As regards letting out rooms, here is the official Quaker guidance
"Principles"
The letting of rooms in Friends House is undertaken to raise income and to help pay the running costs of the work of Quakers in Britain. It is also a means of introducing Quakerism and Quaker work to a wider audience.
The hirers of rooms are expected to:
I *Respect the Quaker commitment to truth, equality, simplicity, peace and sustainability, and in particular:
not advocate in any circumstances for the use of violence,
not make any statement that denigrates or undermines either the dignity of an individual, group or nation, or the actual or perceived identity pertaining to an individual, group or nation (including, but not limited to, racial and ethnic identity, sex or gender identity, and sexual orientation)*
*Respect the long-held Quaker belief in the importance of people coming together to hear opinions across divides, expressed with due care and consideration for other people’s rights and dignity.
*Respect the aim to manage and operate the building in the most sustainable way.
