UK startups are increasingly turning to debt financing in 2025, as tighter equity markets, falling valuations, and stricter investor criteria push founders toward non-dilutive growth, according to new insights from Swoop Funding.
Although the UK economy is showing signs of stabilisation, many early-stage businesses continue to encounter barriers when seeking equity investment. UK equity investment in smaller businesses fell by 2.5% to £10.8 billion in 2024, with year-on-year deal numbers dropping by 15.1% to 2,048, a sign of a more restrained funding environment. Yet average deal sizes (especially in AI) are on the rise, indicating greater selectivity and preference for larger, scalable opportunities.
A recent study also found that small UK businesses now carry double pre-pandemic debt-to-turnover ratios, making access to new finance more challenging than ever amid higher interest rates and depleted reserves.
New insights from business funding platform Swoop Funding reveal that startups across the UK are fuelling growth through debt financing at unprecedented levels in 2025, as a more cautious equity market reshapes the funding landscape.
Why Startups Are Turning to Debt Financing in 2025
The shift toward debt financing is not only about short-term necessity; it reflects deeper changes in the UK funding ecosystem. Founders are weighing the trade-offs more carefully as they navigate an increasingly cautious and selective capital market.
Andrea Reynolds, CEO and founder of Swoop Funding, says, “In 2025, we can see a significant shift in how UK startups are fueling their growth, with a growing reliance on debt financing. This trend is caused by a more cautious equity market. Equity investors have become increasingly selective and valuation-conscious, creating a ‘buyers’ market’ where startups might have to give up more equity for less capital or accept lower valuations.
“In this environment, debt is an attractive alternative, allowing founders to preserve ownership and avoid dilution, which is a non-negotiable for many. We have also seen how the debt market has evolved, with innovative and tailored products, from low-cost startup loans up to £25,000 per director, to more sophisticated instruments designed to solve specific business needs such as VAT funding and invoice finance.”, shares Andrea.
Equity Slowdown Forces Founders to Explore Alternatives
A clear change in investor behaviour is driving this shift. Equity funders remain active but apply stricter criteria when assessing startups.
Reynolds notes, “Equity investors are becoming more selective and valuation-conscious. While there’s still ‘dry powder’ in private equity, investors are looking for strong, high-quality businesses. This ‘buyers’ market’ for equity means startups might have to cede more equity for less capital or accept lower valuations, making debt a more attractive option to preserve ownership.”
Debt Products Evolve to Meet Startup Needs
At the same time, the debt financing landscape is evolving to better serve startup needs, with venture debt, also known as growth credit, becoming more prominent.
“A reliance on debt isn’t necessarily a bad thing – Swoop has long advocated for new businesses to look seriously at startup loans if they are under three years old, as these are a low-cost way to borrow up to £25,000 per company director at a low, fixed interest rate,” Reynolds adds.
“There is also a proliferation of debt products that new businesses will find attractive and tailored to solve particular issues,” she continues.
Diversification of the Lending Landscape
Founders have long complained that traditional bank lending is difficult to access. However, as new players enter the market, alternative finance is stepping in to close the gap, offering non-dilutive options that help businesses retain ownership.
“Businesses have long complained that traditional bank lending is hard to secure – and it’s only getting more difficult. Debt is, however, non-dilutive, which means you’re not giving up a percentage of your business to an investor. The diversification of the lending landscape has been crucial in ensuring that debt remains a viable option for SMEs,” says Reynolds.
Prioritising Capital Efficiency Over Dilution
The shift toward venture debt and alternative lenders reflects a broader shift in startup mindsets. Rather than chasing rapid expansion at all costs, many founders are embracing more disciplined, sustainable approaches to growth.
Reynolds notes, “Given the macroeconomic uncertainty in 2025, there is a clear trend towards more conservative capital deployment strategies among startups… the current environment rewards substance over spin and discipline over bravado, signalling a greater emphasis on reaching break-even and sustainable unit economics earlier, rather than solely prioritising hyper-growth.”
Tips for Funding Success
Andrea Reynolds shares her advice for startups navigating the funding landscape.
Know how much you need and what it will do for you
“Before you even think about approaching a lender or investor, get forensic about your funding needs. Be precise. Don’t pull a number out of thin air. Break down exactly what the money is for (new equipment, marketing campaign, hiring, R&D) and how each pound will contribute to growth. Lenders dislike vague requests.”
Master Your Financial Story and Keep it Tidy
“Your financial records are your business’s autobiography. Make sure it’s a compelling read. Keep immaculate books. Outdated financials are a major red flag. In these days of accounting software, there is no reason why your books can’t be reconciled monthly, not annually. A focus here is a win for your business that goes beyond giving confidence to lenders.”
Look Beyond Your Bank
“Too many entrepreneurs default to their traditional bank for funding, often to be met with disappointment. The UK’s funding landscape is incredibly diverse. Research alternatives; there are specific financial problems built to address specific challenges your business might have.
For example, invoice finance gives you access to cash tied up in unpaid invoices; asset finance is often the best deal for equipment purchases; VAT funding can help you smooth big quarterly bills into easier-to-manage monthly payments.
“Business grants from Innovate UK, local councils, or industry bodies can provide capital without giving up equity. They are competitive but often worth the effort, particularly for innovative or sustainable businesses.”
Use a platform that matches you to the right lenders
“Navigating funding options can be overwhelming, but you don’t have to do it alone. Speaking to an independent advisor or researching funding platforms can help you find the right fit faster and avoid wasting time on applications that aren’t suited to your business.”
