October 1st brings a raft of reforms and new laws that have come into force.
Here are a few to be aware of so you don't get caught out.
Gas prices to be cut by 1.4 percent
Another cut in gas prices - this time by 1.4 percent compared to September - is good news for customers of provider Engie. Prices have now dropped 7.8 percent since the start of the year.
Easier to change phone operators
As of October 1st, it will be easier to change telephone operators while still keeping your home phone number the same. How? Simply use your 12 digit RIO number, a system that has already been in place for many phone operators, but which is now a legal requirement for all.
Keeping your same mobile number while changing operators is already possible in France.
Clearer information on premium phone numbers
The pricing system for France's premium phone numbers (those beginning with 08 or with only four digits) has been a nightmare at best. New rules have sought to simplify the tariffs for these calls, with a new colour coding system.
