The government’s latest update to the UK Infrastructure Pipeline is sending a clear signal to the rail sector: the scale of future infrastructure investment will demand significant workforce growth, stronger supply chains and more confident long-term planning.
Published by the National Infrastructure and Service Transformation Authority (NISTA), the updated pipeline outlines 734 projects representing £718 billion of public and private investment over the next decade. While the programme spans sectors including energy, health and education, the message for rail businesses is unmistakable. The industry will need to prepare now for the scale of delivery that lies ahead.
For rail contractors, consultancies, technology suppliers and manufacturers, the newly added workforce and skills analysis could prove particularly valuable. For the first time, the Pipeline includes detailed estimates of the labour required to deliver the government’s infrastructure ambitions, broken down by sector and region.
The figures are substantial. Delivering projects in the Pipeline will require an average construction and infrastructure workforce of between 629,000 and 706,000 over the next five years, with slightly lower demand projected in the immediate term. Construction roles account for more than two-thirds of the requirement.
For rail companies already navigating skills shortages across engineering, project management and digital systems, the data reinforces a growing reality: future rail investment will only be deliverable if industry expands capacity and develops the next generation of skilled workers.
Greater visibility for long-term planning
The Infrastructure Pipeline was first launched in July 2025 as part of the government’s broader effort to provide greater certainty to investors and industry. This latest update expands both the number of projects and the level of detail available to suppliers across the infrastructure ecosystem.
For rail companies, clearer forward visibility can influence everything from recruitment and training programmes to investment in equipment, technology and supply chain partnerships.
The revised Pipeline now contains £718 billion in capital investment, a significant increase compared with earlier projections. The change partly reflects improved data collection from a wider range of project sponsors, including several Mayoral Combined Authorities.
While energy remains the sector with the largest investment commitment – with around £365 billion planned over ten years – transport projects continue to form a core part of the national infrastructure programme. For rail suppliers, this long-term planning framework offers a stronger signal about where opportunities may emerge across major schemes, regional upgrades and network improvements.
Crucially, the Pipeline has also been redesigned to improve its usefulness as a commercial planning tool. Firms can now access more detailed project metrics, including information about the types of investment sought, potential funding models and the structure of future opportunities.
Linking infrastructure delivery with skills
One of the most significant additions is the integration of workforce forecasting. For rail companies competing for skilled labour across engineering, construction and digital disciplines, this could help inform long-term recruitment and training strategies.
Chief Secretary to the Treasury James Murray emphasised the role infrastructure investment will play in strengthening the wider economy. He said: “We have the right economic plan to build a stronger and more secure economy. Transforming this country’s infrastructure is a vital part of that plan and will create high-quality jobs right across the country.
“As part of this latest version of the Infrastructure Pipeline, we’re also giving the construction sector the detailed picture it needs to invest in a highly skilled workforce that’s primed to build the hospitals, schools, railways, reservoirs and renewable energy plants this country needs.”
For rail companies, this connection between future projects and workforce demand could help reduce one of the industry’s biggest risks: delivery bottlenecks caused by shortages of experienced engineers, technicians and project specialists.
Becky Wood, CEO of the National Infrastructure and Service Transformation Authority, said the update reflects feedback from industry on what information businesses need to plan effectively. She said: “Transforming UK infrastructure needs a three-way collaboration between government, investors, and industry to succeed. The Infrastructure Pipeline is the foundation on which this relationship thrives, and this update now gives investors more granular information about forthcoming investable opportunities they told us they need for their strategic planning.
“Our industry partners across the sector can only invest in new skills, capacity and technology with the right data to assess what the Pipeline means in the delivery context. By adding new information on what future workforce demand looks like they can plan with confidence, and the Pipeline is also better placed to support the investment government is already making to address the construction skills gap.”
What it means for the rail supply chain
For the rail sector, the Pipeline update reinforces several key themes already shaping the industry.
First, demand for skills will intensify. Major rail programmes – from network renewals to regional upgrades and potential new lines – will compete for the same engineering and construction talent as projects in energy, housing and utilities.
Second, long-term workforce planning will become essential. Rail companies that invest early in apprenticeships, training and partnerships with education providers will be better positioned to secure talent as infrastructure delivery accelerates.
Third, supply chain capacity will remain a critical factor. Many rail projects rely on specialist contractors and SMEs whose ability to scale will influence overall delivery performance.
Industry leaders have broadly welcomed the updated Pipeline as a positive step towards providing the clarity businesses have long requested.
Association for Consultancy and Engineering (ACE) CEO Milda Manomaityte said: “This updated pipeline marks a significant step forward, giving industry and investors the clarity and certainty ACE members have been asking for. Stronger commercial metrics, richer regional data, and clearer investment models are vital to our sector and provide the confidence for ACE members to plan, invest and drive growth right across the UK.
“Enhanced workforce insights and more robust project data demonstrate tangible progress towards a transparent, credible, and delivery-focused programme. Continued momentum in future releases will be key to sustaining investment, supporting jobs, and ensuring infrastructure delivery keeps pace with ambition.”
Richard Whitehead, Chief Executive for AECOM’s Europe and India region, also highlighted the importance of workforce forecasting in improving delivery confidence. He said: “Since its establishment, the National Infrastructure and Service Transformation Authority (NISTA) has provided strong leadership for our industry, including through the publication of a clear 10-Year Infrastructure Strategy and project pipeline. The updated pipeline, unveiled today, represents an important step forward – particularly through the welcome addition of workforce requirements. It will help businesses plan with greater confidence, reduce potential delivery bottlenecks and provide a clearer signal of the skills, investment and partnerships that will be needed to deliver the infrastructure our country will require in the years ahead.
“AECOM is proud to have advised on the development of the next iteration of the pipeline and we stand ready to continue supporting government in realising its infrastructure ambitions. The establishment of NISTA, alongside the reforms introduced through the Planning & Infrastructure Act, are clear signals of the government’s intent to bring greater structure to the infrastructure system and accelerate delivery. The real test will now be turning this ambition into projects on the ground – and industry is ready to play its part.”
Turning ambition into delivery
Ultimately, the value of the Infrastructure Pipeline will depend on how effectively the information translates into real delivery on the ground – and how the work is distributed.
Costain Chief Executive Alex Vaughan described the update as a strong signal about the country’s long-term ambitions. He said: “Today’s update of the Infrastructure Pipeline sends a powerful signal about the UK’s long-term infrastructure ambitions. With investment clearly mapped out, business leaders have greater visibility over future projects that will help create a more prosperous, resilient and decarbonised UK. The opportunity now is to ensure this ambition goes hand-in-hand with long-term workforce planning so that the industry has the right skills and people in place for the successful delivery of critical national infrastructure.”
Mark Reynolds, Executive Chairman of Mace Group and Co-Chair of the Construction Skills Mission Board, said the addition of workforce data could play a key role in shaping future training systems. He said: “The new National Construction and Infrastructure Pipeline has already proved invaluable to industry, giving clarity and visibility of workload at a time when confidence in future delivery is so important. We commend NISTA for its achievement and believe the new skills data set will help further; enabling industry and government to establish a demand-led skills system that identifies where and what skills and jobs are required to deliver the pipeline. We look forward to working with NISTA to further develop and refine the pipeline tool; it will be a key part of the work the Construction Skills Mission Board is driving to ensure that every person who wants to join the construction sector is able to find a long-term, sustainable job.”
For rail suppliers, the message is straightforward: the opportunities ahead are significant, but so are the challenges.
Skanska UK President and CEO Katy Dowding said the connection between infrastructure planning and workforce development could help move the industry from ambition to delivery. She said: “Today’s publication of the updated infrastructure pipeline is very welcome, and a clear demonstration of the value governments can drive by engaging with industry to identify and evolve critical infrastructure opportunities. Having a pipeline is good, having funding is even better, but what really stands out for me is the critical link that has been made between pipeline and skills.
“By identifying what skills are needed where, and focusing efforts accordingly, government and industry have a roadmap that can really start the shift from policy to delivery. As a member of the Construction Skills Mission Board whose mission is to recruit 100,000 additional construction workers and tackle the skills shortage, I think this sets us on a great path forward. Whilst today’s update might not provide a detailed playbook of the infrastructure programme for the next 10 years, it certainly enables businesses like mine to get on the front foot with planning and resourcing for the future.
“A great example of that is having clarity on the ambitions and funding for schemes in areas such as the East of England. Here, we see great opportunity for regions that really need committed investment to meet their growth and economic performance ambitions.”
For the UK rail sector, the Pipeline update does not simply outline future projects. It highlights a more immediate challenge: ensuring the industry has the people, partnerships and capacity required to deliver them.
