The two chapels are also used for certain Royal ceremonies.

Each year the feast of Epiphany is celebrated on 6 January in the Chapel Royal with a service of Holy Communion, when an offering of gold, frankincense and myrrh is made on behalf of The Queen.

Both chapels have been used in recent years for the lying-in-state of members of the Royal Family. The coffins of Queen Elizabeth The Queen Mother and Princess Margaret lay at The Queen's Chapel, while that of Diana, Princess of Wales lay in the Chapel Royal at St. James's Palace.
