Addiction Counselling at Harley Street

Addiction is not a failure of character. It is a solution — one that worked, for a while, and then stopped working but remained necessary. Understanding what the substance or behaviour was doing for the person, what it was providing or protecting against, is not a way of excusing it. It is the only way to address it at depth.

The Range of Addictions

The practice at Harley Street works with the full range of addictive presentations: alcohol, cocaine and other substances, gambling, sex and pornography addiction, food and eating compulsions, work addiction, prescription medication dependency. The specific substance or behaviour matters less than the underlying psychological structure — and that structure is usually similar across very different presentations.

Clinical Approach

Dr Jacquet trained in addiction treatment at the Hazelden Foundation, one of the most established addiction treatment centres in the world, and at Hope-One. His approach at Harley Street is integrative — drawing on psychodynamic, Jungian and cognitive models, adapted to the individual. The question guiding the work is not simply ‘how do we stop this?’ but ‘what has made this necessary, and what does it mean that it can no longer be given up?’

Discretion and Confidentiality

Many people seeking addiction counselling at Harley Street have professional or public positions in which confidentiality is essential. The practice maintains absolute discretion. No record of attendance is shared without explicit consent, and the work is conducted with the same degree of privacy that Harley Street has always offered.

Starting Treatment

An initial consultation at Harley Street or online is available without obligation. The first meeting is a conversation — to understand what is happening, to answer questions, and to decide whether this is the right place to continue.

Clinical Supervision — Promis Recovery Center & Cardinal Psychiatry

Philippe Jacquet served as clinical supervisor at the Promis Recovery Center — one of the United Kingdom’s most prestigious private addiction treatment clinics, with residential facilities in South Kensington, London and Hay Farm, Kent — for over five years. In this role, he supervised the entire clinical team, setting the therapeutic standards and overseeing the clinical work of the therapists responsible for some of the country’s most complex and high-profile addiction cases. He has also supervised the clinical team at the Cardinal Psychiatry Unit.

Clinical supervision at this level — responsible for the practice of a multidisciplinary team treating residential addiction patients — represents a form of accountability and expertise that most private practitioners never hold. It means that the clinicians treating patients at one of the UK’s most exclusive addiction facilities were themselves accountable to Dr Jacquet’s clinical judgment. That judgment is now available directly, in private practice.

Clinical Supervision at PROMIS Recovery Centre

For over five years, Philippe Jacquet has supervised the clinical team at PROMIS Recovery Centre — units in South Kensington, London and the Kent countryside. Founded in 1986, PROMIS is one of the UK’s oldest and most respected private addiction treatment facilities, recognised for nearly four decades of specialist residential treatment for alcohol and drug dependency, eating disorders and co-occurring mental health conditions.

Philippe Jacquet also supervises the clinical team at Cardinal Clinic — a private psychiatric hospital in Windsor rated Outstanding by the Care Quality Commission. Clinical supervision at institutions of this standing — providing professional oversight to specialist addiction and psychiatric teams — is a level of institutional involvement that very few private practitioners hold.

Lived Experience — Addiction and Eating Disorders

Philippe Jacquet brings to this work something that no qualification alone can provide: personal lived experience of both addiction and eating disorders. He is in long-term recovery. That experience — alongside Hazelden Foundation training, over 25 years of specialist clinical practice, and clinical supervision roles at PROMIS Recovery Centre and Cardinal Clinic — gives this work a depth of understanding that is genuinely rare in a practitioner at this level.

The Hazelden model has always recognised that lived experience in recovery is not incidental to clinical expertise — it is constitutive of it. A practitioner who has faced these difficulties personally brings a quality of understanding that goes beyond clinical knowledge: they know what is actually happening inside the experience, what the pull of the substance or behaviour feels like, what the moment of genuine recognition looks like, and what makes the difference between treatment that touches the real problem and treatment that does not.

This is not offered as biography. It is offered as the clinical context that explains why the work in this practice reaches where it does.
