Our primary school always says that they will support parents with costs if they are struggling. Also I feel that the costs are pretty reasonable for the outdoor centre they normally go to, Mount Cook nr Wirksworth.
It's a question worth asking around about locally as well. There can be some very local funding sources where someone left a load of money to their parish council to support young people from their village going on trips or something like that. The local education authority might be worth asking, they have people who are regularly involved in overseeing the planning of trips.
Not sure if this is applicable as my experience is England based and your profile puts you in Scotland, where things could be very different.
It used to be the LEA. Since there demise it now seems to rely mainly on local charities. Cumbria did have a push a few years ago to fund DoE place for disadvantaged students. There are some national organisations. I have used a company called M7E(?) but if I remember correctly over half the students on the trip had to be pupils premium.
Community Councils sometimes help out with funding school trips, also contact your local authority. Ours administers trusts and bequests where there’s been money left to help out with the funding of such things.
In addition to this, some local businesses can be approached for sponsorship.
The outward bound trust heavily subserdises trips from schools from less economically privileged areas during their quieter winter months. When I worked there some kids and schools came for very low fees. I can't remember exactly by how much, but the charity funds but they pay for a large percentage of the
Amazing charity too whose courses are ace.
Please phone them and enquire their courses are genuinely life changing and they want their centres full. I ran some courses for the poorest of kids and they paid very little if anything to attend.
