The conversation about the future of UK consumer credit tends, in industry settings, to focus on the parts of the market that are already comfortably profitable. Prime borrowers, mainstream personal loans, mortgages priced off institutional funding costs and the segments that mainstream banks compete for with diminishing differentiation. These are perfectly reasonable markets to operate in. They are also markets where the structural growth story is largely behind us, where competition is intense and where customer acquisition costs have risen to levels that compress returns considerably. The more interesting story, for firms thinking commercially about where consumer credit is heading, sits in the segment of the population that mainstream lenders systematically underserve.
The scale of this underserved market is larger than is generally acknowledged. Estimates of the UK adult population without access to mainstream credit, whether through thin files, impaired histories, irregular income or simply being outside the demographic comfort zone of incumbent lenders, run into the millions. These customers do not stop having credit needs because mainstream lenders decline them. They satisfy those needs through more expensive alternatives, through informal channels or through deferring consumption that would otherwise contribute to economic activity. The market exists. The question is who serves it, on what terms and to what standards.
Why mainstream lenders cede the ground
The traditional reasons mainstream UK lenders avoid the subprime segment are partly historical and partly structural. Historically, the segment was associated with payday lending and the doorstep credit market, both of which had reputational and regulatory characteristics that mainstream firms preferred to keep at arm’s length. The Wonga-era crackdown that arrived in the mid-2010s was a corrective necessary for the worst of those practices, but it also left mainstream lenders even more reluctant to participate in any part of the credit market that touched non-prime customers. The result was a vacuum into which a generation of specialist lenders has begun to step.
Structurally, the issue is that mainstream lenders are configured, operationally and culturally, around prime customers. Their decisioning engines, their funding models, their customer service infrastructure and their risk appetites are calibrated for borrowers who present low loss-given-default characteristics and predictable cash flows. Serving non-prime customers requires meaningfully different underwriting, different pricing, different collections capability and different cultural orientation. For a mainstream lender to enter the space credibly would require building or acquiring a parallel operation. Most have chosen not to, which leaves the field open for firms that have built for the segment from the start.
What makes the segment serveable now
Two developments have changed the economics of non-prime lending in ways that make the segment genuinely attractive to operators willing to do the work. The first is Open Banking, which gives lenders direct visibility into how a customer manages money in real time, rather than depending solely on credit reference data that can be both stale and incomplete for thin-file customers. The richness of this data, properly used, allows for affordability assessment that is considerably more accurate than the traditional approach, particularly for the segments that traditional approaches struggle with most.
The second development is the maturation of machine learning techniques in credit risk modelling. Modern models can extract meaningful predictive signal from combinations of behavioural variables that older approaches could not detect. For the prime market, this incremental improvement matters at the margins. For the non-prime market, where prediction accuracy is the single largest determinant of portfolio economics, it can be transformative. The combination of richer data and better models means firms can lend at price points that work for both the customer and the lender, which is the foundational requirement for the segment being viable.
Lenders such as Evlo, whose proposition focuses on accessible loans for customers with poor credit histories assessed primarily on affordability rather than credit score alone, illustrate the model that is emerging. The economics work because the underwriting works. The underwriting works because the data and the modelling have caught up with the complexity of the segment. None of this is theoretical, and the portfolios being built on these foundations are demonstrating that the segment is not just serveable but, in many respects, attractive.
Why this matters for the wider market
The implications for the broader UK consumer credit market are worth considering. As specialist non-prime lenders grow in scale and credibility, they begin to absorb segments of the market that mainstream lenders had previously regarded as too marginal to address. This puts competitive pressure on the segment immediately above, where mainstream lenders have grown comfortable, and it creates the possibility of consolidation at the specialist end as the firms with the best underwriting and capital advantages outgrow their smaller competitors.
For investors, fund managers and B2B service providers in the space, the takeaway is that the structural growth in UK consumer credit over the next several years is unlikely to come from the parts of the market that have dominated industry attention to date. It is more likely to come from the specialist firms serving customers the mainstream has overlooked, operating with the kind of data, technology and regulatory discipline that makes the segment commercially sustainable for the first time at scale. The subprime opportunity is not what it was a decade ago. It is now, increasingly, where the more interesting work is being done.
