During the 2014–15 season, Qualter again did not feature in the Pro12 campaign, but did make three appearances in the new Rugby Challenge Cup. In his first senior appearance of the season, Qualter was used as a back row replacement against Exeter Chiefs in a 33–13 defeat. On 13 December 2014, Qualter made his first senior start for Connacht, playing as the number 8 and lasting the full 80 minutes in a 27–29 away win over Bayonne. Qualter was used as a replacement lock in the final pool game against La Rochelle, with the 20–30 victory earning Connacht a place in the knockout stages. It was announced in May 2015 that Qualter had signed another one-year extension to his contract with Connacht to keep him with the team until the end of the 2015–16 season.
