Logan joined Luton Town on loan for six months in the 2008–09 season, providing competition for Luton goalkeeper Dean Brill. He saved three penalty kicks in a 0–0 FA Cup draw against Altrincham on 21 November 2008, which Luton won 4–2 on penalties. Logan helped the club to another penalty shootout win against Brentford in the Football League Trophy second round on 7 October 2008. His form prompted the club to make an offer for his loan to be extended by a further month. However, this was rejected by Logan's agent, and he missed out on the 2009 Football League Trophy Final against Scunthorpe on 5 April 2009, which Luton won 3–2.
