[2] Although Wales has English as a co-official language, their entries were sung primarily in Welsh due to being represented by a Welsh-language broadcaster.

Wales participated in the 2019 contest, represented by the song "Calon yn Curo" performed by Erin Mai and finished 18th with 35 points.

[5] On 25 August 2022, the British Broadcasting Corporation (BBC) announced that the United Kingdom would return to the contest in 2022 after a sixteen-year absence.

[6] On 16 November 2024, S4C confirmed that it did not participate in the 2024 contest due to the BBC's late withdrawal, leaving it with insufficient time to organise an entry and form a delegation.

However, a spokesperson for S4C stated that there is a prospect for Welsh participation in 2025, with 2018 representative Manw calling for a return to the contest.
