Ofgem Price Cap to Hike UK Household Energy Bills by 13% Due to Iran War

Household energy prices in the UK are set to experience a sharp increase in July, as the impact of the conflict in Iran directly affects consumer bills for the first time. Regulator Ofgem is scheduled to release details of its updated price cap, which will govern millions of homes on variable tariffs across England, Scotland, and Wales.

Industry analysts forecast a 13% rise on the current cap. This adjustment would translate to a typical household paying an additional £209 per year, bringing their annual energy expenditure to £1,850. The forthcoming announcement coincides with a record-breaking heatwave across significant parts of the UK; however, experts advise consumers to implement energy-saving measures now to mitigate higher costs later in the year.

The price cap undergoes quarterly revisions. While domestic energy bills saw a 7% reduction between April and July following government reforms, the July to September cap will reflect the 25% surge in global gas prices attributed to the Iran war, particularly the effective closure of the Strait of Hormuz. Wholesale prices, paid by energy suppliers, constitute approximately 40% of a household's gas and electricity bill. Certain energy providers have indicated that prices could climb further into the autumn and winter months.

The government has stated it is formulating plans for targeted support for vulnerable households before winter, when energy consumption typically increases. Currently, a typical household already pays roughly £600 more annually than before the price shocks of 2022-23. Billions of pounds are reportedly owed to suppliers in unpaid bills, and many individuals with disabilities incur high energy usage year-round for essential specialist equipment.

The energy price cap applies to around 19 million households in England, Wales, and Scotland; Northern Ireland operates under different regulations and billing structures. The cap sets the maximum unit charge for gas and electricity on variable tariffs. Millions of customers on fixed tariffs remain unaffected until their agreements conclude.

Ofgem calculates the cap based on the annual bill of a 'typical household' consuming 11,500 kWh of gas and 2,700 kWh of electricity per year, with payments settled via direct debit. The regulator is currently assessing whether to reduce its definition of 'typical' energy use, noting that many households have curtailed consumption due to high prices in recent years and improved energy efficiency. Such a redefinition could obscure the underlying sharp price increases, but would not alter the fundamental reality that consumers will pay considerably more for each unit of energy consumed.

Energy UK, representing suppliers, reiterated that energy bills remain unaffordable for many. However, the organisation stated that companies offer struggling customers repayment plans and payment breaks as part of various support mechanisms. Experts suggest that millions of households have already adopted measures such as lowering radiator and thermostat settings, taking shorter showers, sealing draughts, and limiting heating in certain rooms to reduce costs. They advise that similar preparations made during the summer to revisit these habits and enhance home energy efficiency could prove beneficial as prices continue to ascend.
