Ineos takes full control of Runcorn chlorine plant to safeguard UK water supply

Jim Ratcliffe's Ineos has agreed to purchase the remaining 50 per cent share of the Runcorn chlor‑alkali facility, giving the billionaire’s chemicals empire full ownership of a plant that supplies roughly 98 per cent of the chlorine used to treat drinking water across the UK. The transaction, announced on Friday by Ineos Inovyn, is expected to close by the end of 2026, subject to regulatory approval.

Why the deal matters

The Runcorn site is a linchpin of the nation’s water‑purification infrastructure. Chlorine produced there is mixed with salt‑derived chemicals to neutralise pathogens, a process that underpins safe tap water for millions of households. Losing the plant would have forced the country to look abroad for a vital commodity, potentially exposing the supply chain to geopolitical risk and higher costs.

In a statement, Stephen Dossett, chief executive of Ineos, said, "This agreement reflects our confidence in the long‑term future of the Runcorn site and its skilled workforce. Chlor‑alkali products are essential to modern life, supporting safe drinking water, pharmaceuticals and the materials that underpin housing and critical infrastructure."

Industry context and next steps

The acquisition comes as the British chemicals sector grapples with soaring energy prices and carbon‑related levies that have driven a 20 per cent contraction over the past three years. Energy taxes have been singled out by Jim Ratcliffe as a key factor stalling investment and pushing firms toward the brink.

Regulators will now review the deal for competition concerns, but the move is widely seen as a step toward stabilising the UK’s strategic chemical capacity. If approved, Ineos will likely invest in modernising the plant’s energy use, a move that could set a benchmark for other high‑cost manufacturers.

Looking ahead

With full control secured, Ineos is positioned to keep the Runcorn facility operating and to protect the domestic supply of chlorine and salt‑derived products. Analysts suggest the deal could encourage other investors to consider similar rescues of at‑risk industrial assets, helping to reverse the trend of off‑shoring critical capabilities.

The broader implication is a potential slowdown in the UK’s reliance on imported chemicals, a goal that aligns with government ambitions for greater industrial resilience.
