Thames Water: Government Support

Debate between Luke Taylor and Charlie Maynard

Thursday 3rd April 2025 Westminster Hall

[Charlie Maynard (Witney) (LD)]

It is a pleasure to serve under your chairmanship, Ms Lewell. I thank my hon. Friend the Member for Sutton and Cheam (Luke Taylor) for securing this debate on Government support for Thames Water. What does Government support for Thames Water look like? Our current Government support Thames Water by letting it breach the terms of its operating licence, letting Ofwat ignore its own rules, letting consumers take the pain of higher bills for no gain, letting financiers make out like bandits and letting our rivers continue to be filled with sewage. What is shocking about that is that a Labour Government are doing it. This Government are turning out to be every bit as bad as the Conservatives were at protecting our rivers. They are completely ducking their responsibilities. It is within the Minister’s powers to take action: she is the Parliamentary Under-Secretary of State for Water and Flooding at DEFRA, DEFRA oversees Ofwat, and Ofwat issues operating licences to water companies.

Here are some of the key requirements that Thames Water needs to comply with, per its Ofwat-issued operating licence. First, there is an operational requirement to comply with environmental and health standards. Thames Water is failing that requirement. As per Environment Agency data, and as my hon. Friend the Member for Twickenham (Munira Wilson) said, in 2024 Thames Water discharged nearly 300,000 hours of sewage, which is 50% up on 2023. It is illegal to dump sewage in dry conditions, but it is happening repeatedly. Professor Peter Hammond, who lives in my constituency, monitored the Stanton Harcourt sewage treatment works in my constituency, and found that there had been 266 illegal spills in just a single sewage treatment works in a four- year period. That is a complete failure of that operating requirement.

Secondly, Thames Water is failing the financial viability requirement, under which it is required to have two licences of investment-grade credit ratings. Currently, it has no credit ratings that are investment grade. Standard & Poor’s has the company’s debt 12 notches below investment grade, and Moody’s has it nine notches below. That is as far deep into junk bond territory as one can get. In the last financial year to March 2024, Thames Water had £19 billion of debt but only £1.2 billion of cash in. Everybody knows that that is not a sensible way to run a company.

By allowing Thames Water to breach that rule, we introduce moral hazard into the water sector and all other regulated sectors. Other water companies take note that there has been no material sanction of Thames Water and realise that they can also likely get away with it. Of the nearly £1.4 billion of funding due to come into the company, £900 million is going straight out in interest expenses, sweet financial goodies for hedge funds, and advisory fees. That is not fair on our bill payers. Customers are being royally stuffed, and Ofwat and the Minister’s DEFRA team are standing by.

Thirdly, there is a requirement to demonstrate fairness, transparency and affordability to customers—the fair pricing requirement—and Thames Water is failing at that too. Bills have gone up by a headline of 31%. Many Witney constituents have written to me with increases of 50% and 70%—in one case, it was even 93%. On top of that, to add insult to injury, Thames Water has an application to the Competition and Markets Authority to increase bills even higher, by 59%.

Fourthly, there is the ownership requirement. This one really gets my goat. Thames Water must inform Ofwat of any change to control. Ultimate controllers are defined in Ofwat’s papers as being

“in a position to control or in a position to materially influence the company”.

Thames Water’s own advisers have publicly stated that the company is de facto controlled by its creditors. Ofwat is ignoring this. Extraordinarily, Ofwat, wrote to me in the last month to say that, despite it being publicly stated in the press that Omers, a shareholder in Thames Water, had written its stake down to zero and pulled its board representation off last May, it is still actually controlling the company. Why is this going on? What could be going on here? It smells—

[Luke Taylor]

It smells like—

[Charlie Maynard]

Yes, it does. I think Ofwat is doing exactly what the company’s creditors want it to do, and I wonder why that is happening, because it should not be.

Finally, there is a failure to innovate. There are a host of technologies out there, and far too often we hear the same old lines about Victorian sewers, cameras and how impossible it all is. There is a huge range of leak detection, pipeline monitoring, protective maintenance, trenchless pipe repair and pressure management technologies. I hear from Oxfordshire firms that it is easier to sell sewer technology solutions into the US and Europe than into the UK, so something is going seriously wrong. We could start by looking at whether the incentives are effectively aligned; I do not believe they are.

What are the consequences of this failure to act? It is easy to lay a lot of the blame at the last Government, but the Water (Special Measures) Act 2025 was more window dressing than action. I am new to Parliament, but I was particularly dismayed that not a single word of a single proposed amendment from any party was accepted by the Minister. I wish that in Parliament we all had enough confidence to accept good ideas where we found them—I live in hope.
