The ongoing conflict involving Iran and its repercussions have begun to ripple through the UK economy, impacting everything from fuel prices to mortgage rates. As tensions escalate, consumers are likely to face increased financial pressures. The impact will largely depend on how long the conflict persists and the resilience of global supply chains. Here’s a closer look at the areas most affected.
Fuel Prices Surge for Motorists
Motorists across the UK are already feeling the pinch at the petrol pumps, with prices on the rise since the conflict began. As of last Friday, the average cost of petrol reached 144.51p per litre, marking an increase of 11.7p since the onset of hostilities. Diesel prices have seen an even steeper rise, climbing by 23.9p to 166.24p.
This surge has sparked a contentious debate between petrol retailers and the government, especially after officials suggested that some companies might be taking advantage of the situation to inflate prices. Industry analysts assert that a $10 increase in the price of crude oil typically translates to an additional 7p at the pump. Given the current volatility in oil prices, it is plausible that average petrol costs could hit 150p per litre if the situation remains unchanged.
While industry experts assure that fuel supplies are adequate, they recommend that drivers limit non-essential travel and adjust their driving habits to enhance fuel efficiency.
Mortgage Rates on the Rise
As the conflict intensifies, the mortgage market is reacting sharply. Prior to the outbreak of hostilities, there were expectations for a gradual decline in interest rates for both fixed and variable mortgages. However, lenders have swiftly adjusted their rates upwards in response to rising funding costs and a reassessment of future base rate movements.

Currently, the average two-year fixed mortgage rate has escalated from 4.83% at the beginning of March to 5.35%, the highest it has been since the previous March. For those considering a five-year fixed rate, the average has increased from 4.95% to 5.39%. Homebuyers are now facing an additional annual cost of £788 based on a standard 25-year mortgage of £250,000, reflecting current rates.
The uncertainty in the market has led to lenders withdrawing approximately 1,000 residential mortgage products. Despite this, there remain over 6,600 options available. Adam French, head of consumer finance at Moneyfacts, noted that pulling products often signals that funding costs are fluctuating too rapidly for lenders to adapt their pricing accordingly.
Energy Costs and Household Bills
Households currently benefit from a price cap on gas and electricity bills, enforced by the energy regulator Ofgem, but this measure is set to expire in July. While there are indications that prices may decrease in the short term, the longer-term outlook depends heavily on the wholesale energy market’s performance in the coming months. If wholesale costs remain elevated, millions could see their energy bills skyrocket.
Cornwall Insight forecasts that under Ofgem’s price cap for the July to September period, average dual-fuel households could see their annual bills rise to £1,973, up from £1,641. Energy Secretary Ed Miliband has indicated that the government is prepared to intervene if necessary, though any assistance will likely target the most vulnerable consumers.
For those using heating oil—common in rural regions and Northern Ireland—costs are entirely unregulated, leading to potential financial strain. Prime Minister Sir Keir Starmer announced a £53 million support scheme for vulnerable heating oil users, with funding distributed through local councils.
The Broader Economic Landscape
At the beginning of March, UK inflation was projected to hover around the Bank of England’s target of 2%, but these forecasts have since been upended by the conflict. Analysts now anticipate a rise in inflation rates, though they do not expect a return to the peak of 11.1% seen in October 2022. The current situation complicates economic predictions, making it difficult to gauge the full impact of the conflict on inflation.
Interest rates are also poised for potential increases rather than the anticipated cuts, as the Bank of England’s primary objective remains controlling inflation. While borrowing might become more costly, there may be slight advantages for savers in this volatile environment.
Why it Matters
The ongoing conflict in Iran is not merely a distant geopolitical issue; it has tangible effects on everyday financial decisions for UK consumers. As fuel and mortgage rates climb, alongside potential spikes in energy bills, the cost of living is poised for further strain. Understanding these dynamics is essential for consumers navigating a rapidly changing economic landscape, as they prepare for the possibility of higher living costs in the months ahead.
