The school has been called "the brainchild of
Tony Fernandes", a
Malaysian business magnate who had been educated at the original
Epsom College in England. Tony Fernandes gained the support of the head of the English Epsom College,
Stephen Borthwick, who also played a leading role in the creation of the school. Borthwick announced the project in December 2009, stating that the new school would follow a British curriculum and teach about 900 children between the ages of eleven and eighteen, mostly
boarders. He said a high calibre project team had been put in place. In 2010, Borthwick added that it was planned to employ teaching staff mostly from the United Kingdom. The Malaysian government gave the project its support, and the new buildings and campus were built according to designs by a British firm, NVB Architects. In June 2012, the new Epsom College was nearing completion on a campus at Bandar Enstek. Borthwick said there would be "real pollination between the two schools through pupil and staff exchanges". The school finally opened in September 2014. In December 2014,
Boris Johnson visited the school for its opening ceremony, joining
Tunku Ali Redhauddin, eldest son of the
Yamtuan Besar of
Negeri Sembilan, the British High Commissioner to Malaysia,
Victoria Treadell, and Tony Fernandes, who was the first Chairman of the Governing Body. By 2018, Fernandes and his partners had invested
RM150 million in the school. ==Campus==
