Future of Thames Water

Al Pinkerton Excerpts

Tuesday 6th January 2026 Westminster Hall

[Freddie van Mierlo (Henley and Thame) (LD)]

It is a pleasure to serve under your chairship, Mrs Harris. I thank my hon. Friend the Member for Oxford West and Abingdon (Layla Moran) for securing this debate.

Every week my office is inundated with emails relating to Thames Water. Issues range from miscalculated and aggressive billing to the now ubiquitous sewage discharging into local rivers and streams, and indeed the flooding of homes and gardens with human waste. Members have spoken eloquently on those issues, so, in the interest of time, I will not repeat what they said.

Since being elected I have also been made aware of the issue of tankering in my constituency—in other words, tankers sitting next to overwhelmed pumping stations, ready to take sewage away to a treatment works. It should be a temporary stopgap, perhaps if there has been an unexpected surge in sewage, yet it has become institutionalised. Rather than upgrading pumping stations and stopping groundwater infiltration, which is the source of the problem, the company is taking the easy way out. In the village of Cuxham, my constituents have been forced to tolerate 24/7 tankering for over a decade. Staff have got so comfortable in Cuxham that they have created their own little camp, complete with a Portaloo for their own comfort. It is probably needed, but is nevertheless a sign of just how institutionalised the practice is.

My hon. Friend describes the tankering of sewage from his constituency. In 2023, those tanks arrived in my constituency and the sewage was stored in open tanks on a Thames Water site for an entire summer, casting a stinky pall over the whole of Camberley town centre. It was an environmental crime and Thames Water promised to pay my constituents compensation, which they have never received. Does he agree that we need a far tougher regulator to bear down on these appalling environmental practices?

[Freddie van Mierlo]

I wholeheartedly agree that we need greater regulation. I can only apologise that my hon. Friend has been at the raw end of our tankers.

My staff and I have tried to influence the company to install the measures that are needed, particularly in Cuxham, to resolve the issue, but Thames Water tells us that further investigations are needed and it must do more reports. When we ask when they are going to take place, it tells us, “There’s too much water now because it is winter. We must do them in the summer.” When we get to summer, it tells us, “There’s no water in the pipes, so we’ll have to wait till winter.” It is a ridiculous case that highlights just how short-sighted Thames Water is and how incapable it is of taking a long-term view. It is clear that Thames Water is now in a state of complete, irrecoverable disrepair.

Can the Minister explain why decisive action has not been taken to put Thames Water into special administration? Our constituents have no choice over who supplies their water, and it is down to the Government to protect them from being exploited. I hope that the Minister listens to the experiences of constituents that have been shared today, gains the confidence that a 174-seat majority should give her and takes bold action.
