Egerton House is named after the School's founder, Rev. Philip Reginald Egerton. It is a boys house which stands in a corner of the main campus close to the science buildings. Robin Thompson is the Housemaster and teaches Business Studies.
Egerton is situated on the edge of the School campus, part of it overlooking Rosebank. The House is entered by a large conservatory where the boys can sit during break and social times. There are about 60 boys in the house, split between five year-groups. The boys use a dayroom in their first year and boarders use a dormitory. Then, in the fourth form, they share a double or treble room, as well as using a day room for prep and free time. Fifth formers may be lucky enough to have their own space, though a double study is more likely whilst sixth formers do have private quarters. The Housemaster’s house is attached to the conservatory and the Assistant Housemaster, has his accommodation on the ground and first floors at the eastern end of the House.
