No matter what policy you take out you need to read the full policy. One of the things I find annoying is that some brokers, both in Ireland and the UK, and some of the companies (on their websites) only offer a summary before you actually take out the policy. This is not good enough especially now that you can't assume that anything is covered without checking that there are no unexpected conditions attached.
Last year, from an Irish broker, I found that frost damage was covered i n the policy they recommended (provided via Lloyds) but with 500 euro extra excess. The summary cover, provided by the broker, did not mention the extra excess.
Easily the the most comprehensive cover I was offered last year with the fewest conditions was via a UK broker but it was by far the most expensive - sometimes you get what you pay for! This year they no longer provide cover in Ireland - probably because they had too many claims! I would have used them this year as they did not have the standard unoccupancy clause.
