Growing up in Maltby, a small former mining town in South Yorkshire, Kirk first got into hockey when his parents and family went to watch the Sheffield Steelers. His brother Jonathan got into ice hockey and Kirk wanted to be like his brother, so he also started playing. Kirk began playing for the Sheffield Junior Academy. He was selected for the Midlands Conference – a team consisting of the best players from the Midlands region of the UK at U11, U13, U15 and U17 level – every year of eligibility, winning the EIHA Conference Tournament twice and being named a tournament all-star six times out of a possible eight, as well as being named tournament MVP three times. Playing in the England U18 North League in the 2015–16 season, Kirk amassed a league-leading 98 points, with 60 goals and 38 assists. The same year, the U18 team from Sheffield won the league title. He was also selected for the Great Britain U16s. Continuing his success as an U18, Kirk played in the EPL for the Sheffield Steeldogs and was signed by the Sheffield Steelers on a three-year apprentice contract. Kirk has represented Great Britain at all age groups. In the 2017–18 season, he played for the U18s, coming away with a gold medal. For the U20s, he collected a range of awards such as Best Forward, Most Points, Most Assists, Most Goals, as well as the Best Face-off Percentage and a bronze medal. Although he didn't get any points, he represented the Great Britain men's team in the Division 1A World Championships. Great Britain won the tournament and were promoted to the top tier of world ice hockey. They now compete against the leading hockey nations such as Canada, USA, Finland, Russia and Sweden.
