Hi again all
Yes its all a bit confusing isn't it? This is what the mighty DWP itself says:
'Case Managers are trained DWP staff who are familiar with the legislation governing PIP, but who do not have a healthcare background. The HP enables Case Managers to make fair and accurate decisions by providing impartial, objective and justified advice.1 Jan 2016

PIP assessment guide'
The second sentence about making 'fair and accurate decisions' etc is likely to evoke a somewhat hollow laugh in many claimants!
Kind regards
Mr B
