Paying extra off your mortgage
What are the benefits of overpaying your mortgage?
Overpaying your mortgage can reduce the amount of interest you pay and help you clear your mortgage sooner if extra payments are applied directly to the capital balance. You can do this by making lump‑sum payments or paying more than the agreed amount each month, but the rules depend on your mortgage type. Variable‑rate mortgages usually allow overpayments without penalties, while fixed‑rate mortgages may charge fees or limit how much you can overpay.
It’s important to tell your lender to apply any extra payments directly to the mortgage balance so you benefit fully. Use the CCPC Overpayments calculator to compare savings, and check whether you need to update your mortgage protection cover if your term changes.
Important
Making an extra payment does not automatically reduce your mortgage balance. If you do not clearly instruct your lender to apply an overpayment to the capital, the money may sit in a credit or suspense account instead. This means you may not reduce your balance or save interest as expected.

Depending on your mortgage type, fixed or variable, you may be able to make extra payments and save money by reducing interest and shortening your mortgage term.
What should you consider if you’re on a fixed rate?
With a fixed rate mortgage, overpaying can trigger significant charges, and the cost and rules vary between lenders and contracts. Some fixed‑rate mortgages allow limited overpayments without a penalty, while others may charge a fee or not allow overpayments at all during the fixed period.
Always discuss this with your lender before making any overpayment, as savings may still be possible in some cases. You should also confirm that any overpayment will be applied directly to the mortgage capital. If you do not give clear instructions, the extra payment may sit in a separate credit account and may not reduce your balance or interest. Do not make an overpayment on a fixed rate without confirming the potential charges and terms with your lender first.
How does it work with a variable rate mortgage?
With a variable rate, you can pay extra without penalty in two ways:
1. Pay a lump sum
You can make a large single payment off the capital part of your mortgage. This will have the effect of either reducing your monthly repayments or shortening the term of the mortgage, but either way you will repay less interest and save money. With this option, it is important that you instruct your mortgage provider to pay the lump sum off the capital part of your mortgage. Before making any overpayment, confirm with your lender that the payment will be applied directly to the mortgage capital.
Note on the examples below
The savings shown depend on your lender’s rules. Not all overpayments are allowed, and limits or charges may apply depending on your mortgage type. The examples below assume that the overpayment is allowed under your mortgage terms and is applied directly to the mortgage capital.
2. Pay more each month than the agreed amount
If you can afford to pay more than your agreed monthly mortgage amount you will repay your mortgage faster and save money by paying less interest. It may be possible to make this type of overpayment by standing order or an online transfer using your internet banking. Talk to your lender to discuss the best overpayment options available to you.

How much can you overpay without penalty?
This depends on your lender and your mortgage type:
- Some lenders allow a set percentage of the balance each year without penalty.
- Others may charge fees for any overpayment on a fixed rate.
Which option saves more: reducing the term or lowering monthly payments?
Keeping your monthly repayments the same after a lump sum payment usually saves more interest and shortens the term faster than reducing your monthly payments.
How do you make an overpayment?
You can usually make overpayments by:
- Standing order
- Online transfer or a lump sum payment
Always confirm the process with your lender.
Do you need to tell your lender how to apply the extra payment?
Yes, for lump sums, instruct your lender to apply the payment to the capital so you reduce the balance and save interest.
Is there a limit on how many times you can overpay?
Policies vary. Some lenders allow unlimited overpayments on variable rates, while fixed rates often have restrictions.
Does paying extra affect your mortgage protection or insurance?
It can. If your mortgage term changes significantly, you may need to update your mortgage protection policy.
Should you pay off higher-interest debts first?
Yes, clearing debts with higher interest rates usually saves more money than overpaying your mortgage.
Is it better to invest spare money instead of overpaying your mortgage?
It depends on your financial goals and the returns you expect. Overpaying your mortgage gives a guaranteed saving on interest, while investments carry risk.
