Thames Water downgraded further into 'junk' status

The agencies have both cut their ratings for the water company after it said much of its day-to-day funding will run out in December, with further cash access dependent on getting permission from its creditors.

Moody’s downgraded Thames Water to a Caa1 rating, down from a Ba3-PD. The drop signifies that it is a very high-risk company, and is likely to default on its debts.

The ratings firm said the cut “reflects a significantly tighter liquidity position than previously expected”.

S&P, meanwhile, lowered its rating on Thames Water’s class A debt to CCC+, which indicates a similar verdict on the company.

The agency wrote that it is likely the water firm “will default in the next 12 months without any material positive developments”.

The moves come after the utility giant said it will kick off the process of raising more money from investors over the next few weeks.

Thames Water, which serves about 16 million people, faces a funding crisis, with only enough cash to continue operating until May 2025.

It also has more than £15 billion of debt, and regulator Ofwat has said it intends to appoint an independent monitor to supervise the company as it attempts a turnaround.

If Thames Water does not raise fresh cash, it faces a potential nationalisation next year, something the Labour Government has said it is keen to avoid.

The group, which includes large asset managers, hedge funds and pension funds, is also understood to be drawing up a plan to keep the company afloat.

A Thames Water spokesperson said: “We continue to operate to the undertakings agreed with our regulator in July 2024 following the reduction in our Class A debt rating to sub-investment grade and we continue to engage with creditors to consider options for the extension of our liquidity runway.”

Bosses at Thames Water have been scrambling to secure a major cash injection to keep it afloat, and have held talks with both existing shareholders and outside investors.

Sarah Bentley, Thames Water’s previous chief executive, has previously said the firm had been “hollowed out” by “decades of underinvestment”.

It comes after a water industry body warned that Ofwat’s plans to cap water bills could create a “material risk” that suppliers may fail to raise enough cash to invest in stopping sewage leaks.
