My pip reconsideration was awarded

So basically I was awarded pip standard rates I received a call saying they had awarded me it and I had to accept the decision or go to tribunal I decided to accept the decision then they told me that I would receive 6 months back pay I was wondering if anyone knew how long this usually takes I’ve seen a few posts stating 3-4 days and some saying 3-4 weeks I was told by the person on the phone it wouldn’t take very long to come through would it just be the standard time my bank takes to clear things or could it be longer?
