[2] He was a chorister at Westminster Cathedral, and he frequently sang in works composed or conducted by his godfather, Benjamin Britten.

The original drafts for Jane Eyre, representing one year's worth of work and the only copy of them, were stolen from outside his London home in May 1999.

He arranged the choral sequences for Hello Earth, a song written by Kate Bush which appeared on her studio album Hounds of Love in 1985.

He wrote This Endernight for the 2016 King’s College Festival of nine Lessons and Carols and Super Flumina Babylonis for the St. Cecilia Day Service in Westminster Cathedral in 2017.

In June 2024 Orchid Classics released Collaborations, a CD of Berkeley's music featuring artists he had worked closely with and written for.

[15] These included Mahan Esfahani, Clare Hammond, Madeleine Mitchell, Alice Coote, Julius Drake and the BBC Singers.

The album includes a song for Ukraine, Zero Hour, with lyrics and vocals from Neil Tennant and guitar solos from David Gilmour.

Since 1995 Berkeley has presented BBC Radio 3's Private Passions,[2] in which celebrities are invited to choose and discuss several pieces of music.

In December 1997, one of his guests was a 112-year-old Viennese percussionist called Manfred Sturmer, who told anecdotes about Brahms, Clara Schumann, Richard Strauss, Arnold Schoenberg and others so realistically that some listeners did not realise that the whole thing was a hoax perpetrated by Berkeley and John Sessions.

[22] Berkeley was appointed a Commander of the Order of the British Empire (CBE) in the 2012 Birthday Honours for services to music.

Subsequently, first the Home Secretary and then the Prime Minister told parliament that they would find Government time for the Bill, which finally received Royal Assent on 15 March 2019.
