There are currently eight houses at Tiffin. Theses houses and their associated colours are:
Since 1919 every student and teacher at Tiffin School has been assigned to a house upon arrival at the school. Each house is led by a teacher - the head of house, and a student or students from within the house - the house captains. They are responsible for overall control and organisation of house activities throughout the year.
Houses compete annually for the House Trophy which is awarded to the winning house at the end of the competition, which consists of academic and sporting events. The house with the highest points score is presented the trophy on Sports Day, usually the Wednesday of the last week of the Summer Term. The name of the winning house and year is recorded on the gallery in the school hall.
