Don't know about lodging savings - we have a mortgage with them and find customer service excellent. They seem to be transparent, always respond with required information in a timely manner, and are quite prepared to use modern technology to communicate with you (they have a very good secure email system with clients). So, hopefully you've researched the market in terms of deposits - if you're happy with the return from KBC, then I'd go for it.
I opened an 18 month fixed term account with Investec. Good service and good rate. They also are probably the only financial institution in Ireland who gave a Christmas present to their customers - a nice coffee table book, I am of Ireland, containing the poetry of W.B. Yeats and beautiful paintings by his contemporaries.
