Future of Thames Water

Helen Maguire Excerpts

Tuesday 6th January 2026 Westminster Hall

[Charlie Maynard (Witney) (LD)]

It is a pleasure to serve under your chairship, Mrs Harris. West Oxfordshire is very much ground zero for Thames Water. We have the Thames itself, the Evenlode and the Windrush. West Oxfordshire district council has done great work in going after Thames Water. We have WASP—Windrush Against Sewage Pollution—and we, as a team, have also gone after Thames Water through the High Court and the Court of Appeal, all the way up to the Supreme Court. I thank the legal team that fought pro bono with us last year on behalf of the 16 million Thames Water customers who are being royally stiffed.

As my hon. Friend the Member for Oxford West and Abingdon (Layla Moran) mentioned, the bills people are paying are completely outrageous. I have had constituents whose bills have gone up by 50% and 70%. Somebody got a 93% increase through the post. It is outrageous.

[Helen Maguire (Epsom and Ewell) (LD)]

One of my local residents has had their bills doubled, and a mains water pipe in West Hill has burst, causing major chaos for my constituents. Yet £2.5 million was given out in executive bonuses last April. It is disgraceful that the Labour Government have left our constituents to foot the bill for Thames Water’s shoddy performance. Does my hon. Friend agree that we should put the company into special administration?

[Charlie Maynard]

I completely agree—well said. What is so depressing is that the Labour Government have embraced the Conservative’s mistakes over Thames Water, and our water sector more broadly, and then doubled down on them. The Government have been and continue to be hoodwinked by a bunch of hedge-funds whispering about financial Armageddon into ears of the Department for Environment Food and Rural Affairs and Ofwat. They need to follow through on their regulatory obligations, because we need regulators that have teeth and backbone and will actually deliver. Instead, we have hedge-funds making vast fees with outrageous interest expenses, at the cost of us as consumers. It is not fair. It is a great shame, and it is also unnecessary, because the company’s financial and environmental positions are completely unsustainable. With every day that passes, this becomes more Labour’s problem.

We now need to cut the rope and put the company into special administration, on account of its many breaches of its licence obligations, so that its debt can be written down to around three times cash flow and it can come out of the special administration regime mutually owned by 16 million customers, and run on behalf of them and the environment, and with Government-guaranteed funding mechanisms in place to fund the investment required over the next three, five and 15 years.

Will the Government please answer my letter to the Minister responsible for sewage and flooding, sent at the start of October? I asked whether the Minister believes that Thames Water’s ad hoc group of class A creditors now exerts material influence over it, thereby meeting the “ultimate controller” criteria. I would really like an answer on that. Last February, a High Court judge found that they have material influence over the company, and it would be great to have a straight answer from the Secretary of State or the Minister on that point.

I would not like the Government to give Thames Water, or any other water company, a free pass on paying environmental fines in full. When there are breaches, we need regulators that enforce the fines that are in place. Similarly, given the extreme precarity of the company’s finances, as my hon. Friends have mentioned, the Government should not entrust it with delivering a huge and costly infrastructure project in Oxfordshire in the form of the south-east strategic reservoir option, about which my hon. Friends the Members for Didcot and Wantage (Olly Glover) and for Oxford West and Abingdon spoke in detail. Given all our constituents’ low level of faith in Thames Water, the future of which is precarious, to put it extremely mildly, it is no wonder that this is causing such alarm to residents in my constituency and those of my hon. Friends.

Please do not be bamboozled by the hedge funds; instead, show some backbone—and do not own the Tories’ mistakes. That is the key thing, because this Government still have a chance to leave it with them. Please do so and put the company into a special administration regime.
