Is your funding structure holding your business back?

Most founders and business owners spend a lot of time thinking about whether they have enough funding. Fewer ask a more important question: is the funding they already have actually right for where the business is now?

It is a distinction worth making. A facility that worked well two or three years ago may be quietly limiting the business today. Not because it has stopped functioning, but because the business has changed around it and the structure has not kept pace.

In the current UK market, where borrowing costs remain elevated and lenders are more selective than they were before 2022, the cost of carrying the wrong funding structure is higher than it used to be. Getting this right is no longer just a finance function. It is a strategic one.

‍

Funding structures are set at a point in time

When a business first accesses external finance, the facility it secures reflects the business as it was at that moment. The size, the trading history, the risk profile, the assets available, the lender relationships in place. All of those factors shape what is agreed and on what terms.

The problem is that businesses evolve. Revenue grows. The customer base changes. New assets are acquired. The trading model shifts. But the funding structure often stays the same, because reviewing it requires time and attention that tends to get deprioritised when the business is busy trading.

Over time, that gap between the business as it is and the funding structure it is carrying can become a real drag. It shows up in different ways depending on the business, but the underlying issue is the same. The facility is no longer fit for purpose.

The signs that a structure has been outgrown

There is no single indicator that a funding structure has become misaligned. It tends to reveal itself through a pattern of smaller signals that, taken individually, might seem manageable.

A business that is regularly hitting the ceiling of its overdraft is one sign. If the facility limit is being reached consistently, it suggests the working capital headroom available no longer reflects the scale of the business. Rather than managing within a comfortable buffer, the business is operating at the edge of what is available.

Consistently high interest costs relative to what the business is borrowing is another. The effective interest rate on new SME lending was running at over 6% in late 2025, but the rate a business pays depends heavily on how its facility is structured and which lender it is with. A business that has not reviewed its borrowing costs recently may be paying significantly more than it needs to.

Relying on short-term facilities to fund long-term needs is a structural mismatch that is more common than most businesses realise. An overdraft is designed to manage day-to-day cash fluctuations. It is not designed to carry persistent working capital requirements or fund assets that will be used over several years. Using short-term debt for long-term purposes is expensive and tends to create ongoing pressure rather than resolving it.

Carrying multiple facilities across different lenders, each taken out at a different point in time, can also signal that the overall structure has become fragmented. What started as a pragmatic response to a specific need can accumulate into a set of commitments that are harder to manage collectively and more expensive to service than a properly structured consolidated facility would be.

Why businesses do not review their funding more often

The most common reason is simply that it does not feel urgent. If the facilities in place are functioning, if payments are being met, and if the business is trading reasonably well, there is rarely an obvious prompt to sit down and review the overall funding structure.

There is also a degree of inertia in lender relationships. Businesses tend to stay with the lenders they know, partly out of familiarity and partly because exploring alternatives takes effort. That inertia can be expensive. The lending market has changed considerably over the past few years, with challenger banks now accounting for 60% of SME lending in the UK and specialist lenders offering products that high street banks either cannot or will not match.

A business that has not tested its options recently may be sitting with a more restrictive and more costly facility than it needs to be.

What a better structure can actually do

Reviewing and restructuring funding is not just about reducing cost, though that is often one of the outcomes. It is about ensuring the facility matches how the business actually operates.

A business with a strong and growing debtor book may find that moving to an invoice finance facility releases significantly more working capital than its current overdraft provides, without increasing its overall debt exposure. The facility scales with revenue rather than sitting at a fixed limit.

A business that has acquired assets over time may be able to use those assets as security to refinance existing unsecured debt at a lower rate, reducing monthly servicing costs and improving cash flow.

A business carrying multiple short-term facilities may benefit from consolidating into a single revolving credit facility with terms that reflect its actual trading pattern, simplifying its debt structure and reducing the overall cost of borrowing.

In each case the change is not dramatic. It is a question of alignment. Getting the right product for the right purpose at the right cost.

The role of lender appetite in this conversation

One factor worth understanding is that lender appetite shifts over time, and those shifts create windows of opportunity that businesses can take advantage of if they are paying attention.

The period from late 2024 through 2025 saw the Bank of England cut rates six times, bringing the base rate down from 5.25% to 3.75%. That cycle has now paused, with rates held at 3.75% and further cuts uncertain given inflationary pressures linked to the global energy market. But the rate environment is materially different to where it was two years ago, and businesses that secured facilities during the higher rate period may now be able to access better terms if they revisit their options.

At the same time, challenger banks and specialist lenders have continued to expand their appetite for SME lending. Businesses that were previously limited to high street bank facilities now have a broader range of options, often with more flexible terms and faster decision-making processes.

Approaching a funding review

A funding review does not need to be a major exercise. The starting point is simply mapping the current position clearly. What facilities are in place, what they cost, what their limits are, when they were set up, and whether the terms still reflect the business's current risk profile and trading position.

From there, the question becomes whether each facility is doing the job it is supposed to do. Is the overdraft providing genuine headroom or is it consistently maxed out? Is the cost of each facility appropriate given what the market currently offers? Is the overall debt structure sustainable and manageable as the business continues to grow?

Businesses that approach this conversation proactively, from a position of stability and good trading, tend to secure better outcomes than those that only review their funding when pressure is already building. Lenders assess risk based on the position of the business at the point of application. A business in a strong position has considerably more leverage in that conversation than one that is already under strain.

Final thought

Funding is not a set and forget decision. The business changes, the market changes, and what was appropriate at one stage of growth may quietly become a constraint at another. The businesses that manage their financial structure well are those that revisit it regularly, not just when something goes wrong.

In a market where borrowing costs remain elevated and lender options are broader than ever, the case for reviewing funding structure is stronger than it has been for some time.

Conclusion

The question is not just whether a business has access to funding. It is whether the funding it has is working as hard as the business is. A misaligned facility costs more than it should, provides less headroom than the business needs, and quietly limits what is possible. Reviewing structure regularly, and being willing to make changes when the business has outgrown what is in place, is one of the more straightforward ways to improve financial performance without changing anything about how the business trades.
