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 Board.

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 ( 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 in January) or as a zoom-only version (usually 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.

Applicants who do not yet meet the entry requirements of The London Diploma may wish to undertake the LDPRT-endorsed part-time (
London Foundation Certificate in Counselling & Psychotherapy (LFCCP)
which has a dedicated psychosexual and relationship module within the curriculum.
LFCCP can act as a conduit to the two-year training.

    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 2023-2025 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 2022

We continue to be the "leading training provider" in the field, having pioneered since our earliest incarnation in 1990 support for a wide range of expressions of human sexuality. 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.

From 2022 we are, in addition to our annual research days for current and past students, adding two further days to our timetable bringing the total number of teaching days to 38+ days. These two days are given over to the particular contributions and challenges "trans" and non-binary gender identities may offer, as well as alternative models for sex and relationships. We will critically examine heteronormativity, hetero, bi and homosexualities and kink. GSRD and cultural inclusivity are fully integrated into our curriculum.

Due to the high volume of applications we are now no longer accepting applications for January 2023 unless potential students wish to be placed on a reserve list.

We are still accepting applications for the zoom version of the course which starts in June 2023. Interviews for admission to the 2023 zoom course will take place on June 3rd 2022.
