The National Development League formerly called the National League was formed in 2009 as the third division of speedway in the United Kingdom, replacing the Conference League. It follows the same rules and regulations as the SGB Premiership and SGB Championship, including the use of rider averages. It is however regarded as the league for junior riders or in some cases other riders returning to the sport.
