Private Drug & Alcohol Rehab in London

Looking for private rehab in London?

If you are searching for private drug or alcohol rehab in London, you are usually trying to do one of two things: get a place quickly for yourself, or get help for someone you are worried about. Promis runs a small private inpatient clinic in central London, at Kendrick Mews in South Kensington, that provides residential drug and alcohol rehab alongside treatment for mental health conditions.

This page explains what rehab at our London clinic involves, how to start, and where it fits in the wider service. The first step for everyone is the same: a clinical assessment that decides what kind of treatment is actually right for you. There is no need to know that answer before you call.

One thing to be clear about from the start. We are not a rehab-only clinic. Kendrick Mews treats mental health difficulties such as depression, anxiety and trauma as well as addiction, and roughly half of the people who come to Promis come for mental health treatment rather than addiction. More on that below, because it matters for getting the right help.

Rehab at our London clinic (Kendrick Mews)

Our London rehab is residential. You stay at the Kendrick Mews clinic in South Kensington for the duration of your treatment, rather than travelling in for appointments. It is a small, low-census clinic: we deliberately limit numbers so the team can know each person in depth and adjust treatment as things change, rather than running everyone through a fixed timetable.

Care is formulation-led. That means treatment starts from a clinical understanding of why the addiction developed and what is keeping it going, including any mental health difficulties underneath it, rather than from a single fixed programme. The formulation acts as the central map that guides the therapeutic work, and it is reviewed as the team sees how you respond.

The clinic has weekly psychiatric input. A psychiatrist reviews medication, withdrawal management and any co-occurring conditions, working alongside the therapy team. Promis is a voluntary residential service, not a psychiatrist-led acute unit, and the psychiatric input exists to keep treatment safe and properly coordinated.

Where withdrawal needs to be managed, we provide medically supervised detox. Detox from alcohol or some drugs can be uncomfortable and, for heavier or long-standing dependence, genuinely dangerous: unmanaged alcohol withdrawal can involve seizures and delirium tremens and can be life-threatening (NICE CG100; NHS). Doing it under medical supervision, with the right medication at the right time, is what makes it safe. Not everyone needs a detox, and the assessment decides whether you do.

We are a mental health clinic too, not rehab-only

This is the part people searching for "rehab" often miss, so it is worth saying plainly. The London clinic is a full mental health and addiction service. It treats conditions such as depression, anxiety, trauma and burnout, not only drug and alcohol problems. About half of the people who come to Promis come for mental health treatment rather than for addiction.

That matters for two reasons. First, addiction and mental health difficulties very often travel together. Someone arriving for alcohol rehab may also be carrying untreated depression or trauma, and treating one while ignoring the other tends not to hold. NICE is clear that coexisting mental illness and substance misuse should be treated together rather than in separate silos (NICE NG54). Because the same clinic and the same team handle both, that integrated work happens in one place.

Second, if what you actually need is mental health treatment rather than rehab, you are still in the right service. You do not have to fit yourself into an addiction label to be seen here. If you are not sure which applies to you, the assessment will help work that out, and you can read more about our mental health treatment or our addiction treatment to see how each side works.

What treatment involves

Treatment at the London clinic moves through clear stages, set by clinical need rather than a fixed package.

  • Assessment. Everything starts with a clinical assessment. This establishes what is going on, how severe any dependence is, what withdrawal risk looks like, and whether residential treatment is the right setting. It is also where the formulation begins.
  • Detox, where needed. If withdrawal needs managing, medically supervised detox runs at the start of treatment, overseen by the prescribing clinician and supported by nursing staff, with psychiatric input on hand.
  • Residential therapy. The core of rehab is intensive one-to-one and group therapeutic work delivered through our primary care programme, addressing the drivers of the addiction and any co-occurring mental health difficulties together.
  • Aftercare and continuity. Treatment does not stop at discharge. We plan continuity of care so the work done in residential treatment is supported once you leave, which is the period when relapse risk is highest.

You can read more about how addiction treatment is structured on our drug addiction treatment hub, and about the residential programme itself in primary care.

An honest note on what we are and are not

Promis provides voluntary residential care. It is not an acute psychiatric unit, an emergency service or a Mental Health Act setting. For acute psychiatric admission we work with our sister hospital, Cardinal Clinic in Windsor.

If you or someone else is in immediate danger, or you are having thoughts of suicide or self-harm right now, this page is not the right route. Call 999 for an emergency, 111 for urgent NHS advice, or the Samaritans on 116 123 at any time. Once the immediate crisis is safe, an assessment can look at longer-term treatment.

Frequently asked questions

How much does drug rehab in London cost?

Cost depends on the length and type of treatment, which is set by the assessment, so we do not publish a single headline price. The honest answer is that we cannot quote a meaningful figure until we understand what your treatment actually needs to involve. Contact us and we will talk you through it clearly.

Do you treat both alcohol and drug addiction?

Yes. The London clinic treats alcohol dependence and drug addiction, including where someone is dependent on more than one substance, and where addiction sits alongside a mental health condition. See our addiction treatment hub for detail.

Is the London rehab inpatient or outpatient?

The rehab at Kendrick Mews is residential and inpatient: you stay at the clinic during treatment. Promis also offers outpatient and day care, and the assessment helps decide which setting fits.

Where in London is the clinic?

The clinic is at Kendrick Mews, South Kensington, in central London. Details are on the Kendrick Mews clinic page.

What if I need mental health treatment rather than rehab?

You are still in the right place. The clinic treats depression, anxiety, trauma and other conditions as well as addiction, and around half of our clients come for mental health treatment rather than addiction.
