This is nothing to do with the review of existing PIP awards, your claim is being reassessed.
I assume that your existing award ends in about a year, nearly all PIP claims are reassessed 12 months in advance of it ending using the AR1 Review form.
Although the form is different this is a full review of your claim, the criteria is the same and the Decision that results from this will supersede your existing award, whatever it is.
