Changing firmware on Galaxy S5 from UK to Ireland

[AC Question]

Hey Guys,

I am flashing a Samsung Galaxy S5 after have issues with a factory reset and was wondering if it's ok to use the firmware for Ireland. The phone was originally bought in the UK but is now going to a new home in Ireland.

Phone details:
Model: G900F
CSC-code: BTU
G900FXXS1CQD1

Can somebody point me in the direction of the correct firmware to install? Thanks
