Ken Aboh progressed through Norwich City's academy after making his Under-18s debut during the 2021/22 season while still a schoolboy.

The striker signed his first professional contract with the Canaries in December 2021 before stepping up to the Under-21s squad the following season. He made his senior debut in April 2024, coming on as a substitute in Norwich City's 5-0 Sky Bet Championship victory over Rotherham United, and signed a new long-term contract with the club later that summer.

To gain valuable first-team experience, Aboh has enjoyed a number of loan spells in the EFL and National League. He spent the first half of the 2024/25 season with Stevenage before joining Colchester United for the remainder of the campaign, and moved to National League side Boston United on loan in November 2025 as he continued his development in senior football.
