Farmers across the UK are grappling with steep rises in fertiliser and fuel costs, jeopardising their ability to maintain affordable produce. The escalating prices stem from ongoing geopolitical tensions in Iran and surrounding Gulf states, resulting in a volatile energy market. As oil prices surged to over $100 per barrel last week, governments have begun tapping into emergency reserves to mitigate the crisis. Andrew Williamson, who operates a 900-acre arable farm near Bridgnorth in Shropshire, voiced his deep concerns regarding the financial sustainability of the farming sector as these costs continue to rise.
The Pressure of Rising Input Costs
Williamson, who cultivates a diverse range of crops including wheat, barley, and oats, acknowledged that many arable farms had managed to secure their fertiliser at last year’s prices. However, he remains apprehensive about the impact of current market conditions on next year’s yield, particularly as he prepares to purchase the necessary fertiliser later this year. “We are already struggling to break even and cover our cost of production,” he stated. “The rising price of fertiliser makes that even more difficult.”
The situation has been compounded by two consecutive poor harvests, adding to farmers’ woes. Williamson noted that the price of nitrogen fertiliser, which is heavily reliant on natural gas, has surged by approximately 50% since he last stocked up in July 2025. “Rather than being £330 a tonne, it’s now £490 a tonne,” he lamented.
The Strain on Livestock Farmers
While arable farmers like Williamson have some buffer due to prior purchases, livestock farmers are facing even harsher realities. They typically buy fertiliser as needed, meaning they are directly impacted by the escalating prices. Williamson described the situation as “hammering” livestock producers, who now confront heightened operational costs without the benefit of advance purchasing.

Williamson expressed his frustration at the unpredictability of farming investments, stating, “Farming is a long-term investment; we’re two years from when we purchase things to when we see a return from it.” This uncertainty heightens the risks associated with every decision farmers make, adding to the anxiety within the agricultural community.
A Call for Transparency
In addition to fertiliser costs, rising prices for red diesel—a fuel used to power agricultural vehicles—are further squeezing the farming sector. Although red diesel enjoys a reduced fuel duty rate, it has seen a significant price jump of about 50% since the onset of the conflict in Iran. Williamson remarked that unlike fertilisers, fuel costs are continuously incurred, amplifying the financial strain on farmers.
He has called for greater transparency within the fuel supply chain, criticising the erratic nature of price changes. “We are unfortunate as an industry; we can’t automatically pass on our costs,” he explained. “We’re price-takers, not price-setters.” This lack of control over pricing dynamics is a persistent challenge for farmers, who find themselves at the mercy of market fluctuations.
Consumer Implications
As farmers grapple with these unprecedented cost increases, consumers can expect to feel the repercussions in grocery aisles. Williamson highlighted that while the commodity prices may appear stable, the overall cost structure for farming has shifted dramatically, creating a ripple effect that will ultimately reach consumers. “If you look at the value of wheat in a loaf of bread, it’s very small,” he noted, underscoring the complexity of pricing within the agricultural supply chain.

The government has recently faced criticism over potential price gouging in the fuel sector, with Energy Secretary Ed Miliband asserting that profiteering amidst the ongoing conflict will not be tolerated. This scrutiny of the fuel industry may provide some relief to farmers if it leads to more stable pricing structures.
Why it Matters
The rising costs of fertiliser and fuel serve as a stark reminder of the interconnectedness of global events and local economies. As British farmers face unprecedented challenges in maintaining production levels and affordability, the implications for food security and consumer prices become increasingly concerning. The agricultural sector’s ability to adapt to these pressures will not only determine the viability of individual farms but also the stability of the food supply chain as a whole.
