22. After Schedule 3A M1, insert—
1. Where the amount of state pension credit payable under an award is changed by a superseding decision made on the ground that there has been a relevant change of circumstances, that superseding decision shall take effect from the following days—
(a)for the purpose only of determining the day on which an assessed income period begins under section 9 of the State Pension Credit Act, from the day following the day on which the last previous assessed income period ended; and
(b)except as provided in the following paragraphs, from the day that change occurs or is expected to occur if either of those days is the first day of a benefit week but if it is not from the next following such day.
2. Subject to paragraph 3, where the relevant change is that the claimant’s income (other than deemed income from capital) has changed, the superseding decision shall take effect on the first day of the benefit week in which that change occurs or if that is not practicable in the circumstances of the case, on the first day of the next following benefit week.
3. Paragraph 2 shall not apply where the only relevant change is that working tax credit under the Tax Credits Act 2002 M2 becomes payable or becomes payable at a higher rate.
4. A superseding decision shall take effect from the day the change of circumstances occurs or is expected to occur if—
(a)the person ceases to be or becomes a prisoner, and for this purpose “prisoner” has the same meaning as in regulation 1(2) of the State Pension Credit Regulations; or
(b)whilst entitled to state pension credit a claimant is awarded another social security benefit and in consequence of that award his benefit week changes or is expected to change.
5. In a case where the relevant change of circumstances is that the claimant ceased for one or more days to be a patient, the superseding decision shall take effect from the first day of the benefit week in which the change occurred.
6. In paragraph 5, “patient” means a person (other than a prisoner) who is regarded as receiving free in-patient treatment within the meaning of the Social Security (Hospital In-Patients) Regulations 1975 M3.”
