Thanks for the advice Hoddy, Sorry if the original thread was a bit vague; I am actually planning to work for English builders/developers and English speaking clients to start off with as a self employed Electrician (I have a number of contacts already) and I need to improve my French in order to effectively deal with French clientelle. However the issue that concerns me most is making sure I am operating within the French Electrical regulatory system so that I am able to sign off my own work- I understand that I need a siret no. and there will be occasions where I need the consuel to be involved, but I am unable to get solid answers as to exactly the qualifications/skills I need, and whether my exiting qual.s are transferrable and the route to follow to get them recognised in France. From the other posts I have read, I think I may have to attend a weeks business course in order to gain my siret no. so I can operate as a business legally, but am unsure how to apply for this.
