Rehab and Detox in London and Kent
Promis provides alcohol rehab and drug rehab from two small residential clinics: Hay Farm in the Kent countryside and Kendrick Mews in central London. Medically supervised detox is available where it is needed, with weekly psychiatric input throughout treatment. Because Promis is a mental health and addiction clinic, anxiety, depression, trauma, and eating difficulties are treated alongside the addiction rather than left for later.
