If you transfer currency from you home country to France, you should consider using a broker. They offer better rates than you will generally get from your own bank and in my experience provide a more user friendly and faster service.
The GBP EURO rate is currently on a 16 month high, if you want to make lump sum or regular transfers I can highly recommend our Currency partner TorFX.
If you would like to keep up to date with the Euro you can subscribe to their free updates on GBP/EUR and EUR/USD by clicking here
