Eligibility Who Can Use Weight Loss Treatments?Our weight loss treatments are prescription-only medicines available to adults who meet specific clinical criteria. All patients undergo a free online consultation reviewed by a UK-registered prescriber before any treatment is supplied.
BMI 30+ Standard eligibility A BMI of 30 or above meets the standard clinical threshold for prescription weight loss treatment. No additional health conditions are required to qualify at this level.
BMI 27+ With a health condition A BMI of 27 or above can qualify if you have at least one weight-related health condition such as high blood pressure, type 2 diabetes, high cholesterol, or sleep apnoea.
BMI 27.5+ Ethnicity-adjusted threshold A lower BMI threshold of 27.5 (or 25 with a co-morbidity) may apply if you are of South Asian, Chinese, Black African, African-Caribbean, or Middle Eastern family background, in line with NICE guidance.
Clinical assessment required All treatments require a full clinical assessment reviewed by a UK-registered prescriber. Eligibility is confirmed individually — a BMI alone does not guarantee supply. Start your free assessment to find out if you qualify.
