How Much Does Rehab Cost in the UK? (2026 Guide)

Introduction

The cost of private rehab in the UK varies widely. The right question is not only how much rehab costs, but what level of care is clinically appropriate, what is included, and whether the programme can safely meet the person's needs.

Rehab is often considered during a crisis, when families feel under pressure to make a decision quickly. A clear assessment can help avoid both under-treating a serious problem and paying for a level of care that is more intensive than the person needs.

"If someone is at immediate risk from alcohol withdrawal, overdose, self-harm, psychosis, violence, or severe confusion, seek urgent medical help before comparing treatment options."

How much does rehab cost in the UK?

There is no single price for rehab in the UK, because cost depends on the type of care you need and where you have it.

Free routes exist. NHS and NHS-funded community drug and alcohol services do not charge for treatment, and local authority funded services are also free to the person using them. These are usually community based (outpatient, structured day support, community detox) rather than residential, and availability and waiting times vary by area. The NHS is the right first stop for anyone who cannot fund private care.

Private residential rehab is usually charged per week, and the weekly fee varies widely between providers depending on the level of clinical care, the length of stay and whether a medically supervised detox is included. Because the figure moves so much with clinical need, a quoted "from" price tells you very little on its own. The honest answer to "how much will rehab cost me" is: it depends on the care you actually need, and the only accurate number comes from a clinical assessment.

If you want a real figure for your situation rather than a range, the quickest route is a clinical assessment, which establishes the level of care required before any cost is discussed. You can also contact us to talk through fees directly.

What affects what you pay (see the detail below): level of care (outpatient, day care or residential), length of stay, whether a medically supervised detox is needed, the intensity of psychiatric and therapeutic input, and location. Each of these is covered in more depth in the next section.

Is there free rehab on the NHS?

Yes, some of it is, and it is the right first stop for anyone who cannot fund private care. NHS and council funded drug and alcohol services are free to the person using them, and most of what they provide is community based: assessment, key working, community detox and recovery support. You can self refer to most local services or be referred by your GP.

The NHS does also fund some residential and inpatient rehab, so it is not true that funded residential treatment does not exist. But it is not booked directly. A residential place is funded case by case through a local authority panel, the criteria are strict, the number of funded places is small, and in practice many people find it genuinely difficult and slow to secure one. It is well worth exploring, but go in with realistic expectations about how hard a funded residential place can be to access.

None of this means private care is "better treatment for money". What private treatment offers is faster access, a residential setting, and a higher intensity of one to one and psychiatric input than most community services can provide. Our honest advice is to explore your NHS options first, especially if cost is the deciding factor. But if you would prefer private treatment, or you have looked at the NHS route and found that it is not available in the form, timeframe, or intensity you are looking for, and you are able to fund it, that is exactly when private care like ours makes sense. A good next step either way is a clinical assessment, or a confidential conversation with our team.

What affects the cost of rehab?

Private rehab pricing depends on the type of treatment, length of stay, accommodation, clinical staffing, medical complexity, psychiatric input, detox needs, therapy intensity, family work, aftercare, and whether treatment is residential, day patient, or outpatient.

* Residential treatment usually costs more because it includes accommodation, staffing, meals, therapeutic structure, and support throughout the week.

* Medically managed detox can add cost because it requires assessment, monitoring, medication planning, and clinical oversight.

* Complex presentations may require psychiatric review, trauma-informed therapy, eating disorder support, or dual diagnosis care.

* Longer treatment usually costs more overall, but a longer stay may be safer or more effective for some people.

* Lower-cost programmes may offer less clinical intensity, less individual therapy, or less medical support.

Residential rehab, day treatment and outpatient care

Residential rehab is usually considered when the person needs distance from triggers, detox support, intensive therapy, or a safe environment away from home. It may be appropriate where relapse has been repeated, mental health risk is high, or the home environment is unstable.

Day treatment can provide structured therapy while the person returns home in the evening. Outpatient treatment may be suitable when the person is medically stable, has support at home, and can engage reliably with appointments.

PROMIS offers different levels of addiction treatment because cost should follow clinical need, not the other way around.

What is usually included?

A private treatment package may include assessment, individual therapy, group therapy, medical review, psychiatric input where needed, family meetings, relapse prevention planning, accommodation, meals, therapeutic activities, and aftercare planning. The exact offer should be explained before admission.

It is reasonable to ask what is included, what costs extra, how often the person will see a therapist, whether detox is available, how psychiatric care is arranged, what happens in a crisis, and what support is offered after discharge.

How rehab is priced (what to expect)

When you compare private providers, you are mostly comparing weekly fees for residential care. Use these factors, not a single headline figure, to understand a quote:

* Level of care: outpatient and day care cost less than residential inpatient care, because residential includes accommodation, meals and on-site clinical staffing.

* Length of stay: residential rehab is usually priced per week, so a longer admission costs more; clinical need, not a fixed package, should set the length.

* Detox: if you need a medically supervised detox at the start of treatment, that adds clinical and prescribing input and affects the cost.

* Clinical intensity: more frequent one to one therapy, psychiatric review and complex co-occurring mental health needs increase the resourcing behind your care.

* Location: fees differ by clinic and region.

Because these vary so much from person to person, PROMIS does not quote a flat price online. A clinical assessment establishes what level of care you need, and the fee follows from that. To discuss fees for your situation, contact us.

Why the cheapest option is not always the safest

A lower price can be attractive, especially when families are frightened and finances are stretched. But addiction treatment is healthcare. If a person needs detox, psychiatric assessment, trauma support, eating disorder care, or a protected environment, a cheaper but under-resourced setting may leave important risks untreated.

Equally, the most expensive option is not automatically the best. Good treatment should be clinically proportionate, transparent, ethical, and matched to the person's risk and goals.

Questions to ask before paying for rehab

* What assessment is carried out before admission?

* Is detox available, and who oversees it medically?

* How much individual therapy is included each week?

* How are depression, anxiety, trauma, eating disorders, or other substances assessed?

* What qualifications and clinical governance sit behind the programme?

* How is family involvement handled?

* What aftercare is included or recommended?

* What happens if the person wants to leave early or needs a higher level of support?

Paying for rehab

Some people pay privately. Others may use private medical insurance, employer support, family contributions, or a combination of resources. Insurance cover varies and may depend on diagnosis, policy terms, medical necessity, and whether the provider is recognised by the insurer.

PROMIS can discuss available treatment options after assessment and help families understand what level of care is being recommended and why.

Getting a clear recommendation

The most useful first step is a confidential clinical assessment. This helps clarify whether residential treatment, day treatment, outpatient therapy, detox, psychiatric input, or family support is appropriate.

PROMIS is a mental health and addiction clinic with weekly psychiatric input, running two small inpatient clinics (Hay Farm in Kent and Kendrick Mews in London) alongside outpatient and day care. Care is matched to clinical need rather than to a fixed package.

Rehab is a significant financial and emotional decision. The aim should be to choose the safest, most clinically suitable treatment at the right level of intensity, with a plan for what happens after the first phase of care ends.
