Beware of lenders who offer attractive discounted rates to new customers but are not competitive on the normal rate that will kick in from year two or whatever. Better to look at the long term cost of the loan than short term discounts. Also - only fix if you really need to and not in an attempt to time the market, second guess the institutions and save money over a competitive tracker/variable rate. You generally won't. And remember that fixed rates are inflexible and involve penalties if you decide to clear or reduce the mortgage before the term is up or move house.
