The UK is heading into another period of rising living costs, and the driving force is once again energy. After a brief period of relief, the energy price cap set by Ofgem is expected to increase again from July 2026, reversing recent declines. This is setting off a chain reaction that will reach far beyond household utility bills most notably into the price of food.
Current projections suggest the cap could rise by around £200-£300 annually for a typical household, pushing average bills back toward £1,800–£1,900 per year. While this may not match the extreme peaks seen during earlier crises, the direction of travel is clear. Energy costs are climbing again, and they are doing so at a time of heightened global uncertainty. Disruption to oil and gas markets—linked in part to tensions around the Strait of Hormuz—is feeding directly into wholesale prices, which in turn shape the cap reviewed each quarter.
But the real economic story begins once those higher energy costs start filtering through the wider system. Nowhere is this more visible than in food production. Even food grown within the UK is deeply dependent on energy at almost every stage.
Greenhouses require heating and lighting, particularly for crops like tomatoes, cucumbers, and peppers. Fertiliser production relies heavily on natural gas, farm machinery runs on diesel, and harvested food must be stored, processed, and transported—often under refrigeration.
As energy prices rise, so too do these input costs. Farmers face difficult choices: absorb the increase, raise prices, or cut production. In many cases—especially for energy-intensive crops—reduced output becomes the only viable option. This has already led to warnings that some UK growers may scale back or even halt production, raising the risk of tighter supply alongside higher prices.
The effects do not stop at the farm gate. Food processing plants, packaging facilities, and supermarket distribution networks are all energy-intensive. Higher electricity and fuel costs ripple through the entire supply chain, meaning that even modest increases in wholesale energy prices can translate into noticeable changes on supermarket shelves. As a result, UK food inflation is expected to remain elevated, with estimates suggesting increases of around 5–10% across many categories.
Some foods are particularly exposed. Fresh produce grown in heated greenhouses—such as tomatoes, cucumbers, and salad vegetables—is among the most vulnerable. Dairy products may also rise in price due to higher feed and energy costs, while meat prices could increase as farmers face more expensive inputs. Even staple items like bread are affected, as energy plays a role in both fertiliser production and baking.
What makes this situation especially challenging is that "locally produced" food offers little protection. UK farmers operate within the same global energy market, meaning they face the same cost pressures as producers elsewhere. In some cases, imported food may even become more competitive, depending on how different countries are affected by the same energy shock.
The broader economic implications are significant. Rising energy costs push up food prices, which in turn contribute to overall inflation. This creates a difficult environment for policymakers, including the Bank of England, as they attempt to balance inflation control with the need to support economic growth.
In the months ahead, much will depend on how global energy markets evolve. If supply stabilises and prices ease, the pressure on both energy bills and food costs may begin to subside. But if current tensions persist or escalate, UK households are likely to face a renewed squeeze paying more not only to heat their homes, but also to fill their shopping baskets.
The connection is clear and unavoidable: when energy prices rise, the cost of living rises with them.
