19 pence per week Pension Credit

I helped an elderly relative to fill in the on line Government 'form' to see if he might be eligible for Pension Credit. It came back after filling in all the details for him that he would be eligible for 19 pence per week Pension Credit if he applied.

Is it worth his while applying? I'm not sure if this small amount would enable him to be eligible for any other 'passported' type of benefit. At present he does not have any means tested benefits.

Thank you very much for any advice or information
