I am guessing that your PIP claim from last year resulted in an award for two years!
The vast majority of PIP awards are reassessed a year in advance of the claim ending, if the above is correct then this is a reassessment of your claim and you must complete the form an return it by the required date or your risk your current award being terminated.
Our PIP Claim has all of the current guidance from the DWP to help you complete the form.
What have you received, a new PIP2 or the AR1 review form?
