A visit to a fee only planner might well be in order.  My first question however would have been "what are you currently doing with the money you currently are savings (or if retired have previously saved).?"  Not to mention didn't you give this any thought when you first considered moving homes?

If you aren't currently using a planner or adviser to help you manage those funds what is so unique about the surplus funds from a housing change that suddenly requires the help of a planner?  Unless you are solely dependent on a DB pension surely you have experience with other investments?  

But I fully agree that a bank salesperson isn't the best person to be getting advice from.
