Despite winning five caps for the full England side, Regis never played the full 90 minutes for his country at senior level; he played as a substitute three times and was himself substituted twice.
Til trods for at han deltog i fem landskampe for det engelske A-landshold, nåede han aldrig at spille alle 90 minutter for sit land på højeste niveau; han spillede som en indskiftning tre gange, og blev selv udskiftet to gange.
