Been paid today in full.
Wrathmonk - anyone's circumstances can change at any time. By that logic, we should be claiming it weekly or daily. I suspect I can answer my own Q here though - we are billed termly and extras appear on those bills that need to be claimed each term in arrears. Doesn't really apply to me as the basic bills are more than 111.5% of the basic CEA anyway. Still doesn't explain why there is this 'Window Arrangement' though.
It was always necessary to certify on posting that you were still accompanied (or prevented from being accompanied by the Service (no FQ etc)), but the requirement to be subject to further posting is a relatively new one, and can only be completed by the drafter. All I am saying is that the information is, or should be, there in the system. Then again, maybe it's already too complex as it is.
Computer Says "no".
