The royals will join dignitaries from around the world in the more than 1,000-year-old abbey as they pay their respects to the beloved Queen Elizabeth II.
After proceedings conclude, the procession will set off for Wellington Arch at Hyde Park Corner.
The state hearse will later depart on its journey to Windsor as the parade gives a royal salute and the National Anthem is played.
The King, joined by Queen Consort Camilla and other members of the Royal Family, will then depart for Windsor by car.
A committal service will take place in Windsor Castle's historic St George's Chapel this afternoon, after which members of the Royal Family will depart the Galilee Porch and bring a close to the public ceremonial arrangements.
A private burial service will be conducted by the Dean of Windsor at 7.30pm, attended by the King and members of the Royal Family.
Queen Elizabeth II will then be buried together with her beloved Prince Philip, Duke of Edinburgh, at the King George VI Memorial Chapel.
It is the second time William and Harry have put aside their differences as the magnitude of the occasion has not escaped them.
On Wednesday, in a scene reminiscent of when they followed their mother Princess Diana's casket as boys 25 years ago, they followed Her Majesty's coffin as it was moved from Buckingham Palace to Westminster Hall.
