Venture debt gone wrong: what happens when a UK scaleup can't repay
Venture debt looks like cheap, non-dilutive growth capital until a scaleup misses a covenant or a repayment, and then its position as secured debt changes everything.
Why the downside case matters
Most explainers on venture debt focus on why founders like it: it extends runway without diluting the cap table the way another equity round would. That’s true, but it’s only half the picture. Venture debt is still debt. It sits above ordinary shareholders in the pecking order, it usually comes with security over company assets, and it comes with covenants that bite if performance slips. Understanding what happens when things go wrong is arguably more useful to a founder than understanding the upside case, because the downside is where control can be lost fastest.
Security and priority, in plain terms
Venture debt lenders in the UK typically take a debenture, a form of security registered at Companies House that gives them a fixed and floating charge over the company’s assets. In practice this means that if the company becomes insolvent, the venture debt lender is repaid before unsecured creditors and long before ordinary shareholders see anything. Equity investors, including the VCs who backed the priced rounds, rank behind the debt. Founders sometimes underestimate this because venture debt is pitched alongside equity as ‘growth capital’, but in an insolvency it behaves exactly like what it is: a senior secured claim.
Covenants: the early warning system
Venture debt agreements almost always include covenants, conditions the borrower must keep meeting for the loan to stay in good standing. Common ones include minimum cash balances, revenue or growth thresholds, and restrictions on further borrowing or major asset disposals. Covenants are not the same as the repayment schedule. A company can be current on every interest and principal payment and still be in breach simply because cash fell below an agreed floor, or growth slowed below a target set when the deal was signed.
A covenant breach does not automatically mean default in the sense of demanding immediate repayment, but it does give the lender contractual rights: to charge a higher interest margin, to demand more frequent reporting, to restrict further spending, or in more serious cases to accelerate the loan and demand repayment in full. Lenders rarely want to push a portfolio company into insolvency, since recovering a loan from a distressed early-stage business is messy and expensive, but the leverage a covenant breach hands them is real and immediate.
What lenders actually do when a breach happens
In practice, most covenant breaches are resolved through negotiation rather than enforcement. The lender and the company usually agree a waiver, sometimes for a fee, or renegotiate the terms: a reset covenant level, a fresh equity injection required as a condition, board observer or information rights extended, or warrant coverage increased. This is where the interaction with equity investors becomes critical. Existing shareholders are often asked to put in a rescue round or bridge specifically to cure the breach and keep the lender comfortable, which means a venture debt problem can quickly turn into a dilutive equity event anyway, sometimes on worse terms than if the company had simply raised more equity earlier.
Cash sweeps and step-in rights
Some venture debt facilities include a cash sweep mechanism, meaning that if certain trigger events occur, a portion of incoming cash is automatically directed to repaying the loan rather than being available for operations. Others give the lender the right to appoint an observer to the board, or in extreme cases, step-in rights that let the lender take more direct control of company decisions. These provisions are usually dormant until triggered, which is exactly why founders need to read them carefully at signing rather than assuming they will never apply.
Personal exposure and director duties
Venture debt is a company liability, not a personal guarantee, in the vast majority of UK scaleup deals, so founders are not usually personally on the hook for repayment. However, UK company law imposes duties on directors that sharpen once a company is in financial difficulty. If a business becomes insolvent or is likely to, directors must start considering the interests of creditors, including the venture debt lender, ahead of shareholders. Continuing to trade while insolvent, known as wrongful trading, can expose directors to personal liability regardless of what the loan documents say. This is a good reason to take early, proper advice the moment covenant headroom looks tight, rather than waiting for a formal breach notice.
The practical takeaway for founders
Venture debt works best as a bridge to a clearly foreseeable milestone, not as a substitute for a healthy equity runway. Before taking it on, founders should model a downside scenario: what happens to covenant compliance if growth is twenty or thirty per cent below plan, and what the lender’s realistic response would be. Boards should also understand where the debt sits relative to any existing equity investment agreements, since some venture rounds include consent rights over new borrowing. Speaking to an insolvency-experienced adviser before signing, not after a breach, is the difference between a manageable renegotiation and a forced sale of the business.
