Currently escorting is legal. It is illegal for escorts to share apartments, otherwise it is classed as a brothel. From my understanding, 'raid' is the headline that sells papers, whereas in reality, most of the time, gardai are just knocking on the doors making sure escorts are okay, checking ID and making sure that everything is in order.
The Irish and Northern Irish government are working to make paying for sex illegal, as in the infamous 'Nordic Model' that the Swedish government implemented in the late 90s, boasting that it has eradicated the sex trade in their country. Despite ambiguous, varying statistics to actually support this and an increase in street prostitution.

not illegal at the moment. Obviously if it was illegal, it wouldn't affect your punting habits as you assumed it was anyway
