Customers who receive the Fuel Allowance will have the option to receive the payment in two lump sum payments this year.
The Department of Social Protection has said the change will allow people to save money by buying in bulk.
The rate of payment is €22.50 per week which amounts to €585 per fuel allowance season.
A study they carried out suggests it is 11% more expensive to buy kerosene in small amounts compared to a large purchase.
They have also suggested people will be able to get coal €3 a bag cheaper if they buy in bulk.
