Some Agencies Charge £300 Before Your First Lesson

I just rang a reputable tutoring agency (fleet-tutors) to see how much they would charge for a tutor with an MSc/Phd to come to my house to teach me maths at Degree level.
They wanted
£85 registration fee
£5 per lesson travelling fee if they have to spend longer than 15 minutes travelling (extremely probable)
4 lesson fees up front at £51 per hour.
Basically you have to pay them £300 and if the tutor is not suitable, that is £300 you have lost.
A case for trading standards here I think.
