[1] Stand Uniqu3, a girl group specially formed by the BBC following auditions, were selected to represent the United Kingdom with the song "Back to Life", written and composed by Sky Adams, Jakke Erixson and Jack Hawitt.

[6] ITV, the national broadcaster responsible for the first three participations, withdrew from the Junior Eurovision Song Contest in 2006, after poor viewing figures in 2004 and 2005.

On 25 August 2022, it was confirmed that the UK would return for the 2022 contest in Yerevan, with the BBC replacing ITV as the country’s participating broadcaster.

The song was written by Sky Adams, Jakke Erixson and Jack Hawitt, the latter of whom was also a songwriter for "Lose My Head", the British entry in 2022.

We have a great song and high hopes for our brilliant trio, Stand Uniqu3, and we want families everywhere to cheer on Hayla, Maisie and Yazmin and watch them represent the UK in the competition across BBC Two, CBBC and iPlayer.

[17] On 4 November, they gave their first lip sync performance of "Back to Life" on the CBBC children's television programme Blue Peter.

[19][20] On 17 November, Stand Uniqu3 gave a live TV performance of their entry on the BBC's annual charity appeal show Children in Need.

[23][24] The BBC also confirmed that children's TV presenter Lauren Layfield and singer Hrvy would return as commentators for the second year running.

[23] Stand Uniqu3 and the UK delegation also participated in the Opening Ceremony for the contest, which was held in Hotel Negresco in Nice on 20 November 2023, during which the running order was also determined.

[27] Juliet Russell served as vocal coach for the group, both for the performance in Nice and the original recording of "Back To Life".

Each nation's jury consisted of five members: three adult music industry professionals and two children, who are citizens of the country they represent.

This jury judged each entry based on: vocal capacity; the stage performance; the song's composition and originality; and the overall impression by the act.
