London, United Kingdom Jul 26, 2026 (Issuewire.com) - Siam Rehab, a licensed residential facility in Chiang Rai, caps admissions at 18 clients and structures treatment outside the standard 12-step model, an approach increasingly sought by UK residents exploring options abroad.
Demand for addiction treatment in the UK continues to climb. According to figures published by England's Office for Health Improvement and Disparities (OHID), the number of adults in contact with drug and alcohol treatment services in England rose 7% in 2023-24 compared with the previous year, the largest year-on-year increase since 2008-09, with close to 159,000 adults entering treatment during that period.
Against this backdrop, a growing number of UK residents are researching treatment options outside the country, including facilities structured differently from the group-based, step-driven models most commonly available domestically. Siam Rehab, a licensed private residential treatment facility in Chiang Rai, Thailand, is one such option now seeing increased enquiries from UK-based clients.
Siam Rehab operates as a non-12-step residential programme built around cognitive behavioural therapy, motivational interviewing, dialectical behaviour therapy, and individualised treatment planning rather than a fixed group-step curriculum. The facility deliberately limits capacity to a maximum of 18 clients at any time, a structural choice that shapes its staff-to-client ratio of approximately 1:1.3 and counsellor-to-client ratio of approximately 1:4-5.
"A lot of people looking into treatment assume the choice is between a UK waiting list and a large, group-based programme," said Roy Faessen, Director (Europe) at Siam Rehab. "We've built something different: a small, fixed-capacity setting where treatment planning starts from the individual rather than a shared curriculum."
Clinical care at Siam Rehab includes psychiatric oversight through an on-site clinic seven days a week, individualised therapy planning across the resident's stay, and a structured continuing-care process. Before discharge, each client works with their primary counsellor to prepare a written aftercare plan, which may include relapse-prevention strategies, medication and psychiatric follow-up recommendations, telehealth scheduling, and referrals to local support resources in the client's home country. Siam Rehab has operated in Chiang Rai for more than a decade.
For UK residents, the process begins with an initial assessment call to determine clinical suitability for residential treatment. Because capacity constraints are rarely the limiting factor on the facility's side, admission can typically follow soon after assessment, without a waiting list.
Siam Rehab's clinical team includes on-site counsellors, a licensed clinical psychologist, and an external psychiatrist providing weekly on-site clinic hours and telehealth availability, supported by an external network of medical advisors for specialist and complex cases, including advisors based in Europe who assist with intake coordination for UK and European clients.
