Making Mortgage Overpayments

Overpaying your mortgage can save you thousands in interest and help you repay your loan faster. But it’s important to understand how overpayments work — and what limits apply.

What is a mortgage overpayment?

  • An overpayment is any amount you pay on top of your agreed monthly mortgage payment.

  • Overpayments directly reduce your outstanding loan balance, meaning you pay less interest over time.

Benefits of overpaying:

  • Pay off your mortgage sooner

  • Save significant amounts of interest over the long term

  • Reduce monthly payments in the future (depending on your lender’s terms)

How much can you overpay?

  • Most lenders allow overpayments of up to 10% of the outstanding balance per year without penalty while on a fixed or discounted deal.

  • Unlimited overpayments are usually allowed if you're on your lender’s standard variable rate (SVR).

Are there any risks or downsides?

  • Early repayment charges (ERCs) may apply if you exceed allowed limits.

  • Always ensure you keep emergency savings accessible before tying up funds in overpayments.

  • Overpaying may not always be the most effective option if you have higher-interest debts elsewhere.

We’ll help you calculate how much you can safely overpay, check your lender’s rules, and assess whether overpayments fit within your broader financial plan.
