Open Banking has changed how many UK lenders assess affordability, replacing manually uploaded statements and self-declared figures with secure, direct access to real transaction data — often making the process both faster and more precisely accurate than older methods.
What Open Banking actually is
Open Banking is a UK regulatory framework that allows you to securely share your bank transaction data directly with authorised third parties — including many lenders — through a regulated, consent-based connection, rather than by uploading PDF statements or manually entering figures. It's built on strict security standards regulated by the Financial Conduct Authority (FCA) and requires your explicit, revocable consent each time.
How an Open Banking affordability check works in practice
- During your application, you're asked to securely connect one or more bank accounts via Open Banking, typically by logging into your bank's own secure app or website through the process
- You explicitly consent to share a defined period of transaction data (commonly the last 3 to 12 months) with the lender or their affordability assessment provider
- The data is analysed automatically, often using software that categorises income, regular commitments, and spending patterns
- The lender uses this analysis, alongside other application information, to form a detailed, evidence-based affordability decision
- You can typically revoke access at any time, and the connection is generally read-only, meaning the lender cannot move money or make changes to your account
How it differs from traditional statement checks
| Traditional (uploaded statements) | Open Banking | |
|---|---|---|
| Data source | PDF or printed statements you provide | Direct, secure connection to your bank |
| Speed | Can be slower, manual review | Often faster, largely automated |
| Risk of tampering | Documents can theoretically be altered | Data comes directly from your bank |
| Consent required | Implicit via submission | Explicit, per-connection consent |
Is it safe?
Does it change what's assessed, or just how it's gathered?
Largely the latter — the same broad categories covered elsewhere in our affordability guides (income, existing commitments, essential and discretionary spending, gambling or BNPL activity) are still what's being assessed. Open Banking mainly changes the speed, accuracy and source of the underlying data, rather than introducing entirely new criteria.
Do you have to use Open Banking?
In most cases, lenders offering an Open Banking option also provide a traditional route (uploading statements manually), though Open Banking is often faster and, in some cases, may support a more favourable or efficient assessment simply because the data is clearer and more complete than manually reviewed documents.
Preparing for an Open Banking check
Because the data is pulled directly and completely, there's little room for selective presentation — the same preparation that helps any affordability check (reducing discretionary spending, clearing BNPL balances, avoiding unexplained large transactions) applies just as much, if not more, here, since the full picture is captured automatically.

The bottom line
Open Banking affordability checks use secure, regulated, consent-based access to your real transaction data to assess the same underlying factors as a traditional statement review, generally faster and with less room for manual error. Preparing your genuine spending and income position well ahead of applying remains the best way to get a favourable outcome either way.
