BIK: how to check and improve your credit history
Before a bank looks at your income, it looks at your BIK report. That report decides whether your application gets analysed at all. We show you how to read it, what damages it and why the line "I don't have any loans, so my record is clean" is false.
What BIK is and what it knows about you
Biuro Informacji Kredytowej (BIK) is Poland's credit bureau: it collects data on the credit commitments of people in Poland. It is not a "blacklist" - that is a common and harmful shortcut. BIK collects data on every commitment: the unpaid one, the one being repaid perfectly and the one repaid on time ten years ago.
BIK receives information about:
- bank loans - cash loans, mortgages, car loans,
- credit cards and overdraft limits,
- instalment purchases - including the "0%" ones at an electronics shop,
- loans from non-bank lenders, i.e. payday loans,
- guarantees you have given for someone else,
- credit enquiries - the fact that a lender has checked you.
BIK collects data on credit commitments (banks, credit unions known as SKOKs, loan companies). BIGs (economic information bureaus) - such as KRD, ERIF or BIG InfoMonitor - collect data on other debts: an unpaid phone contract, rent, a fine, an electricity bill.
When you apply for a loan, the bank checks both. If you are sorting out your situation, check both databases - fixing only one of them is not enough.
How to check BIK: two routes, one of them free
Everything happens on bik.pl. You create an account, confirm your identity (with a PLN 1 verification transfer, through online banking or with an electronic ID card) and you get access to your data. Then the two paths split.
| BIK Report (paid) | Copy of your data under GDPR (free) | |
|---|---|---|
| Cost | approx. PLN 50, one-off | PLN 0 |
| How often | unlimited | once every 6 months |
| List of commitments | yes | yes |
| Month-by-month repayment history | yes | yes |
| Credit enquiries | yes | yes |
| Credit score | yes | usually not |
| Waiting time | instant | up to 30 days |
The free route is based on Art. 15 GDPR (RODO in Polish), which gives everyone the right to access their data and to a free copy. BIK honours this right by providing a document once every six months. It contains complete information about your commitments and about who has checked you. What it usually does not contain is one thing: the score - because that is an analytical product of BIK, not data that BIK holds about you.
Always before applying for a mortgage, and at least three months in advance. The reason is practical: if you find an error in the report, correcting it takes weeks. Discovering it on the day you apply means it is already too late.
For a routine check every six months, the free copy of your data is perfectly sufficient.
What is in the report: score, history, enquiries
The score: from 192 to 631 points
The BIK score is a number in the range 192-631 points, also shown as stars (from one to five). It answers one question: how likely is it that this person will repay a new commitment on time. The higher, the better.
| Points | Rating | What it means in practice |
|---|---|---|
| 192-279 | very low | a mortgage is practically out of reach |
| 280-345 | low | possible refusal or much worse terms |
| 346-436 | average | a loan is realistic, but without preferential margins |
| 437-509 | good | the bank is keen to talk |
| 510-631 | very good | the best terms the bank has on offer |
A fair caveat: the BIK score is not the bank's decision. Every bank has its own scoring model, in which BIK is one important but not the only input. Alongside it are your income, your type of employment and the result of the borrowing capacity calculation. The BIK score decides more whether you talk at all than how much you get.
Repayment history: 60 months under the microscope
For each commitment the report shows month by month whether the payment arrived on time. Delays are grouped: up to 30 days, 30-60 days, 60-90 days, over 90 days. This is exactly where a credit analyst looks - and they look for a pattern, not a single incident.
One payment four days late three years ago usually means nothing. Six payments a couple of weeks late in the last year paint a picture of someone who is not in control of their budget - and that is how it will be read, even if there was a good reason every time.
Credit enquiries: who checked you and when
Every time you apply for credit, the lender asks BIK for your data, and that enquiry is recorded and visible to other banks. Enquiries from the last 12 months affect your score.
Scoring models recognise the "customer comparing offers" pattern and treat a series of enquiries in a short window (a few days to a couple of weeks) far more leniently than enquiries spread evenly over six months. The latter looks like desperately hunting for money after one refusal after another - and that is exactly how it will be assessed.
In practice: get all your documents together, pick 3-5 banks and apply within one week. Not "one in January, one in March, one in May".
An important distinction: checking your own report on bik.pl is NOT a credit enquiry and has no effect on your score whatsoever. You can do it without worrying.
The myth that costs the most: "no history in BIK is a good thing"
This belief is widespread in Poland and it is wrong. It sounds logical: since BIK collects data about loans, if I have no loans, I am "clean". The problem is that a bank is not looking for cleanliness. A bank is looking for evidence.
An empty BIK report does not tell the analyst "this person is reliable". It says "we know nothing about this person". And a financial institution that does not know assumes risk by default - because that is how any statistical model behaves when it has no input data.
BIK report: empty
You have never had a loan, a card or an instalment plan. The bank has no grounds at all to believe you will pay back PLN 400,000. Often the score is not calculated at all or comes out low.
BIK report: 2 years without a slip
A laptop bought in instalments, repaid to the day. A credit card with a PLN 5,000 limit, 15% used and paid off in full. Twenty-four green boxes in the repayment history.
You don't need debt for this. You need documented repayments.
1. Equipment on 0% instalments. A phone or a washing machine spread over 10 instalments at the shop. You pay the same as with cash, and you leave a full record of on-time payments in BIK.
2. A credit card used sensibly. A low limit, payments for fuel and shopping, paying off the full balance before the end of the interest-free period. Cost: zero in interest. Result: a year or more of clean history.
3. Time. A history builds up over months. If you are planning a mortgage in two years, start now, not a month before you apply.
And the key point: this works only if you repay flawlessly. A history built in a hurry and then damaged is worse than none at all.
What damages your score
Late payments
The heaviest hitter. Just 30 days overdue is an entry that every subsequent bank sees. Above 60 days a rule kicks in that allows your data to be processed without your consent - more on that shortly.
If you know you won't make a payment this month - call the bank before the due date. A payment holiday, a suspended instalment or an amendment to the agreement cost far less than a late-payment entry that will stay with you for years.
Using more than 70-80% of your card limit
This one surprises people the most. A card with a PLN 10,000 limit on which you constantly carry PLN 8,500 of debt, paying every month without delay, lowers your score. The model reads high limit usage as cash-flow strain: if someone is always living at the edge of their limit, they probably have no financial cushion.
A healthy level is below 30% of the limit. It is just a change of habit, not a change in your finances - and it shows in your score.
Careful, because these are two different mechanisms: using the limit damages your score, while the granted limit itself - even untouched - lowers your borrowing capacity. The bank usually counts 3-5% of the limit as a monthly commitment:
| Situation (net income PLN 8,000, 25-year mortgage, 7.5%) | Maximum monthly payment | Borrowing capacity |
|---|---|---|
| No credit card | PLN 4,000.00 | PLN 440,188.92 |
| Card with a PLN 20,000 limit, untouched | PLN 3,400.00 | PLN 374,160.58 |
| Difference | PLN 600.00 | PLN 66,028.34 |
PLN 66,028.34 of borrowing capacity for a card you have not used even once. If you are getting ready for a mortgage and the card is sitting in a drawer - close it and get a confirmation of closure from the bank. Numbers calculated with our borrowing capacity calculator.
Many credit enquiries in a short time
We covered this above. In short: a series of applications within one week is fine, applications spread evenly over six months look like a chain of refusals.
Payday loans - even ones repaid to the day
This is the most underestimated item on this list.
A credit analyst does not see a payday loan as "a commitment repaid on time". They see it as proof that at some point your budget was short of PLN 1,000 for a month - and that you then reached for a product with an APR of over 300%.
In the lending policy of many banks a payday loan is a red flag regardless of whether you repaid it perfectly. Some lenders reject a mortgage application automatically if a non-bank loan appeared in the last 12-24 months. The data stays in BIK for 5 years.
That is the real price of a payday loan - incomparably higher than the fee in the agreement. We break it down in the article "Payday loans: why an APR of 1000% is not a typo".
What improves your score
The good news: the list is short, boring and entirely within your control.
| Action | How quickly you see the effect | Strength of impact |
|---|---|---|
| Paying on time, every instalment to the day | 1-3 months | very strong |
| Bringing card usage below 30% of the limit | 1-2 months | strong |
| Closing unused limits and cards | 1-2 months | moderate (but strong for borrowing capacity) |
| No new credit enquiries | 3-12 months | moderate |
| A long, unbroken history without arrears | years | very strong |
Note the last row. It cannot be sped up. There is no service, course or company that will "clean your BIK" or "raise your score in a week". If someone promises you that for a fee - they are selling you something they don't have. The only thing that really works is time plus on-time repayments.
How long "cleaning BIK" takes. Specific time limits
The name is misleading, because nothing gets "cleaned" - the data simply expires. The rules are set by law, not at anyone's discretion.
| Type of data | How long it stays in BIK | Is your consent needed |
|---|---|---|
| Active commitment (being repaid) | for the whole repayment period | no |
| Commitment repaid on time | up to 5 years | yes - you decide |
| Arrears over 60 days | up to 5 years | NO - consent is not needed |
| Credit enquiries | visible for approx. 12 months | no |
And this is where a decision comes in that few people know they have.
Once a loan is repaid, you have the right to withdraw your consent to the processing of data about it. Many people do this by reflex, believing it "cleans BIK".
It is usually shooting yourself in the foot. By withdrawing consent, you remove from the report the proof that you repaid the loan perfectly - the most valuable thing you have there. What remains is an empty report and the "unknown risk" from the previous section.
Withdrawing consent really only makes sense if your repayment history was bad - and not always even then, because with arrears of more than 60 days the bank can process the data without your consent for 5 years anyway. You withdraw consent and the entry stays. Before you do anything - download the report and check exactly what you are removing.
How to correct an error in BIK: three steps
Errors happen: a payment made on time but booked late, a loan repaid but still shown as active, a commitment belonging to someone with the same name. The procedure is fixed and it is worth knowing it in the right order, because getting the order wrong costs weeks.
Step 1: a complaint to the bank or company that supplied the data
This is the most important step and the one most often skipped. BIK is only a database - it cannot change data on its own that it received from a bank. Only the institution that supplied it can correct it.
You file a complaint with the bank (in writing or through online banking), describe the error and attach evidence: a transfer confirmation, a certificate of full repayment, correspondence. The bank has 30 days to reply (up to 60 in particularly complex cases).
Step 2: an application to BIK
Once the bank accepts the complaint, it should pass the correction to BIK itself. If it does not, or drags its feet, you apply directly to BIK (through your account on bik.pl or by post), attaching the bank's reply accepting the complaint. BIK then asks the institution to verify the data.
You can also request that a note about the ongoing clarification procedure be added to the disputed entry - banks that check you in the meantime will see it.
Step 3: UODO or the Financial Ombudsman
If the bank rejects the complaint and you have hard evidence:
- A complaint to the President of UODO (the Polish data protection authority) - data in BIK is personal data, and you have the right to have it corrected (Art. 16 GDPR). The procedure is free of charge.
- An application to the Financial Ombudsman (Rzecznik Finansowy) - if the dispute concerns the way the bank has treated you as a customer. Also free.
- Your local consumer ombudsman (miejski rzecznik konsumentów) - free legal help and support in handling the case.
Everything in writing, everything dated, everything with proof of delivery. A phone call to the helpline after which "the man promised he would fix it" does not exist in any procedure. A request filed in online banking with a case number - does.
Three things to remember
1. An empty BIK report is not a clean slate. It is a blank page. The bank has nothing to judge you by, so it assumes risk. A short but flawless history beats no history.
2. Check your report three months before you apply. The free GDPR copy of your data every 6 months is enough for a routine check; before a mortgage it is worth paying PLN 50 for the full report with the score. Correcting an error takes weeks - you need time for it.
3. A payday loan costs more than the agreement shows. It stays in BIK for 5 years and can block a mortgage, even if you repaid it to the day.
Do the maths yourself
Borrowing capacity calculator
A good BIK history opens the door, but borrowing capacity decides the amount. Enter your income, living costs, existing repayments and - crucially - your card limits. You will see how much capacity a card you don't even use takes away from you. All the numbers in this article were calculated by the same engine.

The borrowing capacity figures were calculated with the
js/finance.js engine (the creditworthiness() function) for a net income of
PLN 8,000, living costs of PLN 2,500, a 25-year loan at an
interest rate of 7.5% with a 2.5 pp buffer and a DSTI ratio of 50%; the burden
of the card limit was taken as 3% of the limit per month. The BIK score bands
are indicative - BIK does not publish a fixed map of ranges, and each bank
interprets the result according to its own policy. The data retention periods are described
in line with the Polish Banking Law and the Consumer Credit Act; in a specific case,
