Recently, the UK Construction Blog released a report that found a promising infrastructure pipeline worth £530 billion; driving optimism across the sector and projecting significant growth throughout the coming decade.
The report, which consolidates figures from key construction industry bodies such as CIBT and Glenigan suggests output is expected to increase by up to 4.4%, benefiting from a £530 billion pipeline of public and private projects from now until 2036.
And, given how rough the last few years have been for the construction industry as a whole – often exacerbated by external factors such as COVID-19 and ongoing conflicts in Europe and the Middle East, these figures are incredibly encouraging; showcasing the almighty resilience and necessity of this cornerstone industry.
However, alongside the positive stats – the forecasted 2-3% growth of logistical and industrial construction, the 4% growth of private housing – is a very concerning figure that could very well cast a dark shadow over all of this: a 266,000 workforce shortage that must be filled by the end of 2026.
If the £530 billion pipeline is to be delivered, we need over a quarter of a million people to join the construction workforce. But why is there such a significant shortage and what effect could this have on the industry?
Where the 266,000 Workforce Shortage Comes From
There are multiple reasons why the industry is suffering from such a significant shortage, including:
COVID-19: lockdowns during the 2020/21 COVID-19 pandemic led to a lost generation of training and apprenticeships, alongside a large proportion of the workforce who fled the cities where they’re most needed, for more rural, affordable and ‘quiet’ areas of the country.
Aging Out: a hefty 35% of the current workforce is over the age of 50, where only around 19% of the workforce is under 30; meaning that 750,000 people will retire by the year 2036, taking with them any specialist knowledge and experience.
Autumn Budget Complications: the rising minimum wage and National Insurance contributions announced in the Autumn Budget of 2025 has made the sector less attractive to new entrants and riskier for small contractors.
The Uncertainty Of A Significant Workforce Shorage
And, for investors and developers, this shortage will inevitably lead to a number of uncertainties, challenges and cost implications that perhaps are missing in the wider conversation.
As the workforce declines and wages increase, project timelines are vulnerable to slippage and interest accumulation, meaning margins thin, making otherwise promising projects look less and less viable. For a project to be viable and attractive to an investor, it needs to make money, or at the very least, break even. With higher costs and increased uncertainty, comes much less “bankability”, which could leave a lot of projects falling by the wayside – i.e. failing at the pre-construction phase and never making it to breaking ground.
But, there’s more. Specifically, we’re losing, not just ‘boots on the ground’ so to speak, we’re losing specialists and middle-management; civil engineers, high pressure gas engineers, and process engineers, to name but a few – specialised and highly skilled professionals essential to renewable energy projects and large, complex infrastructure developments – those that drive a complex project forward in the most efficient way possible.
The Solution To The Problem
So, with all this in mind, what’s the solution to this looming problem, to keep project costs down, ensure project viability and cover the 266,000 workforce shortage?
Government Responsibility: realistically, the government has a responsibility to incentivise specialist training and education in the construction industry; we need apprenticeship levies repurposed for Strategic Green Skills, alongside tax credits for company-led training, which are arguably as important as subsidies for the energy itself.
Early Engagement: in a 266,000-person deficit, the “early bird gets the worm.” That is to say, securing due diligence, feasibility and delivery teams before the project is fully green-lit is now a commercial necessity to ensure project viability.
Smart Design: projects that focus on ‘Resilience by Design’ – choosing construction methods (like modular builds) that require less specialised on-site labor can confidently bypass the shortage.
Smart Sites and Automation: If we cannot find the bodies to fill the gap, we must look to the technology that can bridge it. The rise of ‘Smart Sites’ – utilising remote project management, autonomous machinery, and real-time digital twins – is no longer a futuristic luxury but a strategic necessity. By automating repetitive or high-risk tasks, we don’t just reduce the headcount required on-site; we increase precision and safety.
Reaching The £530 Billion Target
A £530 billion pipeline is a map, not a destination and, to reach the goals set out for 2036, the industry must stop treating construction labour as a general commodity and start treating it as a strategic national asset. Energy security isn’t just about the gas in the pipes; it’s about the hands – and the technology – that put them there.
