He first appeared in Series 1, losing his debut game to Joe Guy. A computer manager from Isleworth, Middlesex, he was later invited back for Series 6, where he became an octochamp. In his semifinal against Adam Gilinsky he scored 72 points, the highest of the series. He then went on to beat Olivia Lloyd in the grand final, and became the first ever Xicount, or series champion who was also an octochamp.
Unable to play in Championship of Champions II due to a broken leg, he was invited back in 1987 for Championship of Champions III, where he defeated Steve Balment in the quarter-finals before narrowly succumbing to David Trace 58 – 55 in the semis. He also appeared on the special episode to celebrate Countdown's 500th show on 2 February 1987, and competed in the Countdown Masters in 1989.
Francis returned to Countdown in 1996 for the Supreme Championships where, after a first round win over Mike Percik, he was defeated by Allan Saldanha, who equalled the record for the highest score ever achieved in a 9 round game of Countdown.
He returned to the show again in 2013, as one of 41 contestants taking part in the 30th Birthday Championship; of these, he was the one who originally appeared on Countdown the earliest. He won his first match against Series 22 semi-finalist David Webb by a score of 86 – 68, then beat Series 21 champion Barry Grossman in the first round, before losing to Series 53 semi-finalist Jon O'Neill, despite scoring a personal best of 91.
