Karen,
You could have a problem claiming expenses/costs incurred outside the country.e.g UK pastage/couriers etc.
To qualify for the french health system, you must be part of the whole: on the dole; pensioner; or trading/working in the system. Sarko tried to exclude the Brit oldies, but he was overruled by the EU.
People with holiday homes, use the EURO health card and have a top-up to cover the gap.
The EURO card lasts for two years (as far as I know) after you leave SS Britannia, which is in the process of scuttling itself!
Those who live here, but don’t (if you get my meaning) use a complete mutuelle or its equiv, such as BUPA.
The system is complicated, as are most, if you approach it, as it would like you to. However, if you start making any awkward desk jockeys do more than shoving bits of paper round, they soon become very helpful, just to get rid of you.
Incidentally, the term “cottage” translates into “chalet” in french and isn’t used to describe the small french rural houses. They are more often called “fermettes”, unless they are in a village or a large hamlet, were they are referred to as houses.
The local government was changed just before the last local elections for the CG (county councils) You have: counties/departments; cantons; and communes. The number of cantons in the departments were drastically reduced, which resulted in the PS loosing quite a number of seats. Where I am, the department of the Charente had cantons with only five or six communes, then my commune became part of a new canton with 92 communes,. This change reduced the CG chamber to 38 councillors for 19 cantons. Even the leader of the council, Michel Boutant, who had been leader for over 14 years, lost his seat. Each canton has a pair of councillors, as each party's candidates must be in pairs: male and female: a very fair system. (If you need to look at your department, just google cg and the number of the department, e.g. cg16.fr is for the Charente.) Further up the line, the regions (with their own governments) were also trimmed. Poitou-Charente, was to be hived off to Le Centre, but the chaipersons of the departments staged sit-outdides of the Préfectures, demanding to join Aquitaine. The Paris mob relented! That is why Hollande gave his ex girlfriend, Ségolene, the ministry of the environment: because she was the president of Poitou-Charente!! Jobs for the girls, so to speak! Bretagne was left alone, for obvious reasons!
Down here the locals give Paris the finger, and when any Parisiens appear, they start speaking in a mix of Occitan, patois and langue d’Oc, and I’m sure the Bretons have a similar weapon, besides blocking the roads.
The continent is something else!
