Can my child play up an age group, or for more than one team?

Playing up. A player can play in their own age group and any older one, but each age group has a minimum age:

More than one team. An under-18 player can be licensed for at most two teams at once, across all competitions (Junior NBL, Senior NBL and the British championships). The two teams must be in different age groups or competitions. They can change during the season through an intra-club transfer.

A junior player whose club also has a "parent" senior team may only play senior National League basketball for that senior team.

Fielding a player who breaks these rules means the fixture is forfeited and the club is fined.
