A group of lenders has put forward a £4.4 billion (€5.0 billion) capital injection proposal to rescue Thames Water, Britain’s largest water utility, as the company battles severe financial strains and mounting environmental penalties, according to sources familiar with the plan.
The proposed deal, which is still subject to negotiation and regulatory approval, would convert existing debt into new equity to stabilise the utility’s balance sheet, enabling it to address long‑standing infrastructure issues and environmental obligations. The plan aims to keep the company operational while protecting service continuity for millions of customers across London and the south‑east of England.
Thames Water has faced intensifying pressures over recent years, including soaring debt levels, regulatory fines for sewage discharges, and criticism over ageing infrastructure, prompting concerns about its long‑term viability. Under the lenders’ proposal, creditors would take a larger ownership stake in the company in exchange for financial support.
The UK government and water industry regulator Ofwat are reviewing the proposal, weighing its implications for customers, investors, and environmental commitments. Officials have emphasised the need to safeguard reliable water services while ensuring accountability for pollution and infrastructure failures. Thames Water serves around 15 million customers, making its stability a significant concern for public water provision in England and Wales.
