This is called the helical rim. You do not "have to" fix any of it. It is elective for cosmetic purposes. This can be done under straight local anesthesia with predictably good results. I have no idea of the costs in the UK. My fees would be in the $1500-$2000 for this procedure on both ears done under local anesthesia.
A small procedure can be performed with an inconspicuous incision from behind the ear to weaken the ear cartilage that is causing the point in the superior helix. Best wishes!
