Excellent advice from @kmakm. Check what your BUPA cover covers. I was on BUPA for hospital cover (in it for years, never sick, never checked it) and it covered a lot. As indicated, your care is very unlikely to be in any way less in the public system, you just may not get personal continuity of staff. As advised, your GP can help with this. You will end up with a bucket load of knowledge, most of which you never, ever wanted, but you will find your way through this maze so don't panic, deep breath, and keep asking. Lots of people here happy to help. Best wishes.
