Also, given that most mental health services are available only 9-5, it is going to be prohibitively expensive for a parent to pick their kid up from school regularly to drive them cross-town. Maybe there is a bus they could use, but it would be much harder than going to a wing of the school. Or (speculating whildly on something more complex than I'm representing) maybe they could set up some sort of online videochat therapy so those kids who could afford a £35 android phone and wifi could access therapy from outside school?
