Over 100mph is a court summons, defiante ban and a definite fine and or points. Amount of each will depend on circumstances e.g. Traffic volume, weather conditions, road conditions etc. licence history also comes in to play.
The day I collectd my ISF i was caught doing 102 on an empty motorway in dry clear and sunny conditions. I received £500 fine, 14 day ban and no points. I had a clean licence at the time.
