CBI Calls for New Public-Private Partnerships to Boost Infrastructure Investment

CBI-backed plan pushes reformed public-private model for UK infrastructure

A new policy report linked to the Confederation of British Industry argues that the UK needs a reformed approach to public-private partnerships. The proposal introduces Infrastructure Investment Partnerships, a model designed to combine private capital with government oversight for major national projects. Importantly, the framework attempts to distance itself from the criticism that surrounded earlier schemes like the Private Finance Initiative.

The report reframes the infrastructure funding debate. According to the Future Governance Forum summary, the central question is no longer whether projects should be public or private. Instead, the question is whether they can be delivered at all under current fiscal constraints. The report states directly that the real choice is often not public or private, but private or nothing.

This matters because the UK faces sustained pressure to upgrade infrastructure while public finances remain tight. Consequently, new financing models are becoming increasingly relevant for businesses that depend on reliable energy networks, transport links, and digital connectivity. For manufacturers, logistics firms, and construction suppliers, delays in infrastructure delivery create operational bottlenecks and increase costs.

What Infrastructure Investment Partnerships propose to change

The report recommends that government adopt Infrastructure Investment Partnerships as a new form of collaboration for large infrastructure schemes. These partnerships would deploy private capital for projects that might otherwise stall. However, the model includes specific safeguards designed to ensure affordability and protect value for money.

The proposal also includes a sub-model called Regeneration IIPs. This variant is designed to maximize the economic and social impact of infrastructure sites. Under this approach, private-sector partners could develop commercial opportunities within government-set parameters. The report argues this structure could reduce the public cost of infrastructure by creating private upside, making projects more attractive to investors while improving taxpayer value.

Notably, the proposal aligns with mission-driven government and industrial strategy. This suggests the model is intended to support strategic priorities rather than simply outsourcing delivery. For businesses involved in supply chains for construction, engineering, or facilities management, this could mean more predictable project pipelines if the model gains traction.

Why governments turn to public-private partnerships despite controversy

The policy logic behind public-private partnerships is well established internationally. The World Bank notes that governments increasingly use these structures because of fiscal constraints and the need to expand infrastructure investment. Research from the United States and California has found that well-structured partnerships can reduce cost overruns and accelerate delivery.

According to the World Bank, partnerships can help governments introduce private sector technology and innovation. They can also improve operational efficiency and incentivize on-time and on-budget delivery. Additionally, they provide budget certainty and transfer long-term value-for-money risks to the private sector.

However, the World Bank also warns that partnerships often involve higher development, bidding, and implementation costs than traditional procurement. Therefore, governments must judge whether the benefits justify the expense. This caution is significant for the UK proposal, which is not simply a call for more privatization but an attempt to design partnerships with stricter safeguards and clearer public benefit.

The Treasury’s 2015 paper on risk-sharing in partnerships emphasized that alternative incentive structures can align sponsor and investor interests. Nevertheless, this only works if contracts are carefully designed. For businesses considering involvement in these partnerships, this means contract terms and risk allocation will be critical to commercial viability.

How earlier UK models shaped the current debate

The proposal explicitly aims to avoid the political and financial criticisms that surrounded earlier schemes in the UK. The Private Finance Initiative, in particular, faced criticism for high costs, inflexibility, and poor value. While the source material does not detail these critiques at length, the report’s emphasis on reform signals an attempt to distance the new model from past shortcomings.

This context matters for businesses evaluating future opportunities. Earlier partnerships often locked public bodies into long-term contracts with limited flexibility. In some cases, maintenance costs escalated beyond initial projections. As a result, any new model will face scrutiny over whether it genuinely addresses these issues or simply rebrands old structures.

The UK government closed the Private Finance Initiative to new projects in 2018. Since then, there has been no equivalent framework for large-scale private investment in public infrastructure. Consequently, this proposal represents a potential reopening of that market, albeit with a different structure and tighter controls.

Fiscal constraints drive the renewed interest in private capital

The UK’s infrastructure investment gap is well documented. Public spending on infrastructure has fluctuated in recent years, and many projects face delays due to budget pressures. Meanwhile, businesses continue to need better transport links, energy networks, and digital infrastructure to remain competitive.

This creates a practical dilemma for government. Major infrastructure projects require substantial upfront capital and deliver benefits over decades. Traditional public procurement depends on government borrowing or taxation, both of which face political and economic limits. Therefore, partnerships that bring in private capital can make some projects financially feasible that would otherwise be deferred indefinitely.

For businesses, this has direct implications. Delayed infrastructure affects operational efficiency, increases logistics costs, and can make UK locations less attractive for investment. Conversely, accelerated delivery of transport, energy, or digital infrastructure can create new business opportunities and improve competitiveness.

Core features of the proposed partnership model

• Infrastructure Investment Partnerships would deploy private capital for large infrastructure schemes while maintaining government oversight and strategic control.
• The model includes safeguards designed to ensure affordability and protect value for money, addressing criticisms of earlier partnership structures.
• Regeneration IIPs would allow private-sector partners to develop commercial opportunities within infrastructure sites, creating additional revenue streams to offset public costs.
• The proposal aligns partnerships with mission-driven government and industrial strategy, suggesting selective use for strategically important projects.
• The report was published in September 2024 by the Future Governance Forum and is associated with the Confederation of British Industry.

What businesses should consider about the proposed model

The proposal raises several questions for businesses that might participate in or be affected by these partnerships. First, contract terms and risk allocation will be critical. Earlier partnerships sometimes left private partners exposed to operational risks they could not fully control, while public bodies faced inflexible contracts that limited their ability to adapt to changing needs.

Second, the emphasis on affordability and value for money suggests tighter cost controls than some earlier models. This could mean lower margins for contractors and operators, but potentially more sustainable long-term relationships. Businesses considering involvement will need to assess whether the risk-reward balance works commercially under the proposed structure.

Third, the alignment with industrial strategy suggests these partnerships will focus on priority sectors. Energy networks, transport infrastructure, and digital connectivity are likely candidates. Therefore, businesses in construction, engineering, facilities management, and related supply chains should monitor which projects are designated for this model.

Finally, the success of the model will depend on whether it can demonstrate genuine public value. If early projects encounter the same criticisms as earlier schemes, political support could evaporate quickly. Consequently, businesses should evaluate not just the immediate commercial opportunity but the long-term viability of the partnership framework.

For businesses that depend on reliable infrastructure, the proposal represents a potential acceleration of delivery timelines. However, it also introduces complexity around procurement, contract structures, and risk allocation. Companies involved in sustainable procurement and supply chain management will need to understand how these partnerships affect tender criteria and compliance requirements.

Commercial implications for manufacturers and construction firms

Manufacturers and construction firms have a direct stake in how infrastructure is financed and delivered. Delayed projects mean lost contracts, idle capacity, and reduced investment in skills and equipment. Conversely, a functioning pipeline of major infrastructure projects provides visibility for workforce planning and capital investment.

The proposed model could create opportunities for firms willing to navigate the partnership structure. However, it also requires careful evaluation of contract terms. Earlier partnerships sometimes included performance penalties that transferred significant risk to contractors. Therefore, firms should assess whether the proposed model offers a fair balance between risk and return.

Additionally, the emphasis on regeneration and commercial development suggests opportunities beyond traditional construction contracts. Firms with expertise in mixed-use development, property management, or facilities services may find new markets opening up if the model allows for commercial activity within infrastructure sites.

For businesses already involved in public sector supply chains, the proposal may also affect procurement processes. If partnerships replace traditional procurement for certain projects, suppliers will need to understand how to engage with private-sector partners rather than directly with government bodies. This could change tender criteria, payment terms, and contractual relationships.

How the proposal fits within broader industrial strategy

The report’s emphasis on alignment with mission-driven government and industrial strategy suggests these partnerships are intended to support broader economic goals. This could mean prioritizing projects that support decarbonization, regional development, or economic resilience.

For businesses, this creates both opportunities and requirements. Projects linked to net-zero targets, for example, may require contractors and operators to demonstrate carbon reduction capabilities. Firms that have invested in carbon reporting and emissions management may find themselves better positioned for these opportunities.

Similarly, projects focused on regional regeneration may include employment and skills requirements. Contractors may need to demonstrate local hiring, apprenticeships, or community engagement as part of their proposals. Consequently, businesses should consider how their social value offering aligns with the likely priorities of these partnerships.

The proposal also reflects a broader shift in infrastructure policy toward more strategic use of private capital. Rather than blanket privatization or purely public delivery, the model suggests selective partnerships for projects where private capital can genuinely add value. This pragmatic approach may indicate how future infrastructure policy evolves across different sectors.

Questions businesses should ask about future partnerships

Several practical questions remain unanswered by the proposal. First, which projects will be designated for the partnership model? Without clarity on project selection criteria, businesses cannot assess the commercial opportunity or plan their involvement.

Second, how will risk be allocated between public and private partners? The proposal emphasizes safeguards and affordability, but the specific contract terms will determine whether the model works commercially for private participants. Businesses should seek clarity on performance requirements, penalty structures, and revenue mechanisms before committing to these partnerships.

Third, how will the model handle changes in scope or requirements over long contract periods? Earlier partnerships were criticized for inflexibility when public needs changed. Therefore, businesses should understand what flexibility is built into the proposed structure.

Fourth, how will the model interact with existing procurement rules and compliance requirements? Public procurement is subject to regulations on competition, transparency, and social value. Partnerships will need to comply with these requirements while also delivering the commercial flexibility that attracts private capital.

Finally, how will success be measured? The proposal emphasizes value for money and public benefit, but the specific metrics will determine whether projects are judged successful. Businesses involved in these partnerships will need to understand how their performance will be assessed and what reporting requirements they will face.

Government and regulatory sources for further information

Businesses seeking more detail on public-private partnerships and infrastructure policy can consult several authoritative sources. The World Bank PPP Knowledge Lab provides international context on the benefits and risks of partnership models. The U.S. Department of the Treasury published research in 2015 on risk-sharing approaches that align sponsor and investor interests.

The Future Governance Forum report provides the most detailed outline of the UK proposal. However, businesses should also monitor announcements from the Department for Business and Trade and HM Treasury for any government response to the recommendations.

For businesses considering involvement in infrastructure partnerships, understanding the regulatory and compliance landscape is essential. The compliance requirements for public sector contracts continue to evolve, and partnerships will likely face scrutiny on environmental, social, and governance criteria alongside financial performance.
