Executive coaching qualifications

I am thinking of training and qualifying as an executive coach and am currently looking at 2 options: 1.Henley Professional Certificate, which is accredited by the Association for Coaching, the European Mentoring and Coaching Council and the International Coach Federation (cost £6,250 online) or 2.ILM level 7 Executive Coaching Diploma through the British School of Coaching (cost £4,790 online). My gut feel is that the Henley Certificate is more recognized within the HR community but I was wondering whether any of you have come across either or have any recommendations/thoughts on this? Your feedback would be greatly appreciated:)
