I still find it strange that it continues to be paid to those that enter care as it is paid to the individual and does not have to go to the CH.
I also find it strange however on thinking about it I'm not too sure.
On first thoughts they could filter out people who they knew had a
permanent address as a care home in September for the next years non-eligibility.
How do they know that 'Valley Grange' is a care home?
In my experience the various DWP departments don't always share info - confidentiality?
Maybe a decision was made that it was not worth the hassle.
Digressing a bit, up to 2015 all European expats received the WFP.
It was decided to compare the winter temperatures in various countries with that of SW England.
Expats in several countries lost the payment, for all except France the decision was clear cut.
France however included Mayotte (Comoros), Guadeloupe, Réunion, French Guyana and Martinique and WFP was withdrawn even though mainland France has a lower winter temperature than SW England.
If withdrawal of payment of WFP to residents in care homes was easy I feel it might have happened in 2015.
More digression
