you don't need to be on benefits to get a blue badge, but I think when he got to the online page to request on there are two options, if you get disability benefits like PIP at highest rate for mobility, you click it and the blue badge is instant 'yes', otherwise you have to fill in pages of forms explaining the medical reasons why you need one, providing dr details and proof of the disability, I did this for my mum who had COPD and they wanted lists of pills she was taking, dosage, dr evidence etc etc so yes it is more long winded getting a blue badge without benefits but can be done, but actually I am glad they ask for all that to save abuse of the system as there is already too many people abusing blue badges, eg borrowing them from family members, using them even once relative has died, using out of date ones etc
