Are HEX Number Plates Legal?
HEX number plates are seeing an increase in popularity once they were not exclusive to someone with a supercar. As a result, we thought we should share some information on this popular and unique plate design.

What are HEX plates?

A hex plate is short for a hexagonal plate. These plates are given this name due to their elongated hexagonal (six-sided) shape, as opposed to the traditional rectangular-styled number plates.
Do I need a Hex Plate?
Hex plates are purely an optional style to apply to your number plate, they only serve an aesthetic purpose, whilst still retaining the durability and intended function of a standard shape number plate.
You don’t necessarily need a hex plate, but for those considering a unique and eye-catching level of customisation for their number plate, hex plates are a valid option.
Will hex plates pass an MOT?
A hex plate has as much of a possibility of failing an MOT as a standard number plate. A plate will fail an MOT if it is not securely attached, presents a hazard or if the characters on the plates do not meet the specification in terms of spacing, colour etc.
What other number plate shapes are available?
This will vary from plate manufacturer, to even the type of car being used. Aside from HEX plates and standard number plate shapes, there are curved corner plates, trapezoid-shaped plates, and other variations similar to the trapezoid shape.
The legality of these plates may vary depending on how they are applied to the vehicle along with if it affects the readability of the characters on the plate. Be sure to confirm the certification of any plate maker before paying

What are the legal requirements for a number plate?
The legal terms that a number plate must adhere to are:
- be made from a reflective material – for road safety
- black display characters on a white background (front plate)
- black display characters on a yellow background (rear plate)
- not have a background pattern – so as not to distort the readability of your plate
- be marked to show who supplied the number plate – to assist with thefts and sourcing queries
- 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.

3D and 4D gel Hex plates
In the previous section, we briefly highlighted our 3D and 4D gel plates. Just to confirm, you are able to choose a 3D or 4D option in conjunction with the hex plate. Below, we will share an in-depth explanation of our gel plate options.
A ‘gel plate’ refers to a registration plate with slightly exaggerated characters that differ from a standard registration plate. Gel plates can come in the form of 3D or 4D plates.
For those looking to add character, impact and a sleek appearance to their car, 3D & 4D plates have seen a surge in popularity as car modification has become common. Their popularity is not only because of their unique and bespoke look but also their increased durability.
As an approved registration plate vendor with years of experience, Bespoke Plates offers this sleek plate upgrade, so for those who are curious, here is a brief description of 3D & 4D gel plates.
3D plates
- Characters placed by hand
- Acrylic plate – polyurethane letters
- Rounded-raised characters with a wet, gel-like look
3D plates are made from acrylic with individual raised letters. The raised letters are manufactured from polyurethane and get ‘stuck’ to the acrylic plate by hand. An aligner bar is used to guarantee perfect spacing.
The rounded and shiny gel-like appearance of 3D plates makes them a great choice if you want to add understated personalisation to your vehicle.
4D plates
- Characters are placed by hand
- Acrylic plate – acrylic letters (laser cut)
- Rectangular and deep-raised characters
4D plates are also made from acrylic, but instead of polyurethane characters, they use professionally laser-cut characters made from acrylic sheets. This allows the characters to be thicker and more rectangular for a more eye-catching look.
4D plates carry a premium over 3D plates by up to 20%. The reason 4D plates cost more is that the individual characters are laser cut, or they are of the thicker gel variety. In the case of laser-cut, the characters are also made to order in-house.
The 3D and 4D plates we offer are available in several styles:
4D plate options
- 4D 3mm
- 4D 5mm
- 4D Gel
- 4D Glitter Gel
- Carbon 4D Gel
- Krystal 4D
- Krystal Gel
3D plate options
- Black
- Carbon Brickwork
- Carbon Galaxy
- Glitter Gel
It’s important to note that with all these different styles, the only change is the texture and appearance of the characters.
