Miller-Bakewell registered the duke's death with the Royal Borough of Windsor and Maidenhead on 13 April 2021. Miller-Bakewell took part in the duke's 17 April funeral. He walked in the funeral procession behind the duke's hearse and senior members of the royal family. He walked alongside other royal staff (two pages and two valets) and a police royal protection officer. Despite pre-event speculation, he was not one of the thirty attendees permitted to attend the funeral service at St George's Chapel, Windsor Castle, under the government restrictions on funeral attendance numbers due to the COVID-19 pandemic. The attendees were all members of the British or foreign royal families.
