Health care in the United Kingdom is a devolved matter with England, Northern Ireland, Scotland and Wales each having their own systems of publicly funded healthcare, funded by and accountable to separate governments and parliaments. As a result of each country having different policies and priorities, a variety of differences now exist between these systems.
Despite there being separate health services for each country, the performance of the National Health Service (NHS) across the UK can be measured for the purpose of making international comparisons.
Not every NHS treatment in UK is free of charge. There are, for example, charges for dental treatment and, for non-UK residents, charges for hospital treatments, and, depending on how urgent it is, you will usually have to pay in advance.
Treatment in A&E departments, at GP surgeries and under the Mental Health Act remains free for all. However, the NHS will let foreign visitors know up front if care is chargeable before treatment begins.
