Stewart is 27 and works for a printing company. He is married to Julie, who is originally from Canada, and together they live in Nottingham with toddler Jasper (born December 2005).

Stewart's greatest Scrabble achievement has been to make it into the England team for the 2003 World Championships, which took place in Kuala Lumpur, Malaysia. His UK tournament successes so far have included winning the top group of the Nottingham Nomads tournament twice and the ABSP Summer Matchplay and Isle of Wight events. He also won the 2004 series of the Channel 4 quiz show Countdown and still gets old ladies stopping him in the street to talk about it.
