Hi Lucas,
Receiving PIP makes no difference technically to your UC - however, I do know some people who have been placed in LCWRA after receiving the higher rate of PIP. I am in the LCW group myself, and had an uphill struggle to be placed in this, despite claiming PIP before it. The assessors were not accurate at all.
Chris.
