It doesn't mean you "need" permeable even if creating new, as long as the water drains to soil on your land or you create something like a soakaway underneath with channels which direct the water there.
I think people have overlooked the word "or" in this explanation:
ou will not need planning permission if a new or replacement driveway of any size uses permeable (or porous) surfacing which allows water to drain through, such as gravel, permeable concrete block paving or porous asphalt, or if the rainwater is directed to a lawn or border to drain naturally
