Overview
The UK is not short of infrastructure ambition.
The Government has set out plans to accelerate housebuilding, strengthen defence capability, modernise transport networks and deliver the energy infrastructure needed to support economic growth and energy security. Yet ambition alone is not enough. The challenge now is turning these plans into action and delivery.
Redefining value in infrastructure delivery
The creation of the National Infrastructure and Service Transformation Authority (NISTA) reinforces the growing consensus that Britain’s infrastructure challenge is now one of delivery rather than ambition. However, delivering projects is only part of the equation. As attention shifts towards execution, a more fundamental question emerges: how should success be measured?
The answer lies in taking a longer-term view of value. In an era of constrained public finances, every investment must demonstrate clear value for taxpayers. Yet value for money should not be confused with selecting the lowest-cost option, instead it should be judged by the long-term benefits infrastructure delivers.
Infrastructure assets often operate for decades, meaning decisions made during planning and procurement can continue to influence resilience, operational performance and maintenance costs long after construction has finished. The question, therefore, should not be how cheaply an asset can be built today, but how effectively it will perform over its lifetime. Analysis from the Productivity Institute identified weak strategic direction, consenting challenges and delivery constraints among the factors driving higher costs and poorer outcomes across major projects. The evidence suggests that long-term outcomes are shaped just as much by decisions made before and after construction as they are by the build itself.
Across highways, transport networks, public estates and defence infrastructure, many of the greatest opportunities to improve outcomes emerge after construction through better asset management, maintenance planning and operational decision-making. This is where Amey’s end-to-end expertise is particularly valuable, combining delivery, operations and maintenance experience to help clients maximise performance throughout an asset’s lifecycle. A whole-life approach to infrastructure delivery is therefore essential if public investment is to generate lasting value. This also requires continuity of accountability, ensuring responsibility for delivering value extends from design and construction through to operations and maintenance.
Infrastructure delivery is now a growth issue
Transport, energy and defence infrastructure all underpin economic growth and national resilience. What’s more, the greatest challenge here is not making the case for investment, but delivering projects quickly enough to realise their benefits.
The economic case for transport investment is well understood. Better connectivity supports labour mobility, unlocks housing, attracts investment and improves productivity. Yet, when projects are delayed, not only do delivery costs inevitably rise, but the economic opportunities they are expected to create are also delayed. The same principle applies to energy infrastructure. Whether the priority is strengthening energy security, supporting industrial growth or enabling electrification, Britain’s future competitiveness depends on its ability to deliver infrastructure at pace. Delays will likely postpone investment decisions and further constrain economic activity. Defence infrastructure is equally important. As defence spending increases, delivering bases, accommodation, logistics hubs and training facilities well will become increasingly critical. You simply cannot have operational readiness without infrastructure readiness.
One of the defining features of modern infrastructure is how interconnected it has become. Transport, energy, housing and defence are no longer separate challenges to be solved independently. They increasingly rely on one another to deliver economic growth and national resilience. As a result, delays in one part of the system can create a ripple effect across many others.
Improving infrastructure delivery is not always about increasing capacity or building more. It is also about making better use of the assets already in place. Digital technologies, asset intelligence and predictive maintenance are enabling infrastructure owners to make smarter investment decisions, improve performance and extend asset life. At Amey, we see this first-hand through our work managing and maintaining critical infrastructure, where better use of operational data is helping clients improve reliability, reduce whole-life costs and maximise value from existing assets. As pressures on public finances and network capacity continue to grow, Britain’s ability to drive productivity and support economic growth will depend as much on how effectively it manages existing infrastructure as on building new projects.
Local leadership builds national growth
The delivery challenge becomes even more important as power is increasingly devolved to regional and local leaders. Across England, mayors and combined authorities are taking control of major transport, regeneration and economic development programmes, placing them at the heart of the Government’s growth agenda. This presents a significant opportunity. Local leaders are often best placed to understand the needs of their economies, communities and businesses, enabling them to make investment decisions that reflect local priorities and unlock growth. Yet devolution alone will not deliver growth. If local leaders are expected to unlock investment and transform local economies, they need more than responsibility. They need the certainty, powers and capability to act. Long-term funding, stronger local delivery capacity, and clearer accountability frameworks will be critical to turning devolved powers into visible economic outcomes.
Behind every infrastructure project are the people who make it happen. One of the greatest risks to Britain’s infrastructure ambitions is not a lack of projects or funding, but the capacity to deliver them. Engineers, technical experts, project managers, asset managers, and skilled trades will be every bit as important as the investment that supports them. A recent annual report from Skills England highlights the growing demand for engineering, technical and construction skills across sectors critical to the UK’s future economy. Building a stronger skills pipeline should therefore be viewed as an economic need in its own right. As such, industry has a key role to play in this. In 2025, Amey supported more than 450 apprentices, graduates and placement students, and delivered over 30,000 apprenticeship weeks. Initiatives like these will need to be replicated at scale if Britain is to develop the workforce required to deliver its long-term ambitions.
Measuring success through outcomes and resilience
Infrastructure must increasingly be viewed through the lens of resilience as well as growth. Transport networks, defence estates, energy systems and public assets go beyond power economic activity as they also strengthen national resilience. As recent years have shown, reliable infrastructure is critical in responding to climate pressures, geopolitical uncertainty and economic shocks. The most successful investments will therefore be those that deliver both economic growth and long-term resilience.
This will ultimately drive the shift in how infrastructure is managed. Data-led asset intelligence, predictive maintenance, and smarter operational planning are helping organisations identify risks earlier, target investment more effectively and improve network performance. In an era of constrained public finances, resilience is not just about strengthening infrastructure. It is about ensuring every pound invested delivers maximum value. Ultimately, success should not be measured by the size of a funding announcement or the scale of a capital programme. It should be geared towards achieving measurable outcomes. Are journeys faster? Is energy more secure? Are communities better connected? Are businesses more productive? Are public services more resilient? These are the metrics that matter.
Britain has no shortage of vision. The projects are known, the investment priorities are understood and the economic case for infrastructure is clear.
Delivering meaningful outcomes is now within reach, but it requires a different mindset. Success should not be measured by the value of funding announcements or the number of projects approved, but by the impact infrastructure creates for people, places and the wider economy.
Achieving that will require closer collaboration between policymakers, local leaders, infrastructure owners, operators and industry partners. At Amey, we are committed to playing our part by combining delivery expertise, asset intelligence and long-term stewardship to help turn infrastructure ambition into lasting impact.
