Iran war impact to hit household energy bills for the first time

In July, household energy prices are poised to rise significantly due to increased wholesale costs attributed to the ongoing conflict in Iran, marking the first time these heightened costs will affect UK bills directly.

On Wednesday, regulator Ofgem is scheduled to release details regarding its latest price cap, which will influence millions of residences on variable tariffs across England, Scotland, and Wales.

Analysts anticipate a 13% increase in the current price cap, translating to an additional £209 annually for households consuming a typical amount of gas and electricity, leading to an overall bill of £1,850.

This announcement coincides with an unprecedented heatwave impacting much of the UK; however, experts contend that proactive measures can help mitigate bills later in the year.

The price cap is reviewed every three months. Following a government restructuring, domestic energy bills experienced a 7% reduction between April and July. This restructuring took place just before the onset of the turmoil in Iran. Nevertheless, the forthcoming cap for July to September will reflect a substantial 25% uptick in global gas prices, primarily driven by the effective closure of the Strait of Hormuz.

For households, the wholesale price paid by suppliers constitutes approximately 40% of their gas and electricity bills. Some energy suppliers have projected that energy prices may continue to escalate further as autumn and winter approach.

The government is currently devising strategies to offer targeted assistance to those most affected before energy costs surge further during the winter months, a period associated with increased household energy consumption.

Currently, a typical household is already facing a financial burden of around £600 annually compared to pre-2022-23 price levels. Meanwhile, billions in unpaid bills are owed to suppliers, and many individuals with disabilities require heightened energy usage year-round to operate specialized equipment.

The energy price cap oversees approximately 19 million households in England, Wales, and Scotland, noting that regulatory frameworks differ in Northern Ireland.

This cap establishes the maximum charge for each unit of gas and electricity under variable tariffs. Notably, millions of customers have fixed tariffs, which remain unchanged until the conclusion of their fixed terms.

Ofgem defines a "typical household" by calculating an annual bill predicated on the consumption of 11,500 kWh of gas and 2,700 kWh of electricity, payable via a single bill through direct debit.

Considering adjusting the perceived "typical" level of energy consumption, Ofgem intends to account for reductions in usage as many households have curtailed their consumption in response to elevated prices and improved energy efficiency.

While this adjustment may obscure the true spike in prices, it does not mitigate the reality that consumers will incur substantially higher costs per unit of energy.

According to forecasts from the energy consultancy Cornwall Insight, starting in July:

• The "typical" bill based on the current usage estimates is expected to reach £1,850 (an increase of £209 annually).
• Under potential new usage estimates, the "typical" bill would approximate £1,667. However, the current cap reflecting those estimates would be £1,490, thereby resulting in a similar increase.

Ofgem updated these typical domestic consumption values in 2019 and 2023.

Energy UK, representing energy suppliers, acknowledged that energy bills continue to be unaffordable for many individuals.

In response, companies have introduced repayment plans and allowed customers to take payment breaks as part of various support initiatives.

Experts assert that millions of households have adjusted their energy usage by lowering thermostat settings, taking shorter showers, sealing drafts, and finding ways to minimize heating needs in specific areas, all aimed at reducing bills.

Revisiting these energy-saving practices during this hot summer could prove beneficial when prices inevitably rise again.
