Transport Minister, Paschal Donohoe, says there will be no change to the administration of Irish Water this year.
It follows reports that the Government is considering restricting the €100 water conservation grant to those who actually pay their bills.
The Department of the Environment also said Environment Minister Alan Kelly is not bringing any measures to Cabinet on the issue.
Currently it is available to everyone who has registered with the utility, meaning even customers who do not pay their bills will still get the grant.
But Minister Donohoe said, while all measures at Irish Water are being kept under review, there will be no change to the structures already in place this year.
He said: “What you’re talking about here is speculation in relation to decisions on proposals that have not even been brought to Cabinet.
“It is absolutely necessary that as a Government, we keep all measures relating to Irish Water under review.
“The structures that are in place now in relation to charging and in relation to the conservation fee are in place, and will be in place, across this year.”
