|5 Live Sports Extra||Live sport - used to broadcast either Test Match Special or a second sporting event when BBC Radio 5 live is also broadcasting live sport.|
|Yesterday In Parliament||Radio 4 LW opt-out simulcast; Weekdays 08:30-09:00; Saturdays 08:45-09:00.|

In recent years, the BBC has begun experimenting with short-term "Pop-up" digital radio stations, each broadcasting for approximately 4 days at a time, covering music festivals and other special events. The first to broadcast was BBC Radio 5 Live Olympics Extra in 2012, then BBC Radio 2 Eurovision launched for the first time in 2014, and was joined by BBC Radio 2 Country, BBC Music Jazz in 2015 and BBC Radio 2 50s in April 2016. When these temporary stations are on air, there is normally a reduction in bit rate of their parent station (Radio 1, Radio 2 or Radio 3).
|BBC 5 Live Olympics Extra||Available during 2012 Summer Olympics with coverage consisting of sports commentaries.|
|BBC Radio 2 Eurovision||Launched in May 2014 to extend the BBC's coverage of the Eurovision Song Contest. Returned in 2015 to provide coverage of the 2015 contest.|
|BBC Radio 2 Country||Launched in March 2015 to provide coverage of London's C2C: Country to Country Country music festival. Returned in 2016 to cover the 2016 festival and again in 2017.|
|BBC Music Jazz||Launched in November 2015 as a joint venture between BBC Radio 3 and Jazz FM, with programming celebrating Jazz music in all its varied forms.|
|BBC Radio 2 50s||Launched in April 2016 as a celebration of the music and entertainment of the 1950s.|
|BBC Radio 1 Vintage||Available in September 2017 as a celebration of BBC Radio 1's 50th anniversary.|
|BBC Radio 2 Beatles||Launched in September 2019 as a celebration of 50 years of the Beatles album Abbey Road featuring interviews on how the album was created and how it influenced the next generation of music artists.|
BBC Asian Network was due to be axed in around 2011 after plans to close down the station were published. The BBC also planned to close 6 Music. Since then both stations have been saved from closure – 6 Music was retained after listening figures increased and a campaign was set up on Facebook which had 180,000 supporters.
