Siam Rehab Receives Joint Government Accreditation From HAI and NISAD, Thailand’s Healthcare Certifiers

London, United Kingdom Jun 19, 2026 (Issuewire.com) Siam Rehab, a licensed private residential addiction treatment centre in Chiang Rai, Thailand, has received formal accreditation jointly issued by the Healthcare Accreditation Institute (HAI) and the National Institute for Drug Abuse Treatment and Rehabilitation (NISAD), Department of Medical Services, Ministry of Public Health. The accreditation is valid from 20 May 2026 through 19 May 2029.

What Is HAI, and Why Does It Matter?

The Healthcare Accreditation Institute (HAI) is an independent public organisation established by Royal Decree in 2009. It operates under its own governance – not as a government department – and is responsible for evaluating and certifying healthcare facilities across Thailand against national quality benchmarks. HAI accredits the country’s leading public and private hospitals. When HAI certifies a facility, it means an external review body – not the facility itself – has audited its clinical systems, staffing standards, and patient safety protocols and confirmed they are compliant.

NISAD, operating under the Department of Medical Services, provides specialist oversight specifically for drug treatment and rehabilitation facilities. A joint HAI-NISAD certificate is the highest form of accreditation available to a private addiction treatment centre in Thailand.

Is Siam Rehab Accredited?

Yes. Siam Rehab holds a joint accreditation certificate from HAI and NISAD, valid 20 May 2026 – 19 May 2029. The certificate was issued following an independent audit of the centre’s clinical governance, staff qualifications, treatment programmes, and patient safety systems.

Why This Matters for UK Residents Seeking Treatment Abroad

For individuals and families in the United Kingdom considering residential treatment abroad, independent accreditation addresses the central question of clinical credibility. The majority of private rehabilitation centres operating in Southeast Asia carry no external accreditation and have not been subject to formal independent review. For UK residents accustomed to regulated healthcare environments, this distinction is significant.
Siam Rehab’s HAI-NISAD accreditation provides the same assurance principle that underpins regulated healthcare in the UK: an independent body – not the provider – has reviewed the evidence and confirmed the standards are met.

The centre operates a non-12-step, abstinence-focused programme built on Cognitive Behavioural Therapy (CBT), Dialectical Behaviour Therapy (DBT), Motivational Interviewing (MI), and Rational Emotive Behaviour Therapy (REBT). It maintains a maximum capacity of 18 clients, with a counsellor-to-client ratio of approximately 1:4-5 and daily on-site psychiatric oversight provided by a licensed psychiatrist (Medical Council of Thailand No. 155270).
“This accreditation answers a question families ask us constantly: how do we know your standards are real?” said Wade Dupuis, Managing Director of Siam Rehab. “The answer is now straightforward – because two independent government-affiliated bodies reviewed our clinical operations and confirmed they meet national benchmarks. That verification does not come from us. It comes from them.”

Clinical Outcomes (Internal Data, 2022-2025, n=250)

Internal follow-up data from 250 clients treated between 2022 and 2025 shows a programme completion rate of 97%, with 80% of clients voluntarily extending their stay beyond the original programme length. The average length of stay was 7.75 weeks. The centre’s Net Promoter Score for the same period was +78. These figures are based on internal follow-up reporting and are not predictive of individual outcomes.

Siam Rehab serves English-speaking clients from the United Kingdom, Australia, the United States, and Canada. The centre is located on a 30-acre campus in Mae Chan, Chiang Rai, and offers residential programmes from 4 weeks to 12 months, starting from EUR 8,500 for a four-week stay. Domestic bank transfer is available from UK accounts.
