Back Payment of Carers Allowance

I am a carer for my girlfriend and after going backwards and forwards with the DWP for 2 and a half years the tribunal finally awarded her PIP. Can she get back payment for her Carers allowance? If so how would she go about it?

Carers Allowance is for the person who cares for the person receiving PIP, so you, if you meet the other criteria? Ring the Carers UK helpline for further information.
