The British Government is under mounting pressure to shield households from a sharp rise in energy costs, as the escalating conflict in Iran disrupts global oil and gas supplies. Millions of families face higher bills this winter, with analysts warning that the impact could be the most severe since the 1970s oil crisis.
The conflict, which has seen attacks on key energy infrastructure in the Strait of Hormuz, has sent crude oil prices soaring by over 20% in the past month. Natural gas prices, already volatile due to the war in Ukraine, have followed suit. The UK, heavily reliant on imported energy, is particularly exposed. Wholesale gas prices, which have already risen by 150% since 2021, are expected to climb further.
According to the Institute for Energy Economics, the typical household energy bill could increase by £300 to £500 per year from April, when the price cap is next adjusted. This would add to the cost-of-living crisis, pushing millions into fuel poverty. Charities and opposition MPs are calling for immediate government intervention, including a windfall tax on energy profits and expanded support for vulnerable households.
Energy Secretary Claire O’Neill acknowledged the challenge in a statement today, saying the government is “monitoring the situation closely” and “considering all options” to protect consumers. However, critics argue that the government has been too slow to act. “We need a comprehensive plan, not just words,” said Sarah Green of the Fuel Poverty Coalition. “People are already choosing between heating and eating.”
The crisis underscores the UK’s vulnerability to geopolitical shocks. Despite progress on renewables, the nation still relies on gas for more than 40% of its electricity and heating. The conflict in Iran, a major oil producer, has exacerbated supply constraints. The Strait of Hormuz, through which about 20% of the world’s oil passes, has seen attacks on tankers, forcing insurers to hike premiums and some shipping companies to divert routes.
Scientists at the National Energy Research Centre have modelled the impact of a prolonged disruption. Their worst-case scenario shows energy bills doubling, with severe consequences for the economy and public health. “This is a stark reminder of the fragility of our energy system,” said Dr. Helena Vance, Science and Climate Correspondent. “We must accelerate the transition to homegrown renewables and storage technologies to insulate ourselves from such risks.”
The situation is a test of the government’s commitment to net-zero targets. While ministers have emphasised investment in wind and solar, critics say the pace is too slow. The UK’s energy security strategy, published last year, aimed to boost nuclear and renewables, but many projects remain years away from completion.
In the interim, the government faces tough choices. Options include expanding the Warm Home Discount, increasing winter fuel payments, or temporarily cutting VAT on energy bills. Labour has proposed a windfall tax on oil and gas companies, which have seen record profits. The government has resisted such measures, arguing they could deter investment in domestic production.
The International Energy Agency has warned that the energy crisis is far from over. With winter approaching, the pressure is on for the UK to act swiftly. As Dr. Vance noted, “Every kilowatt-hour saved now is a step toward resilience. We cannot afford to wait.”
