The club spent three seasons in the National Conference League Premier Division between 1993 and 1996. David Ellis coached at the club during the 1993–94 and the 1994–95 seasons. A move to the National Conference League saw the club narrowly miss promotion to the professional ranks in 1993. In 1994, Hemel played London Broncos in the Regal Trophy, leading 18–6 at half-time only to succumb in the final 10 minutes. The club's playing depth that day was emphasised when, in the curtain-raiser, its reserves won the Southern Counties Cup against the all-Kiwi South London Warriors.
