Number Plate Fines in the UK: What Can Get You Caught

12 October 2026 · 2 min read

NO F1NENO F1NESHOW PLATE · NOT FOR ROAD USE

Many drivers don't realise their number plates could land them with a fine of up to £1,000. Police officers and automatic number plate recognition (ANPR) cameras are good at spotting plates that aren't right.

The most common number plate offences

  • Wrong font. Italic, stylised or "custom" fonts are illegal. Only Charles Wright 2001 is allowed.
  • Changed spacing. Moving letters closer or further apart to spell a word or name.
  • Coloured or shaded characters. Characters must be solid black.
  • Background patterns or pictures. The background must be plain white at the front and plain yellow at the back.
  • Dirty, cracked or faded plates. If a plate can't be read easily, it can count as an offence.
  • Show plates on the road. Fun to look at, but never legal on a public road.
  • Plates without supplier details. Legal plates must show the supplier's name and postcode and the BS AU 145e mark.

It's not just the fine

Illegal plates can also mean:

  • An MOT failure
  • Problems with your insurance if you're in an accident
  • In serious or repeated cases, the DVLA can withdraw your registration number, which hurts if you've paid for a private plate

How to stay legal

The easy way is to buy from a DVLA registered supplier that makes plates to BS AU 145e. At PlatedUp every road-legal plate is checked, made to the standard and marked correctly, even our 4D and gel plates.
