Hello DobN

I'm sorry to hear about your Mum's diagnosis. It's a difficult time for you both and understandable that you want to make sure she has as much support as possible. 

I'd suggest contacting Macmillan as they have a specialist benefits advice team that should be able to help with your query about pension credits. 

I hope that you're able to get some answers. 

Best wishes,
