The UK construction industry posted its fourth consecutive year of growth. Output increased 0.4% in 2024 compared to 2023, according to February 2025 ONS data.
Yet beneath this growth lies a sector grappling with severe structural problems. Productivity hasn’t moved in 50 years. Building costs are climbing 17% over the next five years. The industry needs 225,000 new workers by 2027 to meet government targets.
The Productivity Paradox That Won’t Go Away
Construction output per hour has barely changed since 1970.
While output per hour across the wider UK labor market has more than doubled in the same period, construction has stayed flat for half a century.
This affects project timelines, profit margins, and the industry’s ability to deliver on housing and infrastructure commitments.
When you can’t do more with the same resources, you need more resources to do the same amount. This creates higher costs, longer timelines, and increased pressure on thin margins.
The Cost Squeeze
Building costs will rise 17% over the next five years, according to the BCIS Building Construction Industry Forecast. Tender prices will climb even faster at 19%.
The gap between building costs and tender prices shows contractors are pricing in risk, uncertainty, and expected cost increases.
Annual construction output price growth hit 3.0% in the 12 months to December 2024. Combined with skills shortages, flat productivity, and rising material costs, this changes project economics.
Factor cost inflation into every project timeline and budget.
The Skills Crisis
The industry needs 225,000 new construction workers by 2027 to meet government targets for housing and net zero retrofits.
HVAC technicians account for more than 59,000 of those unfilled roles. This threatens the UK’s decarbonization strategy for construction.
The skills shortage drives wage inflation. Wage inflation drives tender price increases. Higher tender prices make projects less viable. Less viable projects mean fewer starts. Fewer starts mean less industry capacity exactly when the country needs more.
The Construction Skills Network 2023-2027 report confirms this is a structural challenge for the rest of the decade.
The Sustainability Shift
The sustainability in construction market is growing at 8.91% CAGR through 2031.
70% of construction projects now incorporate sustainability targets. 64% of professionals worked on a net-zero project in the past year, up from 49% in 2022.
Sustainability is embedded in project requirements, client expectations, and regulatory frameworks.
The challenge is delivering on sustainability commitments while managing cost pressures and skills shortages. Retrofitting the UK’s building stock to net zero requires HVAC technicians the industry doesn’t have. Meeting sustainability targets becomes harder as building costs climb 17%.
Digital Transformation
Digital transformation is accelerating to bridge the productivity gap.
The Chartered Institute of Building estimates robotics in construction could increase productivity by 25%.
Digital tools are transforming project management, design, and construction processes. Technology can help offset costs as BCIS predicts a 17% rise in building costs over the next five years.
Technology adoption varies. Some firms use digital tools for competitive advantage. Others operate with legacy systems.
The gap between leaders and laggards will show in project delivery times, cost control, and market share.
Infrastructure and Industrial Growth
While overall construction growth remains modest, the industrial sector posted a 45% increase in project starts over three months, a 27% rise compared to last year. Civil engineering projects showed an 18% rise in starts, with infrastructure jumping 36% year-over-year.
Major projects like Old Oak Common Station in London are driving infrastructure growth. These large-scale developments create momentum and employment, but they also concentrate resources in specific geographic areas and project types.
The uneven distribution of growth creates challenges for smaller contractors and regional firms that don’t have access to major infrastructure projects.
What This Means for Your Projects
The sector is expected to return to a growth rate of 2.9% in 2025, but aggregate growth doesn’t guarantee success for individual projects or firms.
To navigate these pressures, account for cost inflation in budgets, plan for skills shortages in timelines, and incorporate sustainability requirements from the start. Digital transformation isn’t optional—it’s where competitive advantage will be won or lost.
The industry is growing, but the structural challenges are intensifying. How firms respond to productivity stagnation, cost inflation, skills shortages, and technology adoption will separate winners from those left behind.
