Admin questions about PIP MR request

Hi,

I have a couple of questions about sending my MR request - it's late and I'm aware they do not have to accept it but I've provided all of my reasons along with evidence in a letter.

I firstly wanted to ask what might be an annoyingly frequently asked question but I haven't been able to find - is anyone aware which address you send a PIP MR request to? I was guessing perhaps the 'Post handling site A' in Wolverhampton but want to be certain this is correct.

Secondly, I've been writing a letter with some support for a friend listing the reasons my request is late and I've also written in the same letter the reasons for my request/ the things I felt the DWP did not get right in my report. After writing the letter, I've just seen that there's actually a MR form online that can be filled out, the CRMR1 form. Does this have to be how the MR is requested, or will my letter be okay?

I ask as there isn't really enough room on the form for all of the information I have, even with the section for extra info at the end. I've been as detailed as I possibly can in my letter about the reasons for lateness and the things wrong with the report and I really don't want to condense it and lose valuable information. Will my letter be okay, or must it be done via a CRMR1 form?

Thanks very much for any advice,

Clare
