A company must not be registered with a name that is offensive or whose use would constitute an offence (section 53), with a name suggesting a connection with government or a public authority or containing sensitive words without approval (sections 54 to 56), or with a name the same as another in the registrar's index (section 66); the registrar may direct a change of name for similarity, misleading indication of activities or misleading information (sections 67 to 76), and a change of name is made by special resolution or as the articles provide and takes effect on the new certificate (sections 77 to 81). The registrar's rules govern permitted characters and the 'limited' or 'plc' ending.
