In 1985, he won third prize at the National Young Organist of the Year Competition at Bolton. He also served on the Council of the Incorporated Association of Organists at this time.

Andrew has given recitals at the cathedrals of St Paul's, Westminster, Liverpool, Newcastle, and Southwark, and at Westminster Abbey. In France, at the Madeleine in Paris and the cathedrals of Notre Dame de Paris, Saint-Dénis, and Bourges. He has also played at churches and halls in England, Scotland, Northern Ireland and Germany.

In 1995, Andrew became Organist at St Matthew's, Westminster, where he is broadening access to the excellent 1989 Mander organ through his regular liturgical duties, the lunchtime recital series he has instigated (which is already attracting the finest organists), and his CD of organ music by J. S. Bach, recorded in 2002.

Andrew is performing this year on a number of fine organs in and around London, including at Westminster Cathedral; where he and James Longford played Andrew's new organ duet transcription of Mozart's Symphony 40. Recently, Andrew joined the editorial committee of the London Organ Concerts Guide.
