What Names Are Banned in the UK

May 9, 2025

Choosing a name is a deeply personal decision, but in the UK, not every name is legally acceptable. Some names are banned to protect individuals from potential harm or ridicule, and to ensure that legal documents remain clear and standardized. 

This article explores the criteria for banned names in the UK, provides examples of prohibited names, and outlines the consequences of choosing a restricted name.

Legal Framework for Naming in the UK

In the UK, there are several regulatory bodies that oversee name changes and birth registrations, including the General Register Office (GRO), and local registrars. 

While parents generally have the freedom to choose their child’s name, certain restrictions are in place to prevent inappropriate or problematic names.

According to UK law, names can be rejected if they:

  • Contain offensive language or obscenity.
  • Include symbols, numbers, or punctuation marks that are not standard characters.
  • Are excessively long or difficult to pronounce.
  • Are likely to cause confusion or misrepresentation.
  • Are deemed inappropriate or contrary to public policy.

Criteria for Banning Names in the UK

The GRO and other legal authorities may reject names based on the following criteria:

  1. Offensive Language: Names that contain curse words, racial slurs, or other offensive language are outright banned.
  2. Obscenity and Vulgarity: Explicit or sexually suggestive names will not be accepted.
  3. Potential for Harm or Ridicule: Names that could potentially subject a child to ridicule or harm, such as naming a child after a notorious criminal, are often rejected.
  4. Misleading Names: Names that may cause confusion, such as titles like “King,” “Queen,” or “Doctor,” can be rejected to prevent misrepresentation.
  5. Symbols and Numbers: Names that include numbers, punctuation, or symbols (e.g., “@,” “#,” “%”) are typically disallowed.

Examples of Banned Names in the UK

While the UK does not maintain a publicly available list of banned names, there have been several notable cases where names were rejected. Examples include:

  • “Cyanide” – Rejected for its association with a deadly poison.
  • “Martian” – Rejected as it may subject the child to ridicule.
  • “King” – Rejected to prevent confusion with official titles.
  • “Princess” – Rejected for its misleading implications.

Comparisons with Other Countries

Some other countries, such as New Zealand, Germany, and Iceland, have similar restrictions on names. In New Zealand, names like “Lucifer,” “Anal,” and “4Real” were banned for being either offensive or too unconventional. In Germany, names like “Adolf Hitler” and “Osama Bin Laden” were banned to prevent harm and ridicule.

Notable Legal Cases

Cyanide and Preacher Case: A mother attempted to name her twins “Cyanide” and “Preacher.” The court ruled that “Cyanide” was unacceptable due to its association with poison, but “Preacher” was allowed as it did not meet the criteria for a ban.

Consequences of Choosing a Banned Name

If a name is deemed unacceptable by the GRO, parents will be required to choose a different name. Legal documents, including birth certificates and passports, may not be issued until a compliant name is selected.

Additionally, if a name is deemed inappropriate after it has been registered, the authorities may take legal action to have the name changed. In extreme cases, the court may intervene to protect the welfare of the child.

How to Choose an Acceptable Name

To avoid issues with name registration, consider the following guidelines:

  • Avoid offensive or vulgar language.
  • Refrain from using symbols, punctuation, or numbers.
  • Keep the name relatively short and easy to spell.
  • Ensure the name does not mimic official titles or ranks.

Conclusion

While the UK allows considerable freedom in choosing names, there are specific restrictions in place to prevent harm, confusion, and misrepresentation. By understanding these guidelines, parents and individuals can avoid legal complications and ensure that their chosen name is legally recognized.
