There are no properties available to rent within the standard rate Housing Assistance Payment (HAP) for the first time ever, according to new figures released by the Simon Community.
Overall, there are just 35 properties available for people reliant on HAP, according to Simon's 'Locked Out of the Market' report.
HAP is a social welfare support for people who have long-term housing needs. It is operated by local authorities.
The Simon Community has described the payment as useless, given the current state of the rental market.
Speaking on Newstalk Radio, Simon Communities Head of Policy, Wayne Stanley, backed calls for an eviction ban.
"I think we're at a stage where that's an imperative," Mr Stanley said.
"In and of itself, it's not an answer to this crisis, but what it will create is breathing space.
"What we are seeing is currently 3,220 children in homelessness.
"During the moratorium on evictions during the Covid period, we saw a fall particularly in family homelessness. We hope to see that replicated," he said.
Mr Martin confirmed on Sunday that he expects Mr O’Brien to bring proposals to Cabinet soon and signalled the energy crisis could see it introduced.
