Thames Water’s main lenders are offering the government a “golden share” and more control for local authorities in a bid to stop the troubled supplier from being nationalised.
The government recently rejected a previous rescue proposal, and the understands the lenders are preparing a legal challenge in case the new Andy Burnham-led government takes the firm into public hands.
In his first speech as prime minister on Monday, Burnham said he wanted to see greater public control of “life’s essentials”.
The new proposal offers local authorities greater involvement in the firm, similar to the relationship between United Utilities and Greater Manchester agreed when Burnham was the city’s mayor.
The London & Valley Water (L&VW ) consortium of lenders had already proposed a £10bn deal to prevent Thames Water from entering administration. It would involve writing off nearly half of its debt and injecting new cash in return for leniency on future pollution fines.
The deal was rejected by the government in June, with then-environment secretary Emma Reynolds saying it did not do enough for consumers or the environment.
Sources close to the new deal said the creditors had sweetened it with hundreds of millions in new money on top of the existing offer. A golden share would give the government veto power over decisions.
The government has been contacted for comment.
L&VW said on Tuesday that the new offer had “material improvements” on the old one, and would benefit customers.
A spokesperson said: “We continue to believe that the L&VW plan is by far the fastest and most reliable route to solving Thames Water’s complex problems and improving outcomes for customers and the environment.”
They said the new deal “achieves this without any government funding or cost to taxpayers”.
Fears first emerged three years ago that Thames Water could collapse and it has recently warned it could run out of cash by November.
The company, which supplies water and wastewater services for 16 million people across London and parts of southern England, was handed a £122.7m fine last year, the biggest ever issued by the industry regulator Ofwat, for breaching rules on sewage spills and shareholder payouts.
Sources close to the creditors have previously told the that in the event of full nationalisation, they would pursue payment in full of the outstanding debts as has happened in previous cases, which could leave the government with a multi-billion-pound bill.
If the company does go bust, households will still have drinking water and sewerage services.
