Before making overpayments, talk to your lender to understand if any early repayment charges apply. If you want your overpayments to have the effect of reducing your mortgage term, rather than reducing your monthly payment, you need to talk to your lender.

Overpayments won’t automatically reduce your mortgage term or your monthly mortgage payment, but could save you money by reducing the amount of interest charged. When the next monthly payment recalculation happens, for example at an interest rate change, the monthly payment will be calculated using the existing remaining term of the mortgage.

Compare mortgages

It’s important to look at all your options to find the right mortgage for your circumstances.

When you apply for a full mortgage, it can affect your credit rating and leave a mark on your credit history that other lenders can see.

But you can use a search (like ours) that lets you compare a range of mortgages that you’re likely to be accepted for before you apply.
