Housing Justice also found that volunteers gave 200,000 hours of their time to help run shelters last year, equalling more than £3m worth of work.
Their figures come after Crisis, another homelessness charity, conducted a separate poll which found 1 in 4 homeless people would be spending Christmas Day alone.
The Rt Revd James Langstaff, the Bishop of Rochester and Chair of Housing Justice, said: "The overwhelming majority, more than 80%, of these projects have at least one Church of England church taking part working alongside others to provide warmth and welcome to those in need".
"I am deeply grateful to those volunteers who give of themselves, providing not only food and shelter but a love of the neighbour."
And Alison Gelder, Chief Executive of Housing Justice, said: "We believe shelter users are all marked with the imprint of God.
"Over the next couple of weeks, homeless people will be welcomed in alongside carols and mince pies."
Premier's contacted churches and Christian organisations across Britain to make a list of events and gatherings for people to go to if they're alone on Christmas Day 2015.
