I have never so far needed healthcare where EHIC mattered but my wife and several others we know have. The result was seamless attention and good service/treatment in national medical facilities in different countries. EHIC covers emergency treatment only (it is in essence travel insurance) and only under public healthcare rules (unless I am mistaken) but we have, by choice as it was non-emergency, also sought private scans, diagnosis and treatment for my wife outside the UK either in order to circumvent waiting lists in the UK or because it was not available on the NHS. In every case excellent service which puts the World's Best healthcare (NHS to you and me) to shame. Go on TTT, just one "Anti-British" badge, please - I haven't had one for at least two days.
