UK Energy Bills Could Surge by £160 as Iran Conflict Pushes Gas Prices Higher
Household energy costs in Great Britain are projected to rise by £160 per year starting this summer, potentially reaching £1,800 annually under the government's quarterly price cap from July. This increase follows a sharp spike in the UK's gas market, which has hit a three-year high due to escalating tensions in the Middle East.
Analysis Points to 10% Increase in Energy Costs
According to analysis by Cornwall Insight, a leading energy consultancy, household energy expenses could surge by 10% after gas prices doubled in the days following a US-Israeli attack on Iran. In retaliation, Tehran has halted oil and gas shipments through the Strait of Hormuz, a critical global transit route.
The unit cost of gas and electricity will remain stable over the coming months, as Ofgem, the energy regulator, fixed household energy costs at £1,641 per year for the period from April to July. This represents a £117 reduction from the January-March cap, though it falls short of the £150 annual cut promised by Chancellor Rachel Reeves in last year's budget.
Ofgem to Recalculate Costs Amid Market Volatility
Ofgem is set to recalculate the costs faced by energy suppliers for the next quarter, taking into account the recent rise in market prices. Jonathan Brearley, chief executive of Ofgem, informed MPs that it is "genuinely too early to tell" how high energy bills may climb, as this will depend on the duration of elevated wholesale prices.
Brearley warned that if the Strait of Hormuz—which handles about 20% of global oil supplies and seaborne gas shipments—remains closed for a prolonged period, it would create "significant upward pressure" on energy bills. However, he noted that the UK is in a "significantly stronger position" than before the 2022 Russia-Ukraine crisis, thanks to a more diverse range of gas sources.
Broader Impact on Consumers and Motorists
Motorists are already feeling the pinch, with petrol prices rising by 2.5p per litre since Saturday and diesel climbing by over 3p, following a global oil benchmark increase above $81 a barrel. The UK's energy markets have experienced some of the steepest price rises globally, attributed to the country's heavy reliance on gas for electricity generation and limited gas storage capacity.
Government Response and Industry Warnings
Energy Secretary Ed Miliband stated that the government is closely monitoring the situation in oil and gas markets. He emphasized, "Conflict in the Middle East is yet another reminder that the only route to energy security and sovereignty for the UK is to get off our dependence on fossil fuel markets, whose prices we do not control, and onto clean homegrown power we do."
Market experts have highlighted the UK's vulnerability to market volatility compared to continental Europe. Andreas Schroeder, head of gas analytics at ICIS, explained, "The big difference between Britain and continental Europe is the availability of gas storage. Abundant storage in central Europe helps as a buffer and cushion against price shocks out in the world."
Tom Marzec-Manser, a director at consultancy Wood Mackenzie, added that the closure of Britain's last coal-fired power plants limits the UK's ability to switch from gas to coal generation, unlike some European countries.
Calls for Renewable Energy Investment
Craig Lowrey, principal consultant at Cornwall Insight, argued, "Events like this reinforce the case for greater home-grown renewable generation. Reducing the UK's reliance on volatile global gas markets is the most durable way to protect households from future price shocks."
In related developments, Chancellor Rachel Reeves met with North Sea industry leaders to discuss the upheaval in global energy markets. A government source indicated that Reeves remains committed to ending the energy profits levy, though the Middle East crisis has delayed plans due to its impact on oil and gas prices.
