Neither is automatically better: the right option depends on your circumstances, borrowing needs and the terms you qualify for. Credit unions may require membership and can assess applications differently from banks, while banks may offer different loan amounts, terms and application processes. Compare the annual percentage rate, total amount repayable, fees, repayment flexibility and any early repayment conditions rather than looking only at the monthly payment. Rates and lending criteria change, so check the current details with the relevant lender and consider guidance from the Central Bank of Ireland or MABS if affordability is a concern.
