Last time I heard it was between 11-16 weeks but that was several weeks ago. It may have changed now. 

If i go for video call hearing how many months do i need to wait for hearing date.

PIP department called my representative regarding my PIP appeal application. They told my representative they are happy to reward my lower mobility component. I don’t take this reward. 
I am waiting for my tribunal hearing date and still waiting for my hearing bundle. instead they send me bundle 
Today they send me another letter and told me we now have the information we need to decide if we can award personal independence payment (PIP). There are no need to contact us. We will write to you when we have made a decision on your PIP claim.

How long do i need to wait do you know. what will be happened now. Thanks

Why the send me this letter at this stages. I am waiting for bundle from PIP department. when should i get my bundle from PIP department.

thanks
