My 2017 PIP Award

Good Afternoon

After I was awarded PIP last year after MR, I put the award letter away in relief. I have come back to it because in the decision section of that letter, it says they have selected the maximum possible review period. At front of letter it mentions from date and for an ongoing period.

Can I ask when, roughly I can expect to be reassessed, based on current practice, in light of the above? I realise claims can be looked at at any time. But if someone received it for say, three years, they have a fairly clear idea of when to get ready. I have none.

Thank you
