Kitchen tap replacement

Hi folks,

I am looking to replacing a dripping 2 leaver kitchen tap with a mixer something like the one below:

I think I should be able to manage this task myself but doing a bit of research I have a couple of questions:

• Will taps from Screwfix work just fine with Irish connections or will I need to get some sort of adapter for the flexi pipes?
• Will the above work fine in normal gravity water tank hot water fed system (the specs say "Suitable for High & Low Pressure Systems", so I assume it should work fine)

It is a new build house plumbed around 2016/2017 if that helps. Any pointers would be great and appreciated!
