The Minister for Transport has said the government is "satisfied" that the tax cut on fuel is being passed on to motorists.
The excise duty on a litre of diesel was cut by 20 cent, with a 15 cent drop for petrol until the end of May due to the surge in oil prices over as a result of the Middle East conflict.
Darragh O'Brien said the government is "monitoring" to ensure that prices at the pumps are reduced but he said he is "satisfied those reductions are being passed on".
"I've already instructed CRU [Commission for the Regulation of Utilities] and the CCPC [Competition and Consumer Protection Commission] to monitor this very closely."
He said he has also been engaged directly with the industry through the sector’s representative group Fuels for Ireland.
Mr O’Brien said if there are cases where people feel the excise cuts are not being passed on, "they should obviously make contact through the CCPC, or indeed, through CRU".
He also said the government will continue to monitor the situation and intervene with further supports if required.
"We will keep this under daily review. I chair the National Energy Affordability Taskforce. We met again this week. We received advice directly from the IEA [International Energy Agency] as well in relation to the outlook."
"This situation is not just changing on a daily basis, it's literally changing on an hourly basis", Mr O’Brien added.
"We will continue to monitor, working directly with the Taoiseach and the Tánaiste and my colleagues across government, to make sure that if and when we need to deploy additional support, that will be done."
'No immediate concerns' on fuel supplies
The Transport Minister also said there are "no immediate concerns" in relation to supplies of fuel, home heating oil or jet fuel.
"Right now, it's not an issue."
Darragh O’Brien said he has been in contact with The National Oil Reserves Agency and other agencies, who he said have "confirmed to me that supply and reserves are in place".
"Our supply through the month of April is steady, but it is something that we are going to have to continue to watch."
"We all earnestly want an immediate de-escalation, but even if it were to stop tomorrow, from a humanitarian perspective we obviously want that to happen, but there is still going to be further issues with regard to pricing because a lot of the supply that Europe has received through the Strait of Hormuz has actually been before the conflict itself actually started".
The Minister said the issue is being monitored from an EU level "to ensure that we have the supplies of gas that we actually require".
