To me this looks like crowd-funding for lawyers and counsellors. To help them to move the homeless on more quickly to Housing Associations, local Councils and other tax funded institutions.
Shelter is basically a charitable organisation that supports people who are homeless, vulnerably housed, likely to lose their homes, living in dreadful conditions, etc. I've supported them in the past, when I was working and had more money. Now I just donate a box for a homeless person at Christmas. Similarly I've supported the project run at Sheffield Cathedral for the homeless. Most of the helpers there are volunteers.
I think Brian should pay a visit to Sheffield, and perhaps visit the Archer project. I'm sure the genuinely homeless people would welcome his point of view.
