At the end of each season a Playoff is held if a team wishes to join the League. The team finishing bottom in each season will take part in a play off with any team from within the County Association who have won their respective first division league and whose green they have won the league must have floodlights. Where the application is from a club whose green is located outside the Shropshire county boundary, the application will only be considered if the club is solely affiliated to the Shropshire County Bowling Association and they have been affiliated for a minimum period of 10 years.
If more than one team wishes to join the league then these teams playoff against each other (either in a round-robin or knockout) to decide who should take on the botom placed team.
The playoff final is one of the most watched games in the country and takes place on the first Friday in October.
