> free healthcare (including prescriptions),
For people not in the UK: people in England pay for each item on a prescription. The charge is currently £8.05 per item. You can get discounts if you need multiple items. There are a bunch of exemptions - people with a thyroid problem for example - which mean that about 90% of items are free.
