Simon works in the telecoms and technology industry. 

In April 2009, following a whiplash incident, he woke in the middle of the night with loud ringing in his right ear. His struggle with tinnitus and its associated complications commenced at that point and subsided only after a period of several years of tinnitus retraining therapy.

He was appointed a trustee of the British Tinnitus Association in September 2018.

He enjoys modern fiction and running, albeit more slowly these days.
