Released from Wolverhampton Wanderers in 2005 without a first-team appearance to his name, Slater joined non-league Chasetown. Helping the "Chase" take Oldham Athletic to a replay at Boundary Park in the first round of the FA Cup in November 2005 was just the beginning of Slater's and Chasetown's cup adventures. By April 2006 he had won a trial with Tranmere Rovers, and was also being looked at by Blackpool and Crewe Alexandra, all English Football League clubs. He helped Chasetown to win the Midland Football Alliance title at the end of the 2005–06 season. He was at The Scholar Ground for the first season of the new Southern League Division One Midlands tier. He came to prominence when playing in Chasetown's 1–0 FA Cup victory over League One Port Vale in December 2007. In doing this he helped Chasetown become the lowest ever ranked club to reach as far as the Third Round of the FA Cup. Vale was the eighth club Chasetown had vanquished in their campaign that season. In his three years at the club he had played 146 league games for the "Scholars", scoring one goal.
Port Vale
He was signed by Lee Sinnott's Port Vale, along with Chasetown teammate Kyle Perry, in January 2008 for a nominal fee and gave up his day job as a block paver. He made his League One debut as a 70th minute substitute in a 2–0 defeat to Swansea City on 19 January 2008. He played four further league games that season, all of them defeats as the Vale were relegated into League Two. After appearing in six league and two cup games for the "Valiants" in 2008–09, Slater was released from his contract in mid-November, and subsequently re-joined Chasetown.
Return to Chasetown
Slater was once again a key member of the Chasetown team, playing 33 games in the 2008–09 season, as they reached the play-off final, only to lose out 1–0 to Nuneaton Town. He played another 35 league games in 2009–10, helping the club gain promotion out of the Northern Premier League Division One South via the play-offs with a 1–0 win over Glapwell. He remained at the club throughout 2010–11, as the club competed at the seventh level of the English football league pyramidfor the first time in its history. However the "Scholars" could not survive at such a high level, and were relegated in 2011–12. They reached the Division One South play-off final in 2012–13, where they were beaten 2–1 by Stamford. The club finished 12th in 2013–14 and 13th in 2014–15, and Slater exceeded 500 appearances for the club in April 2015. He left the club at the end of the 2016–17 season having broken the club's all-time appearance record.
Later career
Slater joined Midland League side Walsall Wood after being signed by Gary Birch in June 2017. He helped the "Prims" to win the Division One title at the end of the 2017–18 season.
