The DWP say that for personal Independence payment (PIP) they will take into account aids and appliances that are normally used by the claimant and those which can ‘reasonably be expected’ to be worn or used by the claimant – even if they are not.
DWP guidance goes on to say that:
"Whether use of an aid or appliance could ‘reasonably be expected’ will reflect issues of availability, cost and cultural considerations. For example, it might be reasonable to expect someone to use adapted cutlery or a walking stick, but it would not be reasonable to expect them to use a therapeutic source for feeding or a wheelchair."
