Open banking does not replace a credit check; it complements one. A credit bureau shows borrowing and repayment history and a score across the whole market. Open banking shows real, current money in and out of the accounts a customer connects. They answer different questions, history versus present affordability, and most lenders get the best decision by using both together.
What each one shows
A credit bureau holds a history: the accounts a person has held, how they repaid, defaults, county court judgments, and a score summarising it, drawn from across lenders whether or not the customer tells you about them. It is a market-wide, historical view. Open banking holds the present: the actual salary arriving, the actual rent going out, the real commitments and spending in the accounts the customer connects, close to real time. One tells you how someone has borrowed; the other tells you what they can afford now. See affordability assessment.
Side by side
| Open banking | Credit bureau | |
|---|---|---|
| Shows | Real income and spending now | Borrowing history and a score |
| Recency | Near real-time | Historical, updated periodically |
| Coverage | Only connected accounts | Market-wide, including unshared accounts |
| Needs consent | Yes, the customer connects | A search on the customer's file |
| Best for | Affordability, income, current conduct | History, defaults, cross-market exposure |
When to use both
Each source has a blind spot the other fills. Open banking does not see borrowing held at a lender whose repayments do not pass through a connected account; a bureau does not see day-to-day affordability or very recent change. A thin bureau file (a young or new-to-country applicant) can hide a perfectly affordable customer, whom open banking reveals; a healthy-looking account can sit alongside heavy borrowing elsewhere, which the bureau catches. Using both reduces both wrong declines and avoidable defaults.
Combining them in a decision
The practical pattern is to use the bureau for history and cross-market exposure, and open banking for current income and affordability, then decide on the combined view. This is how Credit Canary works: it brings TransUnion bureau data and open banking into one decision, alongside identity data, so you are not stitching sources together yourself. The result is a single, explainable decision rather than two reports you have to reconcile. See the platform.
From the data consumer's side
The question is rarely "which one?"; it is "how do I use them together?". For a prime applicant with a thick file, the bureau may be enough; for thin-file, self-employed or borderline cases, open banking is what turns a decline into a confident yes, or a risky yes into a justified no. Build your policy to call on each where it is strongest, and keep the combined decision auditable, which matters under the Consumer Duty.
How Credit Canary does it
Credit Canary combines open banking with TransUnion credit bureau data and identity data in one platform, so origination, affordability and decisioning run on a single, current view. You get history and present affordability in one decision, not two disconnected checks.
Common questions
Does open banking replace a credit check?
No. Open banking shows real money in and out of the accounts a customer connects; a credit bureau shows borrowing history and a score across the market. They answer different questions, and most lenders use both rather than choosing one.
What does a credit bureau show that open banking does not?
Borrowing and repayment history across lenders, defaults, county court judgments and a score, including accounts the customer has not connected. Open banking does not see borrowing held elsewhere unless its repayments pass through a connected account.
What does open banking show that a credit bureau does not?
Current, real spending and income: actual salary, actual rent, actual commitments, close to real time. A bureau file is historical and does not show day-to-day affordability.
Should lenders use open banking or a credit bureau?
Usually both. The bureau gives history and a market-wide view; open banking gives current affordability. Combined, they give a fuller and fairer decision than either alone.
