From standard registration numbers to personalised plates and cherished registrations, there are plenty of ways to identify your vehicle. However, not every registration is allowed on UK roads. Each year, the Driver and Vehicle Licensing Agency (DVLA) blocks a selection of registration combinations that are considered inappropriate or offensive before they are ever released.
If you’re thinking about buying a personalised number plate or simply want to understand how the system works, here’s everything you need to know.

What Are Banned Number Plates?
Banned number plates are registration combinations that the DVLA decides should not be issued because they may cause offence, embarrassment or are considered to be in poor taste.
Before new registration series are released every March and September, the DVLA reviews thousands of potential combinations. Any registrations that could be interpreted as offensive, controversial or inappropriate are removed from sale before they reach the public.
Fortunately, only a very small proportion of registrations are banned each year, leaving millions of combinations available for motorists.
Which Number Plates Were Banned in 2023?
For the 2023 registration release, the DVLA excluded several combinations that referenced recent world events or could be interpreted as offensive.
Examples included registrations that appeared to reference:
- Covid-19
- Brexit
- The war in Ukraine
- Offensive language or inappropriate wording
As with previous years, numerous combinations featuring rude or offensive spellings were also removed from circulation.
The full list changes with every registration release and is determined solely by the DVLA’s internal review process.
What Are the Current DVLA Rules for Number Plates?
Number plates in the UK must meet strict legal requirements.
A legal number plate must:
- Be made from reflective material.
- Display black characters on a white background at the front.
- Display black characters on a yellow background at the rear.
- Have no decorative background patterns that reduce legibility.
- Display the supplier’s details.
- Display the correct British Standard marking (currently BS AU 145e for plates manufactured after September 2021).
Characters must also:
- Be the correct size and spacing.
- Be a single shade of black.
- Not be removable or altered.
- Not be covered with reflective films or tints.
Failure to meet these standards could result in penalties or an MOT failure.

Personalised Number Plates
Private registrations remain perfectly legal provided they comply with DVLA regulations.
When purchasing a personalised registration, you’ll receive the appropriate legal documentation confirming ownership and allowing the registration to be assigned to your vehicle.
Before displaying your new registration, you’ll need the relevant DVLA paperwork confirming the transfer has been completed.
If you later decide to sell your personalised registration, additional documentation will be required to transfer ownership to the new keeper.
As with any vehicle-related purchase, it’s important to ensure you’re buying through legitimate channels and following the correct transfer process.
Can an Illegal Number Plate Fail an MOT?
Yes.
Your number plate forms part of the MOT inspection and must remain clearly visible and legally compliant.
Your vehicle may fail its MOT if the number plate is:
- Damaged or excessively worn.
- Obscured or difficult to read.
- Delaminated.
- Altered with tinted films or decorative coverings.
- Fitted with incorrect spacing or character styles.
- Displaying an illegal background design.
Keeping your number plates clean, undamaged and compliant helps ensure both legal compliance and successful MOT testing.

What Is the Penalty for an Illegal Number Plate?
Using an illegal or incorrectly displayed registration plate can result in a fine of up to £1,000.
In many cases, drivers may initially receive a Vehicle Defect Rectification Notice, giving them a limited period to replace the plate with a legal version.
There have also been proposals to introduce penalty points for certain registration offences, although motorists should always check the latest DVLA guidance for current enforcement rules.
Protecting Your Registration
If you own a personalised registration, it’s worth keeping it clean and ensuring it remains clearly visible at all times.
Criminals occasionally clone vehicle registrations, which can lead to speeding notices or parking fines being issued to innocent motorists. If you suspect your registration has been cloned, you should contact the DVLA and the police as soon as possible.
Conclusion
While millions of registration combinations are available each year, the DVLA continues to remove a small number that could cause offence or confusion.
Whether you’re buying a personalised registration or simply maintaining your existing plates, ensuring they comply with current DVLA regulations will help you avoid fines, MOT issues and unnecessary complications.
With the correct documentation and legal plate design, you can personalise your vehicle while remaining fully compliant with UK law.
