"A significant proportion from new and emerging UK artists" must feature on air.
Media watchdog Ofcom has ordered BBC Radio 1 to play more new music on daytime shows.
The ruling follows recent proposals from Ofcom which were introduced to ensure that Radio 1 and Radio 2 were playing new music at peak listening times, in order to ensure that they provide a distinctive change from other commercial stations.
Specifically, the popular must station’s daytime programming must include at least 50% new music, including “a significant proportion from new and emerging UK artists”.
The quota has been increased from an original proposal of 45%, while Radio 2’s new music threshold currently remains at 20%.
Ofcom has also considered the effects of streaming, which means that Radio 1 playlists could feature greater additions from “new music” defined by a period of 12 months from its first release or instead six weeks from the date it first enters the Top 20.
The new ruling reportedly comes into effect from April 1.
Last year, it was revealed that BBC Radio 1′s breakfast show has slumped to its lowest ratings since recent records began.
The show, which has been hosted by Nick Grimshaw for the last five years, attracted 5.3 million listeners over the age of 10 per week in the three months prior to the end of September 2017.
The show had attracted around 7 million listeners when Grimshaw took over the breakfast show in September 2012.
