We recommend reviewing your options 6 months prior to your current deal expiring. It is at this point where you should seek expert remortgage advice. It is not a given that your existing Lender will have the best deal on the market, and if they don't, it will only benefit you in the longterm to have someone guide you through this process and secure the best mortgage deal moving forwards. As whole of market advisers, we are able to switch your mortgage to the best deal possible as we are not tied to one lender. If you do not secure a new deal, you will automatically revert to the lender Standard Variable rate, typically between 4-5%.
