Key Highlights

  • UK gas fell over 2% to around 118.5 pence per therm, easing from a four-week high.
  • Prices had climbed roughly 15% earlier in the week after fresh US strikes on Iranian targets.
  • Hormuz shipping disruption threatens Europe's — and by extension Britain's — winter storage plans.

UK natural gas prices fell more than 2% to around 118.5 pence per therm on Friday, easing from a four-week high, after reports emerged that negotiations between the United States and Iran were continuing despite the recent escalation in hostilities between the two countries. The retreat offered a modest reprieve after a volatile stretch for the market.

A US official reiterated that Washington remains committed to reaching a diplomatic solution with Tehran, a statement that helped calm fears of a renewed full-scale conflict capable of threatening energy supplies flowing out of the Persian Gulf. That message, while not resolving the underlying tension, was enough to take some of the edge off prices.

The move follows a sharp run-up earlier in the week, when prices climbed about 15% after fresh US strikes on Iranian targets — launched in response to attacks on vessels transiting the Strait of Hormuz — triggered retaliatory Iranian strikes on American bases in the region. That sequence of events pushed UK gas to its highest level in a month, reflecting how directly British energy costs are tied to developments thousands of miles away.

The connection runs through global LNG markets. The UK relies on seaborne LNG cargoes to supplement pipeline supply, and the Strait of Hormuz handles roughly one-fifth of global oil and LNG trade. Any disruption to shipping through the strait ripples quickly into European and British gas prices, given how tightly interlinked global LNG markets have become since Europe pivoted away from Russian pipeline gas.

With Europe — and the UK alongside it — in the midst of the seasonal push to replenish gas inventories ahead of winter, markets remain closely focused on shipping activity through the strait. Any renewed disruption would complicate that restocking effort, leaving UK gas prices vulnerable to further swings as the US-Iran situation continues to develop.
