Can't help with your query but can recommend my own broker - David Pike (Ph. 01 7096000, david@pike.ie) - a very experienced general insurance broker. No connection other than a happy client.
We had the same problem when we purchased a catering unit over 2 years ago - couldn't get insurance.
Someone on this forum put us on to a broker - Robert Tyrrell of Campion Insurances Ltd. They're based in Cashel and tel no. is 062 - 61991
I can't remember who they got us insured with and I can't put my hand on the insurance docs at the moment, but it's worth giving him a call to see if he can help you.
