Shortly before the end of the transfer window on 31 August 2012, he joined fellow Championship side Huddersfield Town in a loan deal to last until 13 January 2013. He made his Huddersfield début as a substitute in a 2–2 draw at Ipswich the following day, and scored his first goal for the club minutes after coming on as a substitute in a 1–3 loss at Peterborough on 23 October 2012. His only other goal for the Terriers happened to be his final kick of his loan spell with a last minute equaliser against Birmingham City in January 2013. Shortly after, Hammill was recalled by the club.
