Rehab vs AA / NA
Clinical treatment and mutual-aid recovery are different tools. Most sustained UK recoveries use both, in sequence.
Rehab (clinical treatment)
CQC-regulated NHS or private treatment with clinical assessment, detox and structured therapy.
- Safe medical detox
- Clinical assessment for dual diagnosis
- Structured evidence-based therapy (CBT, MI, trauma work)
- Time-limited and intensive
- Costs money or requires funding-panel approval
- Ends — often abruptly at 28 days
- Doesn't provide long-term community
Best for: Getting stopped safely, resolving the underlying drivers, stabilising for the first 3–6 months.
AA / NA (mutual aid)
Free, member-run 12-step fellowships. Regular meetings, sponsor relationships, community of people in recovery.
- Free, forever
- Available in every UK town and online, daily
- Long-term community and identity
- Accountability from people who've been there
- Doesn't provide medical detox
- 12-step framing doesn't suit everyone
- Quality varies by meeting
- No clinical screening for dual diagnosis
Best for: Long-term maintenance of recovery — the 3-year and 10-year problem, not the first-week problem.
Side-by-side
| Rehab (clinical treatment) | AA / NA (mutual aid) | |
|---|---|---|
| Cost | £4,500–£30,000+ (private) or free (NHS) | Free |
| Medical detox | Yes, supervised | Not provided |
| Clinical assessment | Yes | None |
| Long-term community | Alumni groups vary | Core feature |
| Availability | Days-weeks lead time | Same day, worldwide |
| Evidence base | Strong — CBT, MI, trauma-informed | Strong (Cochrane 2020) — for those who engage |
| Secular alternative | n/a | SMART Recovery UK — CBT-based, secular |
Our take
These are not competing products. Rehab is treatment; AA / NA is recovery community. Rehab is finite and intensive; AA is infinite and low-intensity. Most people in sustained UK recovery used rehab to get stopped and AA (or SMART, or a similar community) to stay stopped.
If money is a hard constraint and your withdrawal risk is low: skip rehab, use the NHS community service for detox, and go straight into AA / SMART. If withdrawal risk is high, do a supervised detox first — then plug into a fellowship.
The one route we consistently see fail: private rehab followed by nothing. A £15,000 stay with no aftercare has worse outcomes than free AA attended twice a week for two years.
Common questions
Is AA as effective as rehab?▾
The 2020 Cochrane review found AA and 12-step facilitation produced abstinence outcomes comparable to CBT and other manualised therapies over 12–36 months — for people who engage. AA doesn't do medical detox and doesn't provide clinical assessment, so it's not a substitute for treatment where withdrawal is dangerous.
Do I have to believe in God to do AA?▾
AA uses the phrase 'higher power as we understood him', which many members interpret non-religiously — as the group, nature, or the idea of something bigger than the individual. SMART Recovery is a fully secular UK alternative if the language doesn't fit.
How much does AA cost?▾
AA is free. There's an optional collection at meetings — usually £1–£2. There are no membership fees. UK rehab, by contrast, costs £4,500–£30,000+ per admission.
