Thames Water, the UK’s largest water company, edged toward a form of nationalisation after the government objected to a rescue package proposed by the firm’s lenders. Environment Secretary Emma Reynolds wrote to the industry regulator on Monday to express concerns about the terms of the lender-led turnaround plan. The government has long warned it could step in if necessary, with fears of a collapse having persisted for about three years. A government spokesman told the BBC that the current offer “does not do enough to protect consumers or the environment.”

The company, which serves around 16 million customers mainly in London and parts of southern England, has faced sustained criticism over performance, sewage discharges and leaks. In May last year it received a £122.7 million fine—the largest in the water sector for breaches of sewage-spill rules and shareholder payouts. A group of existing lenders has proposed writing off roughly 30% of Thames Water’s debt burden, close to £20 billion, and injecting billions in new capital, while seeking leniency from future pollution fines in return. The Financial Times has reported the creditors would inject about £3.35 billion as part of the turnaround plan, including a provision that Thames Water would pay about £750 million in fees if approved. Ofwat, the sector regulator, has been assessing the proposal with a decision anticipated in the summer.

Without a rescue agreement, Thames Water could run out of cash within months and face collapse. The Times reported government intervention stemmed from concerns that the deal would impose an “undue burden” on customers. Environment Secretary Reynolds is expected to address Parliament on Tuesday. The government’s preferred option remains a market-based solution, but officials have signaled they will act if necessary. The temporary nationalisation option on the table is a special administration regime (SAR), designed to keep essential services running under government management.

Thames Water has said a SAR would not solve underlying issues and could delay necessary improvements, increase costs, shift risk and disrupt operations. Spokespeople for the company have reiterated this view in interviews. CKI Holdings, which has pursued Thames Water through acquisition talks, has argued that allowing private investors to restructure or collapse the company could enable fresh bids. CKI’s Andy Hunter, co-managing director, argued that the next owner should be an experienced, credible operator with long-term focus and the resources to fix Thames Water. He noted CKI already owns 75% of Northumbrian Water and urged a capable operator to take charge. Earlier in the year, Thames Water’ s leadership acknowledged the company was extremely stressed and that turning the situation around could take at least a decade.
