“5.— Persons treated as engaged in remunerative work (1) Subject to the following provisions of this regulation, for the purposes of section 20(3)(c) of the Act (conditions of entitlement to income support) [now SSCBA, s124(1)(c)], remunerative work is work in which a person is engaged, or, where his hours of work fluctuate, he is engaged on average, for not less than 16 hours a week being work for which payment is made or which is done in expectation of payment. … (2) Subject to paragraph (3B), the number of hours for which a person is engaged in work shall be determined— (a) where no recognisable cycle has been established in respect of a person's work, by reference to the number of hours or, where those hours are likely to fluctuate, the average of the hours, which he is expected to work in a week; (b) where the number of hours for which he is engaged fluctuate, by reference to the average of hours worked over— (i) if there is a recognisable cycle of work, the period of one complete cycle (including, where the cycle involves periods in which the person does no work, those periods but disregarding any other absences); (ii) in any other case, the period of five weeks immediately before the date of claim or the date on which a superseding decision is made under section 10 (decisions superseding earlier decisions) of theSocial Security Act 1998 , or such other length of time as may, in the particular case, enable the person's average hours of work to be determined more accurately. (3) A person shall be treated as engaged in remunerative work during any period for which he is absent from work referred to in paragraph (1) if the absence is either without good cause or by reason of a recognised, customary or other holiday. (3A) A person shall not be treated as engaged in remunerative work on any day on which the person is on maternity leave, paternity leave or adoption leave or is absent from work because he is ill. (3B) [not material] … (5) Subject to paragraph (5A), a person who was, or was treated as being, engaged in remunerative work and in respect of that work earnings to which regulation 35(1)(b) and (d) (earnings of employed earners) applies are paid shall be treated as being engaged in remunerative work for the period for which those earnings are taken into account in accordance with Part V. (5A) [not material] … (7) For the purposes of paragraphs (1) and (2), in determining the number of hours for which a person is engaged in work, that number shall include any time allowed to that person by his employer for a meal or for refreshment, but only where that person is, or expects to be, paid earnings in respect of that time.”
“13. Sums to be deducted in calculating recoverable amounts (1) Subject to paragraph (2), in calculating the amounts recoverable under section 53(1) of the Act or regulation 11 , where there has been an overpayment of benefit, the adjudicating authority shall deduct– (a) any amount which has been offset under Part III ; (b) any additional amount of income support, or state pension credit, or income-based jobseeker's allowance or income-related employment and support allowance which was not payable under the original, or any other, determination, but which should have been determined to be payable– (i) on the basis of the claim as presented to the adjudicating authority, or (ii) on the basis of the claim as it would have appeared had the misrepresentation or non-disclosure been remedied before the determination; but no other deduction shall be made in respect of any other entitlement to benefit which may be, or might have been, determined to exist. (2) Paragraph (1) shall apply to tax credit only where both— (a) the overpayment of benefit referred to in that paragraph, and (b) the amount referred to in sub-paragraph (a) of that paragraph, are tax credit, and with the modification that sub-paragraph (b) of that paragraph is omitted.”
“If, during the currency of an award, an overpayment arises because a claimant ceases to satisfy the conditions of entitlement, but later, and still within the currency of the award, he satisfies the conditions of entitlement, the disentitlement on revision or supersession is not indefinite because he has not made a new claim at the relevant time, but is instead limited to the period where the conditions of entitlement are not satisfied, unless some other ground for disentitlement arises.”
