Planning and Infrastructure Bill

Debate between Baroness Grender and Lord Lansley

Committee stage
Thursday 24th July 2025 Lords Chamber

[Baroness Grender (LD)]

My Lords, as we consider the challenge of water security, we all feel the urgency. Demand is rising, our climate is changing and not a single new major reservoir has been completed in over three decades, as we have already heard. Yet pursuing a one-size-fits-all solution rarely serves us well, especially regarding water storage and distribution. I particularly thank the noble Lords, Lord Gascoigne and Lord Lucas, for inspiring this discussion and debate.

There is consensus on building new reservoirs, but this cannot be done in isolation. Proper investment from water companies is essential, particularly in tackling leaks and improving demand management so that we use water more wisely, even as we boost supply. This is not either/or; it must be both. Yesterday, in the Statement regarding the Independent Water Commission, the full implication of the broken infrastructure that has led to so much water going to waste was laid down very clearly.

It is tempting to focus on grand, large-scale projects, but we should make space for smaller, locally led interventions that reflect the needs and fabric of our communities. Alongside ambitious infrastructure, a programme of carefully sited small and medium reservoirs, delivered in partnership with farmers, landowners and councils, can speed up progress, reduce environmental barriers and, most importantly, engage local people. We have heard not just from experts but from communities themselves that local schemes such as Slow the Flow projects, natural dams and catchment-based storage bring added benefit for flood mitigation and biodiversity, not just water supply. These nature-friendly solutions must be championed alongside larger reservoirs.

However local schemes alone are not enough. We must pair them with strategic national thinking. Regions with water surpluses should be able to support those facing deficit—a modern, integrated network for water transfer. I ask noble Lords to bear with me, because this is a little complicated. The National Infrastructure Commission, which was replaced by the National Infrastructure and Service Transformation Authority in April 2025, was praised by the National Audit Office for its proposals, which constituted a positive cost-benefit case for establishing a network of strategic transfers of water—a transfer system that enables us to balance supply across the country, smoothing out regional disparities and providing resilience against drought and flooding. The recent Commons Library briefing, Future Water Resources, highlights several proposed intercompany transfers, such as Thames Water to Southern Water—120 megalitres a day—demonstrating that active steps can be and are already being undertaken. Alongside large and small reservoirs, these transfer schemes are truly integral to future-proofing our water supply and reducing the risk of shortages.

Turning to the amendments before us, Amendment 59, in the name of the noble Baroness, Lady Coffey, proposes removing the size and complexity test for new water infrastructure to focus solely on the value for money test. But, as Ofwat’s current regulations set out, that test ensures that projects do not threaten a water company’s fundamental service to customers. Given the sector’s current state, we should tread carefully before removing this safeguard. A more prudent path may be to consider government co-funding models, such as that now being used for nuclear, if projects exceed what companies can realistically deliver and are in jeopardy of providing a poor or totally broken service—or further broken, should I say—to consumers.

Amendment 61, in the name of the noble Lord, Lord Lucas, would hand powers to the Secretary of State to dictate timelines and, crucially, permit bypassing planning controls. While there is much in the amendment that we read with interest, I worry in particular about proposed new subsection (3)(b), which is a significant centralisation of power. Yes, there has been an unacceptable delay in reservoir construction, but concentrating such powers is unlikely to foster better outcomes. Proper local engagement, as we all made very clear in our Second Reading speeches, and scrutiny need to be balanced and are vital partners to each other.

Amendment 62, tabled by the noble Baroness, Lady McIntosh of Pickering, aligns more closely with the objectives on these Benches. I look forward to hearing the Minister’s response to the compelling arguments that were made on the noble Baroness’s behalf.

Above all, we must ensure that interventions, whether mighty reservoirs or smaller, community-scale schemes, work for people and for nature, and are delivered with transparency, accountability and genuine urgency. I hope the Minister will clarify the Government’s support for small reservoirs and for a robust water transfer network, so that every region and every customer in every region can feel protected, valued and heard.

[Lord Lansley (Con)]

My Lords, I intervene in this group to flag up a couple of points. I thank my noble friend Lord Gascoigne for introducing Amendment 59, which makes an interesting point.

In response to the noble Baroness, Lady Grender, the size and complexity threshold test is about assessing whether an infrastructure project is of such size or complexity that the water undertaking cannot manage it or, if it attempts to manage it, it might prejudice its financial ability to meet its obligations to customers. Actually, under current circumstances, we have reached the point where many water undertakers may not have the capacity to undertake infrastructure projects in the way we expected in the past. We know that there was a substantial period when they did manage investment and they increased investment in the water industry, but in more recent years they have not done so and there is considerable risk to their ability to undertake the infrastructure projects we are looking for.

We should not be surprised that that is the case. Take Anglian Water, which is not among the most prejudiced of the water companies at the moment. I was very interested to attend a presentation about Anglian Water’s proposals for the Fens reservoir. It was fascinating, positive and optimistic. Then, in response to a question, Anglian Water mentioned that it is not going to own it. Somebody else will own it, and we do not know who.

So we have to be aware that there is substantial uncertainty about how we will fund much of this infrastructure, but the most important thing was mentioned by my noble friend Lord Gascoigne in moving Amendment 59. The amendment is about which projects should go out to competitive tender. That is all it really tells us. The answer ought to be: if it will secure value for money—indeed, if there is potential for independent financing which, as he said, can be more cost-effectively delivered, and we know that the risk premium on the water undertakings themselves is making their borrowing more expensive than what may well be available through other sources of financing —then we should go down that path. The size and complexity threshold test is unhelpful, gets in the way and creates serious impediments to getting on with infrastructure projects.

Of course, the amendment is not deliverable. It does not deliver the objective in its own right. One would have to substantially change Section 36 and other sections of the Water Act 1991 to achieve the objective, because the regulation derives its power from the primary legislation. We need to look at the Water Act 1991 in substance to achieve that on Report.

What my noble friend Lord Lucas’s amendment says is helpful. When one looks at what it is that governs the delivery of reservoirs, as far as I can tell the Reservoirs Act 1975 basically says that it ought to be done by an appropriately approved construction engineer. That is pretty much it. There is a great deal that should be added to what is required in order to secure reservoir development.

I have two other points to make. The first is that Amendment 62 from the noble Baroness, Lady McIntosh, raises a more significant point than the amendment itself says. We are aiming to secure what we need in terms of water supply. I remind noble Lords of my interests in the Cambridgeshire Development Forum and the Oxfordshire Development Forum, which of course means that two reservoirs—the Fens reservoir and the Lincolnshire reservoir—are relevant, as well as the Grand Union Canal project and related activity to try to supply the east of England. We are in a position at the moment where, by 2050, we will have a deficit in water supply equivalent to a third of our present use. That is the degree of stress that we are looking at and therefore need demand management to be substantially improved and the supply to be improved.
