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

The cost of rehab in the UK depends on one question more than any other: what level of care does the person actually need? NHS and council-funded services are free but mostly community-based, with limited residential places. Private residential rehab is charged per week, and the fee moves with the level of medical and therapeutic care involved. This guide explains both routes, what drives private fees, what insurance covers, and the questions worth asking before paying anyone.

Rehab is often considered during a crisis, when families feel pressure to decide quickly. A clear assessment helps avoid both under-treating a serious problem and paying for more intensity 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: the short answer

There is no single price for rehab in the UK, because cost follows the care:

• NHS and local-authority drug and alcohol services are free to the person using them. Most provision is community-based; funded residential places exist but are limited and slow to access.
• Private outpatient treatment and day programmes cost less than residential care, because there is no accommodation or round-the-clock staffing.
• Private residential rehab is charged per week. The weekly fee varies widely between providers with the level of clinical care, whether a medically supervised detox is included, and the length of stay.

Because the figure moves so much with clinical need, a quoted "from" price tells you very little on its own. The only accurate number comes from an assessment of what care is actually required. If you want a real figure for your situation, the quickest route is a clinical assessment, or contact us to talk through fees directly.

Comparing the options

• Route: NHS / council services · What you pay: Free · Typical waiting: Varies by area; community support is usually quickest, funded residential places are slow and case-by-case · What it involves: Assessment, key working, community detox, group and recovery support
• Route: Private outpatient · What you pay: Charged per session or programme · Typical waiting: Usually days · What it involves: Therapy and addiction support while living at home; suits stable, lower-risk situations
• Route: Private day programme · What you pay: Charged per programme · Typical waiting: Usually days · What it involves: Structured daily therapy with evenings at home; a middle level of intensity
• Route: Private residential rehab · What you pay: Charged per week · Typical waiting: Often immediate · What it involves: Accommodation, detox where needed, daily therapy, psychiatric input, family work, aftercare planning

Is there free rehab on the NHS?

Yes, some of it, 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 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 slow and difficult to secure one. It is worth exploring, with realistic expectations.

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 NHS options first, especially if cost is the deciding factor. If the NHS route is not available in the form, timeframe, or intensity you need, and you are able to fund it, that is when private care like ours makes sense.

What drives the cost of private rehab

When you compare private providers, you are mostly comparing weekly fees for residential care. Understand a quote through these factors rather than a headline figure:

• Level of care. Outpatient and day care cost less than residential treatment, which includes accommodation, meals, and on-site clinical staffing throughout the week.
• Detox. A medically supervised detox at the start of treatment adds assessment, monitoring, prescribing, and clinical oversight, and affects the cost.
• Clinical intensity. More frequent one-to-one therapy, psychiatric review, and care for co-occurring mental health needs (trauma, eating disorders, dual diagnosis) increase the resourcing behind the fee.
• Length of stay. Residential rehab is priced per week, so a longer admission costs more overall. Clinical need, not a fixed package, should set the length; for some people a longer stay is the safer and more effective choice.
• Location and setting. Fees differ by clinic and region, and by the environment the clinic provides.

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.

What is usually included

A private residential package normally covers 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 clearly before admission, and it is reasonable to ask what costs extra.

Why the cheapest option is not always the safest

A lower price is attractive, especially when families are frightened and money is 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 can leave the most important risks untreated. Equally, the most expensive option is not automatically the best. Good treatment is clinically proportionate, transparent about what is included, and matched to the person's actual risk.

Does insurance cover rehab?

Sometimes, and it is always worth checking before assuming you must self-fund. In practice:

• Cover depends on the policy, not the provider. Addiction treatment is included in some UK private medical insurance policies and excluded or capped in others; mental health cover and addiction cover are often separate clauses.
• Insurers usually require pre-authorisation. That generally means a diagnosis, a clinician's confirmation that treatment is medically necessary, and agreement on the level and length of care before admission.
• The clinic must usually be recognised by the insurer. Ask the clinic which insurers it works with, and ask the insurer for its recognised providers.
• Expect limits. Policies may cap the number of funded days, cover detox but not the full residential stay, or require reviews during treatment.

Beyond insurance, people fund treatment privately, through family contributions, employer support, or a combination. PROMIS can discuss the options after assessment and help families understand what level of care is being recommended and why.

Questions to ask before paying for rehab

• What assessment happens before admission, and who carries it out?
• 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 and treated?
• What qualifications and clinical governance sit behind the programme?
• How is family involvement handled?
• What aftercare is included or recommended, and for how long?
• What happens if the person wants to leave early or needs a higher level of support?
• What exactly does the weekly fee include, and what costs extra?

Getting a clear recommendation

The most useful first step is a confidential clinical assessment. It clarifies whether residential treatment, day treatment, outpatient therapy, detox, psychiatric input, or family support is appropriate. Only then does cost become a meaningful conversation.

PROMIS is a mental health and addiction clinic with weekly psychiatric input, running two small residential 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.

FAQs about rehab costs

How much does private rehab cost per week in the UK?

Private residential rehab is charged per week, and the fee varies widely between providers with the level of clinical care, whether detox is included, and the setting. No single number is honest for everyone, which is why PROMIS prices after a clinical assessment rather than quoting a flat rate online.

Is rehab free on the NHS?

NHS and council-funded drug and alcohol services are free, and mostly community-based. The NHS funds a small number of residential places case by case through local authority panels, which are slow and hard to secure. Community support is free and much quicker to access.

Does private health insurance pay for rehab?

Some UK policies cover addiction treatment, usually with pre-authorisation, a medical-necessity requirement, and limits on days or level of care. Check your policy's mental health and addiction clauses and ask the clinic which insurers it works with.

Why don't clinics publish exact prices?

Because the fee depends on clinical need: detox or no detox, the intensity of psychiatric and therapeutic input, and length of stay. A fixed headline price either overcharges people who need less or under-resources people who need more. A real quote follows an assessment.

What should be included in the cost of rehab?

Assessment, individual and group therapy, medical and psychiatric review, accommodation and meals in residential care, family involvement, relapse prevention, and aftercare planning. Ask any provider exactly what the fee covers and what costs extra.
