PIP light touch review feedback

I had an ongoing PIP award since 2015 for enhanced daily living and enhanced mobility and was sent an AR2 review form which I returned in mid February. My health conditions and needs have not improved since my initial award so I ticked the box to reflect “no change” but also wrote a short paragraph for each of the 3 questions as to why my health conditions and needs were ongoing and why they hadn’t changed and referred them back to my original claim form and medical evidence. I received a decision today, without the need for an assessment, and my award has remained the same with no further review until April 2036. The whole process took just over 8 weeks. I would therefore advise this approach to anyone else who is facing a light touch review.
