If you still insist on doing it your self then get a good book to help guide you. There are lots of differences from England such as you can't use twin and earth, NO ring only radial, dis boards use live and neutral switching rcds, double insulated wires, flex conduit, limited amount of sockets per circuits, different size sockets for heaters, washing m/c, dishwashers e.t.c and so on. I'm an English electrician and will be attempting a French rewire next month. A bit of advice. Go to Amazon.fr and buy a book called L'installation électrique by Thierry Gallauziaux and David Fedullo. It has most of the information you will need. This book keeps popping up all over French forums. The only snag, as per all French wiring books, Yes its in French. I have transferred this book onto my computer by scanning and character recognition into word documents and hope to have translated it to rough English before I go but it takes allot of time. So only attempt a rewire if you are clued up and confident. Good luck.
