A registered charity, the Royal Collection Trust was set up in 1993 after the Windsor Castle fire with a mandate to conserve the works and enhance the public's appreciation and understanding of art. It employs around 500 staff and is one of the five departments of the Royal Household. Buildings do not come under its remit. In 2012, the team of curatorial staff numbered 29, and there were 32 conservationists. Income is raised by charging entrance fees to see the collection at various locations and selling books and merchandise to the public. The Trust is financially independent and receives no Government funding or public subsidy. A studio at Marlborough House is responsible for the conservation of furniture and decorative objects.
