The following is an A-Z list of riders who are contracted to appear in 2018, at Premiership, Championship and National League level.

NOTE: (1) All entries for the current season are as per the declared team line-ups, but do not necessarily relate to actual appearances for the named clubs, particularly in the case of No. 8s and/or guest riders; (2) The symbol II after a team's name differentiates between a club's National level and higher league side, when more than one team was operated in the same season; (3) With regard to 'Club Honours', riders have been credited with a contribution to a league title-winning side if they rode in 6 or more matches of the team's league programme - and with a cup-winning contribution if they appeared in at least one leg of the final; (4) The Speedway Grand Prix and Speedway of Nations statistics will be updated for participating riders after each round of the 2018 series.
