What Are The Rules On Custom Number Plates In UK?

The law of custom number plates in the UK is pretty simple. In this article, we’re going to go over all the rules you need to know when it comes to customising your car with a personalised registration mark and number plate fixers.

Custom Number Plates & What You Need To Know

Number plates are a great way to personalise your car and make it stand out. You can get number plates from a dealer or private seller, but they will both be regulated by the DVLA, so you should check that they are not stolen before buying them.

Number plates can be made from metal, plastic or even wood and can be made for most cars, including cars like Mini Coopers, which are popular with custom number plate enthusiasts.

Colour Of Your Plate

The colour of the plate should be the same as the colour of your vehicle. The plate should also be visible from 20 metres away in daylight, twilight and at night time. This does not mean that you need to have a dark-coloured car for dark number plates or vice versa; it just means that if you have got a white car, then you don’t have any excuse for having a black number plate!

Size Of Your Plates

When it comes to the size of a custom plate, this depends on the vehicle you’re using. The plate should be in proportion to the size of your vehicle and no smaller than 60mm wide and 100mm high.

The Driver & Vehicle Licensing Agency (DVLA) recommends that you check their website before buying any plates because they change frequently.

Letter And Number Spacing

Letter and number spacing is the distance between each letter and number. The minimum spacing is 2mm, but you can go as high as 2.5mm for your plates. The distance between the letters and numbers is measured from the centre of one letter or number to the centre of the next. So, for example, if you have a plate with four letters in it (like ‘THE’), then there would be a gap between each letter that’s equal to one-quarter of the overall length of your plate (or ¼ x 20cm = 5cm).

Background Colours And Images

The rules governing background colours and images for custom number plates in the UK are strict.

For a start, all custom number plates must have a black or white background, with silver being the only other colour permitted. This rule applies to both text-only and combination plates.

Also, no two vehicles can share a combination of letters and numbers that are identical (meaning that you couldn’t get “007” as your personalised registration). In addition, no two vehicles may display identical combinations of letters and numbers on their number plates; this means that even if your cousin does own an Aston Martin DB5 but doesn’t want to use its ‘DB5’ registration plate because it already belongs to another owner (or is too common), she won’t be able to use yours instead.

As far as pictures go, there’s not much leeway here either; only floral pattern backgrounds are allowed along with geometric patterns such as chequers or tessellations (that’s where shapes fit together perfectly without overlapping), national flags (like England’s St George Cross) and heraldic badges — these include crests such as lions rampant holding shields with arrows pointing downwards — plus symbols representing local authorities like councils and police forces.

The Character Of The Plate Itself

You may only display a custom number plate if it meets each of the following conditions:

  • The plate must be the same size as a standard registration plate. The plates are available in two different sizes, which are known as ‘standard’ and ‘mini’. If your vehicle is registered with DVLA, you can find out which size you need by using the online tool on their website.
  • The custom number plate must be made from reflective material and display a registration mark (the letters HMG). This can either be an individual letter or number combination that uniquely identifies your car – such as F1 for Formula One racing driver Lewis Hamilton – or an alphanumeric code consisting of up to seven letters and/or numbers. For example MM123ABCD

The Letters & Numbers You Use

The size of your number plate is determined by the type of vehicle you have. You can Select from three sizes: small, medium and large. A small number plate measures 310mm x 155mm, a medium is 610mm x 205mm, and a large is 825mm x 305mm.

Your choice of characters will also affect the size of your registration number. Standard characters include letters (A-Z), numbers (0-9) and hyphens (-). Initials can be used in place of an individual letter at no extra cost, but they cannot be incorporated into the overall length of the registration mark without permission from DVLA.
