UK Businesses Brace for Energy Cost Surge as Iran Conflict Drives Fuel Prices Higher
British businesses are facing a mounting cost crisis as the ongoing US-Iran conflict continues to drive fuel and energy prices to levels not seen in years, with diesel averaging 170 pence per litre and energy bills projected to rise by 18% from July.
The Scale of the Crisis
The closure of the Strait of Hormuz — a critical chokepoint for global oil and gas transport — has sent shockwaves through UK energy markets. Brent crude has risen more than 60% above pre-conflict levels, while European and UK natural gas prices are more than 70% higher. For UK businesses, particularly those in transport, hospitality, retail, and manufacturing, the impact is being felt acutely.
Tradespeople are among the hardest hit, with over a third of sole traders and small contractors telling industry groups they fear business failure if fuel costs remain at current levels. The Road Haulage Association has described the situation as a national emergency, warning that the cost of moving goods across the UK is becoming unsustainable.
Wider Economic Pressures
The energy shock is compounding a series of other cost pressures on UK businesses. The National Living Wage rose to £12.71 per hour on 1 April, and today's Employment Rights Act changes — including day-one sick pay rights — add further obligations. Business rates increases and higher employer National Insurance contributions, introduced in the October 2025 Budget, are also weighing on margins.
Data from the Office for National Statistics (ONS) showed that real household disposable income declined by 1.2% in 2025, signalling weaker consumer spending ahead. In the hospitality and retail sectors, job cuts are already emerging, with William Hill announcing plans to close 15% of its stores.
Government Response
The government has frozen fuel duty and extended the fuel allowance, but business groups argue these measures are insufficient given the scale of the price surge. Foreign Secretary Yvette Cooper held a meeting with representatives from over 40 nations to discuss reopening the Strait of Hormuz, though no firm agreement has been reached. The FTSE 100 staged a partial recovery on 1 April, rising 1.58% to 10,336.93, as markets responded to reports of potential de-escalation — but analysts warn the underlying situation remains fragile.
Why It Matters
For UK consumers and businesses alike, the energy cost surge is the most immediate economic challenge of 2026. With energy bills set to rise further in July and no clear resolution to the Iran conflict in sight, the pressure on household budgets and business cashflows is likely to intensify before it eases.
What's Next
The government is expected to announce further cost-of-living support measures in the coming weeks. The Bank of England's Monetary Policy Committee, which held the Bank Rate at 3.75% in February, faces a difficult balancing act between supporting growth and keeping inflation in check as energy prices push upward.
