A friend uses national irish bank- they have lower rates than davies.
does ulster bank have any wing that do share dealing (days are linked to AIB, which is the way I use...)
In general i think one has to take some sort of hit when selling shares, it's a matter of taking the smallest hit. But not 100% on that but i'd be surprised if there is a cost free way to sell. Plus you'll have to pay some sort of caoital gains tax, i imagine too
