@SciFiScream
I'm in a discussion about this for my son's school.
I've used the for women.scot pro forma letter to request information
Sorry for opening a zombie thread. I may need back up!
Could this help you,
@SciFiScream? I know it's a UK government consultation, but it lays out important principles, and not everything can be devolved to the Scottish government!

In recent years, there has been a trend towards the removal of well-established male-only/female-only spaces when premises are built or refurbished, and they have often been replaced with gender-neutral toilets. This places women at a significant disadvantage. While men can then use both cubicles and urinals, women can only use the former, and women also need safe spaces given their particular health and sanitary needs (for example, women who are menstruating, pregnant or at menopause, may need to use the toilet more often).
Women are also likely to feel less comfortable using mixed sex facilities, and require more space.
[then, further down]
The government wants to ensure dignity and respect for all. The Equality Act provides that sex, age, disability and gender reassignment are protected characteristics. This does not mean that gender-specific toilets should be replaced with gender-neutral toilets. But there should be balanced consideration of how the needs of all those with protected characteristics should be considered, based on the mix of the population and customer demand.
Some of those points may refer to caring responsibilities and of course menopause won't affect schoolgirls at your school (may affect teachers, but presumably they have their own facilities, separate from those used by the pupils?). Depending on whether your son's school is primary or secondary, the protected characteristic of maternity may also have to be considered in an impact assessment.
Religion, too, if there are any Muslim kids there.
Hope this helps?
