Castle Water returns with a turnaround plan designed to ensure that money is targeted at solving the company’s pollution crisis

A bidder for Thames Water has returned with an improved offer in an attempt to break the impasse between the crisis-hit utility’s £20 billion debtholders and the industry regulator over how to prevent it falling into insolvency.

John Reynolds, chief executive of Castle Water, said talks between creditors and Ofwat to restructure Thames Water and save it from administration had stalled, possibly irretrievably — however, a spokesman for London & Valley Water, the creditors’ consortium, last night denied this, saying it was “simply not true” that discussions had halted.

Reynolds, a former investment banker and a debt restructuring and turnaround specialist, said he was offering a cash injection of at least £1 billion above current proposals, and backed by the privately-owned property empire of the multibillionaire Pears family.

He said his turnaround plan would ensure that extra money was targeted at solving the pollution crisis at Thames.

“We are confident we can solve the problem,” said Reynolds in his first interview since his initial bid to save Thames Water was rejected in the spring in favour of proposals by KKR, the private equity giant.

KKR subsequently walked away leaving the current situation, in which bondholders standing behind much of Thames’s £20 billion debt are trying to take control.

However, Reynolds believes the creditors’ negotiations with Ofwat, the regulator, have stalled because their proposals will not get Thames back to the investment grade it needs to be viable.

Its financial restructuring plan does not go far enough and does not deal with the company’s environmental crisis, Reynolds said, which credit rating agencies need to see has been dealt with.

“No one wants a restructuring that does not stick. The negotiations are not heading anywhere,” said Reynolds.

“You cannot compromise on the pollution problem. It has to be resolved and that means changing the way the company spends its money.”

Thames Water is the UK’s largest water business, supplying about 16 million people. It is trying to avoid temporary renationalisation. Its financial crisis is combined with a scandal over its poor performance on sewage pollution incidents and infrastructure upgrades.

The proposals of the creditors concede that its operational turnaround plan will continue to allow for serious pollution incidents.

Reynolds disagrees. “There has to be zero tolerance of serious pollution incidents. There has to be investment up front without which you cannot sort it out,” he said of his plans which would target the infamous Mogden sewage works in west London, one of the weakest links in Thames’s wastewater network.

That extra investment, he said, could be freed up by the creditors taking a greater haircut on their liabilities and with an extra injection of equity investment.

Currently the creditors’ consortium London & Valley Water is offering to write off £7.5 billion of existing debt, wiping out junior creditors in their entirety and making £5.4 billion of new money available — £3 billion in an equity injection and the balance in new debt and bank overdrafts.

Reynolds believes that is not enough to solve the pollution crisis. He is offering extra cash from the Pears family in return for operational control of the turnaround plan.

Castle Water is the retail intermediary between Thames Water and local authorities and businesses in the London region.

“We know Thames Water well and its asset base,” said Reynolds of the interaction.

“We would be able to work with the creditor group leaving us with operational control of the business. The creditors group are not specialists in doing an operational turnaround. We have a turnaround team which is ready and available and with the funding to do it.”

Reynolds said “conversations” but not formal talks had happened between him and certain creditors.

His turnaround plan, he said, would also address understaffing and too much outsourcing.

He said he believed the 8,000-strong Thames Water workforce serving a large geography and close to 16 million people, a quarter of the country’s population, was 2,000 too few to be fit for purpose.

And, he said, the failing company needed to move on: “The culture has to be fundamentally changed, a change in the delivery culture. Managers need to be empowered, it needs to encourage responsibility and excellence.”

Reynolds is also holding to his original manifesto that Thames Water should be returned to a stock market listing as soon as practicable to encourage the end of structural opacity which has blighted the company’s accountability. Thames was last listed on the stock market when it was taken over by the German utility RWE in 2001.

London & Valley Water said: “Thames Water needs £5 billion of urgent funding from committed and experienced new investors to deliver improved outcomes for its customers and employees. We are working hard to secure a solution as quickly as possible.

“The London & Valley Water plan will invest £20.5 billion over the next five years to fix the foundations, upgrade the network and reduce pollution so that Thames Water can once again be a reliable, resilient, and responsible company for its 16 million customers.”

A Thames Water spokesman said: “Discussions between Thames Water Utilities Limited’s senior creditors, the London & Valley Water consortium, Ofwat, and other regulators in relation to a potential market-led solution to the recapitalisation of the company are continuing.

“TWUL remains focused on delivering a recapitalisation transaction which delivers for its customers and the environment as soon as practicable.”
