At the annual meeting, South Lincolnshire and Border League winners Spalding were automatically promoted and bottom side Nettleham returned to the Lincolnshire County Cricket League, while 11th-placed Grimsby Town retained their Premier League status.
However, having lost a large number of top players at the end of the season, Skegness became aware they would have difficulty fielding a side of Premier League strength and notified the league they would have to withdraw.
This opened the way for Alford CC to be offered - and accept - a place in the league, Nettleham having decided they would prefer not to be re-instated.
Alford finished second in the LCCL, but the strict ECB criteria for Premier Leagues meant that winners Cherry Willingham were unable to be promoted.
Alford and Spalding – who have returned to the top flight only one year after demotion – will now contest the ECB Premier League alongside Boston, Bracebridge Heath, Bourne, Grantham, Grimsby Town, Louth, Lindum, Market Deeping, Sleaford and Woodhall Spa.
