Regarding NHS Hospitals in UK here is an extract from Essex Rivers Hospital's Inpatient Information. So I guess the NHS offers all assistance necessary to people of any religion - and quite rightly so.

"Religious care

For some people spirituality is expressed in a religious way. Members of the chaplaincy team are available if you need:

a visit from your own faith community
prayer
Holy Communion
Halal or Kosher food
to talk about your faith

Chaplains are members of the hospital staff, trained to provide a high standard of spiritual care. They include Christian, Jewish and Moslem representatives".

In the same way that, I imagine, if I were taken seriously ill enough to need hospitalisation here, in Qatar, if I asked for a Priest I would get one.
