Reservoirs: Protection from Contamination

Baroness Grender Excerpts

Tuesday 3rd June 2025 Lords Chamber

[Baroness Hayman of Ullock (Lab)]

I can assure the noble Lord that we discuss these matters with the Home Office. As I said, much of what we need to do is across government—one thing that we have been trying hard to do in Defra and other departments since we came into government is to work better across government; that is an important point to make. The noble Lord asked an interesting question about police responses, which I am happy to mention next time I have a meeting with the Home Office to see whether I can get a better understanding about that.

[Baroness Grender (LD)]

My Lords, given Thames Water’s inability to secure private investment with its £20 billion debt burden, can the Minister confirm that, should it have to go into special administration, contingency plans include ring-fenced funding for critical security upgrades at its reservoirs? Specifically, will the Government commit to independent audits of cyber defences and physical protections during any transitional period, which has been highlighted as a period of vulnerability that might be exploited by hostile actors?

[Baroness Hayman of Ullock (Lab)]

The main point is that our water supply absolutely has to be secure. We have to know that we are doing everything we can to protect it from hostile actors, as the noble Baroness and my noble friend mentioned. That is why the cross- departmental work is so important. On Thames Water, I assume the noble Baroness refers to the fact that the preferred bidder has now pulled out. Thames Water has assured us that there are other potential bidders. We need to look at the current situation and, clearly, any investment needs to include security. The PR24 investment that has been made includes a substantial sum for improving security as well as infrastructure. It is important to make the point that it is part of our ongoing discussions with water companies.
