My Training
My initial training was as a hypno-psychotherapist, This is a psychotherapist who has specialised in the use of the hypnotic medium. I am therefore trained beyond the use, solely of hypnosis and related techniques.
I primarily trained at the National College of Hypnosis and Psychotherapy. The National College is the only institution of its kind externally accredited by the British Accreditation Council for Independent Further and Higher Education. The training I underwent was lengthy and thorough and is one of only a few hypnotherapy training's that allow for UKCP membership.
I am a full member of the NRHP who are in turn members of the hypno-psychotherapy section of the UKCP.

Other Trainings

Certified HypnoFertility Practitioner with Lyndsi Eastburn and the HypnoBirthing Institute

I am currently undergoing psychotherapy training in psychoanalysis and analytical psychotherapy with the Association of Independent Psychotherapists in London.

Being a therapist is not just about qualifications and experience but it is also about the state of mind of the therapist. I believe that a therapist needs to take their own personal work very seriously. It is important that they have worked on themselves in order to understand what they are trying to help a client with, it is also important that as much as possible they are are aware of and able to keep in check their own unconscious desires and motivations to stop them from aversely affecting their work with clients.
To this end I undertake 3 times weekly personal analysis and fortnightly supervision. I meditate daily and work actively and seriously with various groups in the exploration of the potential for human experience and the expansion of consciousness.

Finding a Therapist
Having said all that, a recognised qualification does not necessarily mean a good therapist, and a good therapist may well have no recognised qualifications!

The best thing to do when looking for a therapist is to check out  where they trained and for how long, and then call them up and have a chat. You may wish not to commit there and then to working with the therapist but to leave yourself some time to mull it over.
Be wary of anyone offering guaranteed cures, the human mind is so utterly complex that no therapy or therapist can guarantee that the work will be successful. To do so is unethical.

A word about qualifications and organisations.
Currently in the UK there are no government regulations surrounding hypnotherapy. This means that you could award yourself an advanced diploma in hypnotherapy and start practicing today! Does that sound scary? ...
There are also many organisations, associations and registers that hypnotherapists can belong to that may or may not claim to be the central or governing body for the UK. Unfortunately there is no such thing, they are all volunteer organisations with differing agendas and differing requirements for their members.

Shortly the European laws come into effect in the UK and the area of psychotherapy looks set to become regulated by the government.
Unfortunately it now does not seem likely that Hypnotherapy is going to be regulated in the same way. This means that for the time being the general public need to be very wary of what ‘professional’ hypnotherapist they undertake work with.
The UKCP is a psychotherapy organisation that covers hypnotherapy. It is approved by the government and its members will be allowed to practice as psychotherapists when the EU regulations come into effect.
The UKCP have a Hypno-Psychotherapy section and currently there are four member organisations, the National College and the NRHP being two of them
