Will they pay a lump sum?

PiP replaced DLA a lot of people have been caught out by being on DLA and not being aware of changes to each element. Take my advice and join a relevant site which advises in plain English what information they now need. Plus the next move being people who get benefit and are post retirement, looks like they will only get one to ones if they report changes to their health. So in laymen’s terms is you get your current PIP at a good rate it costs them more than they want to pay out because we know what we should get therefore we Appeal. Whereas if it’s a 10 year review a lot of the older generation look at it like “well I might not be here in another 10 years I’ll see what I’m like then” and let any worsening of health go  so they don’t go through the hassle.
ill let you know I had my first PIP and surprisingly got a better outcome, however my review is next April. Do I go for worsening health? My osteoarthritis has gotten worse in my mobility and pain. It would be easier if it comes through with a light review, but I know I’ll need more help soon so I would have to say I need significantly more assistance. But at what price! Don’t know what I’ll do yet!
