Private Schools in Hillingdon

The London Borough of Hillingdon holds a distinctive place on Greater London’s north-western border, combining suburban green belt enclaves with a rich heritage of grand country estates and pioneering girls' education. The borough’s independent schooling traditions flourished rapidly around the turn of the 20th century, anchored by the growth of Northwood, where St Helen’s School was established in 1899 to promote high academic standards for young women.

Hillingdon is also uniquely defined by its historic estate conversions, most notably Hillingdon Court—an 1854 mansion built for the prominent Mills banking family—which now serves as the campus for ACS Hillingdon International School. Independent provision across Hillingdon displays impressive diversity, ranging from prestigious, high-achieving single-sex day settings such as St Helen’s School and Northwood College for Girls GDST to global International Baccalaureate foundations like ACS Hillingdon International School and boutique preparatory environments such as St Martin’s School and St John’s School.
