant change. A dealer can help coordinate the process, but still needs to provide a clear, correct handover.

A separate registration purchase is a different transaction

If the number is being bought separately rather than staying assigned to this car, establish the V750 or V778 entitlement and the assignment arrangements. For a recently bought used car, wait for the new V5C in your name before applying. Do not swap the physical plates at collection before assignment.

Keep entitlement and retention document references private. A public advert should not contain an unredacted photograph that someone could misuse.

Use the VIN to follow the car through a plate change

A registration change can make old service invoices or adverts look inconsistent. Use the VIN to connect the vehicle and paperwork, and ask for an explanation of the plate history.

Run the usual checks on MOT history, vehicle details, theft or write-off records and outstanding finance. If a paid history report cannot reconcile the previous and current registration, contact its provider before relying on the result.

Our guide to checking outstanding finance covers that separate risk. A valuable private plate does not make a seller's ownership claim stronger.

The registration must match before you drive away

Arrange insurance using the registration actually assigned to the car at collection. If it changes after you obtain a quote, tell the insurer and check the updated documents. Tell the finance provider too if the registration in its paperwork needs correcting.

Tax the car as the new keeper before using it on the road; the seller's tax does not transfer. See how to tax a car online for the relevant reference numbers and process.

Also update any parking permit, congestion-charge, toll or automatic-payment account you set up. These services often identify the vehicle by registration, so an old number can lead to a missed payment or a charge being applied to the wrong car.

At handover, compare the plates, V5C or green slip, receipt, insurance and finance paperwork. Any change of registration should be traceable to the same VIN, with no disagreement about which number was included in the sale.
