Possibly. The key point is that a fixed rate does not automatically mean you can make unlimited extra payments. Your lender and mortgage terms determine what is allowed during the fixed period.
Why fixed-rate mortgages are different
With a fixed-rate mortgage, the interest rate is agreed for a set period. Because the lender is committing to that rate, the mortgage contract can include restrictions on extra repayments during the fixed period.
That can mean you are allowed to overpay up to a certain amount, while a larger overpayment or early repayment may result in a charge. The exact rule is lender- and product-specific, so do not assume that another borrower's allowance applies to you.
Can I make a monthly overpayment?
Sometimes. Some fixed-rate products allow regular overpayments within a specified limit. Others may restrict them or apply a charge if you go beyond the permitted amount.
Before setting up a standing order or increasing your monthly payment, ask your lender how much you can pay above the contractual repayment during your current fixed period. Also ask whether the allowance resets annually and whether unused allowance can be carried forward.
Can I make a lump-sum overpayment?
A lump sum can reduce your mortgage balance immediately if your lender accepts it and applies it to capital. However, on a fixed rate, the amount you can repay without a charge may be limited.
- How much can I overpay without a charge?
- Is the allowance based on the original balance or the current balance?
- Does the allowance apply per year, per payment or over the whole fixed period?
- Will the payment reduce the capital immediately?
- Will it shorten the term or change the monthly repayment?
- Is there an early repayment charge for the amount above the permitted limit?
What happens if you overpay within the allowed limit?
If an extra payment is applied to capital, your outstanding balance falls. That generally means less interest is charged over the remaining life of the mortgage, assuming the rate and repayment structure otherwise stay comparable.
Whether your monthly repayment changes is a separate question. Some lenders may keep the scheduled repayment and allow the mortgage to finish sooner; others may recalculate repayments. Ask your lender how it will treat an overpayment before deciding how much to pay.
What if there is a charge?
A charge can change the calculation. An overpayment saves future mortgage interest, but you should compare that saving with any fee or early repayment charge before proceeding.
If the amount you want to pay is large, ask your lender for the current overpayment allowance and any applicable charge in writing. Your mortgage statement or fixed-rate terms may also explain the relevant conditions.
Fixed rate vs variable rate overpayments
Variable-rate mortgages are often more flexible about additional repayments, but the actual rules still depend on the lender and product. Fixed-rate mortgages need more care because the fixed-rate contract may include limits or charges.
If you are considering a large payment, compare the options rather than assuming that paying the maximum possible amount is automatically best. You may want to keep an emergency cash buffer or clear more expensive debt first.
Example: a €10,000 lump sum
Imagine you have €10,000 available and want to put it against your mortgage. If your lender confirms that the full €10,000 can be overpaid without a charge and it is applied to capital, the mortgage balance falls by €10,000. Future interest is then calculated on a lower balance.
If the lender only permits a smaller fee-free overpayment during your fixed period, you should compare the interest saving from the permitted amount with the cost of exceeding the limit. The best choice depends on your rate, remaining term, lender rules and alternative uses for the cash.

FAQ
Can you overpay a fixed-rate mortgage in Ireland?
Possibly. Check the terms of your specific mortgage and ask your lender about the fee-free allowance and any charge for paying more.
Can I overpay 10% of my mortgage?
Do not assume that a 10% allowance applies to every mortgage. The permitted amount varies by lender and product. Confirm your allowance directly with your lender.
Can I pay off a fixed-rate mortgage early?
You may be able to, but ending a fixed-rate mortgage early can involve an early repayment charge. Ask the lender for the current charge before making a large payment.
Is it better to overpay or save?
It depends on the mortgage rate, savings return after tax, access to your cash, other debts and your need for an emergency fund. Compare the numbers rather than assuming one option is always better.
