Why the Cheapest Capital Is Often the Most Expensive
For mid-sized UK businesses, funding decisions are rarely about access to capital alone. They are about timing. The headline interest rate may look attractive, but slow capital can quietly erode value, momentum, and strategic options.
Here are the key considerations CFOs should consider when evaluating funding sources.
- Lost deals and broken momentum
Delays in funding don’t just slow growth – they can stop it entirely.
- ACCA guidance suggests that secured or complex bank lending typically takes two to three months to complete, particularly where new security, covenants, or committee approval are required.
- M&A transactions can collapse if funding certainty isn’t achieved within agreed exclusivity windows.
- Operational impacts include:
- Missed seasonal opportunities
- Lost supplier discounts or inventory advantages
- Delayed market entry or product launches
- Operational impacts include:
Momentum is fragile. Once lost, it is expensive – and sometimes impossible – to rebuild.

Enterprise value depends on timing, not just cost of capital
Enterprise value is shaped by when growth happens, not only how cheaply it is funded.
- Valuations are driven by forward earnings, growth visibility, and execution credibility.
A delayed investment can push revenue recognition into a later period, depressing near-term EBITDA and valuation multiples.
- Valuations are driven by forward earnings, growth visibility, and execution credibility.
- For private companies, even a single missed growth cycle can materially impact exit timing and price.
- British Business Bank research shows that a declining proportion of UK firms are accessing external finance, despite ongoing investment needs – highlighting a structural friction, not a lack of viable businesses.
A marginally higher cost of capital is often outweighed by faster revenue realisation and stronger strategic positioning.
Conditional approvals create false security
Many CFOs rely on ‘approved in principle’ facilities – but finance can be derailed by additional lending conditions.
British Business Bank data shows that many businesses either receive less finance than requested or withdraw applications entirely, often due to uncertainty, conditions, or timing risk.
For CFOs, this creates planning risk:
Boards and management teams plan around funding that never fully materialises.
Time is lost pursuing approvals that ultimately fail or arrive too late.
The hidden cost of waiting
Delayed funding carries real, measurable costs:
- Opportunity cost often exceeds interest savings by multiples.
- Management time diverted into repeated lender engagement.
- Increased execution risk as markets, suppliers, or customers move on.
In volatile conditions, certainty and speed frequently matter more than headline pricing. That’s why the UK lending market has shifted to include new, alternative routes to finance. Indeed, challenger and specialist banks now account for around 60% of gross SME lending, reflecting demand for faster, more flexible capital.
This is not about weaker credits – it reflects the need to match capital to real business timelines.
Rethinking the funding equation
For CFOs, the key question is not “What is the cheapest capital?” but:
- Can it be deployed when required?
- Is the approval genuinely executable?
- Does the lender understand mid-market realities and time pressure?
Non-bank lenders increasingly fill timing gaps, not quality gaps – complementing traditional finance rather than replacing it.
