In reply to red1200: Plenty of bolts for top roping anchors. None on the face itself. You don’t need permission to use it unless you are a group user though I guess deconflicting with the outdoor centre makes sense.
Access to the top is a path or its a pleasant solo anywhere on the slabs, very shiny at the bottom. Should be an ideal spot for what you need. If she likes it try Hoad Slabs in Ulverston. All the same applies but taller, harder, better view and a great little town adjacent. Great spot
