Thames Water creditors offer government 'golden share' in final bid to avoid nationalisation
Creditors of Thames Water have offered the government a 'golden share' in the troubled utility company as part of a last-ditch effort to prevent nationalisation.
The London & Valley Water consortium, which holds approximately £17 billion of the company's debt, proposed giving ministers veto rights over key decisions through enhanced local oversight. The group includes major investment firms Apollo Global Management, Elliott Management, BlackRock, Silver Point Capital and Invesco.
Prime Minister Andy Burnham has argued that public ownership represents the best solution for the water supplier, which serves 16 million customers across London and the South East but is straining under debt that reached £19.77 billion in the year ending March 31, 2026, up from £17.73 billion the previous year.
The consortium said it 'recognises that the new Government would like to see water companies create greater local public control and involvement to strengthen accountability for protecting investment and delivering improvements'. Under the proposal, a supervisory body with enhanced local representation from councils and regional leaders would be established, potentially giving London Mayor Sadiq Khan an oversight role.
Details of the rescue plan
The creditors' proposal involves writing off approximately £9.4 billion to £9.6 billion of Thames Water's existing debt while injecting £3.35 billion in new equity. The consortium has also proposed a £10 billion investment injection in return for new fines over sewage leaks being waived for four years.
However, Environment Secretary Emma Reynolds warned in June that the creditors' rescue plan did not go far enough to protect customers or the environment, delivering a blow to hopes of avoiding nationalisation. The company has also said it has sufficient funding only until October 2026, adding urgency to the negotiations.
Thames Water yesterday imposed a hosepipe ban on 10 million customers, which came into effect at 12.01am on July 23, following three record-breaking heatwaves and the driest spring in years. Water demand has surged to 10 per cent above normal in the Thames Valley and 7 per cent above normal in London.
Financial turnaround amid crisis
Despite mounting debt, Thames Water reported a pre-tax profit of £226.4 million for the year to March 31, 2026, a dramatic turnaround from losses of £1.65 billion the previous year. The debt increase reflected continued drawdowns to fund capital investment in the company's ageing infrastructure.
The consortium has also engaged Pallas Partners, an elite litigation and disputes firm, to prepare for potential legal action against the government if Thames Water is forcibly nationalised and their rescue proposal rejected.
A spokesman for London & Valley Water said:
Thames Water is a company of national importance and we look forward to working with the new Government to secure a long-term solution. We continue to believe that the L&W plan is by far the fastest and most reliable route to solving Thames Water's complex problems.
The proposal mirrors mechanisms used in other privatised companies of national importance. The government holds golden shares in several such firms, including Royal Mail following its takeover by EP Group in 2025. These special shares give the Secretary of State power to veto major asset sales, foreign takeovers or changes to a company's constitution.
Under the creditors' plan, customers would have strong protections, regulators and government would have enhanced oversight, and greater controls would ensure Thames Water delivers the record investment needed to improve environmental and operational performance, the spokesman added.
