From the start of the 2007/2008 season referees have had the right to cancel a game where they may consider goal posts to be unsafe. The term unsafe covers several different aspects, as follows:
Goal Posts without the appropriate British Standard (those made before 1996)
Home made football goals.
Goal Posts with metal hooks, to attach the net.
Goals with square posts
Damaged football goals or goals deemed unsafe.
Goals in a general state of disrepair.
This applies to Mini Soccer Goals, Junior and Adult Goals.

The Soccer Store sells a range of Steel and Aluminium goals, as well as a full range of Samba Goals which all comply to the relevant British Standards.
