Conflict pushes companies struggling with rising costs in sectors such as steel and chemicals to the edge

n its 160-year history, Somers Forge’s furnaces in the Black Country have cast steel columns for the Bank of England, part of the anchor for the Titanic and – more recently – propeller shafts for Britain’s nuclear submarines.

The economic fallout from the Iran conflict is the latest of many geopolitical headaches the family-owned forge has endured, but it is already “very damaging”, said Tammy Inglis, the Somers finance director.

Energy was about a fifth of manufacturing costs at the forge, which employs 140 people in Halesowen, before the conflict began, but that proportion is now rising. “Everybody just battens down the hatches and spends what they absolutely need to spend,” said Inglis. “You’re in survival mode.”
