I think Mark is right. This is because the change of circumstance is a new award or increase of Pension Credit, rather than a reduction or cessation of it. In these circumstances, there can be no question of blaming the claimant for any delay is raising the matter with DWP to start with. He can never be penalised for any delay in the liaison process, the whole thing is ETD driven. His HB goes down from the Monday after the ETD.
Mark raises the question whether this is a new HB claim not already in payment. There is an interesting (? – it is to me anyway) argument here about whether arrears of Savings Credit paid after the effective date of the HB claim, but before that claim is decided, amount to circumstances not obtaining at the date of claim for CSPSSA Sched 7.2 purposes. There are two options as I see it:
– decide the claim on the basis of the claimant’s circumstances as they were known to be at the effective date of the claim, then make a superseding decision under Reg 68B. This way, the claimant gets clean away with the arrears
– treat the arrears of SC as circumstances now known to exist with effect from the date of claim, and include them in the initial decision.
This issue only arises with Savings Credit, because arrears of all other benefits would be taken back to the date of claim in any case as a change of circs, so the outcome would be the same either way.
There must be loads of these cases because of the transitional claims rules.
