The Lord Chamberlain’s Office is responsible for organising those elements of The Queen's programme that involve ceremonial activity.

Despite its name, the Lord Chamberlain’s Office is as independent of the Lord Chamberlain as the other Departments. It is headed by the Comptroller.

The Central Office is responsible for managing the two inward State Visits by overseas Heads of State each year, Investitures, Garden Parties, the State Opening of Parliament, the Garter and Thistle Services, Swan Upping, Royal Warrants, Trade Marks, Royal Insignia, Ceremonial Body Guards, the Crown Jewels, and part-time and honorary appointments, including the Ecclestiastical and Medical Households. It organises Royal weddings and funerals and other special events.

The Royal Mews, managed by the Crown Equerry, is the branch that provides all coaches, carriages and cars for State and official occasions.

The Central Chancery and the Orders of the Knighthood co-ordinates all matters relating to honours that are awarded by The Queen at Investitures on the recommendation of the Prime Minister.

The Marshal of the Diplomatic Corps is the link between the Sovereign and the Heads of Diplomatic Missions in the United Kingdom (currently more than 150).

The Lord Chamberlain’s Office is also responsible for some of the most ancient traditions connected with the Monarchy.
