UK Firms Pull Fixed Energy Deals as Iran War Pushes up Prices

Why It Matters

The retreat from fixed‑price products reduces consumer protection against volatile bills and signals pressure on the UK price‑cap regime, potentially raising household energy costs.

Key Takeaways

• Fixed-price tariffs fell from 38 to 15 in a week.
• Remaining fixed deals rose up to £2,194 annually.
• 65 tariffs withdrawn this week, up from 14 prior.
• Only Octopus, EDF, and E.On keep fixed offers.
• Price cap could be hit if gas stays high.

Pulse Analysis

The latest escalation in the Middle East, sparked by the US‑Israel war with Iran, has sent global oil and gas markets into turmoil. Disruptions to production and transport routes have pushed wholesale energy prices to levels not seen since the 2022‑23 spike triggered by Russia’s invasion of Ukraine. In the United Kingdom, where households already face record‑high bills, suppliers are now grappling with a cost environment that makes long‑term price guarantees increasingly untenable. The UK’s reliance on imported gas amplifies the transmission of these shocks to domestic pricing.

Uswitch data shows the pool of fixed‑price tariffs collapsed from 38 on Saturday to just 15 by Thursday, while the price band widened to £1,640‑£2,194 per year. Suppliers such as Octopus have introduced temporary exit fees to recoup the higher wholesale spend, and British Gas is shifting customers toward flexible ‘Cap Tracker’ offers that stay below the regulator’s price cap. The industry’s trade body, Energy UK, warns that sustained high gas prices could force a revision of the cap, eroding a key consumer safeguard. Such moves also reflect a broader industry trend of shifting risk back onto consumers as margins tighten.

For consumers, the rapid disappearance of fixed deals means fewer options to lock in rates before the next price surge, increasing exposure to volatile wholesale swings. While variable‑tariff customers are temporarily insulated by the price cap until July, any upward pressure on the cap could translate into higher monthly bills across the board. Policymakers may need to reconsider the cap’s calculation methodology or introduce interim relief measures to prevent a wave of unaffordable energy costs, especially for vulnerable households. Energy watchdog Ofgem will monitor the situation closely, balancing market stability with consumer protection.
