At Allied Irish Bank (GB), we know you can’t truly understand a business by offering a one-size-fits-all approach to banking.


That's why we’re The Single Minded Business Bank. Focused on delivering relationship driven service to medium and large sized business across Britain. 



What Our Customers Say


“AIB (GB) have proved to be a fountain of knowledge for us as a business. We find AIB (GB) human as many banks have automated systems which result in the human touch being lost. AIB (GB) are practical, honest and more importantly approachable”.

Jacqueline O’Donovan, Director of O'Donovan's
