What do I need to know as a parent of a Basketball England Junior National League player (Under 12 to Under 18)? Age groups, leagues, playing time, ball sizes, defence rules, officials, injuries and conduct for 2026/27.
Junior age groups are set by date of birth, with ages taken at 1 September 2026:
| Age group | Born between |
|---|---|
| Under 18 | 1 Sep 2008 and 31 Aug 2010 |
| Under 16 | 1 Sep 2010 and 31 Aug 2012 |
| Under 14 | 1 Sep 2012 and 31 Aug 2014 |
| Under 12 | 1 Sep 2014 and 31 Aug 2017 |
Players born before 1 September 2008 are in the older categories (Under 21, Under 23 and Senior), which play in senior competitions. A player with a particular need can apply for an exception under Basketball England's Eligibility and Participation Exemption Policy, with supporting evidence.
Playing up. A player can play in their own age group and any older one, but each age group has a minimum age:
| Age group | Youngest players allowed |
|---|---|
| Under 12 | School Year 5 (turning 10 from 1 September 2026) |
| Under 14 | School Year 6 (turning 11) |
| Under 16 | School Year 8 (turning 13) |
| Under 18 | School Year 10 (turning 15) |
| Senior | Must already be 15 |
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.
Two things, both arranged through the club on Basketball England's online registration system:
Basketball England normally processes a complete licence application within seven business days, and may ask for extra documents, such as a transfer request if your child is moving from another club (a parent or guardian must request this for players under 18) or international clearance if they were registered with a federation outside England.
Fees are non-refundable once the season has started. eScoring is mandatory in the NBL, so only eligible, licensed players can be added to the scoresheet.
The Junior NBL has Under 18, Under 16, Under 14 and Under 12 leagues, with boys' (or men's) and girls' (or women's) competitions, plus an Under 12 Mixed league. There are also Under 18 and Under 16 national cups.
| Level | Format |
|---|---|
| Premier (Under 18, 16, 14) | Divisions play each other home and away, then end-of-season playoffs |
| Conference (Under 18, 16, 14) | Divisions play home and away; the division winner takes the title. The top Conference teams play the lowest Premier teams in a promotion playoff |
| Regional (Under 16, 14) | Divisions play home and away; the division winner takes the title |
| Under 12 | Divisions play each other once (single fixtures) |
Some rules (zone defence, pressing and All Must Play) differ between these levels, so check which level your child's team is in.
Junior NBL games are played under the FIBA Official Basketball Rules unless Basketball England's regulations say otherwise:
Games are normally played on Saturdays or Sundays, and the court must be available for warm-up 20 minutes before tip-off.
In some leagues, yes: Basketball England's All Must Play rule applies in Under 12 Girls, Under 12 Mixed, Under 14 Girls Conference, Under 14 Boys Conference and Under 16 Boys Regional. It doesn't apply in promotion playoffs or cup games between a Conference team and a Premier team. In other leagues, playing time is the coach's decision.
How All Must Play works:
A team that plays a fixture with fewer than 8 players can be fined.
It depends on the age group and level:
Zone (or combination) defence
Full-court press
When a Conference team plays a Premier team in a playoff or cup game, the higher league's rules apply, so zone and pressing are allowed throughout.
Basketball England uses an in-game sanction, applied by the referees:
All National League games must use Basketball England's official Wilson match ball in these sizes:
| Age group | Ball |
|---|---|
| Under 18 Boys | Size 7 (Wilson Evolution) |
| Under 18 Girls | Size 6 (Wilson Evolution) |
| Under 16 Boys | Size 7 (Wilson Evolution) |
| Under 16 Girls | Size 6 (Wilson Evolution) |
| Under 14 Boys | Size 6 (Wilson Reaction Pro) |
| Under 14 Girls | Size 5 (Wilson Reaction Pro) |
| Under 12 Girls and Under 12 Mixed | Size 5 (Wilson Reaction Pro) |
Teams bring their own practice balls, which must also be the relevant Wilson official game ball. The crew chief approves the match ball at least 20 minutes before tip-off, and a ball from a different competition can't be used.
The home club appoints the referees and table officials, to these minimums:
| Competition | Referees |
|---|---|
| Under 18 and Under 16 Premier and Conference, Under 14 Premier | 2 referees at Level 2 or above |
| Under 16 Regional, Under 14 Conference and Regional, Under 12 | 1 at Level 2 or above plus 1 at Level 1 |
Table officials (including the shot clock operator) range from two Level 1 officials at Under 12 games to three officials (Level 3+, Level 2 and Level 1) at Under 18 and Under 16 Premier games.
Rules for home-appointed referees:
Basketball England may appoint the crew chief itself, and appoints neutral referees from the playoff quarter-finals and junior national cup semi-finals onwards. If a home club breaks these rules, the game is forfeited to the other team and the club is fined.
For Basketball England's National League competitions (including the Junior NBL):
Players. Under the FIBA rules, a player who reaches 5 fouls must leave the game. A player is disqualified for two flagrant fouls, two category 1 technical fouls, one of each, or a disqualifying foul.
When a Junior NBL player (of any age) is disqualified, a coach or bench person licensed to that team and club must take them out of the sports hall and stay with them. If nobody is available, the player must stay in the hall on the opposite side of the court from their bench and must not communicate with either team or the officials. Any further incident is taken into account in a later disciplinary investigation.
Coaches. If a coach is disqualified and no suitably qualified, licensed assistant coach is listed on the scoresheet, the game is stopped and the team loses by default. If the other team was ahead, the score at that point stands; otherwise the result is recorded as 2-0 to them.
Junior NBL teams are expected to travel with at least two appropriate adults, in line with Basketball England's Safeguarding Policy.
Bleeding: the referees must send any player who is bleeding or has an open wound off the court. They can come back only once the bleeding has stopped and the wound is completely and securely covered.
Head injury: if a player shows signs of a head injury, the referees must stop the game straight away, whichever team has the ball and wherever it is. A player showing signs or symptoms of concussion must be taken out of the game by their coach, and coaches must follow Basketball England's concussion guidance.
Yes. Spectators may not use air horns (including vuvuzelas) or whistles at Junior NBL games. The crew chief (lead referee) has the authority to stop the game and tell the game day delegate or home team to remove them.
