The number of people helped by the Peter McVerry Trust was up 30% last year.
The national housing and homeless charity's Annual Repot for 2021 revealed over 10,000 people were now using its services.
It also helped over 1,500 vulnerable people to be vaccinated by the end of last year in response to the Covid-19 pandemic.
CEO Pat Doyle says the charity will continue to meet the demands of the increasing numbers of people who require its support.
"We've worked with over 10,000 people in 2021 that's a phenomenal amount.
"When you think back to kind of 2012 where we were working with 3,000 people and we thought we were doing great.
"The sadness of that is such as more people to work with, and the trust is trying to spread itself and offer itself to as many people who need our support as possible."
