18The provisions of this Part of this Schedule have effect as respects the amount of rebate or allowance to be granted to a person for a week which is the ninth or any later week in any period for which he, or any person whose income is to be aggregated with his under paragraph 9 of this Schedule, is in receipt of supplementary benefit.
19(1)The said amount shall be the amount if any by which the weekly rent exceeds £1.00 or 40 per cent. of the weekly rent, whichever is the greater, but less any sum in respect of non-dependants as mentioned in paragraph 12 of this Schedule, and subject to paragraphs 13, 14, 15 and 17 of this Schedule.
(2)Paragraph 11 of this Schedule shall not apply where this paragraph applies.
20(1)The last preceding paragraph shall not apply where, assuming it did apply, the amount of supplementary benefit payable for the week would fall to be reduced under paragraph 5 of Schedule 2 to the [1966 c. 20.] Ministry of Social Security Act 1966 (adjustment of benefit to normal earnings), but Part I of this Schedule shall then apply subject to the following provisions of this paragraph.
(2)The weekly income of the tenant and any spouse of the tenant shall be ascertained for the purposes of this Schedule by taking for the rebate period or allowance period the amount of the gross weekly income which the person in receipt of supplementary benefit would have if he were engaged in full time work in his normal occupation, and the amount of any gross income of the spouse, and disregarding to the extent mentioned in paragraph 9(3) of this Schedule any item mentioned in paragraph 9(2) of this Schedule which is included in that income.
(3)The amounts mentioned in sub-paragraph (2) above shall be those amounts as estimated or determined by the Supplementary Benefits Commission.
(4)The preceding provisions of this paragraph shall be in substitution for paragraph 9(1) of this Schedule.
21(1)In this Schedule " period of supplementary benefit" means a continuous period for which the person in question is in receipt of supplementary benefit, but the Secretary of State may give directions as to the circumstances in which two periods of supplementary benefit with a break between are to be regarded as one continuous period.
(2)This Part of this Schedule applies whether or not the period of supplementary benefit began before the coming into operation of the scheme.
