A graduate of University College London and classically trained pianist, Simon’s career as a television composer took off in the mid-90s when he scored numerous projects for the then fledgling RDF Television, also doing documentary work for the BBC and others. 

His reputation as a sensitive and original composer for drama has been growing rapidly since his work on Carlton's remake of E. Nesbit's The Railway Children in 2000. For this film, he created a beautifully lyrical chamber orchestra score evoking the idealised world of Edwardian childhood. Simon’s title theme for the BBC's 6-part legal drama Fish has been a particular hit wherever the series has been broadcast; and for LWT's modern-day adaptation of A Christmas Carol, starring Ross Kemp as Scrooge, he created an atmospheric and haunting orchestral score. 

Recent television work includes the ITV comedy-drama Monday Monday, ITV comedy Pickles - the Dog Who Won the World Cup, and several Simon Nye-scripted comedies for Talkback Thames including Open WideTunnel of Love and Beauty, the latter starring Martin Clunes.  

In the documentary field, Simon composed the music for Pioneer Productions' highly acclaimed documentary film Life Before Birth (broadcast on Discovery as In the Womb). He also wrote the title theme for BBC2's 7-part series British Film Forever, leading the BBC's Summer of British Film in 2007. Simon has also enjoyed working on a couple of historical drama-documentaries: Mary Shelley: The Birth of  Frankenstein, for the BBC (for which he was able to dip his toes into the horror  genre); and Anthony and Cleopatra for Wall to Wall.  

In contrast to these dramas, Simon has also worked on long running entertainment and news shows, including RDF's Scrapheap Challenge and The BBC’s Politics Show - a reflection of his eclectic ability to work in any style, to any brief.  

In 2003, Simon scored his first feature film Lena, directed by up-and-coming director Polly Steele. More recently, he has composed the music for the feature film Good, starring Viggo Mortensen and directed by Vicente Amorim. This was  released internationally in 2009, and his score received a very positive response on the festival circuit around the world.

He has just completed the music for the Wall to Wall series "Long Lost Family" for ITV1, presented by Davina McCall and Nicky Campbell and is currently finishing writing music for the forthcoming album "A Quarter of a Million Miles", which was inspired by Apollo 11 astronaut Michael Collins' book "Carrying the Fire".
