I was with Staysure, paying about £110 pa due to several declared conditions and prescriptions. 3 BP tablets, omeprazole, statins and others. In 2015 I had major surgery for bowel cancer and they hiked me up to £631 pa. I paid it for one year as some of the comparison sites refused me cover. I now use the "free" Nationwide cover but pay a supplement of £230 pa, all medical conditions declared. A big saving over Staysure.
