UK ministers are weighing how to shield households from soaring energy costs as global prices surge following the Iran war. Prime Minister Sir Keir Starmer has not ruled out intervention, but officials say the government will likely wait until the current price cap rises in July before acting. The cap for April to June is already set at £1,641 for a typical household, with projections suggesting it could exceed £1,800 by summer.

Analysts warn that without targeted support, millions of families face a severe cost-of-living shock. The Resolution Foundation argues that freezing fuel duty would be ineffective since fuel costs disproportionately affect wealthier households. Instead, the think tank proposes a £3.75 billion annual 'social tariff' that would discount energy unit prices for lower-income families without fixed-rate deals. This approach would protect the poorest fifth of households while maintaining incentives for energy conservation.

Government intervention remains controversial after the UK spent approximately £35 billion on universal energy support following Russia's invasion of Ukraine, which is now seen as fiscally unsustainable. Labour Together suggests more aggressive measures including a temporary 2p income tax increase to prevent any bill rises. However, economists caution that blanket price caps would strain public finances and reduce conservation incentives. With Ofgem's next price cap announcement looming and political pressure mounting, ministers must balance immediate relief against long-term fiscal stability and energy transition goals.
