The 2004 Formula BMW UK season was the inaugural season of the British Formula BMW championship for young drivers making the transition to car racing. The series supported every BTCC round apart from round nine at Rockingham which supported the Days of Thunder championship. Tim Bridgman won the championship with his small family fun team after scoring in every round. Ayrton Senna's nephew Bruno Senna also took part in the championship towards the end of the season.
