Mostly it’s down to you to provide the evidence. Medical evidence is not needed for a successful claim as it’s not about diagnosis.
Even when they do contact GPs the response they get is often useless. Particular these days when most patients don’t see the same GP every time the GP filling out the form often has no idea how patients are impacted by their healthy condition. PIP is all about impact, not diagnosis - although letters confirming a diagnosis, if available, can be helpful in supporting what you say about impact.
