The UK construction industry is navigating 2026 with a mixed outlook.
There are significant opportunities ahead, with major investment planned across infrastructure, housing, energy, utilities and public services. At the same time, the industry is facing a more challenging short-term environment, with subdued demand, falling new orders, cost pressures and continued skills shortages.
So, what is actually happening across the UK construction market, and what could it mean for the industry over the coming years?

Below, we look at the trends behind those numbers and what they mean for contractors, architects and builders merchants.
Construction activity remains challenging
The latest figures show just how uneven the current market is.
According to the Office for National Statistics (ONS), construction output in Great Britain fell by 1.0% in the three months to August 2026, following a previous decline. New work fell by 1.4%, while repair and maintenance decreased by 0.3%. Private new housing was one of the biggest contributors to the decline, falling by 3.2% over the period.
The picture is therefore more complicated than simply saying the UK construction industry is growing or shrinking.
Some areas of the market are under significant pressure, while others are showing greater resilience.
Infrastructure, energy, utilities and other major public investment programmes are helping to support activity, while parts of the private residential and commercial markets continue to face challenges around viability, financing and demand.
Housing remains a major priority
Housing continues to be one of the biggest issues facing the UK construction sector.
In England, 35,910 new-build dwellings started construction in Q2 2026, a 20% increase compared with the same quarter in 2025. However, starts remained significantly below their previous peak, demonstrating that the recovery is still some way from being complete (UK Government Housing Supply Statistics).
Government-backed housing programmes are also increasing activity. Homes England reported more than 42,400 housing starts and more than 40,300 completions through its programmes during 2025/26.
But delivering the homes the UK needs will require more than simply increasing targets.
Land availability, planning, development viability, finance, labour and supply chain capacity all play a role in determining whether planned homes actually become completed homes.
Infrastructure is one of the biggest opportunities
While parts of the construction market are subdued, infrastructure is emerging as an important source of long-term opportunity.
The UK Infrastructure Pipeline includes 734 projects representing around £718 billion of planned public and private investment over the next decade. The pipeline covers areas including transport, utilities, energy, health, education and defence.
The scale of this pipeline presents a significant opportunity for the construction industry.
However, delivering it will also put pressure on the industry’s ability to provide the people, skills, materials and specialist expertise required.
The government estimates that delivering the infrastructure pipeline will require an average construction and infrastructure workforce of between 629,000 and 706,000 people each year over the next five years.
That brings one of the industry’s biggest challenges into focus: capacity.
Skills and workforce remain a major concern
The UK construction industry has been dealing with skills shortages for years, and the issue is not disappearing.
The latest CITB Construction Workforce Outlook 2026–2030 highlights continued pressure around recruiting and retaining the workforce needed by the industry. While demand is expected to strengthen over the medium term, the sector needs to attract new entrants, train workers and replace people leaving the industry.
This becomes particularly important when housing, infrastructure, energy and other major programmes are competing for many of the same skills.
The challenge isn’t simply having enough workers. It is having the right skills in the right places at the right time to deliver increasingly complex projects.
Construction costs are still putting pressure on projects
Cost remains another major consideration for the UK construction industry.
The latest BCIS Construction Industry Forecast expects building costs to increase by around 14% over the five years to Q3 2031, with tender prices forecast to rise by a similar 14.1%.
While this represents a more moderate outlook than the sharp cost increases seen earlier in the decade, construction costs remain under pressure from energy, materials and labour.
There is also an important difference between input costs and the prices contractors are able to charge. With demand relatively subdued and competition for available work remaining strong, contractors are absorbing or mitigating some cost increases rather than passing them fully on to clients.
This creates a difficult environment for everyone involved in a project:
- Clients want cost certainty and value.
- Contractors need to protect margins while managing rising input costs.
- The supply chain needs to balance availability, price and performance.
As demand begins to recover, the question will be how much of the cost pressure currently being absorbed by contractors eventually feeds through into project pricing.
For the industry, this makes careful cost planning, product selection and supply chain management increasingly important.

Building performance is becoming increasingly important
Cost pressures are not the only consideration facing the construction industry.
Expectations around energy efficiency, sustainability, fire safety, acoustic performance and the overall performance of buildings continue to grow. For contractors, developers, architects and building professionals, choosing the right materials and products is becoming increasingly important.
The focus is increasingly moving beyond simply asking “What does it cost?” and towards “Does it deliver the performance the building requires?”
This is particularly relevant as the UK continues to focus on improving energy efficiency and reducing the carbon impact of buildings.
The market may be challenging, but the long-term opportunity is significant
The UK construction industry is currently navigating a difficult combination of weaker demand, falling new orders and continued cost pressures.
The latest ONS figures show construction output declining, while industry forecasts point towards a gradual rather than rapid recovery.
But looking beyond the immediate market, there are significant opportunities:
- Housing demand remains high.
- Infrastructure investment is substantial.
- Energy and utilities projects are creating new workloads.
- Public investment is supporting parts of the market.
- The need to improve the performance and efficiency of buildings is continuing to grow.
The challenge for the industry will be turning that long-term opportunity into projects that can actually be delivered.
What does this mean for the construction industry?
The next few years are likely to be about much more than simply increasing construction output. The industry will need to find ways to:
- Deliver more housing
- Progress major infrastructure programmes
- Address skills and workforce shortages
- Manage material and labour costs
- Improve productivity
- Strengthen supply chain resilience
- Meet increasingly demanding building performance requirements
- Deliver projects efficiently while maintaining quality
For everyone across the construction supply chain, understanding these changes will be increasingly important.
