Regulation 5 Address for service by post under regulation 3(1)(b)I1
United Kingdom
For the purposes of regulation 3(1)(b), a person’s postal address (or the postal address of their representative) is the postal address provided by that person to the Secretary of State in connection with the giving of documents under the Act.
Where a postal address as referred to in paragraph (1) has not been provided, a person’s postal address is—
where that person is a body corporate, the address of its registered office or principal office, or
where that person is a partnership or an unincorporated association or body, the address of its principal office.
In the case of—
a body corporate registered outside the United Kingdom,
a partnership carrying on business outside the United Kingdom, or
an unincorporated association or body with offices outside the United Kingdom,
the references in paragraph (2) to its principal office include references to its principal office in the United Kingdom (if any).
Where a postal address as referred to in paragraphs (1) and (2) has not been provided or is not known (as the case may be), or if the Secretary of State has reason to believe that such an address is unsuitable or inadequate, a person’s postal address is any postal address by means of which the Secretary of State reasonably believes that the document will come to the attention of that person (or their representative).
