July 2024

This two-year part time modular training programme, is accredited by the College of Sexual and Relationship Therapists (COSRT), and by Middlesex University, as well as by the National Council for Integrative Psychotherapists (NCIP) and the National Counselling Society (NCS) and provides a potential pathway into the Accredited Register (AR) of the Professional Standards Authority (PSA).

Graduates may register with COSRT immediately upon having met the Diploma requirements and may progress to accreditation after fulfilling further requirements of COSRT or other bodies. This may involve additional training with organisations such as the NAOS Institute, as well as more supervised practice..

Successful completion of the two year London Diploma taken together with the one-year Advanced Diploma in Relationship Psychotherapy (www.naos-institute.com) is in total fulfilment of the requirements for NCS accreditation and the Accredited Register of the Professional Standards Board (PSB). We are the only psychosexual and relationship therapy training in the UK accredited to provide this pathway.

The London Diploma (UK) may be taken as an in-class, face to face teaching programme (usually commencing in January) or as a zoom-only version (usually commencing in June) for students unable to travel to London.

The course originally ran from one of London's teaching hospitals from 1990 until 2005 and has since taken its current form. We focus on applying Integrative ways of working with psychosexual and relationship therapy issues. Our tutors bring their own professional background in psychotherapy, medicine, law, ethics or related fields, as well as a range of modalities such as Gestalt, CBT, Attachment Theory, Transactional Analysis, Existential and Transpersonal, amongst others. Students are encouraged to develop their idiosyncratic way of working (P. Clarkson, 2010).

We acknowledge the multi-faceted nature of society; we are dedicated to professional practice based on knowledge, integrity, respect, challenge and the life affirming nature of sexuality and relationships in all their forms. Our faculty is comprised of highly experienced, senior practitioners representing diverse cultural, sexual and relationship identities.

    In line with COSRT's core curriculum , LDPRT students will gain comprehensive knowledge and understanding of:
  • psychosexual development
  • the anatomy and physiology of sexual difficulties, inclusive of organic and non-organic issues
  • relational issues and stages of development within the lifespan of couples and relationships
  • dealing with conflict, encompassing different models of relationship,and appreciative models of conflict and differentiation

Also included in the course curriculum are clinical assessments and diagnostic categories , treatment strategies and tools working with diversity : "Imago" survivors and perpetrators of sexual abuse, the environmental and cultural impact on sex and couples, forensic issues, philosophies and frameworks of integration.

For further details see the 2025-2027 course information sheet.

We maintain strong links with a variety of placement providers throughout the UK, in Europe and further afield.
The course equips participants to work in either the statutory or voluntary sectors, or in private practice.

Our Curriculum in 2024

Having been independently assessed as the "leading training provider" in the field and having supported a wide range of expressions of human sexuality over 3 decades now, we continue to challenge a "one size fits all" approach to working with relationships, and welcome all student population groups - worldwide - into our programme. Our faculty couldn't be more diverse and are only matched by our student body representing to date 40 different cultural identities. We challenge the divide between 'mainstream' and erotically marginalised population groups and aim to serve all and hence subscribe to an expansive view of GSRD.

From 2023 onwards we have added a range of visiting tutors to our faculty each bringing their own expertise to our curriculum; these are available mid week via remote-access outside of our usual teaching times..

Applications for LDPRT courses start in the year preceding the start date usually from March. As courses often fill at least a year in advance we recommed early application.

Both the 2025 in-room and the 2025 Zoom courses are now full.

Any applications will now be placed on a reserve list.

Please note that our courses tend to be full with waiting lists a year before commencement.
