The latest Daft.ie rental price report, covering Q3 of this year, shows rents have risen for the 21st consecutive quarter and that the average rent across the country is €1,198 - an 11.2% increase on the same period last year.
A report by Daft.ie shows that rent prices are again at an all time high in the city, rising by 12 percent since previous year.
According to the report which analysed trends during July, August and September the average monthly rent in Limerick city is now €946 while a property in County Limerick will set you back €748.
Further increases where seen in Cork (five per cent), Galway (nine per cent) and Limerick (10.9 per cent).
Ronan Lyons, the author of the research says that the Government's efforts are just simply not enough.
He said: "There isn't a single part of the country where rents are increasing less than 4% a year which is what the rent presure zones are created to do".
"It is not clear to me that the system of rent pressure zones is working, in fact it may be having the opposite effect".
Speaking to RTÉ's Morning Ireland, Mr Lyons said lack of availability is the problem and there has been nearly a halving of available accommodation since the start of the year.
Mr Lyons said it is a countrywide problem, and not just an urban issue.
This thought was echoed by homelessness charity Focus Ireland who say that loopholes in the law allow landlords to raise the rent by more than the four per cent limit.
