Regulation 59 Date on which change of circumstances is to take effect
:~ There is no ambiguity in HBR 60+ 59 (10)
(10) Paragraph (11) applies if—
(a)the claimant or his partner has attained the age of 65; and
(b)(ii) there has been a change of circumstances in respect of a non-dependant so that the amount of the deduction which falls to be made under regulation 55 (non-dependant deductions) increased.
(11) Where this paragraph applies, the change of circumstances referred to in paragraph (10)(b) shall take effect from the effective date.
(12) In paragraph (11) but subject to paragraph (13), “the effective date” means—
(a) where more than one change of a kind referred to in paragraph (10)(b) relating to the same non-dependant has occurred since—
(i) the date on which the claimant´s entitlement to housing benefit first began; or
(ii) the date which was the last effective date in respect of such a change;
whichever is the later, the date which falls 26 weeks after the date on which the first such change occurred;
(b) where sub-paragraph (a) does not apply, the date which falls 26 weeks after the date on which the change referred to in paragraph (10)(b) occurred
