If the claimant is already on a passported benefit, they have up to one calendar month in which to make their claim, and if they do so within that time they are entitled from the first day of liability – provided they were in occupation on that day. If they did not move in on the same day as the liability started, but on a later day in the same week, you pay from the first day of occupation. If they move in after the benefit week in which liability began, the date of occupation is the date of claim and you pay from the following Monday.
(See the flowcharts for date of claim/entitlement in the Library section, also Reg 83(5)(b) of the HBR 2006.)
