How to Become a Psychosexual and Relationship Therapist in the UK

If you are researching how to become a psychosexual therapist in the UK, the first thing to understand is that this is normally a post-qualifying specialism. Psychosexual and relationship therapists work with the complex interaction between sexual wellbeing, physical health, psychological experience, identity, intimacy and relationships. The work requires substantially more than an interest in sexology: it demands an established therapeutic foundation, specialist clinical training, supervised practice and sustained reflective development.

This guide explains the principal stages of the UK training route, what to look for in a course and how the Institute of Psychosexual Psychotherapy (IoPP) supports qualified therapists to develop specialist practice.

What does a psychosexual and relationship therapist do?

Psychosexual and relationship therapists support individuals and partners with concerns that may include sexual function, desire and arousal, sexual pain, shame, intimacy, communication, relationship distress, gender and sexual diversity, compulsive sexual behaviour and the effects of trauma, health conditions or medication on sexual wellbeing.

Good practice is biopsychosocial and relational. It considers the body and sexual medicine alongside a person’s psychological experience, social context, relationships, culture and identity. Therapists therefore need a broad clinical framework and the ability to work collaboratively, ethically and without imposing assumptions about what a healthy sexuality or relationship should look like.

1. Begin with a recognised professional therapy qualification

Specialist psychosexual training is not generally intended to replace core counselling, psychotherapy or psychology training. Applicants would usually already be qualified to practise as a talk therapist and be registered or accredited with an appropriate professional body.

At IoPP, the qualifying diploma is designed for practitioners such as counsellors, psychotherapists and practitioner psychologists who hold appropriate professional registration. Relevant bodies may include ACC, BABCP, BACP, BPC, COSCA, HCPC, UKCP and UKAHPP. International applicants need to demonstrate equivalent professional standing in the country where they are qualified or practise.

This starting point matters because trainees will be developing a specialism while drawing on existing competencies in assessment, contracting, safeguarding, ethics, boundaries, therapeutic relationships and the management of clinical risk.

2. Choose an appropriately accredited specialist course

The College of Sexual and Relationship Therapists (COSRT) is the UK professional body dedicated to psychosexual and relationship therapies. COSRT assesses external training against standards covering course governance, entry requirements, learning outcomes, teaching quality, clinical placements, supervision and professional development.

Prospective students should distinguish between a short introductory course, a thematic qualification and a Specialised Practice Qualification designed to prepare therapists for specialist practice. COSRT describes its accredited Psychosexual and Relationship Therapy Level 7 courses as covering the integrated discipline of psychosexual and relationship therapy, with graduation providing entry to its Psychosexual and Relationship Therapy and Relationship Therapy registers.

IoPP’s Level 7 Diploma in Psychosexual and Relationship Psychotherapy is accredited by COSRT as a Specialised Practice Qualification. You can also verify the programme on the official COSRT course listing.

3. Develop specialist knowledge and clinical skills

A credible qualifying programme should integrate theory, skills practice and clinical application. Areas of study are likely to include:

• sexual anatomy, physiology, medicine and common sexual function concerns;
• assessment and biopsychosocial formulation;
• psychosexual treatment models and evidence-informed interventions;
• relationship, partner and couple therapy;
• gender, sexuality and relationship diversity;
• trauma-informed and anti-oppressive practice;
• mental health, medication, disability and physical health;
• compulsive sexual behaviour, chemsex and other complex presentations;
• ethics, safeguarding, professional boundaries and clinical risk; and
• reflexivity and the use of self in the therapeutic relationship.

IoPP’s pluralistic philosophy recognises that no single model suits every person or every situation. Students are encouraged to integrate ideas from humanistic, psychodynamic, systemic, cognitive-behavioural and other evidence-informed traditions while remaining responsive to each client’s circumstances and autonomy.

4. Complete supervised specialist clinical practice

Learning about psychosexual therapy is not the same as learning to practise it safely. A qualifying route must include specialist clinical work under appropriate supervision.

IoPP students complete a 150-hour clinical training placement and receive supervision at a ratio of at least one supervision hour for every six hours of clinical practice. Placement and supervision arrangements must meet both course and COSRT requirements. IoPP can help students identify suitable opportunities through its network and provider links, but each student remains responsible for applying for and securing an approved placement.

Qualified therapists may sometimes be able to undertake approved training work within an existing service or private practice, provided the setting, governance, insurance or organisational indemnity, supervision and client work are suitable. These arrangements require approval rather than being assumed automatically.

5. Commit to personal and professional development

Psychosexual and relationship work can engage deeply personal material for both client and practitioner. High-quality training therefore includes structured reflection, personal development and attention to the therapist’s own assumptions, responses and relational patterns.

IoPP’s diploma requires personal and professional development activity, including personal therapy with a suitably qualified practitioner. Reflective process groups are embedded within the teaching programme. Their purpose is not simply to acquire more techniques, but to help therapists develop the self-awareness, authenticity and reflexivity needed for ethically complex encounters.

6. Understand registration and professional accountability

Counselling and psychotherapy include occupations that are not regulated by statute in the same way as medicine or nursing. The Professional Standards Authority explains the role of voluntary registers and its Accredited Registers programme in promoting public protection.

Before enrolling, check exactly what a course is accredited to provide and what successful completion allows you to apply for. Also consider the professional requirements that continue after qualification, including ethical codes, ongoing supervision, continuing professional development, complaints procedures and appropriate professional indemnity or employer cover.

International students should additionally check the laws, registration arrangements and insurance requirements applying in every country where they intend to work. A UK qualification does not override another jurisdiction’s rules.

Questions to ask a training provider

Before committing to a course, ask:

• Is this a qualifying specialist programme or a continuing professional development course?
• Who accredits it, and can I verify that independently?
• What professional qualification and registration do I need before applying?
• How many clinical placement hours are required?
• What are the supervision requirements and additional costs?
• Who teaches the biomedical, psychotherapeutic and relationship components?
• How are live skills, ethical practice and clinical competence assessed?
• What personal therapy or reflective-development requirements apply?
• What support is available when seeking a placement?
• What does graduation permit me to do or apply for?

The IoPP training route

The Level 7 Diploma in Psychosexual and Relationship Psychotherapy is IoPP’s COSRT-accredited qualifying programme for already-qualified talk therapists. It is delivered part-time over two years and combines live teaching, practical skills development, reflective process work and a 150-hour specialist clinical placement.

Students can study through the published online or in-person attendance routes. Small cohorts support discussion, skills practice and contact with an interdisciplinary teaching faculty spanning psychotherapy, relationship therapy, psychology and sexual medicine.

Once qualified, therapists who want to deepen complex clinical and research practice can explore IoPP’s Level 7 Advanced Diploma in Psychotherapy Practice.

Take the next step

Choosing specialist training is a significant professional decision. Review the curriculum, accreditation, placement requirements, professional outcomes and total costs carefully, then speak with the provider about how your existing qualification and practice context fit the route.
