Hello,
I'm french too, but my diving lesson is from Switzerland. So first, if you have a french permit de conduire, you have to call the "driver and vehicule licensing agency ".

They will tell you, if you have to take a Uk test or not, I don't have too with mine, normaly you whouldn't need too.
Then, I wanted to learn how to drive in the english side of the road, and not with my husband to avoid any problem, and also because i have a big car !!!
so i found a very nice school in south london, i had only few hours ( 5 hours with driving car ) and (4 with my car with the instructor) and the last part was very important, so now i'm not scared to drive in london with my big car.
my driving instructor was gary. they have automanic ou manual cars. I can't remember the name of the school but you can contact him : 07515 733195.
hope that helps
