Free drug and alcohol treatment in London is real, and every borough has it. But almost all of it is outpatient, the provider changes depending on where you live, and a funded residential bed is genuinely hard to get.
This guide maps the whole free system for South London: what exists, who runs it, how to refer yourself today, and what to do when free isn’t fast enough.
We’ve written it from the other side of the fence. Our residential rehab in Zone 2 South West London sits in the middle of the Lambeth – Wandsworth – Southwark triangle, and a large share of the people who call us have already tried, or are weighing up, the free routes below.
Can you get free rehab in London?
Yes. Every London borough funds a free adult drug and alcohol service that you can self-refer into today, offering keyworker support, group programmes and prescribed medication.
Free residential rehab also exists (through council funding or charity beds) but places are limited and reserved for the highest-need cases.
That distinction matters more than anything else on this page. “Free rehab” in London almost always means community-based outpatient treatment: appointments you attend while living at home.
A funded bed in a residential clinic is the exception, not the rule. According to the National Drug Treatment Monitoring System (NDTMS), tens of thousands of Londoners are in structured treatment each year but only a small fraction of local authority addiction budgets goes to residential placements.
How free drug and alcohol services in London actually work
There is no single “London rehab service.” Each of the 32 boroughs commissions its own adult service using its public health budget, which is why the provider, location and offer change at every borough boundary.
The practical upside: every borough service accepts self-referral. You don’t need a GP appointment first as you can phone, email or walk in and ask for an assessment.
Most services will triage you within days. Structured programmes, prescribing and any funding decisions take longer, typically weeks.
The free services nearest Clapham: Lambeth, Wandsworth and Southwark
Clapham sits where three boroughs meet, so which service you’re entitled to depends on your home address, not on where you’d prefer to be seen.
Lambeth
The Lambeth Drug and Alcohol Service supports anyone over 18 living in the borough. It’s delivered by a consortium led by South London and Maudsley NHS Foundation Trust (SLaM), and offers assessment, one-to-one keywork, group programmes and substitute prescribing.
Wandsworth
The Wandsworth Community Drug and Alcohol Service (WCDAS) is also a SLaM-led consortium, with its core service based at St John’s Therapy Centre in Battersea. It runs GP shared-care clinics across the borough alongside structured psychosocial support.
Southwark
Southwark’s adult service is run by the national charity Change Grow Live. It provides free assessment, structured recovery support and harm reduction for anyone living in the borough.
Live elsewhere in London? Search your borough’s name plus “drug and alcohol service”, every council publishes its commissioned provider, and self-referral is standard across all of them.
South London and Maudsley: when specialist NHS care gets involved
South London has something most of the country doesn’t. SLaM runs one of the UK’s leading addictions services, and it leads the community consortia in both Lambeth and Wandsworth.
For severe dependence, complex dual diagnosis or repeated unsuccessful community treatment, SLaM provides specialist secondary care, including inpatient detox in some cases. The pathway usually runs through your borough service or GP, who refers you on for specialist assessment.
Charity-funded residential rehab in and around London
A handful of charities offer residential places that don’t depend on council funding, usually through an enhanced housing benefit model, where your housing benefit contributes to the placement.
The Nehemiah Project, for example, runs abstinence-based residential recovery houses for men across South London, accepting referrals from anywhere for those eligible for housing benefit. Nationally, organisations such as Betel UK operate similar long-stay community models.
Be clear-eyed about who these services are for. Eligibility typically centres on homelessness or housing risk, benefits status and vulnerability as they exist for London’s most marginalised, not as a general alternative to paying for treatment.
How NHS-funded residential rehab actually gets approved
This is the question behind the question for most people searching for free rehab. The honest answer: it happens, but rarely, and the process is slow.
A funded placement is a local authority decision, not a GP prescription. The typical route looks like this:
- Engage with your borough’s community service: funding panels expect community treatment to have been tried first.
- Complete a comprehensive assessment with your keyworker, who builds the case for residential care.
- Go to funding panel: your borough decides whether to fund a placement, weighing clinical need against a limited budget.
- Wait for a bed: even approved placements can involve a waiting list.
End to end, this commonly takes months rather than weeks.
For someone whose drinking or drug use is medically dangerous, that timeline is the system’s biggest weakness and it’s the gap private treatment exists to fill.
Free recovery support groups in and around Clapham
London has the densest network of free mutual-aid meetings in the UK, and SW4, SW9 and SW11 are particularly well served.
You can turn up to most meetings without any referral, today, for nothing.
- Alcoholics Anonymous: hundreds of meetings across Greater London every week, including Clapham, Brixton and Balham (find a meeting)
- Narcotics Anonymous: meetings in every London borough (find a meeting)
- Cocaine Anonymous: for cocaine and all mind-altering substances (find a meeting)
- SMART Recovery: non-12-step, science-based groups, in person and online (find a meeting)
These work brilliantly alongside structured treatment rather than instead of it. Many of our own clients keep attending for years after leaving us.
Free vs private rehab in London: what actually differs
| Free (borough services) | Private residential | |
|---|---|---|
| Cost | £0 | From around £4,000 for 28 days at the affordable end |
| Format | Outpatient — you live at home | You live at the clinic, 24/7 medical cover |
| Access speed | Triage in days; programmes in weeks | Admission typically within 24 hours |
| Residential beds | Rare; funding panel decision over months | Immediate, subject to availability |
| Detox | Community or referral-based | Medically supervised on-site |
| Best for | Stable situations, early-stage problems, ongoing support | Physical dependence, failed community attempts, urgent need |
Neither column is “better” – they solve different problems. The free system is genuinely good at long-term community support; it is structurally bad at speed and at residential care.
When free isn't fast enough
For some situations, waiting weeks is not safe. Alcohol withdrawal can be medically dangerous for someone who is physically dependent, stopping suddenly without medical supervision risks seizures and delirium tremens.
Opioid dependence, or addiction alongside a mental health crisis, carries similar urgency. If that’s where you or your loved one is, tell your borough service explicitly that the situation is urgent and consider whether private treatment is the safer bridge.
At PCP London Clapham, our 9-bed centre near Clapham Common, we can typically arrange a medically supervised admission within 24 hours. We sit at the affordable end of what rehab costs in London, with payment plans available.
A confidential conversation with our admissions team costs nothing and commits you to nothing and if the free route is right for you, we’ll say so.
Frequently asked questions
Is rehab free in London?
Outpatient drug and alcohol treatment is free for every London resident through your borough’s commissioned service, and you can self-refer without seeing a GP. Free residential rehab exists but is rare as it’s funded case by case by your local authority, usually after community treatment has been tried.
Can you go to rehab for free in the UK?
Yes, through three routes: council-funded residential placements (limited and criteria-based), NHS specialist services, and charity beds funded through enhanced housing benefit. The great majority of free treatment, however, is community-based outpatient support rather than a residential stay.
How do you get rehab on the NHS?
Start with your borough’s drug and alcohol service or your GP. For a funded residential placement, you’ll typically need to engage with community treatment first, complete a comprehensive assessment, and have your case approved by a local authority funding panel, a process that usually takes months.
What can I do if I can’t afford private rehab?
Self-refer to your borough service today, it’s free and triage is usually quick. Free mutual-aid meetings (AA, NA, CA, SMART Recovery) run daily across London, and charity residential routes exist if you’re on benefits or at housing risk. Many private clinics, including ours, also offer payment plans.
How quickly can I get free treatment in London?
Most borough services offer triage within days of self-referral. Structured programmes and prescribing typically start within weeks; residential funding decisions take months. If your situation is medically urgent (especially alcohol dependence) say so explicitly when you contact the service.
