I notice on the AngloInfo Brittany (yes, I know) site that a company called BML Assurance at Dinan is advertising, with reference to full private health assurance. To quote one paragraph of its advert: "For UK citizens who have legally lived in France for five years, you need to obtain a permanent resident certificate from your Prefectures Office, you can then not be refused access into the CMU." The company can be contacted at: contact@angloagence.com - there seems to be a web address www.angloagence.com Usual disclaimers apply - no experience of the agency or connection with the people - we don't even need French health assurance.
