The short answer
Take the number off before the car changes hands. Don't leave it until the same week, or until the buyer has paid a deposit. Do it before.
You apply online at gov.uk and it costs £80. If the application succeeds, the car usually gets its old registration back straight away. DVLA then posts you a V778 retention document and a new log book showing the replacement number. The number stays on that certificate for ten years, ready for your next car.
gov.uk says it plainly. You must have your V778 and new log book before you scrap or sell the vehicle, or you lose the right to the number. This article is part of our guide to number plates, and it covers the registration only. The sale itself is covered in our guide to selling a car privately.
Why the deadline is absolute
A private registration isn't property you own. DVLA's leaflet INF46 says every registration number is owned by the Secretary of State and allocated to a vehicle. What you paid for is the right to have that number assigned to your car. The right stays with the vehicle unless you move it in time.
INF46 spells out the consequence in one sentence: fail to transfer or retain the number before you sell, and "you'll lose it". The number passes to the new registered keeper along with the car. And DVLA won't sell it back to you: once a registration has been on a vehicle, DVLA says it isn't available to buy from them again.
One more rule matters. Only the registered keeper can apply to move or hold a registration number. The keeper isn't always the owner. That gap matters on a leased car.
Check first: can the number actually move?
Start with the log book. If the V5C says the registration number is non-transferable, you can't retain it. One published cause: register an old vehicle under its original number and you can't transfer or retain it later. An age-related non-suffix or prefix number issued instead is barred too.
Numbers starting with Q or QNI can never be moved and must stay on the vehicle.
The vehicle has its own conditions to meet, listed on gov.uk. It must:
- be registered with DVLA in the UK
- be able to move under its own power
- be of a type that needs an MOT or HGV test certificate
- be available for inspection if DVLA asks
- have been taxed or on SORN continuously for the past 5 years
- be taxed or on SORN right now
The number itself has rules too. Our guide to banned plates and DVLA's rules covers which combinations DVLA refuses.
Taking the number off, step by step
The quick route is DVLA's online service at gov.uk. You need the car's V5C, the 11-digit document reference number printed on it, and a card for the £80 fee. Apply, pay, done.
If the application succeeds, the car's original registration is usually reassigned to it straight away. "Usually" is gov.uk's own word, not ours.
The paperwork follows by post. A new V5C with the replacement registration takes 4 to 6 weeks to arrive. DVLA sends the V778 retention document as well, and it proves your right to the number for the next ten years.
Prefer paper? Use form V317, now published as "Apply to keep a vehicle registration number and put it on another vehicle". Send it to DVLA with the log book and the £80 fee. The address is on the form.
Hold the number, or move it straight across?
The V778 holds your number for 10 years. Renewing it is free, you can apply up to 28 days before expiry, and DVLA must receive the application on or before the expiry date. Miss that date and the right to the number is permanently lost. Neither gov.uk nor INF46 offers any grace period.
Ready to put it on the next car instead? That's a separate application, and gov.uk states it's free online or by post. So the £80 sits entirely on the take-off step. Sellers who budget £160 for a car-to-car move are allowing for a fee that doesn't exist.
The part that loses people their plate: timing
I'd take the number off before the advert even goes up. Not on handover day.
The number comes off immediately if DVLA doesn't need to inspect the car, but the replacement log book takes 4 to 6 weeks. gov.uk says you must have both the V778 and the new V5C before you sell. Build those weeks into your plan, because a buyer with cash won't wait for DVLA.
Once the old number is back on, fit new plates before anyone drives the car. They must come from a registered number plate supplier. INF46 warns that a non-compliant plate risks a fine of up to £1,000, and the number can be permanently withdrawn from use.
Next, update everyone who knows the car by its number. You must tell your insurer about the change. Update any automatic-payment accounts too, such as the Congestion Charge or a Clean Air Zone. gov.uk warns you may get a penalty charge if you enter a zone without updating your details.
Write-offs, theft, leases, scrap and export
The write-off case is the one the internet gets wrong. It's widely claimed that once your insurer pays out, the number becomes theirs. DVLA's own leaflet says otherwise.
You can still apply to transfer or retain the number, as long as the vehicle is available to be inspected and you meet the scheme's normal conditions. DVLA will also ask for an insurer's engineer's report.
You do lose it in one situation. If the insurer settles your claim and sells the vehicle as salvage before the number is retained, it passes with the car to the new keeper. So apply before you accept the settlement, and tell your insurer the number is being kept. DVLA doesn't say what happens when a write-off has already been destroyed, but notice the condition: the vehicle must be available for inspection.
Stolen and not recovered? Apply straight away, by post on the V317.
INF46 sets out the conditions. The theft must be reported to police and updated on the DVLA record, and the car needed valid MOT and tax at the time of the theft. An application more than 2 years and 6 months after the theft is rejected.
There's a wait too. You can't put the number on another car, and DVLA won't issue the V778, until six months have passed from the date of the theft or the vehicle is recovered. After that, contacting DVLA for the document is down to you.
The other cases are quick. Leased car: only the registered keeper can apply, and if that's the leasing company, the right is theirs, so ask them. Scrapped car: the number is withdrawn once the vehicle no longer exists, and it's too late. Export: apply before the vehicle leaves the UK, because DVLA won't accept an application once it's out of the country.
What the buyer sees afterwards
After the take-off, the car goes to its new keeper on its original registration, with a freshly issued V5C. What that fresh issue date does and doesn't mean is covered in how to read a car history check. On the other side of this? If you're buying a car that has someone else's plate on it, what a plate change does to the history trail is the question that matters.
Common questions about keeping a private plate
How much does it cost to take a private plate off a car?
The take-off costs £80, online or by post. Assigning a number you hold on a V750 or V778 to a vehicle is free.
Can I take my private plate off after I've sold the car?
No. Only the registered keeper can apply, and once the car is sold that's the buyer. If the sale went through before you retained the number, it passed to them with the car.
Do I have to wait for the new log book before I sell the car?
Yes. gov.uk says you must have your V778 and the new log book before you scrap or sell the vehicle. Otherwise you lose the right to use the private number.
How long does a retention certificate last, and what does renewal cost?
A V750 or V778 is valid for 10 years and renewing is free. You can apply up to 28 days before expiry, but DVLA must receive it on or before the expiry date. After that, the right to the number is permanently lost.
Can I keep my private plate if the car is written off?
Usually, yes. DVLA's INF46 says you can still apply, as long as the vehicle is available to be inspected. DVLA will also ask for an insurer's engineer's report. You lose the number if the insurer sells the vehicle as salvage before your retention goes through.
Can I take the plate off a leased or financed car?
On a leased car, only the registered keeper can apply. That's usually the leasing company, so the right sits with them. For a financed car where you're the keeper, neither gov.uk nor INF46 mentions finance as a bar. Check your finance agreement before you apply, because it may have its own conditions.
