What do you mean "up for renewal"? Do you mean that you are coming to the end of a fixed rate period and need to choose another fixed, variable or tracker rate? Or do you mean that you have approval in principle which is due for review given the time that has elapsed since you originally got it?
Your lender will probably write to you outlining some of the rates on offer at the end of the fixed rate period. They may not list them all especially the best value tracker rates. That was my sister's recent experience with EBS (the mutual that gives such a great deal to its members and all that...
) and only that she asked me she would not have known about their ECB + 1.2% (< €250K, < 60% LTV) tracker which is the best rate on offer from them for her specific circumstances. (Even if there were better trackers available elsewhere the amount and term outstanding on her mortgage would not make switching worthwhile).Make sure that the list is exhaustive. It may not be.
You might want to also post some details of your mortgage - e.g. amount and term outstanding, approximate value of house etc. since stuff like loan amount outstanding and LTV ratio may be pertinent to saying what rate is or is not competitive.
I would say almost certainly not.
