Good morning,
thank you both for your replies and advise. With regard to the contract between my agency and the main contractor (based in a EU state other than Ireland) the contract would primarly be to to supply construction workers, the main contractor is required to have employers liability for all workers for all workers on site including agency workers.
However I would also be required to show that I have employers liability to cover construction workers provided by my agency.
I realise that I will also need public liability with regard to the office premises ect, and employers liability to cover office / admin staff.
I have contacted a few insurance companies and I am waiting for them to get back to me. I will keep you updated, many thanks.
