The upcoming energy price cap for most UK households is projected to reach £1,929 annually in July, a figure lower than earlier estimates despite rising global tensions.
Recent and Upcoming Cap Adjustments
Regulator Ofgem sets the price cap every three months, limiting unit rates for energy on default tariffs. On April 1, the cap drops by £117 to £1,641 for a typical dual-fuel household with average usage. This April level was determined in February, prior to recent surges in wholesale prices.
The July cap, due for announcement in May, reflects higher wholesale oil and gas costs driven by the Middle East conflict. However, forecaster Cornwall Insight has revised its prediction downward to £1,929 from £1,973 announced on March 19. An earlier March 4 estimate stood at £1,801.
Factors Influencing the Forecast
Cornwall Insight attributes the reduction to a partial stabilization in wholesale markets, following a pause in energy infrastructure strikes and hints of a potential ceasefire. Disruptions in the Strait of Hormuz, a vital route for liquefied natural gas tankers, alongside damage to key oil and gas facilities, had previously spiked gas prices.
The firm states: “Unless wholesale prices fall below pre-conflict levels—which looks unlikely given the scale of disruption and the uncertain repair timeline to key infrastructure in the region—a higher price cap in July is effectively unavoidable.”
The increase from April’s £1,641 would total £288, or 18 percent. While volatility persists, current wholesale costs remain below 2022 peaks, distinguishing this from prior crises. Cornwall Insight adds: “The size of the increase depends on the duration of the conflict.”
Options for Households and Broader Impacts
Consumers can still secure fixed gas and electricity tariffs that undercut the April cap, even as some suppliers adjust offerings amid market shifts.
April’s cap change coincides with annual increases in water, broadband, and council tax bills. Elevated wholesale energy prices also threaten food costs, with analysts at the Institute of Grocery Distribution projecting grocery inflation at 8 percent by June if pressures continue.
