[6] On 1 August 2023, TaP Music, the label with which the BBC had collaborated to internally select the British act in 2022 and 2023, announced that it had terminated their partnership with the broadcaster.

[7] On 24 August, the head of entertainment at BBC, Kalpna Patel-Knight,[8] commented on the news, indicating that the broadcaster's intention was to look for another specialist team for 2024.

[14] On 16 February 2024, Alexander travelled to Tbilisi, where he met with Georgian representative Nutsa Buzaladze before filming the music video for "Dizzy" in the country.

[19] On 1 May 2024, the singer made a cameo appearance on an episode of the soap opera EastEnders, where he was seen rehearsing his Eurovision performance.

[23][24] The BBC commented that it was not in a position to cut ties with someone who is not a journalist over their personal use of social media, thereby confirming Alexander as the 2024 UK representative.

On 29 March 2024, Alexander released a joint statement with other Eurovision 2024 entrants – namely Bambie Thug (Ireland), Gåte (Norway), Iolanda (Portugal), Megara (San Marino), Mustii (Belgium), Nemo (Switzerland), Saba (Denmark), Silvester Belt (Lithuania) and Windows95man (Finland) – calling for "an immediate and lasting ceasefire" in Gaza as well as the return of the Israeli hostages held by Hamas.

[27][28] In an interview with The Times on 2 May 2024, the singer claimed to have experienced severe stress on the occasion, "trying not to have a breakdown" and feeling "ashamed of [himself] and embarrassed", while reiterating that he would participate as his withdrawal would not "make a difference" with regard to the humanitarian and hostage crises.

As a member of the "Big Five", the United Kingdom automatically qualifies to compete in the final on 11 May 2024, but is also required to broadcast and vote in one of the two semi-finals.

[37][38][39] In addition, as part of the Eurovision programming, the BBC cooperated with DR and SVT alongside other EBU member broadcasters – namely ARD/WDR, ČT, ERR, France Télévisions, NRK, NTR, RÚV, VRT, and Yle – to produce and air a documentary titled ABBA – Against the Odds, on the occasion of the 50th anniversary of Sweden's first victory at the contest with "Waterloo" by ABBA.

[46] The UK jury consisted of Maia Beth, Adam Murray, Louise Redknapp, Rika, and Kojo Samuel.

Over the course of the contest, the UK awarded its 12 points to Lithuania in the first semi-final, and to Portugal (jury) and Israel (televote) in the final.

Each participating broadcaster assembles a five-member jury panel consisting of music industry professionals who are citizens of the country they represent.

[52] The individual rankings of each jury member as well as the nation's televoting results were released shortly after the grand final.
