I defer to your knowledge of the situation in th UK.

Our licensing bodies don't work that way. Their aim is to get their members' material used - fee gouging would defeat that aim.

But my question remains unanswered: How much does the school charge each student per hour of instruction?

It doesn't seem to me that one pound per business day would be an oppressive fee. Last time I was in London that was about the price of a Cadbury bar.
