Born in Camden, London, Regis was on the books at Arsenal until his release in 2012. He completed his two-year scholarship with Southampton in 2015, before being released. He signed a development contract with Colchester United after a successful trial spell in August 2015. He joined Isthmian League Division One North side Maldon & Tiptree on a month-long loan deal on 23 February 2016. He made his debut that same day, and scored within just three minutes of a 2–2 draw with Dereham Town. He went on to make a total of five appearances for Steve Ball's "Jammers". Regis signed a one-year contract extension with Colchester in May 2016, but left the Colchester Community Stadium by mutual consent in January 2017 without making a first-team appearance. Regis joined Isthmian League Division One South side Sittingbourne in March 2017. He started 2017–18 season with Farnborough, making his debut in the opening day 1–0 victory at St Neots Town on 14 August. He played a total of five Southern League Premier Division matches and one FA Cup game for the "Yellows", before he departed Cherrywood Roadin September.

Port Vale
On 7 November 2017, Regis signed for League Two side Port Vale until the end of the 2017–18 season, having impressed on a trial basis. He scored on his debut the same day in the club's EFL Trophy game, just four minutes into a 4–2 victory over Crewe Alexandra at Vale Park. He had been scouted by the club's football advisor John Rudge, who had spotted him during his unsuccessful trial spell at Bolton Wanderers. However manager Neil Aspin soon criticized the player's attitude, saying that Regis failed to warrant even a place on the bench "because his attitude and everything outside of the football has not been good enough". Aspin allowed Regis to leave and find a new club in April 2018.
Non-league
On 31 July 2018, Regis joined newly-relegated National League South side Torquay United. However he left the club for National League South rivals Wealdstone on 6 November after "Gulls" manager Gary Johnson told him he was not in his first-team plans at Plainmoor. However he featured just once for the "Stones". He signed with Truro City on 22 March 2019. The "White Tigers" were relegated at the end of the 2018–19 season.
International career
Regis was selected to play for the England under-17 team in a friendly tournament in Tórshavn, Faroe Islands in August 2012. He played four matches, and scored one goal against Finland.
