Omoregie progressed further in 2014 season, starting with a third place at the British Indoor Athletics Championships in the 60 metres hurdles (in a personal best of 7.82 seconds). Over the junior hurdles, he ran 7.50 seconds indoors, which equalled the World indoor junior record of Konstadinos Douvalidis. Outdoors, he won the 2014 British U20 Championships with a European junior record of 13.17 seconds for the 99 cm hurdles event. This was later beaten that year by Wilhem Belocian of France. He came up against his rival at the 2014 World Junior Championships in Athletics and, though Belocian won, Omoregie took the bronze medal. Over the senior height hurdles, Omoregie set a best of 13.53 seconds that year and was the winner at the Welsh Athletics Championships.
