The news follows a competitive 6-way pitch.
Consolidated PR will replace the incumbent agency BGB, which held the account for a number of years.
Consolidated PR will be targeting consumer media with a brief to develop and implement a strategic PR plan that supports the value of a holiday in Ireland.
Consolidated PR head of consumer Liz Fay said: ‘The country has a wonderful variety of experiences for British visitors so our job is to demonstrate the difference and magic of a holiday in Ireland as well as the great deals that are available. This will mean achieving cut-through in and out of travel media.’
