NHS Wales does help people who have dialysis at home to pay their bills. The Welsh renal network pays home dialysis patients' out-of-pocket expenses, i.e. the additional amounts of electricity and water that you use for the purpose of carrying out your dialysis treatment in your own home, as prescribed by their renal team. There are a number of renal charities as well in Wales that also provide financial support if patients are struggling. In addition, all renal patients in Wales have been advised to register with their energy provider on their priority services register. I don't know if there's anything within that information that you can pass on to your constituent that perhaps they haven't looked into as yet.
