From September to October Northern Ireland's rents rose by 0.9%, faster than in London (0.8%) and the rest of England (0.5%).
Despite the significant uplift rents still averaged £562 in Northern Ireland, far cheaper than the UK average of 1,294.
UK rents rose by 0.7% from September to October – defying market expectations for a slowdown between the months.
John Goodall, co-founder and chief executive of Landbay, said: “Seasonality has always been a strong feature of the UK’s rental market so the fact that it appears to be declining in influence is a powerful sign of the increasing strain the private rental sector is under to house the UK population.
“The simple fact is that more people are renting for longer and there aren’t enough properties to meet demand. Now that the economy is improving and wages are rising, people are willing to compete for rental properties, pushing up prices."
UK rents are still somewhat being driven by London and the South East, as rents in the capital increased by 4.1% year-on-year to average £2,063 while rents in the South East rose by 3.4% to £1,033.
The biggest annual rent increases took place in Luton (10.4%), Swindon (9.7%), Southend on Sea (9.7%) and Medway (9.1%).
