Should you overpay your mortgage?

Overpaying isn't necessarily the right option for everyone. Before making additional payments, it's important to check your mortgage terms and whether your lender applies any early repayment charges or limits on the amount you can overpay.

You should also consider whether keeping your money in savings, reducing other debts or using it elsewhere could be more appropriate for your circumstances.

If you're considering overpaying your mortgage, we can help you understand your options and whether it makes sense as part of your wider financial plans.
