Why this school
One of a global network of Round Square schools, built on its IDEALS framework of internationalism and service.
Part of the Mill Hill Education Group, a federation of independent schools with roots in 1807 London.
Centred on a Grade I listed Elizabethan mansion, once home to the Earls of Darnley.
Cobham Hall School is a co-educational independent boarding school in Kent, set within 150 acres of historic grounds. Founded in 1962, the school has recently moved from a single-sex girls’ school to a fully co-educational community. It holds membership of the Round Square international network — a global association of schools committed to character development, international exchange, and service. With approximately 120 pupils, the school operates at an intimate scale. Small classes and close staff-pupil relationships are the norm rather than the exception. Cobham Hall is accredited by the Independent Schools Association (ISA) and the Boarding Schools’ Association (BSA).
Pupils work towards GCSEs in Years 10 and 11 and A-Levels in the sixth form. With only 120 pupils on roll, class sizes stay small and teachers can follow individual progress closely. A notable feature is Bligh House, a specialist SEND centre on site serving pupils aged 11–16. This means Cobham Hall can accommodate a wider range of learning profiles than most independent schools of comparable size. In 2025, 70% of A-Level grades were A*–C.
The sixth form spans Years 12 and 13, with A-Levels as the principal qualification. Termly fees for sixth form boarders stand at £17,565 (2025/26, VAT included), with day places at £9,995 per term. The deposit for international boarders is one term’s fees. In 2025, 43% of A-Level grades were A–B and 70% were A*–C.

Boarding is central to how Cobham Hall operates. The 150-acre Kent estate provides the physical backdrop for residential life, with weekend and evening activities drawing on both the grounds and the surrounding area. Pastoral care is structured around a house system. The small roll means houseparents and tutors work with the same pupils across several years, building continuity that larger schools rarely manage. Round Square membership adds an international dimension: exchange programmes and service projects connect Cobham Hall pupils with peers at member schools across six continents.
Round Square activities form a significant strand of the co-curricular programme. Pupils across the school can take part in international conferences, community service, and adventure expeditions. The 150-acre estate supports outdoor sports and activities directly on site. Drama, arts, and music sit within the broader programme. Because the school is small, pupils can take on substantial roles in productions and teams well before their senior years.
The school occupies a 150-acre estate in Kent, between Gravesend and the North Downs. Historic parkland sits alongside modern school facilities. With a compact pupil body, central spaces — classrooms, common rooms, sports areas — are shared across the whole school rather than divided by year group. That arrangement strengthens the cross-age relationships typical of smaller boarding communities. The scale of the site also gives the school room for the outdoor activities that are integral to its Round Square commitments.
