You might consider NHS Continuous Healthcare (see link) for your friend, whereby all care costs (including care home fees) are paid by the NHS, should they qualify.
https://www.nhs.uk/Conditions/social-care-and-support-guide/Pages/nhs-continuing-care.aspx
A person is assessed by healthcare professionals against the following criteria, and would generally need to score the highest level of need in at least 2 of the 12 categories to qualify.
behaviour
cognition (understanding)
communication
psychological/emotional needs
mobility
nutrition (food and drink)
continence
skin (including wounds and ulcers)
breathing
symptom control through drug therapies and medication
altered states of consciousness
other significant needs
But because the NHS has no spare money – the qualifying bar is set very high to minimise NHS costs.
My late mother was assessed for NHS continuing healthcare – at the time she was house bound (living in her living room), hoisted in and out of bed and dressed by carers, hoisted onto a commode and into an armchair where she sat all day unable to move. She only had limited movement in one arm, which allowed her to feed herself from food and drink placed close by.
Based on the above, her NHS continuing healthcare for mobility was scored at level 2 and her continence was also scored at level 2. When I queried this, the healthcare assessors advised me that this is because her incontinence was being managed since she was wearing incontinence pads. Quite how someone with my mother’s mobility was not assessed as being in the highest level of need, was beyond me.
