Is there a specific bank balance that a club must have before improving
youth or training facilities?

When interacting with the board to improve youth or training facilities,
is there a specific bank balance that the club must have in order to
improve?
For example, does the club need a bank balance of £X to improve from
"basic" to "adequate" and £XY to improve them to the next stage?
