Hypnosis Accreditation in the UK! Is there any?

Hypnotherapy is currently UNREGULATED in the UK and there is no national or international organization that is solely responsible for hypnotherapy accreditation. In reality, anybody can self-accredit, and they do!
So, how do you navigate through the minefield of accredited hypnotherapist schools?
Find a professional organization that has academic standards.
I could only find two… 

One: The British Society of Clinical and Academic Hypnosis (BSCAH)
In addition to the basic training, BSCAH also offers a Diploma/BSc taught in conjunction with the University of Birmingham. Applications are invited from those registered with the GMC, GDC, NMC, HCPC, Clinical Psychologists, and University-based Academics.

Two: The National College of Hypnosis and Psychotherapy
The National College of Hypnosis and Psychotherapy delineates itself from other hypnotherapy organizations, stating, “It is our policy that we will only align ourselves with organizations which have meaningful and verifiable means of accreditation. The profession has many organizations that will give you a certificate for a fee. We, as one of the oldest schools of professional hypnosis and psychotherapy, believe that we should take a leadership position with this and not support bodies which have only been created to give out meaningless credentials and to turn a profit for its owners.”
The National College has a direct arrangement with Bath Spa University.

The practice of hypnotherapy has always lacked a standard of educational requirements. In fact, you can take an online course on Udemy and become a Certified clinical hypnotherapist for £9.95. If that is out of your price range ( Joke!!!! ) then just print yourself a Certificate and open your own office. 
The bottom line is the quality of education being presented.

If you seek a genuine education that provides evidence-based curriculum, based on the most recent peer-reviewed research, and which includes clinical practice/experience, look into the educators’ professional affiliations, experience, and clinical background.
