Company naming rules

  • Names must not be the “same as” an existing company on the register (ignoring punctuation and common words).
  • Certain words require permission (e.g. “Royal”, “Bank”, “Insurance”).
  • Names must end with “Limited”, “Ltd”, or Welsh equivalents.
  • Names cannot be offensive or suggest a connection to government.
