Full state pension can I claim pension credit if I am on pip ?

They will not automatically turn it into a ten year award. You will almost certainly get a PIP review form at some point before your current award end date.

While the review is taking place your normal PIP payments continue until a new decision is made, so you will still be classed as receiving PIP and your Pension Credit will carry on during that time.

Hopefully you will be given a light touch award. Whatever form you receive, treat it like any other review and give as much detail as you can, even if it looks like a simple tick box form. It really does help the decision maker understand your day to day reality. If they can see that your conditions are not likely to improve, a ten year award is certainly possible.
