Headline of the quarter: UK startups raised roughly €12bn in Q3 2026, up 24.6% on the same quarter last year, according to Tech.eu's funding tracker. Get the champagne out.

‍

Hold the champagne. Look at what's underneath. The number of funding rounds was 191, down 10.7%. Debt made up €7.4bn of the total, or 62.6%. And the ten largest rounds accounted for 74.5% of disclosed capital.

‍

Here's the part that matters if you're not building an AI infrastructure giant. Three of the largest debt rounds on the list belong to one company, Nscale, at roughly €2.95bn, €2.59bn and €0.79bn. Those three alone add up to about €6.3bn. That's our arithmetic on the published figures, but it suggests something like 85% of that debt total is one name.

‍

So 'most UK startup funding is now debt' is true on paper and misleading in practice. The bigger point is the one underneath: for a lot of founders, the realistic next pound of funding isn't a priced equity round. It's a loan, a facility or a government-backed product. And lenders read your numbers very differently from VCs.

‍

A lender doesn't care about your vision

‍

An equity investor is buying upside. They'll forgive messy numbers if the story is big enough. A lender has no upside. They want to know three things: can you service the debt, what happens if you can't, and how fast would they find out?

‍

That means they care about things many early-stage finance functions treat as an afterthought. Accurate monthly management accounts. A cash flow forecast that ties to the P&L and balance sheet. A clear view of existing commitments, including that HMRC payment plan, the director loan and the lease. And a track record of hitting forecasts, because a covenant is just a forecast with a penalty attached.

‍

The government-backed route

‍

It isn't only big-ticket lending. The British Business Bank lists the Growth Guarantee Scheme, the successor to the Recovery Loan Scheme, as open for applications through accredited lenders since 1 July 2024. It also says Start Up Loans has supported over 125,000 business ideas with more than £1.25bn in lending. Scheme terms and eligibility vary by lender and change over time, so check the current rules before you plan around any of it.

‍

What doesn't change is that the lender, not the scheme, decides. Government backing reduces their risk. It doesn't reduce their paperwork.

‍

Debt isn't free money either. Unlike equity, it comes back on a schedule, whether or not your quarter went to plan. Every monthly repayment is cash you can't spend on hiring or growth, so the runway calculation changes the moment a facility lands. Model the repayments, the interest, and any fees into your cash flow before you sign, not afterwards. A facility that looks like six extra months of runway can turn out to be three once you've accounted for what it costs to carry.

‍

There's also a sequencing question. Some founders use debt to stretch an equity round and reach a stronger milestone before raising again. Others use it as a bridge to nowhere. The difference is almost always whether the plan was modelled properly in advance.

‍

Make yourself an easy yes

‍

Debt rewards boring. If you're considering a facility in the next twelve months, there are four jobs worth doing now.

‍

Close your books quickly. Lenders want recent numbers. If your last closed month is eight weeks old, that's the first conversation you don't want.

‍

Build the forecast lenders will test. Base case and a downside, with the maths on repayments visible. If the downside breaks your ability to repay, better you know first.

‍

Clean up the balance sheet. Unreconciled accounts, stale suppliers, unclear intercompany balances. These are small things that make a lender wonder what else is untidy.

‍

Know your own covenants. The time to understand a covenant is before you sign it, not in month seven when a ratio quietly slips.

‍

This is the unglamorous side of the 'financial model for startup' conversation. The same model you'd show an equity investor needs a lender-shaped view: cash, repayment capacity and headroom. A fractional finance team can build both at once, without the headcount.

‍

Funding headlines make good LinkedIn posts. Lender-ready numbers make good businesses.
