Hi.
Although now working in a non related job in Jordan, over the years in the UK I trained hard and took and gained a wide range of different outdoor pursuit and professional education qualifications.
A long time ago in main stream outdoor pursuits, you could get away with experience and serendipity until.........
exactly what you have described above occurred.
The key case is that of the Lyme Bay canoe tragedy where leaders taking kids out onto the sea without the required equipment, skills, experience and qualifications became involved in a series of events which resulted in deaths which could have been avoided if people were properly equipped and the instructors properly trained.
This coupled with several instances of deaths and injuries particularly in school parties changed the occupation, particularly where it related to minors over night.
Then came some very high profile murder and child abuse cases which brought more requirement for people to be suitably vetted if working with children and vulnerable adults. This again added hugely to the complexity of working in the outdoor industry.
I would argue for anyone to be succseful in running a Bushcrft business they would have to meet all of the criteria that fell out of the above instances in the UK.
Without being CRB vetted you would not get any work from the educational world.
without suitable relevent qualifications you would not get work taking them into the hills or "wild Country".
Without liability insurance you put yourself at huge personal libility, without what the insurance companies deem the relevent qualifications for the field, you would not get a lot of work.
Now I appreciate I am talking about "outdoor pursuits" in the widest sense and not Bushcraft per se, but I believe as a template the issues are still relevent.
