Short answer: yes. 3D gel and 4D raised plates are road legal in the UK, as long as they meet the same rules as any other number plate. Raised characters aren't banned. What matters is the font, size, spacing, colour and who made the plate.
The law that covers number plates
The Road Vehicles (Display of Registration Marks) Regulations 2001This is the main law for how number plates must look on UK roads: the font, character sizes, spacing, colours and markings. It doesn't say characters must be flat, so raised 3D and 4D characters are allowed if everything else complies.
British Standard BS AU 145eEvery plate fitted from 1 September 2021 must be made to this standard. It sets how tough and reflective the plate must be, and it requires the characters to be a single solid shade of black. 3D gel and 4D acrylic plates can be, and are, made to BS AU 145e.
The Vehicles (Crime) Act 2001Anyone selling number plates must be registered with the DVLA as a Registered Number Plate Supplier and must check the buyer's ID and entitlement to the registration. That's why we ask for your documents at checkout.
What makes a 3D or 4D plate road legal
- Standard font: the official Charles Wright 2001 typeface only. No italic, script or stylised fonts.
- Solid black characters: one shade of black. Two-tone or shaded-effect characters haven't been allowed on new plates since September 2021.
- Correct sizes and spacing: no squashing or moving letters closer together to make words.
- Right background: white on the front, yellow on the rear, reflective, with no patterns or tint.
- Proper markings: the supplier's name and postcode, and the British Standard number (BS AU 145e), shown on the plate.
- Made by a registered supplier who has checked your documents.

So what isn't legal?
A plate becomes a show plate if it uses a non-standard font, changed spacing, a tinted or patterned background, faded or two-tone characters. Show plates are fine for car shows, displays and off-road use, but not on public roads.
Our builder tells you straight away which one you're building. If you pick a show-only option, it switches to show plate so there's no confusion.
What happens if you use illegal plates?
You can be fined up to £1,000, your car can fail its MOT, and the DVLA can withdraw a private registration number if it's displayed incorrectly.
