More than half of private renters who contacted Threshold last year were at risk of becoming homeless.
12,000 households got in touch with the housing charity for the first time last year, with a total of almost 20,000 private tenants reaching out for help.
The charity's annual report for 2021 found tenancy termination remained the top concern for renters for a fifth consecutive year.
CEO John-Mark McCafferty says it assisted 19,947 households in 2021;
"Our advisors supported this stark number of households with over 22,000 issues, meaning that some households faced two separate challenges in their private rental accommodation in the space of 12 months and required Threshold’s advice or help to deal with these."
He says the not-for-profit encountered a larger level of queries concerning standards and repairs compared to previous years, with 10% of private tenants seeking advice on their accommodation.
In 2021, Threshold advisors represented 255 households at the Residential Tenancies Board (RTB) and assisted 291 households to submit disputes.
