PIP AR2 no change question

NeuroEve

Hi I am currently getting my ducks in a row as our son was awarded highest rate pip for daily living and mobility. He was given an ongoing award in 2017 and it states we will contact you after May 2027. I am aware the reassessment form could come any time before or after. My main question is do you tick no change as he hasn’t had any changes, and leave it at that or do I provide examples of how his condition continues to affect him. I don’t want to end up writing war and peace but also don’t want to make the mistake of not providing enough information. I have up to date medical information to send and would assume it would be an AR2 form. Any advice would be appreciated.
