Our Age UK centre has two different nail cutting services. One is run by a trained podiatrist and one by others (possibly Health Care Assistants or something similar). When OH used their services he had to go to the podiatrist as he was on blood thinking medication at the time. I think it cost £16 last summer and he certainly used an electrical file thingy! Our local community hospital also do a nail cutting service but the first visit there is pretty expensive as you have to buy the supplied clippers etc from them and then take them with you each time. Perhaps the GP's surgery could advise you of any local services?
