When you are shopping for a private number plate, you will find that they are quite expensive- they can run up hundreds and even thousands of pounds. So popular are these vehicle accessories, that in the last 30 years, DVLA has sold 6 million personalised registrations to motorists, generating a staggering £2 billion for the Treasury.
As you can see, there is no shortage of car owners who are prepared to pay hefty sums for a cool number plate.
But why do private number plates cost so much?
In this article, we will explain why custom plates often come with a high price tag.
What was the most expensive private number plate ever bought?
One of the most expensive private plates ever recorded in Britain is ‘25O’, which was purchased for £518,480 by classic car collector John Collins for his £10 million Ferrari!
The luxury car enthusiast bought the private plate to put on his Ferrari 250 Lusso, which once belonged to musician Eric Clapton.
Meanwhile, the most expensive number plate in the world belongs to Emirati businessman Saeed Abdul Ghaffar Khouri. The Arab entrepreneur purchased the number plate ‘1’ for a whopping 52 million dirhams (around £7.2 million).
Why do private number plates cost so much?
So, why do private number plates cost so much?
Well, the reason is, that each private plate is completely unique. No two personalised number plates are ever the same.
Every time a custom plate is manufactured, it has a new, original registration number, with a new letter and number combination.
This creates exclusivity and scarcity when it comes to custom plates, meaning there is a huge demand for popular names, numbers, phrases and slogans.
This hikes the prices up because the original owner has many customers who are willing to buy the plate off them. That is why private number plates are a highly lucrative investment opportunity.
When you don’t want your private plate anymore, you can sell it on and make a profit. Other people might see the value in your plate, as it may reflect their personality or align with traits of their life. So, there will always be buyers who are eager to get their hands on it!

Do private number plates go up in value?
If you take excellent care of your number plate and keep it in good condition, then it may rise in value.
Your personalised number plate is a valuable asset, and you could see a significant return on your investment if you decide to sell it for a profit to an enthusiastic customer. In this case, your plate would have added value.
4D plates are extremely durable, more so than standard and 3D plates. This makes them especially unique and special, which undoubtedly adds more value to them.
What are the legal requirements for private number plates in the UK?
The UK has strict laws about what your number plate should look like on your vehicle.
Firstly, private plates must have either a V750 certificate or a V778 retention document to prove you have the legal ownership and the right to use the bespoke design.
The V750 is the document that assigns the actual registration mark to the new owner. This document will be needed for assigning a plate and for selling in the future.
The V778 is the retention document needed to keep ownership of a private plate and to be able to use it legally on the roads. Valid for ten years, it only needs to be renewed if the plate is not currently assigned to a vehicle.
Also, your number plate must meet the following conditions:
- must be made from a reflective material – for the purpose of road safety.
- must have black display characters on a white background (front plate).
- must have black display characters on a yellow background (rear plate).
- must not have a background pattern – so as not to distort the readability of your plate.
- must be marked to show who supplied the number plate – to assist with thefts and sourcing queries.
- must be marked with a British Standard number – this is ‘BS AU 145e’ for plates fitted after 1 September 2021.
- The characters must not be removable or reflective. If your number plates were fitted after 1 September 2021, they must also be a single shade of black.
Your personalised number plates can also:
- have 3D (raised) characters
- display certain flags, symbols and identifiers
- display a green flash, if you have a zero-emission vehicle
Further recommendations also state the British standard number should be permanently marked, non-retroreflecting, a single colour, and be no less than 3mm x 10mm in size.
If you have incorrectly displayed number plates, you could be fined up to £1,000 and your vehicle may fail its MOT test.

How do I decide between a 3D plate and a 4D plate?
Are you considering buying a 3D or 4D number plate for your vehicle? Both are attractive options, thanks to the eye-catching way in which the lettering and numbers stand out.
To decide which one is more appealing to you, let’s take a look at the difference between 3D and 4D plates:
- Characters placed by hand
- Acrylic plate – polyurethane letters
- Rounded, raised characters with a wet, gel-like look
- Characters placed by hand.
- Characters are thicker and more rectangular.
- Acrylic plate – acrylic letters are laser cut and made from acrylic sheets.
- Rectangular and deep raised characters.
- You can also get 4D plates which have a ‘wet’ look, which are made in the same way as 3D letters, but with a thicker profile.
- 4D number plates are more expensive than 3D plates.
