Hi Adwozere
You can ring the DWP and ask for a copy of the report now. It's called a PA4.
You can send in a copy of the report to be added to your records, but as it wasn't available to the assessor at the time, it is unlikely to influence the decision. If you needed to put in for an MR - you could highlight this new piece of information.
