How Open Banking Could Unlock Credit for the UK's Most Overlooked Borrowers

How Open Banking Could Unlock Credit for the UK's Most Overlooked Borrowers

A growing segment of UK consumers sits in a frustrating financial no-man's land: not technically insolvent, but effectively invisible to mainstream lenders. These so-called "credit invisibles" — people whose credit files are thin, patchy, or scarred by a single period of hardship — are routinely declined for loans, credit cards, and other everyday financial products, not because they cannot afford to repay, but because traditional credit scoring systems lack the data to assess them fairly.

Salad Finance, a Community Development Finance Institution (CDFI) that lends primarily to NHS and public sector workers, has positioned itself at the intersection of community finance and open banking technology as one potential answer to that problem. The lender recently secured an Account Information Service Provider (AISP) registration from the Financial Conduct Authority, allowing it to access transaction data directly from applicants' bank accounts — with consent — as part of its affordability and creditworthiness assessments.

Why Traditional Scoring Falls Short

The structural problem with conventional credit scoring is well understood within the industry, even if it remains stubbornly persistent in practice. Bureau-based models are backward-looking by design: they reward a long, clean credit history and penalise absence of data as much as negative data. That creates a compounding disadvantage for people who have recently migrated to the UK, have only ever used cash or debit, have recovered from a brief period of financial difficulty, or have simply never needed to borrow before.

For this population, a missed payment from years ago — or no payment history at all — can be as disqualifying as chronic debt. The result is that lenders optimised for risk avoidance push these borrowers toward high-cost credit alternatives, which in turn creates the very repayment stress the original lender sought to avoid.

Community finance models, by design, are oriented toward borrowers that mainstream institutions treat as unprofitable edge cases — and that distinction matters when it comes to how creditworthiness is actually evaluated.

Open Banking as an Affordability Lens

Salad's AISP registration is significant in operational terms: it means the lender can now directly ingest a consenting applicant's transaction history rather than relying on bureau data alone. In principle, real-time bank account data offers a more granular picture of financial behaviour — regular income deposits, stable outgoings, the absence of persistent overdraft use — that a credit file may not capture at all for thin-file borrowers.

This approach aligns with a broader direction of travel in UK lending. Open Banking Limited has documented multiple case studies in which lenders using transaction data have been able to extend credit to applicants who would have been declined under bureau-only assessments, or to price risk more accurately for near-prime borrowers. The FCA's Consumer Duty framework, which came into full force in 2023, has also increased regulatory pressure on lenders to demonstrate that their affordability assessments reflect a borrower's actual financial position — a requirement that open banking data is well-suited to support.

Whether Salad's specific implementation delivers materially better outcomes for credit-invisible borrowers remains to be demonstrated at scale. The quality of any open banking-based credit model depends heavily on the sophistication of the underlying analysis and the breadth of data it can interpret — factors that vary considerably across lenders.

Community Finance's Structural Advantage

What distinguishes CDFIs from technology-first lenders making similar claims about alternative data is the institutional orientation. CDFIs operate under an explicit social mission and are regulated accordingly; their lending mandates are structured around serving underserved communities rather than maximising risk-adjusted returns for shareholders. That means credit decisions can, at least in principle, incorporate a more holistic assessment of a borrower's circumstances.

Salad's focus on public sector workers — a population with stable employment but often modest wages — gives it a relatively well-defined borrower profile from which to build and validate alternative scoring models. That specificity is an asset: the more homogeneous the target population, the easier it is to identify reliable behavioural signals in transaction data.

What Remains to Be Proven

The broader question for the sector is whether community finance and open banking technology together can shift the needle on financial inclusion at meaningful scale, or whether these solutions remain valuable but niche. CDFIs by definition operate with constrained capital relative to mainstream banks. Salad raised £4.3 million from retail investors — confirmed by multiple sources — a figure that underscores both the genuine community appetite for mission-aligned finance and the capital intensity challenge that limits how many borrowers any single CDFI can ultimately serve.

The technology case for open banking in credit assessment is increasingly well-made. The harder problem — deploying it at the scale required to meaningfully reduce financial exclusion — is still very much a work in progress.
