You need to bear in mind the maximum compensation limit of �50,000 per person for absolutely safety. You also also need to be aware that many savings institutuions which you might think to be independent operate under the same FSA licence as others in their group. Check out :
http://www.moneysavingexpert.com/savings/safe- savings#whatcounts which lists which institutions are linked together. I believe the government was thinking of increasing the amount of savings protection for short-term deposits of large sums of money. There might be an announcement in the April 22nd budget, but don't bank on it.
Also check out the Savings section on the moneysavingexpert.com website which lists the best savings deals. Interest rates are pretty dismal at the moment, and because the Irish economy is in dire straits, I suggest avoiding any Irish financial institutuions.
