Oic, I was never told about that. My fiance don't really go to get a yearly check up and stuff. I don't know if it's only basic check up is cover or is there a income requirement and stuff. What to do about the prescriptions. If there's a serious health condition would it be cover or would it's best we get insurance now. No idea how the health care system works in UK. I was just wondering what would happen if one day we might want kids and then what's going to happen. The hospital cost and if we need to get insurance for it now and stuff.
Basically the NHS is set up so that everyone in the country is entitled to the same basic treatment for free (at point of service) regardless of their medical or financial situation and they won't have to pay anything for the treatment (it comes out of their taxes instead) - so there are no hospital costs. If you want to have a baby in the UK, all your treatment and your hospital stay will be free, unless you want to pay for private treatment (although if you have to get to a hospital quickly, you may just be rushed to the nearest one and treated on the NHS anyway).
There is no such thing as a 'pre-existing condition' on the NHS because you can get treatment regardless of what is wrong with you and it doesn't matter how serious it is because you will be covered by the NHS anyway. By all means, you can take out private insurance if you want to, but you may find that you won't actually need to use it.
In England, prescriptions are one cost per item (currently £7.20), but in Wales they are all free. In England, if you have a certain condition (e.g. diabetes or thyroid problems), you are pregnant, you are under 16 (or 16-18 and in full-time education) or you are over 60 you automatically get all your prescriptions for free (people on benefits get free prescriptions too, but you wouldn't qualify for benefits on a fiance/spousal visa). All contraception and birth control is free as well
There aren't really any annual check-ups as such in the UK, which is probably why your fiance doesn't get one... because there isn't one to get. Essentially, when you feel ill or you think something might be wrong, you book an appointment with your GP (General Practitioner) and you go get it checked out. If you don't ever feel ill or need a prescription, then you probably won't ever go to the doctor.
