Whoops. Just beginning to prepare for a trip into Europe. By pure accident looked at our EHIC's and found mine expired about six weeks ago. I thought
I had set a Google calendar reminder, but perhaps not. Reapplied yesterday and fingers crossed that the new GHIC will appear soon.

BUT the expiry date on the card is 11 Feb 2028 - 11 Feb being the date of his original application. So it is actually only valid for four-and-a-bit years instead of the full five years.
