Summary:

• UK households face potentially higher winter energy bills as European countries seek to replenish depleted natural gas reserves.

• European wholesale gas prices exceeded €75/MWh, their highest level since late 2022.

• UK gas prices surpassed 185p per therm this week, also reaching their highest since late 2022.

• Renewed US-Iran fighting has increased concerns that disruption to the Strait of Hormuz will continue.

• Around one-fifth of global oil and liquefied natural gas normally passes through the Strait of Hormuz.

• Ofgem’s price cap will increase 4% in October, taking a typical household bill to £1,723 annually.

• Cornwall Insight forecasts household energy prices could rise another 9% in January if wholesale pressures persist.

• European countries delayed rebuilding gas reserves during summer because of elevated prices caused by the Iran conflict.

• Centrica warned Britain has very limited gas reserves and called for government support to expand its Rough storage facility.

• Energy prices will depend heavily on winter temperatures and how quickly shipping through the Strait of Hormuz recovers.

Why this matters: Higher gas prices could increase household costs during winter and add further inflationary pressure across the UK economy.

What’s next: Wholesale prices, European gas storage levels, winter weather and developments around the Strait of Hormuz will determine January’s energy price cap.
