The Comptroller of the Household is an ancient position in the British royal household, nominally the second-ranking member of the Lord Steward's department after the Treasurer of the Household. The Comptroller was an ex officio member of the Board of Green Cloth, until that body was abolished in the reform of local government licensing in 2004. In recent times, a senior government whip has invariably occupied the office. On state occasions the Comptroller carries a white staff of office, as often seen in portraits.

The King's Wardrobe, together with the Chamber, made up the personal part of medieval English government known as the King's household. Originally the room where the king's clothes, armour, and treasure were stored, the term was expanded to describe both its contents and the department of clerks who ran it. Early in the reign of Henry III the Wardrobe emerged out of the fragmentation of the Curia Regis to become the chief administrative and accounting department of the Household. The Wardrobe received regular block grants from the Exchequer for much of its history; in addition, however, the wardrobe treasure of gold and jewels enabled the king to make secret and rapid payments to fund his diplomatic and military operations, and for a time, in the 13th-14th centuries, it eclipsed the Exchequer as the chief spending department of central government.
