Infinity FC were formed in 2006 by Jody Hoare, Simon Tribe and Scott Finlayson, initially joining the Winchester & District League. The club enjoyed rapid progress, winning the league title in 2008/09 before moving through the Hampshire football pyramid and eventually winning the Hampshire Premier Division One title in 2014/15.
After further success, including a 37-game unbeaten run, Infinity were promoted to the Wessex League Division One, although ground-sharing difficulties subsequently forced the club to withdraw.
Following a move to Sidlesham, the club rebuilt and won the Hampshire Premier League Division One title in 2022/23, earning promotion to the Southern Combination League Division One for the 2024/25 season.
Their first campaign at Step 6 proved an impressive one, finishing fifth and reaching the play-offs, where they defeated Godalming Town on penalties before narrowly losing 1-0 to Forest Row in the final. They followed this up with another play off final loss in 2025/26 to Billingshurst.
Infinity have established themselves as an ambitious and competitive side at Step 6 and now play their home matches at The Lumacon Stadium, Sidlesham Memorial Ground.
This season: Infinity FC have played 5 games, winning 4 and losing 1. They sit 2nd in the table on 12 points, 1 point behind leaders AFC Walcountians and 1 point ahead of 3rd place Guildford City.
