In reply to flaneur:
I don't know why you are concerned about Freeborn Climbing as all of their staff are professionally qualified to teach climbing. The photo you are concerned about looks a lot more difficult than it probably is and it is a bottom roping set up at a sport climbing venue, probably Portland.
If you want to know more about appropriately qualified climbing instructors have a look at AMI.org.uk or mountain-training.org. Bowles is also a very reputable centre and holds quality badges from the Association of Heads of Outdoor Education Centres (Gold Standard). Any provider climbing outdoors with young people under 18, unless their parents are present, must hold a licence from AALA.
