PKO Bank Polski vs mBank

Product: Mortgage

PKO Bank Polski and mBank are the two main players on Poland's mortgage market. PKO BP is the price leader with a floor margin of 1.8% at 30% down; mBank offers the fastest process (4–6 weeks). The pick depends mainly on whether you prioritise the lowest margin or the speed, and on the down payment.

Verdict

PKO BP's margin starts at 1.8% at 30% down, an active current account and life insurance at PKO. Without these terms the margin rises to 2.4–2.7% — comparable to mBank (2.0% with a full product mix, 2.3–2.6% for non-account clients). For a client at 20% down without an account at either bank, mBank usually beats by 0.2–0.3 pp. For a client at 30% down with an active PKO account, PKO BP wins by up to 0.5 pp.

Speed is a sharp differentiator. mBank: 4–6 weeks from complete documents to decision, including 3 weeks for valuation. PKO BP: 6–10 weeks, including 4 weeks for valuation. For a client on a signed pre-contract deadline mBank is a clear win.

Government schemes: PKO BP is the primary operator of the Family Housing Loan and Mieszkanie na Start. mBank runs these programmes at smaller scale. A client qualifying for state subsidies practically always finds better terms at PKO BP than mBank.
