(1) The operation of regulation 8 is not affected by the fact that on or after 1st April 1990 but before the relevant day another person became subject to a personal community charge by virtue of the same residence as the eligible person or a related residence, or by the fact that another person becomes so subject on or after the relevant day.
(2) Subject to paragraph (3), regulation 8—
(a) does not apply in the case of a person who became subject to a personal community charge by virtue of a different residence in the period beginning with 1st April 1990 and ending with 31st March 1991; and
(b) ceases to apply in the case of any other person who becomes subject to a personal community charge by virtue of a different residence on or after 1st April 1991, from the date on which he becomes so subject.
(3) Where on or after 1st April 1990 but before the relevant day an eligible person has become subject to a different personal community charge of the same charging authority by virtue of any of the circumstances described in paragraph (4) or on or after the relevant day becomes so subject by virtue of any of those circumstances, regulation 8 shall apply or, as the case may be, continue to apply, to him until he becomes subject to a personal community charge by virtue of a further residence otherwise than in those circumstances.
In this paragraph, “further residence” does not include the residence by virtue of which the person concerned was subject to a charge as mentioned in regulation 7(a).
(4) The circumstances mentioned in paragraph (3) are—
(a) that his existing residence has become uninhabitable by reason of fire, storm, flood or other cause or that it is proposed to carry out major works by way of repair or renovation which make it unreasonable to remain in residence while those works are carried out; or
