They do for courses where bushcraft is an element for youth groups.
I googled and this was the first one that came up.

No connection, there are loads like this.
My Disclosure Scotland is a requirement if I'm working with youth groups or vulnerable adults, I would suspect that the equivalent is needed elsewhere too

Mary,
I'm not sure you've picked a good example there. The activity they are running is heavily water based.
Water based activites would fall under the remit of AALA.
Plus the centre you've highlighted seems to run a wide variety of 'Traditional outdoor pursuits'. To do so to under 18's in the UK means they would have to be AALA accredited, to comply with the relavent legal requirements.
As per the OP I don't think generic lowland 'bushcraft' type of activity would require any accreditation from the AALA.
Looking into the AALA guidelines I'd say trekking would be the activity strand most likely to cover 'Bushcraft'
AALA describes trekking thus:
Trekking
Trekking is journeying on foot, horse or pedal cycle or skiing over terrain which is moorland or more than 600 metres above sea level; and from which it would take more than 30 minutes travelling time to reach any accessible road or refuge; but it does not include skiing on a prepared and marked-out ski-run.The most familiar trekking activities include hill walking, mountaineering, fell running, orienteering, pony trekking, off-road cycling and off-piste skiing.
In your example of a interesting activity combining raft building and some bushcraft.
The rafting element would fall under the remit of AALA because again to quote:
rafts (including those which are inflatable or which are improvised from various materials but excluding those propelled by means of a motor or towed by a motor-boat);
