I would add to my previous response that one of the fundamental go/no go factors ought to be the status of the entity seeking funds for their (otherwise financially unviable) venture.
Are they a ‘charity’ a ‘charitable company’ a ‘charitable trust’ or a Community Interest Company?
You’d need to know ‘what’ they are in order to make a sound decision - can’t remember if s137 requires it to be one, or the other, entity but model standing orders often do
If a charitable company - where staff and directors are salaried - probably NOT eligible.
If a charitable trust - where Chair, trustees and ‘staff’ are volunteers - possibly eligible (whether it’s appropriate or not is a different matter!)
