Due to the conflict involving Iran driving up wholesale natural gas and electricity costs, UK households are set to face the largest increase in energy bills since 2023. This will further intensify inflationary pressures and weigh on the overall economy.
The UK's energy regulator, Ofgem, announced on Wednesday that the energy price cap will rise by 13% starting July 1, reaching £1,862 (approximately $2,505). The price cap, which sets the maximum rate suppliers can charge households, is adjusted quarterly. This increase is the first to fully reflect the impact of the Middle East turmoil, as previous caps were based on market data from before the escalation.
Since the outbreak of the conflict involving Iran earlier this year, European energy prices have surged, with concerns over disruptions to oil and gas shipments through the Strait of Hormuz. Since the conflict began, UK one-month natural gas futures have risen over 40%, while electricity futures have increased by nearly one-third.
Energy bills in the UK are now rising at the fastest pace since 2023. Typically, the price cap decreases during the summer due to lower demand, making this summer's hike unusual. Energy consultancy Cornwall Insight forecasts another increase in energy bills in October. The firm warns that even if the conflict ends swiftly, electricity prices are unlikely to return to April levels due to infrastructure damage and ongoing supply disruptions.
Craig Lowrey, Principal Consultant at Cornwall Insight, stated, "The summer increase is already putting pressure on households, but a larger concern looms in October when residential energy demand rises." The firm's preliminary forecast suggests the price cap could rise by a further 2% in October, reaching £1,899.
The surge in energy costs has fundamentally altered the inflation outlook for the Bank of England, reminiscent of the energy shock triggered by the Russia-Ukraine conflict. Prior to the Iran conflict, the Bank of England had anticipated inflation would gradually decline toward its 2% target this spring, allowing for further interest rate cuts. Now, even under more optimistic scenarios, the central bank expects price growth to remain close to double the target level later this year.
Influenced by higher fuel prices, UK inflation held steady at 2.8% in April. Rising energy costs have forced the Bank of England to postpone plans for rate cuts. Several Bank of England officials have recently warned that, should the conflict persist, a rate hike cannot be ruled out. The central bank is currently weighing whether a weak labor market and sluggish economic conditions can offset the risk of a new inflationary spiral triggered by rising energy prices.
UK Energy Secretary Ed Miliband stated in a declaration, "This unwanted conflict has driven up the energy price cap, which is undoubtedly bad news for households nationwide." The UK government is formulating plans to provide targeted support to the public in the second half of the year to alleviate household energy cost burdens. Miliband added on Wednesday that the government will "be fully prepared" before winter arrives.
Despite recent declines in the energy price cap over recent months, the scale of household energy debt continues to expand, as broader cost-of-living pressures make it difficult for many families to pay their bills on time. The UK's Energy and Utilities Alliance estimates that debt could reach £7 billion by the end of 2026.
Simultaneously, the UK's economic growth prospects have weakened. Surveys indicate economists expect the UK economy to grow by 0.7% in 2026 and 1.2% in 2027, both figures lower than previous forecasts. Additionally, political instability may cast a shadow over the UK's economic outlook. In local elections held earlier this month, the ruling Labour Party, led by Prime Minister Keir Starmer, suffered significant setbacks, with a large number of party MPs defecting. Following the election defeat, Labour MPs have publicly called for Starmer's resignation.
Overall, the Bank of England finds itself at a policy crossroads, unable to ease due to persistent inflation and unable to tighten significantly due to signs of economic slowdown, with geopolitical risks further limiting its policy flexibility. The Bank of England is scheduled to announce its interest rate decision on June 18. Markets currently expect the central bank to keep the benchmark rate unchanged at 3.75%.
