Simcott was born in the UK, with English as his first language, quickly learning French at a young age (he says he does not remember not speaking French). He grew up in the English Wales Border districts so quickly learnt Welsh as well. His father re-married a Thai woman, so he started to learn Thai on some trips there as a teenager. Since that time he has learned a range of languages including Turkish, Polish, Hebrew, Chinese, Icelandic, Macedonian and Esperanto. Simcott has worked with languages in the UK diplomatic service, he has been a production manager for Emoderation as well as being the languages director for Polpea. He has also hosted a range of Polyglot conferences internationally, and is the current head of the Polyglot conference. He was interviewed by 16×9 for a short television programme about polyglots. Simcott runs his own Blog "Speaking Fluently" and has published a book on French Short Stories. In 2015 the Goethe Institut named him Ambassador for Multilingualism.
