Mill Hill International School Thailand

Mill Hill’s Chiang Mai campus opened in September 2025 in partnership with Ornsirin. It carries the name of the London school founded in 1807, but local provision and outcomes need their own assessment. Its 2026/27 fee page publishes Nursery through Year 9 bands. The admissions page describes a wider senior-school journey, but a planned pathway or fee band is not confirmation of an operating class. Check the current year groups and qualification cohorts directly.

Annual tuition (2026/27): ฿447,300–฿642,600 (~$13,763–$19,772)

Public feedback: We did not find enough independent, dated enrolled-family feedback to judge the Chiang Mai campus. Its London namesake’s history is not evidence of this newer campus’s outcomes. For a child approaching the end of primary, check the classes operating now and the fallback if a planned secondary phase opens later than expected.
