Can’t Afford Fuel for Your Business? What UK Directors Should Do

If your business cannot afford fuel, you are not dealing with a small inconvenience. 

For many UK companies, especially those in logistics, haulage, delivery, construction, engineering, field services, and wider supply-chain operations, fuel is a core trading cost. When it becomes hard to cover, that is often a sign that cash flow is under real pressure.  

Right now, that pressure is being made worse by a sharp rise in oil and fuel prices linked to the current Middle East conflict, disruption around the Strait of Hormuz, and wider supply-chain uncertainty.

Reuters has reported that the conflict has pushed fuel prices higher across multiple markets, while RAC data shows UK forecourt prices have risen rapidly since late February, with diesel being hit particularly hard.  

For stressed directors, this matters because fuel problems rarely stay as fuel problems. They quickly spill into missed jobs, delayed deliveries, lower margins, strained supplier relationships, and growing creditor pressure. In sectors where vehicles are essential to keep the business moving, rising fuel costs can turn an already fragile company into one facing serious financial distress.  

This guide explains what it means if your business cannot pay for fuel, why the current war-related price shock makes the issue more serious, what directors should do immediately, and when it may point to insolvency. 

Fuel costs were already a major operational pressure for many businesses before the current geopolitical shock. But recent events have made the situation worse. 

Reuters reported on 18 March 2026 that the conflict involving Iran, Israel, and the United States has disrupted shipping through the Strait of Hormuz and lifted oil prices sharply. The same Reuters reporting said UK fuel prices were up around 7%, with other markets also seeing steep increases.  

In the UK, RAC figures published on 11 March 2026 said average unleaded had risen to around 139p per litre, while diesel had climbed to 155.1p per litre. RAC added that diesel had increased by nearly 13p, or 9%, since 28 February and had reached its highest level since May 2024. A further RAC update said average prices had “rocketed” in under two weeks, with petrol up 7p to 140p and diesel up 16p to 158p.  

That matters because diesel-heavy sectors are often the ones least able to absorb sudden price rises. Logistics, transport, courier businesses, plant hire, construction, and mobile service firms depend on fuel not as a discretionary expense, but as a daily requirement for trading.  

When those costs spike quickly, businesses with weak margins or tight cash flow can get caught out fast. Logistics UK has long highlighted fuel as a significant component of fleet expenditure, and that basic commercial reality becomes even more dangerous when markets are volatile.  

If your company sits anywhere in the logistics or supply-chain chain, rising fuel prices can hit from several directions at once. 

First, there is the obvious direct cost. Every van, lorry, fleet vehicle, delivery route, or site visit becomes more expensive overnight. 

Second, there is knock-on disruption. If shipping lanes are affected, oil supply is disrupted, or international transport becomes less predictable, businesses can face delays, increased import costs, pricing volatility, and reduced confidence across supply chains. Reuters has repeatedly linked the current conflict to shipping disruption and risks around Hormuz, which is a vital route for global oil flows.  

Third, there is margin compression. Many businesses cannot simply pass every extra cost on to customers immediately. Existing contracts, competitive pressure, and customer resistance may leave directors absorbing higher fuel bills without any equivalent rise in revenue. 

That is why logistics and supply-chain firms are likely to suffer disproportionately. They are exposed to fuel costs directly, and they are also exposed to the wider ripple effects of war-driven energy disruption. 

If your business cannot afford fuel, there are usually three broad possibilities. 

You may be waiting on a major payment, dealing with a poor month, or facing a temporary mismatch between money coming in and money going out.

In that case, the business may still be viable, but under short-term strain. 

If the company cannot pay essential trading costs as they fall due, that can point to insolvency.

A fuel card being declined, suppliers chasing, tax arrears building, and the bank balance never recovering are not just operational headaches. Together, they may indicate that the company is no longer financially stable. 

You may be waiting on a major payment, dealing with a poor month, or facing a temporary mismatch between money coming in and money going out.

In that case, the business may still be viable, but under short-term strain. 

If your business cannot afford fuel, there are practical steps to take straight away. 

If vehicles are necessary for the business to generate revenue, fuel is likely to be a priority cost. But that should be reviewed alongside every other outgoing. Cut or pause non-essential spend quickly where possible. 

A lot of companies in trouble have cash tied up in unpaid invoices. Faster collections will not solve every problem, but they can create breathing space at the exact moment the business needs it most. 

Silence usually makes things worse. If a supplier relationship matters to your trading continuity, proactive communication is normally better than waiting until accounts are frozen or terms are withdrawn. 

It is common for directors to pay for fuel personally when the company account is under strain. As a one-off emergency measure, that may happen. But if it becomes a pattern, it often means the company has a structural cash flow or insolvency problem. 

Yes, a director can sometimes pay for business fuel personally and reclaim the expense later, provided it is genuinely for business use and recorded properly. 

But this should be treated with caution. 

If you are repeatedly paying for fuel out of your own pocket to keep the business going, that is usually not a sustainable fix. It may help the company limp on, but it does not solve the underlying issue. It can also create accounting complications if not handled correctly. 

The more important question is this: why can the company no longer fund one of its most basic operating costs? 

Sometimes directors think another credit line, card, or short-term facility will get them through. 

That may be reasonable if the business is healthy overall and the pressure is genuinely temporary. 

But if the company is already juggling debts, suffering weak margins, and facing rising supplier pressure, borrowing more just to cover fuel can make the eventual outcome worse. More debt does not cure an unviable business model or a deteriorating cash flow position. 

If the business is struggling with fuel because of a wider debt or cash flow problem, the right option depends on viability, creditor pressure, and how quickly action is taken. 

Possible options may include: 

Cost reduction, better collections, renegotiated supplier terms, price reviews, tighter operations, and realistic forecasting may help where the business is still fundamentally viable. 

Some suppliers or creditors may agree short-term support, though this depends on trust, the sums involved, and whether the company still looks recoverable. 

For some companies, there may be a route through a Company Voluntary Arrangement or administration, depending on the size, structure, and viability of the business. 

If the company is insolvent and there is no realistic prospect of recovery, liquidation may be the most responsible way to close the business and deal with creditor pressure properly. 

If your business cannot afford fuel right now, this is not something to brush aside. 

The current war-driven rise in oil and fuel prices has made an already difficult trading environment even tougher for UK businesses. Reuters has linked the conflict and disruption around the Strait of Hormuz to higher oil prices, while RAC data shows that UK petrol and diesel costs have risen sharply in recent weeks, with diesel seeing particularly heavy increases.

That creates a serious problem for any business that relies on vehicles, deliveries, or supply-chain continuity.  

For logistics and supply-chain businesses, the threat is even greater. Rising fuel bills do not just squeeze margins. They can disrupt operations, delay customer delivery, weaken cash flow, and bring wider financial problems to the surface. 

If fuel is becoming unaffordable, the key is to treat it as an early warning sign. Review the numbers properly, act quickly, and get advice before the problem spreads into something much harder to control.
