I would like to create a map like the following:

enter image description here

It displays the 100km grid square systems used by both UK and Ireland.

I have created the 100km grid squares using the TomBio tools plug in, however, the issue I'm having is with finding a projection over both the UK and Ireland that ensures the grid squares align up as in the image above with neither Ireland of UK rotated such as in the image below, which happens when using either 27700 or 29902. Is this possible?

    In the map you show the grids do not align north. They just align up. ordnancesurvey.co.uk/blog/2019/03/… Nov 8, 2019 at 11:47

    Yeah, I should have worded that better, have edited to make that clear

    You could create a new grid, like BNG, just move the origin
