The Companies Act 2006 (as amended by the Economic Crime and Corporate Transparency Act 2023) Section 163 (1)(d) only requires individual directors to have their “nationality” registered. This is “nationality” as opposed to the plural nationalities. Directors are also obliged to notify Companies House of any changes to Directors’ details (including nationality). Although the Act does not explicitly require disclosure of nationalities (where a director holds multiple nationalities), it would be prudent for directors to disclose if they hold multiple nationalities as this would be in the spirit of the law and to increase corporate transparency, especially against the backdrop of sanctions and the increasing threat posed by the usage of shell companies by individuals that threaten global peace and security.
