I was in the same situation 6 years ago, I was after a particular finish Cherry Wood with wooden worktops in Cork, only two providers and both prices were through the roof. When I was in England I chose the kitchen I wanted, designed it back in Ireland, got Ikea to check my designs and parts list. The kitchen was delivered to my sisters and then I brought back 2 tonne of Ikea kitchen in and on the jeep.
Even with the exchange rate from punt to sterling and travel saved a fortune. The kitchen was far superior than your middle of the range kitchens easy to put together and after 6 years still lasting the time. The great thing is as well you get all the gadets, wire pullout baskets, tall larders, etc. Try the hotdogs as well
Of course with the showroom in Belfast things should be a lot easier now
