When your fixed-rate mortgage term ends, there are some options to consider. Firstly, you can stay on your lender’s Standard Variable Rate (SVR) mortgage, or you can remortgage with a new deal - either with your current lender or a new one.
If you do nothing when your term ends, you will automatically switch to your lender's SVR - these are generally higher than fixed-rates, so your monthly payments are likely to increase.
If you choose to seek out different remortgage rates, you’ll need to find a new mortgage product, either variable or fixed, and move your mortgage balance to it. This is an opportunity to move lenders, and is a chance to secure a potentially lower interest rate.
