Making extra payments towards your mortgage can be an effective way to reduce your mortgage balance more quickly, but it’s not always the right option for everyone. Before making mortgage overpayments, it’s important to understand your lender’s rules, whether any early repayment charges (ERCs) apply and how overpayments could affect your financial circumstances. In this guide, we’ll explain how mortgage overpayments work, the potential benefits and the factors you should consider before making extra payments.
Mortgage overpayments reduce the amount you owe on your mortgage.
Some lenders limit how much you can overpay each year without an early repayment charge.
Overpayments may reduce the total interest paid over the life of the mortgage.
The most suitable approach depends on your financial circumstances and mortgage product.
It's worth checking your mortgage terms before making any overpayments.

What Is a Mortgage Overpayment?
A mortgage overpayment is any payment you make above your normal monthly mortgage payment. By reducing the outstanding mortgage balance, overpayments may reduce the amount of interest charged over time, depending on your mortgage terms.
What Are the Benefits of Making Overpayments?
Making mortgage overpayments may:
- Reduce your mortgage balance more quickly.
- Potentially reduce the total interest paid over the mortgage term.
- Shorten the length of your mortgage if your lender allows.
- Increase the equity you hold in your property.
The outcome depends on your lender’s terms and how overpayments are applied.
Are There Any Drawbacks?
Potentially. Some mortgage products include Early Repayment Charges (ERCs) if you exceed the amount you’re allowed to overpay. It’s also important to consider whether keeping savings available for emergencies or other financial goals may be more appropriate for your circumstances.

How Much Can I Overpay?
Many mortgage lenders allow borrowers to overpay up to 10% of the outstanding mortgage balance each year without an ERC, but this varies between lenders and mortgage products. Always check your mortgage offer or speak to your lender before making large overpayments.
Will Overpayments Reduce My Monthly Payments?
Not necessarily. Depending on your lender, overpayments may reduce your monthly payments, shorten your mortgage term or be applied in another way. The outcome depends on your lender’s policy and your mortgage agreement.
Should I Overpay My Mortgage or Save the Money?
There’s no single answer. The most suitable option depends on factors such as your mortgage interest rate, savings interest rates, emergency fund and wider financial goals. You may wish to consider independent financial advice if you’re unsure what’s appropriate for your circumstances.
Can I Stop Making Overpayments?
In many cases, yes. If you’re making voluntary overpayments, you can usually stop them, although the options available depend on your lender and how the overpayments are arranged.
Should I Speak to a Mortgage Broker?
If you’re considering overpayments or approaching the end of a fixed-rate product, a mortgage broker can explain how overpayments may affect your mortgage and discuss whether reviewing your mortgage arrangements could be appropriate.
