Following the renaming of the historic
Hull Grammar School as the William Gee School for Boys in 1988, the name was acquired and used for a new independent school which opened in 1989. In 1991, Nord Anglia Education PLC, an education and training company, acquired the new school from the administrator for £900,000. By 2003 the school (net asset value of £1,800,000) hosted 450 pupils - boys and girls - from two to 18 years of age, and registered a turnover of £2,400,000, of which £280,000 went to Nord Anglia. The School was purchased from Nord Anglia for £4,180,000 by the United Church Schools Company (affiliated to the Church of England), and merged in September 2005 with Hull High School for Girls (owned by the Company since 1890), a co-educational Independent School (with a girls-only junior and senior school, ages 7–18) of similar size and strength. This merged Hull Collegiate School is situated on the former Hull High School site to the west of
Hull and north east of the
Humber Bridge, the school is based at
Tranby Croft, a Victorian mansion with over of landscaped grounds, a small wood and an
AstroTurf pitch. The mansion was previously home to shipbuilder
Arthur Wilson during the late
Victorian Era. He hosted the Prince of Wales, later King
Edward VIII, at a party. The events at the party would later lead to the
royal baccarat scandal. The Preparatory School, opened in 2004, is housed in a purpose-built facility on the same site; a senior school building was opened in 2005, completing a multimillion-pound investment by parent company
United Church Schools Trust. The school was renamed Tranby in 2021, after the site, Tranby Croft. ==Notable alumni and teachers==
