Hi Tom,
If people have feedback to leave about a training centre they would do so here:
www.tilersforums.co.uk/tiling-courses-feedback/
If you can't find out enough about it there then you might be safer picking on of the others that does have plenty of feedback.
I'll have to close this thread as it will just encourage everybody to reply with what they have said before.
Please checkout the feedback forum for info on feedback.
