PIP and UC are paid at different periods, PIP is a weekly amount, paid 4 weekly whereas UC is paid monthly.
My understanding is that any changes reflected in your assessment period (25th of previous month to 24 of current month) comes inyo affect when you get paid. UC is paid monthly, in arrears, within 7 days of the end of the monthly assessment period.
So the answer to your question is no.
