UK Ltd company billing in Ireland / EUR ? (remote with some travel to Ireland)

Hi all,

I had a chat today with a UK recruitment consultant who has a 12 month fixed term contract working for an Irish company (day rate range is 650 EUR / 560 GBP to 750 EUR / 651 GBP).

The role is remote, but I would need to be in Dublin for a block of 2-3 days per month.

I'm assuming this would be outside IR35 , but how would it work with billing and payments - and which tax laws would I need to be compliant with (UK or Ireland)

Does anyone have experience of this or am I better speaking to an accountant ?

Also, this would be my first consulting gig as a UK Ltd company - all previous roles have been permanent. I've not managed to land another role in 3 months, which is why I'm considering this more seriously as an opportunity.
