Non-Bank SME Lending in the UK: Strategic Leadership and Tech-Driven Innovation Reshape the Landscape

The UK's small and medium-sized enterprise (SME) lending sector is undergoing a seismic shift. Traditional banks, once dominant, now account for less than 40% of SME lending, while challenger banks, fintechs, and specialist lenders have surged to 60% of the market. This transformation, fueled by technological innovation and a growing demand for flexible financing, has created fertile ground for companies like Momenta Finance. The appointment of Tim Boag as CEO in September 2025 marks a pivotal moment for the firm, positioning it to outperform traditional lenders and alternative peers by accelerating digital transformation, expanding product offerings, and targeting underserved SME markets.

The Rise of Non-Bank Lenders: A Structural Shift

The UK's SME finance ecosystem has long been constrained by the rigid lending practices of traditional banks. Post-2008, these institutions adopted a risk-averse approach, prioritizing property-backed loans and neglecting the needs of service-oriented SMEs. This created a £90 billion funding gap, which alternative lenders swiftly filled. By 2025, challenger banks and fintechs now dominate 60% of SME lending, driven by their agility, digital-first models, and tailored solutions. For example, fintechs like Iwoca offer unsecured loans of up to £500,000 within hours, while asset-based lenders such as Capify provide financing against invoices or equipment.

The government's Growth Guarantee Scheme has further catalyzed this shift, with SME lending to the smallest businesses rising 30% year-on-year in Q1 2025. Yet, despite this growth, net lending remains negative, as repayments outpace new borrowing. This highlights a critical opportunity: SMEs are seeking not just access to capital but flexibility and speed—areas where non-bank lenders excel.

Momenta Finance's Strategic Rebuild: Tim Boag's Vision

Momenta Finance's appointment of Tim Boag as CEO is a masterstroke in this evolving landscape. With 35 years of experience at institutions like RBS, NatWest, and Aldermore Bank, Boag brings a rare blend of traditional banking expertise and a challenger's agility. His track record includes scaling commercial lending portfolios and strengthening credit performance, but his focus at Momenta will be on innovation.

Under Boag's leadership, Momenta plans to:
1. Expand Product Offerings: The firm will diversify its suite of SME loans, bridging loans, asset finance, and cash advances, with tailored terms for sectors like logistics, construction, and technology.
2. Leverage Technology: Momenta aims to deepen its use of AI-driven risk assessments, real-time data analytics, and automated underwriting to reduce decision times from days to minutes.
3. Target Underserved Markets: By focusing on SMEs in high-growth but capital-starved industries (e.g., green tech, regional logistics), Momenta can capture a share of the £90 billion funding gap.

Boag's strategy aligns with broader trends: the UK's service-based economy (81% of GDP) demands financing solutions that don't rely on physical collateral. Momenta's digital-first approach—streamlining applications, offering transparent pricing, and providing post-lending support—positions it to outperform peers like Allica Bank or Iwoca, which still rely heavily on unsecured lending.

Competitive Advantages: Technology and Leadership

Momenta's edge lies in its ability to merge traditional banking rigor with fintech agility. While competitors like Iwoca rely on algorithmic lending, Momenta is building a hybrid model: human oversight for high-risk cases, AI for standard applications. This reduces defaults while maintaining speed—a critical differentiator in a sector where 65% of SMEs cite “slow approval times” as a barrier to borrowing.

Moreover, Boag's experience in structured finance and commercial lending allows Momenta to design complex products (e.g., asset-backed securitizations) that many fintechs lack the infrastructure to manage. This could attract larger institutional investors, boosting the firm's capital reserves and enabling faster scaling.

Investment Case: A Fintech with Scalable Potential

For investors, Momenta represents a compelling opportunity in a sector poised for growth. The UK's SME lending market is expected to expand by 8–10% annually through 2027, driven by government incentives and the need for sustainable finance. Momenta's focus on underserved SMEs, coupled with Boag's leadership, positions it to capture a disproportionate share of this growth.

Key metrics to watch:
- Loan Book Growth: Momenta's gross lending to SMEs rose 13% year-on-year in 2024 to £16 billion. Under Boag, this could accelerate as product diversification expands.
- Cost Efficiency: The firm's digital tools are expected to reduce origination costs by 20–30%, improving margins.
- Market Share in Niche Sectors: Targeting high-growth industries like green construction or logistics could yield a 15–20% market share within three years.

Risks and Mitigations

No investment is without risk. Regulatory scrutiny of non-bank lenders remains a concern, particularly as the FCA tightens rules on credit assessments. However, Momenta's hybrid model—combining AI with human underwriters—should mitigate this. Additionally, economic volatility could dampen SME borrowing, but the firm's focus on short-term, flexible loans (e.g., bridging loans with 24-month terms) aligns with cyclical demand.

Conclusion: A Fintech for the Future

The UK's non-bank SME lending sector is no longer a niche market—it's a cornerstone of economic resilience. Momenta Finance, under Tim Boag's leadership, is uniquely positioned to thrive in this environment. By marrying technological innovation with strategic product expansion and a focus on underserved SMEs, the firm is poised to outperform both traditional banks and fintech peers. For investors, this represents a rare opportunity to back a fintech with a clear vision, scalable technology, and a leader who understands both the challenges and opportunities of the post-banking era.
