In the 2015–16 season saw Carrington continued to recover from a groin injury and made his first team return on 29 August 2015, coming on as a substitute in a late minute, in a 3–1 win over Halifax Town. Though he remained at the bench in handful of games since his return, Carrington scored his first Wrexham goal of the season to score only goal of the game, in a 1–0 win over Torquay United on 5 December 2015. On 26 January 2016, Carrington then received a red card after a second bookable offence, in a 1–0 loss against Braintree Town. After serving a match suspension, Carrington regained his first team place towards the end of the season and went on to make thirty–two appearance in the 2015–16 season. At the end of the 2015–16 season, Carrington was offered a new contract and signed a one–year contract with Wrexham on 13 May 2016.
