Hi, wife has bowel cancer and has not worked since may. Since then she has had stoma bag fitted, radiotherapy and now undergoing chemo. She worked part time and her hours/pay means she is not entitled to sick pay. I therefore applied for ESA for her but this has been turned down as she has not paid NI contributions in last 2 years. No NI has been paid due to her work income being below NI threshold. Is this an avenue to appeal decision? or is ESA only applicable where NI paid or credits received. She can't get universal credit. Thanks
