Money guide Ireland tells you the best card for ATM and taps in non euro which is UK. Revelut have a limit of 200 per month and this further link shows you how much all cards cost for atm withdrawels. My advice would be to use the revelut everywhere and take 200 per month cash as petty cash for emergencies. Just add euro to revelut, exchange the euro to sterling in the revelut app during working hours and tap the bejaysus out of it. Take 200 out every 31 days
