Mesyuarat perancangan untuk Operation Orb telah diadakan sekurang-kurangnya sekali setahun, dihadiri oleh wakil kerajaan, kakitangan Gereja England dan Clarence House.[4]

Raja Charles yang berusia 73 tahun diketahui membayangkan kerajaan beraja yang "langsing". Pertabalan baginda dijangka akan bersifat jimat-cermat, dan disebabkan usia baginda yang lebih pendek daripada bondanya.[6] Baginda dikatakan telah menyatakan hasrat agar pertabalannya, yang akan menjadi upacara Gereja England,[1] menjadi lebih mewakili kepercayaan dan komuniti etnik yang berbeza.[6] sumpah pertabalan diperlukan oleh statut; pengurapan, penyampaian orb, dan enthronement juga dijangka akan dilakukan.[6] St Edward's Crown is to be used for the ceremony.[1][6] Historic Environment Scotland announced in September 2022 that the Stone of Scone would be moved from the Crown Room of Edinburgh Castle to London for Charles's coronation at Westminster Abbey and returned to the castle after the ceremony.[9]

Charles's wife, Camilla, is also to be crowned, as queen consort. When Charles married her in 2005, it was declared that Camilla would not assume the title of queen upon his accession. Charles, however, had long wished for her to be so titled and crowned alongside him, and in February 2022, with Camilla's popularity rising, Elizabeth II declared her "sincere wish" that Camilla be known as queen upon Charles's accession.[10] Elizabeth is believed to have approved of Charles changing his coronation vows to include Camilla as queen some years ago during a wider review to bring the service up to date. Camilla is to be crowned with the Crown of Queen Elizabeth The Queen Mother. This would be the first coronation of a consort since that of Queen Elizabeth (later known as the Queen Mother) in 1937.[6]

As a state occasion, the coronation is paid for by the British government. The government thus also decides the guest list.[1] In contrast to Elizabeth II's coronation, which was attended by more than 8,000 people, the guest list for Charles III's coronation will be limited to 2,000 for health and safety reasons. The Commonwealth of Nations leaders and religious diversity are expected to be prioritised.[6]

After the ceremony, Charles and Camilla will appear on the Buckingham Palace balcony, probably with only the core royal family: his son William, Prince of Wales, daughter-in-law Catherine, Princess of Wales, and William and Catherine's children, Prince George, Princess Charlotte, and Prince Louis.[6]
