In 1999, he was appointed director of the BBC National Chorus of Wales – a position which he still holds, and has involved preparing the chorus for many concerts, BBC Radio 3 broadcasts, BBC Proms appearances and recordings under conductors such as Richard Hickox during his years as principal conductor of BBC National Orchestra of Wales.

He was appointed director of music at Gloucester Cathedral in 2007, and took up the post in January 2008, along with the positions of conductor of Gloucester Choral Society and joint conductor of the Three Choirs Festival. The 2010 Gloucester festival was the first under his artistic direction where he programmed the festival and conducted several concerts with the Philharmonia Orchestra including the world premiere of John Joubert's An English Requiem.
