Farmers supplying Glanbia Cheese will receive a 0.5p/litre bonus from 1 July.
The bonus was introduced a year ago and previously paid to those farmers who produced the same as, or more than, they did in the same month a year earlier.
However, from the start of July it will be paid to all producers, regardless of production levels.
The cheese-maker said the bonus was permanent and it had no plans to change it.
Glanbia has around 250 suppliers across the UK,
Suppliers are paid 30.3p/litre before the bonus.
