The Prince and the Homewards project, run through the Royal Foundation, is taking inspiration from Finland, considered a global leader in the field.
It has a network of advocates around the UK to help identify how and where Homewards can best help.
One, Sabrina Cohen-Hatton, who experienced homelessness as a teenager and is now chief fire officer for West Sussex Fire and Rescue Service, suggested the prince had empathy for rough sleepers because of his own life experiences.
His mother Diana, Princess of Wales, took him to homeless shelters as a child to help broaden his horizons.
“He understands trauma, he does understand trauma,” said Ms Cohen-Hatton.
“He can see echoes of it in himself I think, from that experience of trauma and how it affects you and how it affects the way you see things.”
She has recently visited Windsor Castle along with a former long-term rough sleeper called Wayne, who told the Prince how he had turned his life around.
Moving from “managing to ending” homelessness was essential, he said, along with identifying the types of people most at risk of losing their homes.
