At Interchange 26, Amey convened a Chatham House roundtable bringing together senior leaders from across infrastructure, transport, energy and the public sector to explore a pressing question: how can the UK deliver infrastructure with greater certainty in an increasingly complex environment?
Held under the Chatham House Rule to encourage open and candid debate, the discussion revealed a clear consensus that the UK’s infrastructure challenges are not rooted in a lack of technology, capability, capacity or capital. Instead, against a backdrop of rising energy demand, climate resilience pressures and population growth, participants pointed to systemic barriers as the greatest obstacle to delivering the resilient, connected infrastructure the UK needs.
Big ambition, fragmented delivery
The discussion opened with a challenge to one of the most common assumptions in infrastructure delivery: that the UK’s difficulties stem from a lack of ambition, investment or innovation. Instead, participants argued that the greater challenge lies in coordinating delivery across a fragmented system. As one participant reflected, “the issue is not ambition, it is how we coordinate delivery across a system that remains fragmented.” The challenge lies in planning and coordination across sectors, timescales and delivery. Fragmentation is not only inefficient, but it can undermine system resilience by preventing infrastructure from functioning as a cohesive whole.
Transport, energy and placemaking are now part of the same planning problem. Decisions in one area directly constrain or enable outcomes in the others, yet decision-making remains split across departments, funding pots and regulatory bodies. One of the roundtable participants highlighted this issue as, “people do not experience infrastructure in sectors or as part of separate entities, they experience it as a place, and that’s where our approach still falls short.” This disconnect is most visible not in strategy, but in delivery. Grid connections lag behind demand, streets are repeatedly disrupted by uncoordinated works, and transport investment does not always unlock its intended economic or social benefits. The consequence is inefficiency, higher costs and growing public frustration – not because communities oppose progress, but because delivery feels disjointed, disruptive and hard to justify.
Political timescales are colliding with infrastructure reality
Another dominant theme was the persistent mismatch between political cycles and infrastructure lifecycles. While major infrastructure investment typically requires 10–20 years of certainty to plan, finance and deliver effectively, strategy has historically been shaped by shorter electoral cycles, with shifting priorities between administrations. As one participant noted, “we talk about long-term infrastructure, but the political system we’re asking to deliver it through is still operating on short-term incentives.” Although the UK’s recently published 10-year Infrastructure Strategy represents a positive step towards setting a longer-term direction, the roundtable highlighted a continued gap in how this intent translates into consistent regional and local planning, funding decisions and delivery pipelines. In practice, this lack of alignment introduces uncertainty at critical points in the delivery chain. As another participant reflected, “it is not the vision that makes projects hard to back for local communities, it is the uncertainty about whether that vision will come to fruition. This has really disenfranchised many people.” The result is not only slower progress, but a more constrained environment for investment and delivery, where decisions are shaped by short-term thinking that makes it harder to plan, fund and build resilience over time.
What is needed is greater consistency around the fundamentals which means clearer long-term objectives, stronger cross-party alignment on infrastructure investment, and improved certainty for major projects that extend beyond political cycles. As one participant stated, “resilience isn’t something you can retrofit later; it has to be designed into the way projects are planned and funded from the outset.”
Changes to the Treasury’s Green Book will also help support a more effective approach to valuing projects and investment decisions. However, the roundtable made clear that creating the conditions for proactive investment in communities requires more than appraisal reform alone. It depends on clearer long-term pipelines that provide visibility and confidence to investors and service providers as well as more flexible funding models such as private-public financing that can support tangible outcomes rather than just providing lowest-cost solutions, and stronger alignment between national priorities and local delivery.
People experience places, not policy frameworks
A consistent theme throughout the discussion was people. At the heart of every infrastructure system are the communities it serves. People do not interact with departments or funding streams – they interact with places. What matters to them most is whether they can travel reliably, charge their vehicles, access healthcare, and connect to opportunities.
When delivery falls short, it is often because projects are scoped too narrowly, engagement happens too late, and benefits are communicated in ways that do not align with lived experience. This is particularly true for investments whose value is system-wide rather than immediately visible, such as freight, resilience, capacity and the ability of systems to perform consistently under pressure.
When the narrative is unclear, opposition often follows. This was highlighted by one of the participants pointing out; “opposition isn’t usually geared towards the infrastructure scheme itself, it’s to the disruption it can cause when people don’t understand what it’s for.” Rather than reflecting resistance to progress, this often points to a lack of clear, early engagement on the purpose of schemes and the outcomes they are intended to deliver. What is needed is a more people-centric approach to communication. This does not necessarily mean overpromising but rather, being clear from the outset about why infrastructure is needed, what will change, what disruption is expected, and how benefits will be realised in terms people recognise such as time, cost, reliability, safety and local benefits. Framing resilience in terms of fewer disruptions, faster recovery and more dependable services also helps make it tangible and meaningful. As one participant noted, “people are far more engaged when they can see what it means for them in practice not in abstract policy terms, so you have to rethink your engagement strategy.”
Effective engagement should therefore focus on linking infrastructure decisions to lived outcomes, to clearly set out why interventions are needed, what disruptions are likely to occur, how long they will last, and what will improve as a result. When this is done well, resilience shifts from an abstract concept to something communities can understand, evaluate and support.
Reframing infrastructure around outcomes
Framing resilience in terms of fewer disruptions, faster recovery and more dependable services also helps make it tangible and meaningful. “Resilience lands well when people can see what it changes day to day, whether that’s fewer delays, quicker journeys or more reliable services” was noted in the discussion. In practice, this means linking investment directly to outcomes that communities recognise such as better connectivity, reduced journey times, fewer unplanned closures or improved service reliability, rather than abstract resilience metrics. Participants highlighted that where this approach is adopted and implemented, it provides a clearer basis for engagement, helping people to understand both the benefits of investment and any potential trade-offs involved.
A consistent approach to engagement therefore focuses on connecting infrastructure decisions to lived experience. Framing success around clear societal outcomes supports genuine systems thinking, breaks down silos, aligns incentives and strengthens accountability. In practice, participants pointed to outcome-based models where performance is measured against user experience rather than individual assets, allowing resilience to be designed in from the outset as a core requirement rather than treated as a secondary or compliance-driven consideration.
Designing a system that can deliver
Despite the challenges, there was strong alignment on what progress requires. Participants emphasised the need to move beyond siloed planning towards genuinely integrated system design, to bring together energy, transport, digital and place from the outset. This was reflected in the discussion with on participant highlighting; “if you’re planning in silos, you’re already hardwiring fragmentation into your delivery programmes.” Therefore, there is a need to align decisions across sectors early, so that interdependencies are addressed upfront rather than retrospectively. Where this happens, investment is better able to unlock wider outcomes, reduce delivery friction and improve system resilience by managing risks across the whole network rather than within individual assets.
There was also clear consensus on the importance of long-term certainty. “You cannot build capability or attract capital against a pipeline that isn’t stable,” as one participant put it. Providing consistent, long-term direction enables investment decisions, supports the development of delivery capacity and allows resilience to be embedded over time rather than retrofitted.
Communication was identified as a critical enabler of delivery. Participants emphasised that public acceptance depends on clearly linking investment to outcomes people recognise. As one participant put it, “people will accept disruption if they understand what it delivers but too often that link isn’t made clearly enough.” Grounding engagement in real-world impacts, timelines, reliability, cost and opportunity, will help to build much needed trust and strengthens the case for change.
Finally, there was strong support for clearer, system-level accountability. “If everyone owns a piece, no one really owns the outcome,” as one participant observed. Establishing a coordinating leadership function can help align organisations, funding streams and regulatory processes which helps to reduce duplication, accelerating delivery and ensuring the system remains focused on shared outcomes. When brought together, these insights point to a more fundamental shift, from delivering individual projects to designing systems that can deliver consistently, at pace and in ways that communities recognise and value. This requires purposeful leadership to coordinate across the project lifecycle from strategy through to delivery so that infrastructure supports growth, enables net zero and improves public services in a place-based way.
Above all, it requires resilience to be treated as a core design principle that ensures infrastructure is efficient, adaptable, resilient and able to perform in an increasingly uncertain future.
