Hi
You can use a European health card for emergencies while you are sorting out your private health care.
Incredibly, there is no way for you to join the Spanish health care system without having a job. There is no system in place.
Sanitas is now a subsidiary of BUPA, so if you have insurance in UK with them, you might be able to negotiate terms with Sanitas.
Even though we are all in the big happy family (???!!) called Europe, in reality nothing is really joined up. All those in Brussels / Strasbourg preen and talk incessantly, only interrupted by incredible lunches, but don't deal with the fine print.
Why do I need a passport to go back to U.K.?
Why can't I have a residencia card like we had before? (Now it's a c$$$$y piece of paper).
Why can't I get healthcare in any European country?
Sorry, but these MEPs have got to get their fingers out - they are costing us all a bomb and doing b$$$$r all.
