Cook is a graduate of the Bath Rugby Academy, having made his academy debut back in 2009.
The quick-thinking scrum-half, an Old Millfieldian, spent much of the 2013/14 season on loan at London Welsh in the Championship. He was at the heart of the Exiles' successful promotion to the Aviva Premiership.
Seven months earlier, Cook had helped Bath United lift the Aviva A League title at Franklin's Gardens.
In January 2019, he signed a new contract with Bath Rugby, which took the scrum-half into his 11th season with the Club.
Cook had made 123 appearances in Blue, Black and White going into the 2019/20 season.
In May 2020 Bristol Bears signed the scrum-half from Bath ahead of the 2020-21 Premiership campaign.
