At minimum you would need a provisional license. Then you can be accompanied by someone who is 21 or over, has a full driving license and has held it for a minimum of 3 years and covers the car they’re supervising you in i.e manual/automatic.
You also need insurance that covers you to drive on a provisional license and also covers the supervising driver.
And the car needs the usuals - mot, tax etc!
I think that’s all. I’m sure I’ll be corrected if I have anything wrong 😊
