Mill Hill Education Group

What Mill Hill Education Group does

Mill Hill Education Group is a UK-registered charitable organisation (Charity No. 1064758) that operates a network of 16 independent day and boarding schools across England and, as of September 2025, internationally in Chiang Mai, Thailand. The portfolio spans pre-prep (ages 2-7), prep (ages 3-13), and senior schools (ages 11-18), with boarding available at Mill Hill School, Mill Hill International, and Cobham Hall. Specialist offerings include 1729 Maths School (the UK's first dedicated maths secondary school, ages 11-18, launched in 2025 with Purposeful Ventures) and Bligh House, a SEND autism centre at Cobham Hall developed with Chiltern Way Academy Trust. Revenue is primarily subscription/recurring tuition and boarding fees, supplemented by transaction-based commercial venue and facility hire managed through a dedicated schoolhire.co.uk platform. Growth has been driven by charitable mergers rather than traditional M&A: the network expanded from a single school in 2013 to 16 schools by mid-2026, including four mergers in 2026 alone.

The Group's go-to-market is a hybrid sales-led model with school-by-school direct admissions, open days, and tours as primary conversion channels, supported by digital presence (corporate site, Instagram @MillHillEduGrp) and earned media. Distribution is concentrated in affluent UK catchment areas (London Mill Hill, North London, Kent, Hertfordshire, Berkshire, Suffolk) plus the new Thai location. Distribution channels also include international student recruitment via Mill Hill International (ages 13-17) and an exclusive NCUK partnership for the International Art and Design Foundation Programme launching September 2026 at Cobham Hall. Marketing emphasises the Group's shared values, academic record (notable ISI 'significant strength' ratings and 2026 Independent Schools of the Year commendations), and breadth of co-curricular offerings across the network.

Operationally, the central corporate team is small (26 reported employees), with each school operating its own admissions, teaching staff, and identity while benefiting from group-level shared services in safeguarding (Jane Morris, Group Director of Safeguarding), fundraising and development (Lucia Hull, Director of Development), and governance under Chair Elliot Lipton and Vice Chair Stephanie Miller. CEO Antony Spencer leads the network. Differentiated structural advantages include the 1807 heritage, 250+ acres of owned grounds, charitable status enabling merger-led inorganic growth, and a partner ecosystem spanning professional sport (Saracens, Tottenham Hotspur, Middlesex Cricket, Hampstead & Westminster Hockey) and university pathway providers (NCUK).
