I do wonder if 'influencers' on Social Media have facilitated some claims that shouldn't have passed muster.
As I've said repeatedly when advising PIP claimants there are no magic words.
However. working with genuine claimants, and focusing on the published scoring criteria around, for just one example, getting in and out of an unadapted bath or shower you can move them on quite well.
I think a return to more F2F assessments, particularly where high scores for 'moving around' are sought, would be a good move.
I've no experience of people trying it on for Daily Living but I'm suspicious of several people I've met with Motability cars.
