Private residential rehab in London costs roughly £4,200 to £21,800+ for a 28-day programme, depending on the clinic, the level of medical detox involved, and how much you’re paying for luxury rather than care.
That’s a wide range, and the number you actually pay comes down to a few specific things. This guide breaks them all down (with real, named London prices rather than vague “from £X” figures) and explains how to fund treatment if you can’t pay it all upfront.
We run a residential rehab in Clapham, Zone 2 South West London, so these are the questions we answer on the phone every day. We’ve kept the numbers honest, including where we sit against the well-known names.
How much does rehab cost in London?
A 28-day stay in a private London residential rehab typically costs from around £4,200 at the budget end to over £21,000 at the luxury end. Smaller clinics often price per week instead, our Clapham centre is £4,250 a week, with a two-week minimum stay (£8,500). Outpatient treatment, where you live at home and attend sessions, is cheaper at roughly £1,000 to £3,000 for a comparable period.
The single biggest driver of the headline number is whether the price includes a medically supervised detox.
A detox needs doctors and nurses on site, which costs more than therapy alone, so programmes that bundle it sit higher than “therapy-only” residential stays.
London rehab prices in 2026: what you'll actually pay
Here’s where the well-known London and national providers sit for a 28-day residential programme, based on their own published pricing as of June 2026.
| Provider | Residential price | What’s included |
|---|---|---|
| PCP London (Clapham) | £4,250/week – £8,500 for the 2-week minimum stay | Medically supervised detox, full therapy programme, aftercare |
| Priory “Flourish” | from £4,200 (28 days) | Residential treatment without detox |
| Gladstones (London) | £5,000-£15,000+ (28 days) | Detox, therapy, aftercare |
| Priory “Transform 28” | £21,813 (28 days) | Detox, daily therapy, 12 months aftercare |
PCP London is priced per week (£4,250) with a two-week minimum stay, so you’re not forced into a fixed 28-day package. For reference, a full 28-day stay at our sister residential clinics is £12,500 (Luton) to £14,500 (Cardiff).
Two things jump out of that table.
First, the gap between the floor and the ceiling is enormous, more than £17,000 between the cheapest and most expensive 28-day options for what is, clinically, a similar length of stay.
Second, the cheapest Priory option (£4,200) excludes detox, while our Clapham programme (£4,250 a week) includes it. Always check what the headline price actually covers.
Why does rehab cost more in London than the rest of the UK?
London is the most expensive rehab market in the country, and three forces push the price up.
Real estate. A residential clinic needs a safe, comfortable, well-located building. London property and rent cost far more than equivalent space in the Midlands or Wales, and that flows straight into the fee.
Clinical staffing. Round-the-clock doctors, nurses and therapists cost more to employ in London. Smaller, higher-ratio clinics (which give you more one-to-one time) carry higher staffing costs per client.
Demand for discretion. London has a large population of professionals who need confidential treatment close to work. That demand supports premium pricing at the top of the market.
None of this means you have to pay top-of-market rates. It means you should understand what you’re paying for.
How much is a 28-day stay at the Priory?
The Priory’s flagship programme, Transform 28, costs £21,813 for 28 days. That price includes a medically supervised detox, a daily therapy programme, and 12 months of aftercare.
The Priory is the most recognisable name in UK rehab, and its pricing sits at the top of the London market. It’s a genuine, high-quality service but the brand premium is real, and you are not choosing between “the Priory” and “nothing.”
What is a cheaper alternative to the Priory?
There are several CQC-regulated London clinics offering the same core clinical elements (medical detox, structured therapy, aftercare) at a fraction of the price.
Our Clapham centre charges £4,250 a week, with a two-week minimum stay (£8,500), and every programme includes a medically supervised detox.
The difference is rarely clinical quality. It’s the size of the estate, the brand, and the level of luxury extras.
A smaller 9-bed clinic can offer a higher counsellor-to-client ratio than a large hospital, at a lower price, precisely because there’s no premium estate to fund.
Affordable vs luxury London rehab: what changes with the price?
As you move up the price scale, what you’re buying changes in predictable ways.
- Clinical care (detox, therapy, medical cover) is broadly comparable across all reputable CQC-regulated clinics as this is the part that actually drives recovery.
- Accommodation moves from comfortable en-suite rooms to hotel-style luxury suites.
- Extras like private chefs, spa facilities, equine therapy and designer interiors appear at the top end.
- Privacy and exclusivity fewer clients, more seclusion – command a premium.
Paying £21,000 instead of £5,000 buys you a more luxurious experience, not necessarily better clinical outcomes. For most people, a mid-range CQC-regulated clinic delivers the treatment that matters.
What's included in a typical London rehab fee and what isn't
A clear, all-inclusive fee should cover your accommodation, all meals, the medically supervised detox, your full therapy programme, and an aftercare plan.
At our Clapham centre, that’s exactly how the fee works with one figure and no surprises.
Watch for costs that sit outside the headline price at some clinics:
- Detox charged as a separate add-on (as with some “therapy-only” residential packages)
- Extended stays beyond the booked programme, billed per extra day or week
- Secondary treatment or a step-down programme after primary care
- Travel and transfers to and from the clinic
- Private medical extras not covered by the core fee
Always ask for the fee in writing and confirm precisely what it includes before you commit.
How to pay for rehab in London
Most people don’t pay a single lump sum. There are several routes, and they’re often combined.
Self-funding with a payment plan. The most common route. Many clinics, including ours, let you spread the cost rather than pay it all upfront, speak to our admissions team about how this works.
Private medical insurance. Bupa, AXA Health, Vitality and WPA all fund addiction treatment under some policies. Check whether yours includes inpatient mental health and addiction cover, and whether your chosen clinic is recognised by the insurer.
NHS-funded placements. Rare, and decided case by case by your local authority after community treatment has been tried. If cost is the barrier, start by reading our guide to free drug and alcohol rehab in London, it explains the NHS and council routes in full.
Family funding. Families frequently fund or co-fund treatment, particularly where getting someone into care quickly is the priority.
Is paying for private rehab worth it?
For someone whose drinking or drug use is medically risky, the value isn’t really in luxury, it’s in speed and safety. Free routes can take weeks or months; private admission can happen within 24 hours.
A medically supervised detox also removes a genuine danger. Stopping alcohol suddenly when you’re physically dependent can trigger seizures and delirium tremens, which is why a supervised alcohol detox matters more than any spa facility.
The question worth asking isn’t “what’s the cheapest clinic” or “what’s the most expensive.” It’s “what’s the lowest price that still includes a proper medical detox, real therapy and aftercare, in a CQC-regulated setting?” That’s where the value sits.
