British households are facing a substantial increase in energy bills starting in July, with forecasts suggesting a rise of over £200 due to the ongoing conflict in Iran. The energy price cap, which is set to be announced by Ofgem, is expected to increase to £1,850, representing a 13% jump from the previous cap of £1,641. This rise is attributed to the blockade of the Strait of Hormuz, a critical shipping route for oil and gas. While the summer months may provide some temporary relief, concerns are growing regarding the upcoming October review, as demand for energy typically surges in winter. Despite calls for government action to support vulnerable households, Chancellor Rachel Reeves has not committed to immediate measures, stating that the government is prepared to act if market conditions worsen. Campaigners have expressed urgency for the government to clarify support options before winter arrives, warning that many households could face an extremely challenging season without additional assistance.
