Preparing to fill in the ADP form

I'm starting to prepare to be transferred from PIP to ADP when my current PIP award runs out. I'm just checking that I should use the PIP guides for ADP as I can't find any that say ADP? Are ADP and PIP basically the same or what is the difference? thanks

Sorry, forgot to ask - in the letter I was sent by DWP I was told I will be transferred to ADP and reviewed by ADP. DO you know if that means that the form I will be sent will be a review type form as opposed to a form to apply for ADP for the very first time (without having previously claimed PIP).

I was sent a review form after I transferred to ADP from PIP. There was an option to tick no change and return a two-page form. There was also a longer form enclosed. That allowed you to tick no change for the descriptors or to report a change. There is a box to fill in details. You can add extra pages if you wish.

I followed the B&W advice for PIP and essentially treated it like a new form. I did however refer to evidence I had previously sent to the DWP without resubmitting it. The only evidence I enclosed was new evidence I had gathered since my last pip claim.

There are lengthy delays. I got the results of my review 7 1/2 months after submitting the form. On a positive note, I kept the same award and my award was for ten years. My previous awards with the DWP were five years and three years.
