Hi luis,
I think in the current time, that based on what you've said, you wouldn't be contacted until 2029 for a PIP review as it's usually around 6 months to 1 year before your PIP award ends. No one is sure as of yet what will happen in the budget - it's best to wait until then, and see what happens, as worrying as it may be. Thousands, if not millions of us, all feel the same.
Chris.
