text: On 9 April 2021, following the death of Prince Philip, Duke of Edinburgh, the episode of EastEnders that was due to be aired that night was postponed along with the final of Masterchef. In May 2021, it was announced that from 14 June 2021, boxsets of episodes would be uploaded to BBC iPlayer each Monday for three weeks. Executive producer Sen explained that the bi-annual scheduling conflicts that the UEFA European Championship and the FIFA World Cup cause to the soap, premiering four episodes on the streaming service would be beneficial for fans of the show who want to watch at their own chosen pace. Sen also confirmed that the episodes will still air on BBC One throughout the week. The release of these boxsets was extended for a further five weeks, due to similar impacts caused by the 2020 Summer Olympics.
  On 12 October 2021, it was announced that EastEnders would partake in a special week-long crossover event involving multiple British soaps to promote the topic of climate change ahead of the 2021 United Nations Climate Change Conference. During the week, beginning from 1 November, a social media clip featuring Maria Connor (Samia Longchambon) from Coronation Street was featured on the programme while Cindy Cunningham (Stephanie Waring) from Hollyoaks was also referenced. Similar clips featuring the show's own characters, Bailey Baker (Kara-Leah Fernandes) and Peter Beale (Dayle Hudson), were featured on Doctors and Emmerdale during the week.
