Psychologist, Psychiatrist or Psychotherapist: What Is the Difference?

The terminology around mental health professionals is genuinely confusing, and not just for people who are new to it. The titles overlap in some areas, differ significantly in others, and the distinctions are not always clearly explained in the places people first look. It is entirely reasonable to be unsure which type of support is relevant for a given situation, or to have encountered all three terms without a clear sense of what separates them.

This guide sets out what each role actually involves, what training and registration each requires, and how to think about which type of practitioner might be most appropriate.

What is a psychiatrist?

A psychiatrist is a medical doctor who has completed a full medical degree before specialising in psychiatry through further postgraduate training. Because they are medically qualified, psychiatrists can diagnose mental health conditions in a formal clinical sense and prescribe medication as part of treatment. They are regulated by the General Medical Council (GMC) and sit within the medical profession rather than the psychological one.

Psychiatrists tend to work with presentations involving significant complexity or where medication is a likely part of the clinical picture. Conditions such as schizophrenia, severe bipolar disorder, psychosis, or depression that has not responded to other treatments are areas where psychiatric input is common. Many psychiatrists also provide psychotherapy, though the extent varies considerably depending on the individual and their training background. In the NHS, a GP referral is typically required. In private practice, psychiatrists can be accessed directly, though they may not work with the same level of complexity or risk as those within the NHS. Often clients who are presenting with significant risk of suicidality or self-harm are supported by psychiatrists within the NHS.  

What is a psychologist?

A Clinical or Counselling Psychologist has completed doctoral-level postgraduate training in psychological assessment and therapy, typically following an undergraduate psychology degree. In the UK, Clinical Psychologists train via the Doctorate in Clinical Psychology, a highly competitive programme that includes supervised clinical placements across a range of settings within the NHS. Unlike psychiatrists, psychologists in the UK cannot prescribe medication. Their work is psychological rather than medical: assessing and formulating difficulties, and delivering evidence-based therapeutic interventions.

Clinical and Counselling Psychologists are regulated by the Health and Care Professions Council (HCPC), and many hold membership of the British Psychological Society (BPS) as well. The range of presentations they work with is broad. Anxiety, depression, OCD, trauma, health anxiety, relationship difficulties, burnout: these are all areas where psychological therapy is typically the primary intervention rather than medication, and where a psychologist’s training is directly relevant. Psychologists can also offer diagnostic assessments, but these are typically done by a psychiatrist. 

What is a psychotherapist?

Psychotherapist is a broader term covering practitioners trained in talking therapies who have not completed a medical degree or doctoral-level psychology training. Training routes vary considerably, from two-year diploma programmes to four-year masters-level qualifications, depending on the therapeutic modality and institution. The title is not legally protected in the UK in the way that ‘Clinical Psychologist’ or ‘Counselling Psychologist’ is, which means registration with a recognised professional body is the meaningful marker when assessing a practitioner’s training and standards.

Accredited membership of the United Kingdom Council for Psychotherapy (UKCP) or the British Association for Counselling and Psychotherapy (BACP) indicates a significant level of training, supervised practice, and ongoing professional development. A skilled Integrative Psychotherapist brings together techniques from multiple therapeutic traditions, adapting the approach to what the individual needs rather than working within a single therapy model. The depth and quality of psychotherapeutic work varies considerably between practitioners, which makes professional registration and specialist experience important factors.

Which one do you actually need?

For most people seeking private therapy in London, the relevant distinction is between a psychologist and a psychotherapist rather than between either of those and a psychiatrist. Psychiatric involvement becomes relevant when medication, formal diagnosis for specific purposes, or assessment of more complex conditions is part of the picture. For the majority of presentations, including anxiety, depression, relationship difficulties, work stress, and most trauma-related difficulties, the question is which type of psychological practitioner is the better fit.

That distinction turns less on the title and more on the specific training, experience, and approach of the individual. A Clinical Psychologist or Counselling Psychologist with specialist trauma training may be the better choice over a generalist psychotherapist without specialist trauma training. An experienced Integrative Psychotherapist with deep expertise in a specific area may offer something a recently qualified psychologist cannot. The most useful question when making contact with a clinic is not which type of professional they employ, but what specific experience and training the recommended practitioner has for the difficulty you are presenting with.

What does London Bridge Therapy offer?

London Bridge Therapy is a specialist private psychology clinic. The team includes qualified Clinical Psychologists, Counselling Psychologists, and Integrative Psychotherapists, each registered with their relevant professional body and with specialist training in specific areas of clinical practice. The initial assessment is designed to identify clearly which type of support and which specific practitioner is most appropriate for what you are bringing. Every therapist within London Bridge Therapy is supported by a Consultant Clinical Psychologist, so every client has Consultant-level oversight into their care. 

Where psychiatric involvement is relevant, referral pathways are available. Where the presentation calls for psychological therapy, the right match within the team is established before any commitment to ongoing work.
