Also private insurance will not cover a lot of things here, eg ante natal care and you would have to pay up front for that if you went private. Also bear in mind, if you are in an emergency situation and an ambulance is called, no-one is going to ask you about your insurance, you will be taken to the nearest public Accident & Emergency Dept. So it really depends why you think you need health insurance. This is a first world country and the medical facilitities here are comparable to other first world countries. I wouldn't say insurance was a necessity unless, like Stacey said, you have a particular condition you are worried about, and even then most people wouldn't go private. Some people can get private health insurance at a special rate through their company - if that's your situation then it might be worth taking it up. But if you are a generally healthy person with no special healthcare needs, the NHS is more than adequate.
