Refinancing a Mortgage in Poland: Complete Guide for 2026

Learn how mortgage refinancing works in Poland, when it pays off, what costs to expect and how to calculate your savings before switching to a new lender.

Refinancing a mortgage in Poland means replacing your current home loan with a new one, usually at a different bank offering better terms. With interest rates having moved significantly in recent years, thousands of Polish borrowers can lower their monthly payments or shorten their loan term simply by switching lenders. This guide explains how the process works, what it costs and when it actually makes financial sense.

What is mortgage refinancing?

Refinancing (in Polish, refinansowanie kredytu hipotecznego) is the process of taking out a new mortgage to pay off your existing one. The new loan typically comes from a different bank that offers a lower margin, a better reference rate, or more favourable conditions. Legally, you fully repay the old loan and the new bank takes over the mortgage registered on your property.

When does refinancing pay off?

Refinancing makes sense when the savings from the new, lower rate exceed the total cost of switching. The key factors are:

  • Rate difference — even a 0.5 to 1 percentage point reduction in the margin can save tens of thousands of zloty over the loan term.
  • Remaining loan period — the more years left, the bigger the benefit, because interest accrues over a longer horizon.
  • Outstanding balance — larger balances generate larger absolute savings.
  • Switching costs — new valuation, court fees for changing the mortgage entry, and possible early-repayment fees at the old bank.

What does refinancing cost in Poland?

Typical one-time costs include: a property valuation (around 400 to 1,000 PLN), the court fee for amending the land and mortgage register (around 200 to 300 PLN), a possible early-repayment fee at the old bank (capped at 3% during the first three years for fixed-rate loans, often zero afterwards), and sometimes a commission at the new bank. Always compare the total of these costs against your projected interest savings.

Worked example

Suppose you have 350,000 PLN remaining on a 20-year mortgage at an interest rate of 7.5%, giving a monthly payment of roughly 2,820 PLN. A new bank offers 6.3% for the same 20-year term, reducing the monthly payment to about 2,565 PLN.

  • Monthly saving: about 255 PLN
  • Total saving over 20 years: about 61,000 PLN
  • One-time switching costs: about 1,500 PLN

Even after switching costs, the net benefit is well over 59,000 PLN. The break-even point arrives after roughly six months, so the move clearly pays off.

Step-by-step process

First, gather your current loan agreement and repayment schedule. Second, request offers from several banks and compare the APR (RRSO), not just the nominal rate. Third, apply at the chosen bank, which will order a valuation and assess your creditworthiness. Fourth, sign the new agreement, repay the old loan, and register the mortgage change in court. The whole process usually takes four to eight weeks.

Frequently asked questions

1. Is refinancing the same as consolidation? No. Refinancing replaces one mortgage with a better one; consolidation merges several debts into a single loan.

2. Can I refinance with the same bank? Yes, this is called renegotiation (renegocjacja). It is faster, but banks often offer better deals to new customers.

3. Will I pay an early-repayment fee? For fixed-rate loans, banks may charge up to 3% during the first three years. Variable-rate loans are usually free to repay early after the initial period.

4. Do I need a new property valuation? Usually yes, because the new bank needs to confirm the collateral value.

5. How long does refinancing take? Typically four to eight weeks from application to disbursement.

6. Does refinancing hurt my credit score? A credit inquiry causes a small, temporary dip, but on-time payments quickly restore it.

7. Can I refinance if my property value dropped? It is harder, because a higher loan-to-value ratio may disqualify you or raise the margin.

8. Should I shorten the term or lower the payment? Shortening the term saves more interest; lowering the payment improves monthly cash flow. Choose based on your goals.

9. Are there tax implications? For a primary residence in Poland there are generally no income-tax consequences from refinancing.

10. What documents do I need? Proof of income, the current loan agreement, the repayment schedule, and property documents.
