PIP AR1 form

I have received the AR1 form. Gone into a panic. I had a real fight getting PIP in the first place as my first form was completed by an organisation very badly and I ended up going through MR and sending in extra information and basically correcting what was on the original form which did me no favours at all. My MP also got involved and I was awarded full rate care and standard mobility for 3 years with the possibility of them coming back to me just before the time was up which is what they have done.

I believe after they receive the completed AR1 form with more up to date evidence it will go through a process of being compared with the previous form submitted. My problem is are they going to compare it with the original PIP1 form with its mistakes, or the information submitted with MR that the decision maker award me on.

Thanks for your help.

Thank you for responding so quickly. Can I clarify please.
When you say "your previous assessment" will this include all evidence with the mandatory consideration. (not just the original PIP form which was sent in originally).

Thanks again

Thank you Gordon, sorry to ask again,

Can I ask I was awarded PIP from May 2015 to July 2018 with mention of possible contact after July 2017 and 14 weeks before claim end date. They seem very early (dated 22.7.17)sending me the Award Review form why do you think this is? I have been told it has to go in by 22nd August. This has totally thrown me I went through MR the first time which was sorted in Oct 2015. Advice appreciated.
