I am very grateful to the noble Baronesses, Lady Neville-Rolfe and Lady Kramer, for their comments and questions, and for their broad support and welcome for this strategy.
The noble Baroness, Lady Neville-Rolfe, began in her non-partisan mode, which I will try to replicate if I can. She talked first about the low rate of investment, and she is absolutely right. When we came into power, we saw the lowest rate of private sector investment as a share of GDP in the G7; we clearly have to turn that around. We saw public sector investment repeatedly cut, which is one of the reasons why we changed the fiscal rules in the way that we did, to incentivise capital investment and try to protect it from being cut to subsidise day-to-day spending. I am very grateful to the noble Baroness for her support for that investment and for the plan that is in front of us.
I am grateful to her for welcoming the maintenance fund. As we speak, there is a £46 billion backlog in the public sector maintenance of our schools, hospitals, prisons and courts. As part of this plan, we are putting £5 billion into the maintenance backlog for the NHS, £3 billion into our schools by 2030, and £600 million into courts and prisons. That is really important, so I am pleased that there is cross-party support for it.
The noble Baroness, Lady Neville-Rolfe, talked about governance and delivery capacity. I completely agree with her on the point about delivering value for money. Obviously, the strategy is not just about giving long-term certainty of investment, in terms of the numbers—she is quite right to say that—but what sits beneath them. The strategy is about trying to do things differently and to make sure that we get the strategic planning behind the investment that we are making.
That is the insight that sits behind the creation of NISTA, the National Infrastructure and Service Transformation Authority. It brings together under one roof infrastructure expertise combined with the policy and strategy insight of the National Infrastructure Commission and the delivery specialism of the Infrastructure and Projects Authority. Every two years, it will do a report into the delivery of this strategy. It will give Ministers real-time advice and expertise on specific projects. I hope that that goes a long way to solving some of the issues that the noble Baroness talked about.
The noble Baroness also talked about where the money is coming from. The announcements, as part of the spending review envelope, were fully funded and fully costed as part of that process and are within the current fiscal envelope. Beyond that, we have said that we will guarantee that investment spending will grow by at least inflation for the period beyond the spending view for a total of 10 years, which gives people certainty about the level of infrastructure investment that we are making.
The noble Baroness, Lady Neville-Rolfe, talked about PPPs, and the noble Baroness, Lady Kramer, also talked extensively about this. I agree with a lot of what she said and respect her great expertise on this matter. She talked about the criteria for success, and lessons clearly need to be learned from our previous experience of PFIs and PPPs. The Government are absolutely committed to that. There are several reports now available to us; the NAO’s lessons learned report, for example, provides vital information on what we can do differently and can do better.
The noble Baroness, Lady Kramer, said that, once you apply those criteria, it severely limits the number of projects for which you can use PPPs. To answer the question from the noble Baroness, Lady Neville-Rolfe, I do not think that this is about huge, widespread use. We clearly want a widespread degree of private sector capital coming in and financing infrastructure, and we want to continue to invest alongside the private sector and the private sector to step up and fund things.
We see a role for PPPs but in a very limited way and where their role will clearly be appropriate. We have said specifically that we will explore the feasibility of using new PPPs—learning lessons and applying the right criteria—for taxpayer-funded projects in very limited circumstances where they could represent value for money. We have given two specific examples where we think they could do that. One good example is Euston—the HS2 station—where we will investigate the use of PPP models for user-funded infrastructure. The other is the Lower Thames Crossing, where, again, we think there is the potential for the criteria that the noble Baroness mentioned to apply. There are a limited number of examples but those are two where there is a clear case to be made.
On housing, I completely agree that 1.5 million new homes is a stretching target. It absolutely remains our commitment and we think we are on course towards achieving it. We put a record amount of funding—the greatest for several generations—into social housing. The noble Baroness is clearly right that the potential occupiers want that housing now, which is why that funding has gone in. She wanted reassurance, and I can say that we firmly believe that we are on course towards that housing target.
Both noble Baronesses talked about skills, and I completely agree. It is good that we are in the spirit of consensus and cross-party thinking here. Obviously, with these commitments, it is absolutely right that we need people to build the things that we want built. Clearly, we can always do more, but we have made a strong start. We have made a record commitment to invest in skills—£1.2 billion of additional investment per year by 2028-29 to support current and future workforce needs.
I know that we are in a cross-party mood, but I have to reflect the fact that the degree of underfunding that we inherited was substantial. We had to put in significant amounts of money—billions of pounds—just to stand still and just to plug the gap that existed between needed provision and the funding that was there. Having to plug that gap limits the extent to which we can move forward.
However, we have provided funding to support over 1.3 million 16 to 19 year-olds to access high-quality training—some 65,000 additional learners per year by 2029. The spending review has delivered £625 million to train up to 60,000 construction workers. In the industrial strategy yesterday, we announced that we will introduce new short courses for priority skills as part of the growth and skills levy, continue to roll out foundation apprenticeships and deliver a targeted package for engineering skills. We have specific packages for engineering and construction, both of which are priority occupations in the infrastructure strategy and the industrial strategy.
How do we choose the investment? We always talk about growth, and I think noble Lords can see that much of this investment is targeted towards the sectors that will, I hope, really drive our growth agenda—transport, energy and housing just to name three.
On the questions about London from the noble Baroness, Lady Kramer, I cannot give any commitments today on the future financing model, but I completely share her support for London and her reflection of it as the golden goose. Future investment in London will be central to driving the economy.
