Yes in our case, it has been a combination of Swiss Franc going up concurrently with Sterling going down- so about 50% loss of income
maddyone - I would love to buy travel insurance, as we always used to from the UK. You obviously have not been following the thread- you can't buy a product which does not exist where you live- as clearly explained. Until Dec. 2020 we will be covered by EHIC, and REGA, Swiss helicopter rescue- which would repatriate us if necessary. Then - we won't be covered in EU at all apart from REGA, and so far- no insurance available here for that purpose. So can you call us foolish- if we were previously covered, but no longer will soon- with no alternative to buy into. A bit unfair, no?
Of course we we go shopping locally in France, or when we go walking, xcountry skiing, etc- a few km from the border- we will just take that chance, and ask friend to pick me up, or ambulance to take me to border ... of course. But shall we accept that we can no longer drive to UK to stay at our holiday place or see GCs. Give up our trips to Italy. Never go and visit sil and bil in Portugal, or drive through to Austria, or ...?
We are in discussion with our insurers who are being great, but the British Embassy in Bern has not got a clue. And neither has the State insurance staff. Probably, as said, we are just a handful finding ourselves in that situation. All the retiree expats I know here have been working here for years, and are not affected.
