A professional since 2019, Cooper signed a promotional contract with Frank Warren's Queensbury Promotions two years later.[3]
Unbeaten in his first six pro-fights, he dethroned Midlands Area welterweight champion Jamie Stewart on points at the International Centre in Telford on 19 November 2022.[4]
Cooper faced WBO European welterweight champion Eithan James at Resorts World Arena in Birmingham on 16 March 2024, with the vacant English welterweight title also on the line. He knocked his opponent to the canvas in the first round and won when James retired at the end of round nine.[5][6]
He lost his WBO European title in his first defense when he was stopped in the final round by Ekow Essuman at Manchester Arena on 20 July 2024. Although his English championship was not up for grabs, the defeat also saw that title made vacant due to British Boxing Board of Control rules regarding losses to other English fighters in non-title bouts.[7][8]
Cooper returned to winning ways in his next outing, defeating Chris Kongo on points in a 10-round contest at Nottingham Arena on 10 May 2025.[9][10]
He challenged Commonwealth welterweight champion Constantin Ursu in Derby on 28 February 2026, with the vacant British welterweight title also on the line.[11] He lost via unanimous decision.[12][13]
