Collins joined Havant & Waterlooville for the rest of the season, quickly impressing the fans[4] and signing a full contract with the club in May 2005.

[10] After being released by Eastleigh, Collins signed for Sutton United at the start of 2015, making 19 league appearances in the second half of the 2014–15 season and scoring his first goal for the club in a 2–1 victory against Basingstoke Town on 11 April 2015.

[13] Sutton supporters unofficially voted Collins player of the month for September 2016[14] and again (now officially as a re-instituted award) for October 2016.

Collins made his 100th career appearance for Sutton on 3 December 2016 in a 2–1 win against League Two club Cheltenham Town in the 2nd round of the FA Cup.
