A spokesman for homeless charity Shelter Cymru said: “We certainly agree that things are getting more difficult for a lot of people for a range of reasons connected with welfare reform, cost of living and low incomes.
“One worrying trend we have identified is the rise in social housing evictions in 2014, which does seem to support Cais’s view that people are running out of options.”
The Welsh government said more than £11m will be spent on tackling homelessness in the 2015/16 financial year.
A spokesman said the latest figures showed an 8% fall in homelessness between April and June 2014, which he described as “promising”.
“In April next year, the Housing (Wales) Act 2014 will come into effect which puts a greater emphasis on preventing people from losing their home and providing better services to those who are homeless,” he added.
