He and Station Officer Steele both trained together at the same Fire Academy, after which they both together started work at the Pontypandy Fire Service.
Boyce later got transferred to Newtown Fire Station, where he climbed up the ladder and eventually became Chief Fire Officer.
He visited Pontypandy after a very long time during The Great Fire of Pontypandy, when he came to present Sam with the Medal of Outstanding Bravery. During his visit he also offered Sam a promotion as Station Officer of the New Rapid Response Fire Unit in Newtown, which was eventually declined by Sam.
He stood in for Station Officer Steele, as a relief when he injured his back.
He also often sent by HQ to conduct drills and assessments for the Pontypandy Fire Station. He tested Elvis's driving for his Advanced Driving Certificate, he tests the teams abilities in multiple rescue scenarios and demonstrates how to perform certain rescues.
