Fixed Interest Rate

With a fixed rate mortgage, your interest rate and monthly repayments are fixed for a set time as agreed between the lender and borrower. Although a fixed rate means your repayments cannot increase for a set period of time, your repayments will not fall during the fixed rate period. As a result, you could miss out on lower interest rates and lower repayments. Fixed rates may cost more over the long run but they offer peace of mind as you know your repayments will not rise during the fixed rate period.


Loan to Value (LTV) is the amount you can borrow from us relative to the value of the property you're buying. Loan to Income (LTI) is the maximum amount a customer can borrow based on a multiple of their gross income.

This calculator is for illustrative and guidance purposes only and is not an offer of a loan. The limits applied can vary so it’s important to talk to us as early as possible about your plans. The amount you can borrow will depend on your individual circumstances and is subject to lending criteria, terms and conditions. Terms of up to 35 years are available for First Time Buyers, Movers and Switchers to a maximum age of 70. At the end of the LTV Fixed rate term, the LTV Fixed rate rolls on to the corresponding LTV variable interest rate band that applied to the mortgage loan during the Fixed rate period.

The calculation is based on limited information and does not consider your financial circumstances, for example, where you are on an existing fixed rate with your current mortgage provider you may have to pay a breakage fee. Our calculator does not take into account fees that may need to be paid when switching your mortgage, such as legal or valuation fees and does not include the €2,000 switching offer. In addition when you select a fixed rate option and you subsequently drawdown a mortgage on any fixed rate option we may charge you an early breakage fee.

The Higher Value 4 Year Fixed Interest Rate is available to Switchers with a mortgage loan of at least €250,000. Switchers availing of the Higher Value rate can also benefit from the €2,000 Switcher cash offer. Click to find out more about the Higher Value rate Yr means Year.
